-# How to Contribute
-
-Flagger is [Apache 2.0 licensed](LICENSE) and accepts contributions via GitHub
-pull requests. This document outlines some of the conventions on development
-workflow, commit message formatting, contact points and other resources to make
-it easier to get your contribution accepted.
-
-We gratefully welcome improvements to documentation as well as to code.
-
-## Certificate of Origin
-
-By contributing to this project you agree to the Developer Certificate of
-Origin (DCO). This document was created by the Linux Kernel community and is a
-simple statement that you, as a contributor, have the legal right to make the
-contribution.
-
-## Chat
-
-The project uses Slack: To join the conversation, simply join the
-[Weave community](https://slack.weave.works/) Slack workspace.
-
-## Getting Started
-
-- Fork the repository on GitHub
-- If you want to contribute as a developer, continue reading this document for further instructions
-- If you have questions, concerns, get stuck or need a hand, let us know
-  on the Slack channel. We are happy to help and look forward to having
-  you part of the team. No matter in which capacity.
-- Play with the project, submit bugs, submit pull requests!
-
-## Contribution workflow
-
-This is a rough outline of how to prepare a contribution:
-
-- Create a topic branch from where you want to base your work (usually branched from master).
-- Make commits of logical units.
-- Make sure your commit messages are in the proper format (see below).
-- Push your changes to a topic branch in your fork of the repository.
-- If you changed code:
-  - add automated tests to cover your changes
-- Submit a pull request to the original repository.
-
-## Acceptance policy
-
-These things will make a PR more likely to be accepted:
-
-- a well-described requirement
-- new code and tests follow the conventions in old code and tests
-- a good commit message (see below)
-- All code must abide [Go Code Review Comments](https://github.com/golang/go/wiki/CodeReviewComments)
-- Names should abide [What's in a name](https://talks.golang.org/2014/names.slide#1)
-- Code must build on both Linux and Darwin, via plain `go build`
-- Code should have appropriate test coverage and tests should be written
-  to work with `go test`
-
-In general, we will merge a PR once one maintainer has endorsed it.
-For substantial changes, more people may become involved, and you might
-get asked to resubmit the PR or divide the changes into more than one PR.
-
-### Format of the Commit Message
-
-For Flux we prefer the following rules for good commit messages:
-
-- Limit the subject to 50 characters and write as the continuation
-  of the sentence "If applied, this commit will ..."
-- Explain what and why in the body, if more than a trivial change;
-  wrap it at 72 characters.
-
-The [following article](https://chris.beams.io/posts/git-commit/#seven-rules)
-has some more helpful advice on documenting your work.
-
-This doc is adapted from the [Weaveworks Flux](https://github.com/weaveworks/flux/blob/master/CONTRIBUTING.md)

-Flagger is a Kubernetes operator that automates the promotion of canary deployments
-using Istio routing for traffic shifting and Prometheus metrics for canary analysis. 
-The canary analysis can be extended with webhooks for running integration tests, 
-load tests or any other custom validation.
-
-### Install 
-
-Before installing Flagger make sure you have Istio setup up with Prometheus enabled. 
-If you are new to Istio you can follow my [Istio service mesh walk-through](https://github.com/stefanprodan/istio-gke).
-
-Deploy Flagger in the `istio-system` namespace using Helm:
-
-```bash
-# add the Helm repository
-helm repo add flagger https://flagger.app
-
-# install or upgrade
-helm upgrade -i flagger flagger/flagger \
---namespace=istio-system \
---set metricsServer=http://prometheus.istio-system:9090 
-```
-
-Flagger is compatible with Kubernetes >1.11.0 and Istio >1.0.0.
-
-### Usage
-
-Flagger takes a Kubernetes deployment and creates a series of objects 
-(Kubernetes [deployments](https://kubernetes.io/docs/concepts/workloads/controllers/deployment/), 
-ClusterIP [services](https://kubernetes.io/docs/concepts/services-networking/service/) and 
-Istio [virtual services](https://istio.io/docs/reference/config/istio.networking.v1alpha3/#VirtualService)) 
-to drive the canary analysis and promotion.
-
-Flagger keeps track of ConfigMaps and Secrets referenced by a Kubernetes Deployment and triggers a canary analysis if any of those objects change. 
-When promoting a workload in production, both code (container images) and configuration (config maps and secrets) are being synchronised.
-
-![flagger-overview](https://raw.githubusercontent.com/stefanprodan/flagger/master/docs/diagrams/flagger-canary-overview.png)
-
-Gated canary promotion stages:
-
-* scan for canary deployments
-* check Istio virtual service routes are mapped to primary and canary ClusterIP services
-* check primary and canary deployments status
-    * halt advancement if a rolling update is underway
-    * halt advancement if pods are unhealthy
-* increase canary traffic weight percentage from 0% to 5% (step weight)
-* call webhooks and check results
-* check canary HTTP request success rate and latency
-    * halt advancement if any metric is under the specified threshold
-    * increment the failed checks counter
-* check if the number of failed checks reached the threshold
-    * route all traffic to primary
-    * scale to zero the canary deployment and mark it as failed
-    * wait for the canary deployment to be updated and start over
-* increase canary traffic weight by 5% (step weight) till it reaches 50% (max weight) 
-    * halt advancement while canary request success rate is under the threshold
-    * halt advancement while canary request duration P99 is over the threshold
-    * halt advancement if the primary or canary deployment becomes unhealthy 
-    * halt advancement while canary deployment is being scaled up/down by HPA
-* promote canary to primary
-    * copy ConfigMaps and Secrets from canary to primary
-    * copy canary deployment spec template over primary
-* wait for primary rolling update to finish
-    * halt advancement if pods are unhealthy
-* route all traffic to primary
-* scale to zero the canary deployment
-* mark rollout as finished
-* wait for the canary deployment to be updated and start over
-
-For a deployment named _podinfo_, a canary promotion can be defined using Flagger's custom resource:
-
-```yaml
-apiVersion: flagger.app/v1alpha3
-kind: Canary
-metadata:
-  name: podinfo
-  namespace: test
-spec:
-  # deployment reference
-  targetRef:
-    apiVersion: apps/v1
-    kind: Deployment
-    name: podinfo
-  # the maximum time in seconds for the canary deployment
-  # to make progress before it is rollback (default 600s)
-  progressDeadlineSeconds: 60
-  # HPA reference (optional)
-  autoscalerRef:
-    apiVersion: autoscaling/v2beta1
-    kind: HorizontalPodAutoscaler
-    name: podinfo
-  service:
-    # container port
-    port: 9898
-    # Istio gateways (optional)
-    gateways:
-    - public-gateway.istio-system.svc.cluster.local
-    # Istio virtual service host names (optional)
-    hosts:
-    - podinfo.example.com
-  canaryAnalysis:
-    # schedule interval (default 60s)
-    interval: 1m
-    # max number of failed metric checks before rollback
-    threshold: 10
-    # max traffic percentage routed to canary
-    # percentage (0-100)
-    maxWeight: 50
-    # canary increment step
-    # percentage (0-100)
-    stepWeight: 5
-    # Istio Prometheus checks
-    metrics:
-    - name: istio_requests_total
-      # minimum req success rate (non 5xx responses)
-      # percentage (0-100)
-      threshold: 99
-      interval: 1m
-    - name: istio_request_duration_seconds_bucket
-      # maximum req duration P99
-      # milliseconds
-      threshold: 500
-      interval: 30s
-    # external checks (optional)
-    webhooks:
-      - name: load-test
-        url: http://flagger-loadtester.test/
-        timeout: 5s
-        metadata:
-          cmd: "hey -z 1m -q 10 -c 2 http://podinfo.test:9898/"
-```
-
-The canary analysis is using the following promql queries:
- 
-_HTTP requests success rate percentage_
-
-```sql
-sum(
-    rate(
-        istio_requests_total{
-          reporter="destination",
-          destination_workload_namespace=~"$namespace",
-          destination_workload=~"$workload",
-          response_code!~"5.*"
-        }[$interval]
-    )
-) 
-/ 
-sum(
-    rate(
-        istio_requests_total{
-          reporter="destination",
-          destination_workload_namespace=~"$namespace",
-          destination_workload=~"$workload"
-        }[$interval]
-    )
-)
-```
-
-_HTTP requests milliseconds duration P99_
-
-```sql
-histogram_quantile(0.99, 
-  sum(
-    irate(
-      istio_request_duration_seconds_bucket{
-        reporter="destination",
-        destination_workload=~"$workload",
-        destination_workload_namespace=~"$namespace"
-      }[$interval]
-    )
-  ) by (le)
-)
-```
-
-The canary analysis can be extended with webhooks. 
-Flagger will call the webhooks (HTTP POST) and determine from the response status code (HTTP 2xx) if the canary is failing or not.
-
-Webhook payload:
-
-```json
-{
-    "name": "podinfo",
-    "namespace": "test", 
-    "metadata": {
-        "test":  "all",
-        "token":  "16688eb5e9f289f1991c"
-    }
-}
-```
-
-### Automated canary analysis, promotions and rollbacks
-
-Create a test namespace with Istio sidecar injection enabled:
-
-```bash
-export REPO=https://raw.githubusercontent.com/stefanprodan/flagger/master
-
-kubectl apply -f ${REPO}/artifacts/namespaces/test.yaml
-```
-
-Create a deployment and a horizontal pod autoscaler:
-
-```bash
-kubectl apply -f ${REPO}/artifacts/canaries/deployment.yaml
-kubectl apply -f ${REPO}/artifacts/canaries/hpa.yaml
-```
-
-Deploy the load testing service to generate traffic during the canary analysis:
-
-```bash
-kubectl -n test apply -f ${REPO}/artifacts/loadtester/deployment.yaml
-kubectl -n test apply -f ${REPO}/artifacts/loadtester/service.yaml
-```
-
-Create a canary promotion custom resource (replace the Istio gateway and the internet domain with your own):
-
-```bash
-kubectl apply -f ${REPO}/artifacts/canaries/canary.yaml
-```
-
-After a couple of seconds Flagger will create the canary objects:
-
-```bash
-# applied 
-deployment.apps/podinfo
-horizontalpodautoscaler.autoscaling/podinfo
-canary.flagger.app/podinfo
-# generated 
-deployment.apps/podinfo-primary
-horizontalpodautoscaler.autoscaling/podinfo-primary
-service/podinfo
-service/podinfo-canary
-service/podinfo-primary
-virtualservice.networking.istio.io/podinfo
-```
-
-![flagger-canary-steps](https://raw.githubusercontent.com/stefanprodan/flagger/master/docs/diagrams/flagger-canary-steps.png)
-
-Trigger a canary deployment by updating the container image:
-
-```bash
-kubectl -n test set image deployment/podinfo \
-podinfod=quay.io/stefanprodan/podinfo:1.4.0
-```
-
-**Note** that Flagger tracks changes in the deployment `PodSpec` but also in `ConfigMaps` and `Secrets` 
-that are referenced in the pod's volumes and containers environment variables.
-
-Flagger detects that the deployment revision changed and starts a new canary analysis:
-
-```
-kubectl -n test describe canary/podinfo
-
-Status:
-  Canary Weight:         0
-  Failed Checks:         0
-  Last Transition Time:  2019-01-16T13:47:16Z

-```
-
-You can monitor all canaries with:
-
-```bash
-watch kubectl get canaries --all-namespaces
-
-NAMESPACE   NAME      STATUS        WEIGHT   LASTTRANSITIONTIME
-test        podinfo   Progressing   5        2019-01-16T14:05:07Z
-```
-
-During the canary analysis you can generate HTTP 500 errors and high latency to test if Flagger pauses the rollout.
-
-Create a tester pod and exec into it:
-
-```bash
-kubectl -n test run tester --image=quay.io/stefanprodan/podinfo:1.2.1 -- ./podinfo --port=9898
-kubectl -n test exec -it tester-xx-xx sh
-```
-
-Generate HTTP 500 errors:
-
-```bash
-watch curl http://podinfo-canary:9898/status/500
-```
-
-Generate latency:
-
-```bash
-watch curl http://podinfo-canary:9898/delay/1
-```
-
-When the number of failed checks reaches the canary analysis threshold, the traffic is routed back to the primary,
-the canary is scaled to zero and the rollout is marked as failed. 
-
-```
-kubectl -n test describe canary/podinfo
-
-Status:

-```
-
-**Note** that if you apply new changes to the deployment during the canary analysis, Flagger will restart the analysis.
-
-### Monitoring
-
-Flagger comes with a Grafana dashboard made for canary analysis.
-
-Install Grafana with Helm:
-
-```bash
-helm upgrade -i flagger-grafana flagger/grafana \
---namespace=istio-system \
---set url=http://prometheus.istio-system:9090
-```
-
-The dashboard shows the RED and USE metrics for the primary and canary workloads:
-
-![flagger-grafana](https://raw.githubusercontent.com/stefanprodan/flagger/master/docs/screens/grafana-canary-analysis.png)
-
-The canary errors and latency spikes have been recorded as Kubernetes events and logged by Flagger in json format:
-
-```
-kubectl -n istio-system logs deployment/flagger --tail=100 | jq .msg
-
-Starting canary deployment for podinfo.test
-Advance podinfo.test canary weight 5
-Advance podinfo.test canary weight 10
-Advance podinfo.test canary weight 15
-Advance podinfo.test canary weight 20
-Advance podinfo.test canary weight 25
-Advance podinfo.test canary weight 30
-Advance podinfo.test canary weight 35
-Halt podinfo.test advancement success rate 98.69% < 99%
-Advance podinfo.test canary weight 40

-```
-
-Flagger exposes Prometheus metrics that can be used to determine the canary analysis status and the destination weight values:
-
-```bash
-# Canaries total gauge
-flagger_canary_total{namespace="test"} 1
-
-# Canary promotion last known status gauge
-# 0 - running, 1 - successful, 2 - failed
-flagger_canary_status{name="podinfo" namespace="test"} 1
-
-# Canary traffic weight gauge
-flagger_canary_weight{workload="podinfo-primary" namespace="test"} 95
-flagger_canary_weight{workload="podinfo" namespace="test"} 5
-
-# Seconds spent performing canary analysis histogram
-flagger_canary_duration_seconds_bucket{name="podinfo",namespace="test",le="10"} 6
-flagger_canary_duration_seconds_bucket{name="podinfo",namespace="test",le="+Inf"} 6
-flagger_canary_duration_seconds_sum{name="podinfo",namespace="test"} 17.3561329
-flagger_canary_duration_seconds_count{name="podinfo",namespace="test"} 6
-```
-
-### Alerting
-
-Flagger can be configured to send Slack notifications:
-
-```bash
-helm upgrade -i flagger flagger/flagger \
---namespace=istio-system \
---set slack.url=https://hooks.slack.com/services/YOUR/SLACK/WEBHOOK \
---set slack.channel=general \
---set slack.user=flagger
-```
-
-Once configured with a Slack incoming webhook, Flagger will post messages when a canary deployment has been initialized,
-when a new revision has been detected and if the canary analysis failed or succeeded.
-
-![flagger-slack](https://raw.githubusercontent.com/stefanprodan/flagger/master/docs/screens/slack-canary-notifications.png)
-
-A canary deployment will be rolled back if the progress deadline exceeded or if the analysis 
-reached the maximum number of failed checks:
-
-![flagger-slack-errors](https://raw.githubusercontent.com/stefanprodan/flagger/master/docs/screens/slack-canary-failed.png)
-
-Besides Slack, you can use Alertmanager to trigger alerts when a canary deployment failed:
-
-```yaml
-  - alert: canary_rollback
-    expr: flagger_canary_status > 1
-    for: 1m
-    labels:
-      severity: warning
-    annotations:
-      summary: "Canary failed"
-      description: "Workload {{ $labels.name }} namespace {{ $labels.namespace }}"
-```
-
-### Roadmap
-
-* Extend the validation mechanism to support other metrics than HTTP success rate and latency
-* Add support for comparing the canary metrics to the primary ones and do the validation based on the derivation between the two
-* Extend the canary analysis and promotion to other types than Kubernetes deployments such as Flux Helm releases or OpenFaaS functions
-
-### Contributing
-
-Flagger is Apache 2.0 licensed and accepts contributions via GitHub pull requests.
-
-When submitting bug reports please include as much details as possible: 
-* which Flagger version
-* which Flagger CRD version
-* which Kubernetes/Istio version
-* what configuration (canary, virtual service and workloads definitions)
-* what happened (Flagger, Istio Pilot and Proxy logs)

-# Flagger
-
-[Flagger](https://github.com/stefanprodan/flagger) is a Kubernetes operator that automates the promotion of 
-canary deployments using Istio routing for traffic shifting and Prometheus metrics for canary analysis. 
-Flagger implements a control loop that gradually shifts traffic to the canary while measuring key performance indicators
-like HTTP requests success rate, requests average duration and pods health.
-Based on the KPIs analysis a canary is promoted or aborted and the analysis result is published to Slack.
-
-## Prerequisites
-
-* Kubernetes >= 1.11
-* Istio >= 1.0
-* Prometheus >= 2.6
-
-## Installing the Chart
-
-Add Flagger Helm repository:
-
-```console
-helm repo add flagger https://flagger.app
-```
-
-To install the chart with the release name `flagger`:
-
-```console
-$ helm install --name flagger --namespace istio-system flagger/flagger
-```
-
-The command deploys Flagger on the Kubernetes cluster in the istio-system namespace.
-The [configuration](#configuration) section lists the parameters that can be configured during installation.
-
-## Uninstalling the Chart
-
-To uninstall/delete the `flagger` deployment:
-
-```console
-$ helm delete --purge flagger
-```
-
-The command removes all the Kubernetes components associated with the chart and deletes the release.
-
-## Configuration
-
-The following tables lists the configurable parameters of the Flagger chart and their default values.
-
-Parameter | Description | Default
---- | --- | ---
-`image.repository` | image repository | `quay.io/stefanprodan/flagger`
-`image.tag` | image tag | `<VERSION>`
-`image.pullPolicy` | image pull policy | `IfNotPresent`
-`metricsServer` | Prometheus URL | `http://prometheus.istio-system:9090`
-`slack.url` | Slack incoming webhook | None
-`slack.channel` | Slack channel | None
-`slack.user` | Slack username | `flagger`
-`rbac.create` | if `true`, create and use RBAC resources | `true`
-`crd.create` | if `true`, create Flagger's CRDs | `true`
-`resources.requests/cpu` | pod CPU request | `10m`
-`resources.requests/memory` | pod memory request | `32Mi`
-`resources.limits/cpu` | pod CPU limit | `1000m`
-`resources.limits/memory` | pod memory limit | `512Mi`
-`affinity` | node/pod affinities | None
-`nodeSelector` | node labels for pod assignment | `{}`
-`tolerations` | list of node taints to tolerate | `[]`
-
-Specify each parameter using the `--set key=value[,key=value]` argument to `helm upgrade`. For example,
-
-```console
-$ helm upgrade -i flagger flagger/flagger \
-  --namespace istio-system \
-  --set slack.url=https://hooks.slack.com/services/YOUR/SLACK/WEBHOOK \
-  --set slack.channel=general
-```
-
-Alternatively, a YAML file that specifies the values for the above parameters can be provided while installing the chart. For example,
-
-```console
-$ helm upgrade -i flagger flagger/flagger \
-  --namespace istio-system \
-  -f values.yaml
-```
-
-> **Tip**: You can use the default [values.yaml](values.yaml)

-# Flagger Grafana
-
-Grafana dashboards for monitoring progressive deployments powered by Istio, Prometheus and Flagger.
-
-![flagger-grafana](https://raw.githubusercontent.com/stefanprodan/flagger/master/docs/screens/grafana-canary-analysis.png)
-
-## Prerequisites
-
-* Kubernetes >= 1.11
-* Istio >= 1.0
-* Prometheus >= 2.6
-
-## Installing the Chart
-
-Add Flagger Helm repository:
-
-```console
-helm repo add flagger https://flagger.app
-```
-
-To install the chart with the release name `flagger-grafana`:
-
-```console
-helm upgrade -i flagger-grafana flagger/grafana \
---namespace=istio-system \
---set url=http://prometheus:9090 \
---set user=admin \
---set password=admin
-```
-
-The command deploys Grafana on the Kubernetes cluster in the default namespace.
-The [configuration](#configuration) section lists the parameters that can be configured during installation.
-
-## Uninstalling the Chart
-
-To uninstall/delete the `flagger-grafana` deployment:
-
-```console
-helm delete --purge flagger-grafana
-```
-
-The command removes all the Kubernetes components associated with the chart and deletes the release.
-
-## Configuration
-
-The following tables lists the configurable parameters of the Grafana chart and their default values.
-
-Parameter | Description | Default
---- | --- | ---
-`image.repository` | Image repository | `grafana/grafana`
-`image.pullPolicy` | Image pull policy | `IfNotPresent`
-`image.tag` | Image tag | `<VERSION>`
-`replicaCount` | desired number of pods | `1`
-`resources` | pod resources | `none`
-`tolerations` | List of node taints to tolerate | `[]`
-`affinity` | node/pod affinities | `node`
-`nodeSelector` | node labels for pod assignment | `{}`
-`service.type` | type of service | `ClusterIP`
-`url` | Prometheus URL, used when Weave Cloud token is empty | `http://prometheus:9090`
-`token` | Weave Cloud token | `none`
-`user` | Grafana admin username | `admin`
-`password` | Grafana admin password | `admin`
-
-Specify each parameter using the `--set key=value[,key=value]` argument to `helm install`. For example,
-
-```console
-helm install flagger/grafana --name flagger-grafana \
---set token=WEAVE-CLOUD-TOKEN
-```
-
-Alternatively, a YAML file that specifies the values for the above parameters can be provided while installing the chart. For example,
-
-```console
-helm install flagger/grafana --name flagger-grafana -f values.yaml
-```
-
-> **Tip**: You can use the default [values.yaml](values.yaml)

-# Flagger load testing service
-
-[Flagger's](https://github.com/stefanprodan/flagger) load testing service is based on 
-[rakyll/hey](https://github.com/rakyll/hey) 
-and can be used to generates traffic during canary analysis when configured as a webhook.
-
-## Prerequisites
-
-* Kubernetes >= 1.11
-* Istio >= 1.0
-
-## Installing the Chart
-
-Add Flagger Helm repository:
-
-```console
-helm repo add flagger https://flagger.app
-```
-
-To install the chart with the release name `flagger-loadtester`:
-
-```console
-helm upgrade -i flagger-loadtester flagger/loadtester
-```
-
-The command deploys Grafana on the Kubernetes cluster in the default namespace.
-
-> **Tip**: Note that the namespace where you deploy the load tester should have the Istio sidecar injection enabled
-
-The [configuration](#configuration) section lists the parameters that can be configured during installation.
-
-## Uninstalling the Chart
-
-To uninstall/delete the `flagger-loadtester` deployment:
-
-```console
-helm delete --purge flagger-loadtester
-```
-
-The command removes all the Kubernetes components associated with the chart and deletes the release.
-
-## Configuration
-
-The following tables lists the configurable parameters of the load tester chart and their default values.
-
-Parameter | Description | Default
---- | --- | ---
-`image.repository` | Image repository | `quay.io/stefanprodan/flagger-loadtester`
-`image.pullPolicy` | Image pull policy | `IfNotPresent`
-`image.tag` | Image tag | `<VERSION>`
-`replicaCount` | desired number of pods | `1`
-`resources.requests.cpu` | CPU requests | `10m`
-`resources.requests.memory` | memory requests | `64Mi`
-`tolerations` | List of node taints to tolerate | `[]`
-`affinity` | node/pod affinities | `node`
-`nodeSelector` | node labels for pod assignment | `{}`
-`service.type` | type of service | `ClusterIP`
-`service.port` | ClusterIP port | `80`
-`cmd.logOutput` | Log the command output to stderr | `true`
-`cmd.timeout` | Command execution timeout | `1h`
-`logLevel` | Log level can be debug, info, warning, error or panic | `info`
-
-Specify each parameter using the `--set key=value[,key=value]` argument to `helm install`. For example,
-
-```console
-helm install flagger/loadtester --name flagger-loadtester \
---set cmd.logOutput=false
-```
-
-Alternatively, a YAML file that specifies the values for the above parameters can be provided while installing the chart. For example,
-
-```console
-helm install flagger/loadtester --name flagger-loadtester -f values.yaml
-```
-
-> **Tip**: You can use the default [values.yaml](values.yaml)

-# Contributor Covenant Code of Conduct
-
-## Our Pledge
-
-In the interest of fostering an open and welcoming environment, we as
-contributors and maintainers pledge to making participation in our project and
-our community a harassment-free experience for everyone, regardless of age, body
-size, disability, ethnicity, gender identity and expression, level of experience,
-education, socio-economic status, nationality, personal appearance, race,
-religion, or sexual identity and orientation.
-
-## Our Standards
-
-Examples of behavior that contributes to creating a positive environment
-include:
-
-* Using welcoming and inclusive language
-* Being respectful of differing viewpoints and experiences
-* Gracefully accepting constructive criticism
-* Focusing on what is best for the community
-* Showing empathy towards other community members
-
-Examples of unacceptable behavior by participants include:
-
-* The use of sexualized language or imagery and unwelcome sexual attention or
-  advances
-* Trolling, insulting/derogatory comments, and personal or political attacks
-* Public or private harassment
-* Publishing others' private information, such as a physical or electronic
-  address, without explicit permission
-* Other conduct which could reasonably be considered inappropriate in a
-  professional setting
-
-## Our Responsibilities
-
-Project maintainers are responsible for clarifying the standards of acceptable
-behavior and are expected to take appropriate and fair corrective action in
-response to any instances of unacceptable behavior.
-
-Project maintainers have the right and responsibility to remove, edit, or
-reject comments, commits, code, wiki edits, issues, and other contributions
-that are not aligned to this Code of Conduct, or to ban temporarily or
-permanently any contributor for other behaviors that they deem inappropriate,
-threatening, offensive, or harmful.
-
-## Scope
-
-This Code of Conduct applies both within project spaces and in public spaces
-when an individual is representing the project or its community. Examples of
-representing a project or community include using an official project e-mail
-address, posting via an official social media account, or acting as an appointed
-representative at an online or offline event. Representation of a project may be
-further defined and clarified by project maintainers.
-
-## Enforcement
-
-Instances of abusive, harassing, or otherwise unacceptable behavior
-may be reported by contacting stefan.prodan(at)gmail.com. 
-All complaints will be reviewed and investigated and will result in a response that is deemed
-necessary and appropriate to the circumstances. The project team is
-obligated to maintain confidentiality with regard to the reporter of
-an incident. Further details of specific enforcement policies may be
-posted separately.
-
-Project maintainers who do not follow or enforce the Code of Conduct in good
-faith may face temporary or permanent repercussions as determined by other
-members of the project's leadership.
-
-## Attribution
-
-This Code of Conduct is adapted from the [Contributor Covenant](https://www.contributor-covenant.org), version 1.4,
-available at https://www.contributor-covenant.org/version/1/4/code-of-conduct.html

+## Progressive Delivery
+
+Flagger was designed to give developers confidence in automating production releases with progressive delivery techniques. 
+
+::: tip Canary release
+
+A benefit of using canary releases is the ability to do capacity testing of the new version in a production environment
+with a safe rollback strategy if issues are found. By slowly ramping up the load, you can monitor and capture metrics
+about how the new version impacts the production environment.
+
+[Martin Fowler](https://martinfowler.com/bliki/CanaryRelease.html)

+## GitOps
+
+![GitOps with Flagger and Flux](/flagger-gitops.png)
+
+You can build fully automated GitOps pipelines for canary deployments with Flagger and
+[Flux](https://github.com/fluxcd/flux2).
+
+::: tip GitOps
+
+GitOps is a way to do Kubernetes cluster management and application delivery.
+It works by using Git as a single source of truth for declarative infrastructure and applications.
+With Git at the center of your delivery pipelines, developers can make pull requests
+to accelerate and simplify application deployments and operations tasks to Kubernetes.

----
-
-# Introduction
-
-[Flagger](https://github.com/stefanprodan/flagger) is a **Kubernetes** operator that automates the promotion of canary 
-deployments using **Istio** routing for traffic shifting and **Prometheus** metrics for canary analysis.
-The canary analysis can be extended with webhooks for running integration tests, 
-load tests or any other custom validation.
-
-Flagger implements a control loop that gradually shifts traffic to the canary while measuring key performance 
-indicators like HTTP requests success rate, requests average duration and pods health. 
-Based on the **KPIs** analysis a canary is promoted or aborted and the analysis result is published to **Slack**.
-
-![Flagger overview diagram](https://raw.githubusercontent.com/stefanprodan/flagger/master/docs/diagrams/flagger-canary-overview.png)
-
-Flagger can be configured with Kubernetes custom resources \(canaries.flagger.app kind\) and is compatible with 
-any CI/CD solutions made for Kubernetes. Since Flagger is declarative and reacts to Kubernetes events, 
-it can be used in **GitOps** pipelines together with Weave Flux or JenkinsX.
-
-This project is sponsored by [Weaveworks](https://www.weave.works/)

-# How it works
-
-[Flagger](https://github.com/stefanprodan/flagger) takes a Kubernetes deployment and optionally 
-a horizontal pod autoscaler \(HPA\) and creates a series of objects 
-\(Kubernetes deployments, ClusterIP services and Istio virtual services\) to drive the canary analysis and promotion. 
-
-![Flagger Canary Process](https://raw.githubusercontent.com/stefanprodan/flagger/master/docs/diagrams/flagger-canary-hpa.png)
-
-### Canary Custom Resource
-
-For a deployment named _podinfo_, a canary promotion can be defined using Flagger's custom resource:
-
-```yaml
-apiVersion: flagger.app/v1alpha3
-kind: Canary
-metadata:
-  name: podinfo
-  namespace: test
-spec:
-  # deployment reference
-  targetRef:
-    apiVersion: apps/v1
-    kind: Deployment
-    name: podinfo
-  # the maximum time in seconds for the canary deployment
-  # to make progress before it is rollback (default 600s)
-  progressDeadlineSeconds: 60
-  # HPA reference (optional)
-  autoscalerRef:
-    apiVersion: autoscaling/v2beta1
-    kind: HorizontalPodAutoscaler
-    name: podinfo
-  service:
-    # container port
-    port: 9898
-    # Istio gateways (optional)
-    gateways:
-    - public-gateway.istio-system.svc.cluster.local
-    # Istio virtual service host names (optional)
-    hosts:
-    - podinfo.example.com
-  canaryAnalysis:
-    # schedule interval (default 60s)
-    interval: 1m
-    # max number of failed metric checks before rollback
-    threshold: 10
-    # max traffic percentage routed to canary
-    # percentage (0-100)
-    maxWeight: 50
-    # canary increment step
-    # percentage (0-100)
-    stepWeight: 5
-    # Istio Prometheus checks
-    metrics:
-    - name: istio_requests_total
-      # minimum req success rate (non 5xx responses)
-      # percentage (0-100)
-      threshold: 99
-      interval: 1m
-    - name: istio_request_duration_seconds_bucket
-      # maximum req duration P99
-      # milliseconds
-      threshold: 500
-      interval: 30s
-    # external checks (optional)
-    webhooks:
-      - name: integration-tests
-        url: http://podinfo.test:9898/echo
-        timeout: 1m
-        # key-value pairs (optional)
-        metadata:
-          test: "all"
-          token: "16688eb5e9f289f1991c"
-```
-
-**Note** that the target deployment must have a single label selector in the format `app: <DEPLOYMENT-NAME>`:
-
-```yaml
-apiVersion: apps/v1
-kind: Deployment
-metadata:
-  name: podinfo
-spec:
-  selector:
-    matchLabels:
-      app: podinfo
-  template:
-    metadata:
-      labels:
-        app: podinfo
-```
-
-The target deployment should expose a TCP port that will be used by Flagger to create the ClusterIP Service and 
-the Istio Virtual Service. The container port from the target deployment should match the `service.port` value.
-
-### Canary Deployment
-
-![Flagger Canary Stages](https://raw.githubusercontent.com/stefanprodan/flagger/master/docs/diagrams/flagger-canary-steps.png)
-
-A canary deployment is triggered by changes in any of the following objects:
-
-* Deployment PodSpec (container image, command, ports, env, resources, etc)
-* ConfigMaps mounted as volumes or mapped to environment variables
-* Secrets mounted as volumes or mapped to environment variables
-
-Gated canary promotion stages:
-
-* scan for canary deployments
-* check Istio virtual service routes are mapped to primary and canary ClusterIP services
-* check primary and canary deployments status
-    * halt advancement if a rolling update is underway
-    * halt advancement if pods are unhealthy
-* increase canary traffic weight percentage from 0% to 5% (step weight)
-* call webhooks and check results
-* check canary HTTP request success rate and latency
-    * halt advancement if any metric is under the specified threshold
-    * increment the failed checks counter
-* check if the number of failed checks reached the threshold
-    * route all traffic to primary
-    * scale to zero the canary deployment and mark it as failed
-    * wait for the canary deployment to be updated and start over
-* increase canary traffic weight by 5% (step weight) till it reaches 50% (max weight) 
-    * halt advancement while canary request success rate is under the threshold
-    * halt advancement while canary request duration P99 is over the threshold
-    * halt advancement if the primary or canary deployment becomes unhealthy 
-    * halt advancement while canary deployment is being scaled up/down by HPA
-* promote canary to primary
-    * copy ConfigMaps and Secrets from canary to primary
-    * copy canary deployment spec template over primary
-* wait for primary rolling update to finish
-    * halt advancement if pods are unhealthy
-* route all traffic to primary
-* scale to zero the canary deployment
-* mark rollout as finished
-* wait for the canary deployment to be updated and start over
-
-### Canary Analysis
-
-The canary analysis runs periodically until it reaches the maximum traffic weight or the failed checks threshold. 
-
-Spec:
-
-```yaml
-  canaryAnalysis:
-    # schedule interval (default 60s)
-    interval: 1m
-    # max number of failed metric checks before rollback
-    threshold: 10
-    # max traffic percentage routed to canary
-    # percentage (0-100)
-    maxWeight: 50
-    # canary increment step
-    # percentage (0-100)
-    stepWeight: 2
-```
-
-The above analysis, if it succeeds, will run for 25 minutes while validating the HTTP metrics and webhooks every minute.
-You can determine the minimum time that it takes to validate and promote a canary deployment using this formula:
-
-```
-interval * (maxWeight / stepWeight)
-```
-
-And the time it takes for a canary to be rollback when the metrics or webhook checks are failing:
-
-```
-interval * threshold 
-```
-
-### HTTP Metrics
-
-The canary analysis is using the following Prometheus queries:
-
-**HTTP requests success rate percentage**
-
-Spec:
-
-```yaml
-  canaryAnalysis:
-    metrics:
-    - name: istio_requests_total
-      # minimum req success rate (non 5xx responses)
-      # percentage (0-100)
-      threshold: 99
-      interval: 1m
-```
-
-Query:
-
-```javascript
-sum(
-    rate(
-        istio_requests_total{
-          reporter="destination",
-          destination_workload_namespace=~"$namespace",
-          destination_workload=~"$workload",
-          response_code!~"5.*"
-        }[$interval]
-    )
-) 
-/ 
-sum(
-    rate(
-        istio_requests_total{
-          reporter="destination",
-          destination_workload_namespace=~"$namespace",
-          destination_workload=~"$workload"
-        }[$interval]
-    )
-)
-```
-
-**HTTP requests milliseconds duration P99**
-
-Spec:
-
-```yaml
-  canaryAnalysis:
-    metrics:
-    - name: istio_request_duration_seconds_bucket
-      # maximum req duration P99
-      # milliseconds
-      threshold: 500
-      interval: 1m
-```
-
-Query:
-
-```javascript
-histogram_quantile(0.99, 
-  sum(
-    irate(
-      istio_request_duration_seconds_bucket{
-        reporter="destination",
-        destination_workload=~"$workload",
-        destination_workload_namespace=~"$namespace"
-      }[$interval]
-    )
-  ) by (le)
-)
-```
-
-> **Note** that the metric interval should be lower or equal to the control loop interval.
-
-### Webhooks
-
-The canary analysis can be extended with webhooks. 
-Flagger will call each webhook URL and determine from the response status code (HTTP 2xx) if the canary is failing or not.
-
-Spec:
-
-```yaml
-  canaryAnalysis:
-    webhooks:
-      - name: integration-tests
-        url: http://podinfo.test:9898/echo
-        timeout: 30s
-        metadata:
-          test: "all"
-          token: "16688eb5e9f289f1991c"
-      - name: load-tests
-        url: http://podinfo.test:9898/echo
-        timeout: 30s
-        metadata:
-          key1: "val1"
-          key2: "val2"
-```
-
-> **Note** that the sum of all webhooks timeouts should be lower than the control loop interval. 
-
-Webhook payload (HTTP POST):
-
-```json
-{
-    "name": "podinfo",
-    "namespace": "test", 
-    "metadata": {
-        "test":  "all",
-        "token":  "16688eb5e9f289f1991c"
-    }
-}
-```
-
-Response status codes:
-
-* 200-202 - advance canary by increasing the traffic weight
-* timeout or non-2xx - halt advancement and increment failed checks
-
-On a non-2xx response Flagger will include the response body (if any) in the failed checks log and Kubernetes events.
-
-### Load Testing
-
-For workloads that are not receiving constant traffic Flagger can be configured with a webhook, 
-that when called, will start a load test for the target workload.
-If the target workload doesn't receive any traffic during the canary analysis, 
-Flagger metric checks will fail with "no values found for metric istio_requests_total".
-
-Flagger comes with a load testing service based on [rakyll/hey](https://github.com/rakyll/hey) 
-that generates traffic during analysis when configured as a webhook.
-
-![Flagger Load Testing Webhook](https://raw.githubusercontent.com/stefanprodan/flagger/master/docs/diagrams/flagger-load-testing.png)
-
-First you need to deploy the load test runner in a namespace with Istio sidecar injection enabled:
-
-```bash
-export REPO=https://raw.githubusercontent.com/stefanprodan/flagger/master
-
-kubectl -n test apply -f ${REPO}/artifacts/loadtester/deployment.yaml
-kubectl -n test apply -f ${REPO}/artifacts/loadtester/service.yaml
-```
-
-Or by using Helm:
-
-```bash
-helm repo add flagger https://flagger.app
-
-helm upgrade -i flagger-loadtester flagger/loadtester \
---namepace=test \
---set cmd.logOutput=true \
---set cmd.timeout=1h
-```
-
-When deployed the load tester API will be available at `http://flagger-loadtester.test/`. 
-
-Now you can add webhooks to the canary analysis spec:
-
-```yaml
-webhooks:
-  - name: load-test-get
-    url: http://flagger-loadtester.test/
-    timeout: 5s
-    metadata:
-      cmd: "hey -z 1m -q 10 -c 2 http://podinfo.test:9898/"
-  - name: load-test-post
-    url: http://flagger-loadtester.test/
-    timeout: 5s
-    metadata:
-      cmd: "hey -z 1m -q 10 -c 2 -m POST -d '{test: 2}' http://podinfo.test:9898/echo"
-```
-
-When the canary analysis starts, Flagger will call the webhooks and the load tester will run the `hey` commands 
-in the background, if they are not already running. This will ensure that during the 
-analysis, the `podinfo.test` virtual service will receive a steady steam of GET and POST requests.
-
-If your workload is exposed outside the mesh with the Istio Gateway and TLS you can point `hey` to the 
-public URL and use HTTP2.
-
-```yaml
-webhooks:
-  - name: load-test-get
-    url: http://flagger-loadtester.test/
-    timeout: 5s
-    metadata:
-      cmd: "hey -z 1m -q 10 -c 2 -h2 https://podinfo.example.com/"
-```
-
-The load tester can run arbitrary commands as long as the binary is present in the container image.
-For example if you you want to replace `hey` with another CLI, you can create your own Docker image:
-
-```dockerfile
-FROM quay.io/stefanprodan/flagger-loadtester:<VER>
-
-RUN curl -Lo /usr/local/bin/my-cli https://github.com/user/repo/releases/download/ver/my-cli \
-    && chmod +x /usr/local/bin/my-cli
-```

-
-Install the `kubectl` command-line tool:
-
-```text
-gcloud components install kubectl
-```
-
-Install the `helm` command-line tool:
-
-```text
-brew install kubernetes-helm
-```
-
-### GKE cluster setup
-
-Create a cluster with three nodes using the latest Kubernetes version:
-
-```bash
-k8s_version=$(gcloud container get-server-config --format=json \
-| jq -r '.validNodeVersions[0]')
-
-gcloud container clusters create istio \
---cluster-version=${k8s_version} \
---zone=europe-west3-a \
---num-nodes=3 \
---machine-type=n1-highcpu-4 \
---preemptible \
---no-enable-cloud-logging \
---disk-size=30 \
---enable-autorepair \
---scopes=gke-default,compute-rw,storage-rw
-```
-
-The above command will create a default node pool consisting of `n1-highcpu-4` \(vCPU: 4, RAM 3.60GB, DISK: 30GB\) 
-preemptible VMs. Preemptible VMs are up to 80% cheaper than regular instances and are terminated and replaced 
-after a maximum of 24 hours.
-
-Set up credentials for `kubectl`:
-
-```bash
-gcloud container clusters get-credentials istio -z=europe-west3-a
-```
-
-Create a cluster admin role binding:
-
-```bash
-kubectl create clusterrolebinding "cluster-admin-$(whoami)" \
---clusterrole=cluster-admin \
---user="$(gcloud config get-value core/account)"
-```
-
-Validate your setup with:
-
-```bash
-kubectl get nodes -o wide
-```
-
-### Cloud DNS setup
-
-You will need an internet domain and access to the registrar to change the name servers to Google Cloud DNS.
-
-Create a managed zone named `istio` in Cloud DNS \(replace `example.com` with your domain\):
-
-```bash
-gcloud dns managed-zones create \
---dns-name="example.com." \
---description="Istio zone" "istio"
-```
-
-Look up your zone's name servers:
-
-```bash
-gcloud dns managed-zones describe istio
-```
-
-Update your registrar's name server records with the records returned by the above command.
-
-Wait for the name servers to change \(replace `example.com` with your domain\):
-
-```bash
-watch dig +short NS example.com
-```
-
-Create a static IP address named `istio-gateway-ip` in the same region as your GKE cluster:
-
-```bash
-gcloud compute addresses create istio-gateway-ip --region europe-west3
-```
-
-Find the static IP address:
-
-```bash
-gcloud compute addresses describe istio-gateway-ip --region europe-west3
-```
-
-Create the following DNS records \(replace `example.com` with your domain and set your Istio Gateway IP\):
-
-```bash
-DOMAIN="example.com"
-GATEWAYIP="35.198.98.90"
-
-gcloud dns record-sets transaction start --zone=istio
-
-gcloud dns record-sets transaction add --zone=istio \
---name="${DOMAIN}" --ttl=300 --type=A ${GATEWAYIP}
-
-gcloud dns record-sets transaction add --zone=istio \
---name="www.${DOMAIN}" --ttl=300 --type=A ${GATEWAYIP}
-
-gcloud dns record-sets transaction add --zone=istio \
---name="*.${DOMAIN}" --ttl=300 --type=A ${GATEWAYIP}
-
-gcloud dns record-sets transaction execute --zone istio
-```
-
-Verify that the wildcard DNS is working \(replace `example.com` with your domain\):
-
-```bash
-watch host test.example.com
-```
-
-### Install Istio with Helm
-
-Download the latest Istio release:
-
-```bash
-curl -L https://git.io/getLatestIstio | sh -
-```
-
-Navigate to `istio-x.x.x` dir and copy the Istio CLI in your bin:
-
-```bash
-cd istio-x.x.x/
-sudo cp ./bin/istioctl /usr/local/bin/istioctl
-```
-
-Apply the Istio CRDs:
-
-```bash
-kubectl apply -f ./install/kubernetes/helm/istio/templates/crds.yaml
-```
-
-Create a service account and a cluster role binding for Tiller:
-
-```bash
-kubectl apply -f ./install/kubernetes/helm/helm-service-account.yaml
-```
-
-Deploy Tiller in the `kube-system` namespace:
-
-```bash
-helm init --service-account tiller
-```
-
-Find the GKE IP ranges:
-
-```bash
-gcloud container clusters describe istio --zone=europe-west3-a \
-| grep -e clusterIpv4Cidr -e servicesIpv4Cidr
-```
-
-You'll be using the IP ranges to allow unrestricted egress traffic for services running inside the service mesh.
-
-Configure Istio with Prometheus, Jaeger, and cert-manager:
-
-```yaml
-global:
-  nodePort: false
-  proxy:
-    # replace with your GKE IP ranges
-    includeIPRanges: "10.28.0.0/14,10.7.240.0/20"

-
-Save the above file as `my-istio.yaml` and install Istio with Helm:
-
-```bash
-helm upgrade --install istio ./install/kubernetes/helm/istio \
---namespace=istio-system \
--f ./my-istio.yaml
-```
-
-Verify that Istio workloads are running:
-
-```text
-kubectl -n istio-system get pods
-```
-
-### Configure Istio Gateway with LE TLS
-
-![Istio Let's Encrypt diagram](https://raw.githubusercontent.com/stefanprodan/istio-gke/master/docs/screens/istio-cert-manager-gcp.png)
-
-Create a Istio Gateway in istio-system namespace with HTTPS redirect:
-
-```yaml
-apiVersion: networking.istio.io/v1alpha3
-kind: Gateway
-metadata:
-  name: public-gateway
-  namespace: istio-system
-spec:
-  selector:
-    istio: ingressgateway
-  servers:
-  - port:
-      number: 80
-      name: http

-    hosts:
-    - "*"
-    tls:
-      mode: SIMPLE
-      privateKey: /etc/istio/ingressgateway-certs/tls.key
-      serverCertificate: /etc/istio/ingressgateway-certs/tls.crt
-```
-
-Save the above resource as istio-gateway.yaml and then apply it:
-
-```text
-kubectl apply -f ./istio-gateway.yaml
-```
-
-Create a service account with Cloud DNS admin role \(replace `my-gcp-project` with your project ID\):
-
-```bash
-GCP_PROJECT=my-gcp-project
-
-gcloud iam service-accounts create dns-admin \
---display-name=dns-admin \
---project=${GCP_PROJECT}
-
-gcloud iam service-accounts keys create ./gcp-dns-admin.json \
---iam-account=dns-admin@${GCP_PROJECT}.iam.gserviceaccount.com \
---project=${GCP_PROJECT}
-
-gcloud projects add-iam-policy-binding ${GCP_PROJECT} \
---member=serviceAccount:dns-admin@${GCP_PROJECT}.iam.gserviceaccount.com \
---role=roles/dns.admin
-```
-
-Create a Kubernetes secret with the GCP Cloud DNS admin key:
-
-```bash
-kubectl create secret generic cert-manager-credentials \
---from-file=./gcp-dns-admin.json \
---namespace=istio-system
-```
-
-Create a letsencrypt issuer for CloudDNS \(replace `email@example.com` with a valid email address and 
-`my-gcp-project`with your project ID\):
-
-```yaml
-apiVersion: certmanager.k8s.io/v1alpha1
-kind: Issuer
-metadata:
-  name: letsencrypt-prod
-  namespace: istio-system
-spec:
-  acme:
-    server: https://acme-v02.api.letsencrypt.org/directory
-    email: email@example.com
-    privateKeySecretRef:
-      name: letsencrypt-prod
-    dns01:
-      providers:
-      - name: cloud-dns
-        clouddns:
-          serviceAccountSecretRef:
-            name: cert-manager-credentials
-            key: gcp-dns-admin.json
-          project: my-gcp-project
-```
-
-Save the above resource as letsencrypt-issuer.yaml and then apply it:
-
-```text
-kubectl apply -f ./letsencrypt-issuer.yaml
-```
-
-Create a wildcard certificate \(replace `example.com` with your domain\):
-
-```yaml
-apiVersion: certmanager.k8s.io/v1alpha1
-kind: Certificate
-metadata:
-  name: istio-gateway
-  namespace: istio-system
-spec:
-  secretname: istio-ingressgateway-certs
-  issuerRef:
-    name: letsencrypt-prod
-  commonName: "*.example.com"
-  acme:
-    config:
-    - dns01:
-        provider: cloud-dns
-      domains:
-      - "*.example.com"
-      - "example.com"
-```
-
-Save the above resource as of-cert.yaml and then apply it:
-
-```text
-kubectl apply -f ./of-cert.yaml
-```
-
-In a couple of seconds cert-manager should fetch a wildcard certificate from letsencrypt.org:
-
-```text
-kubectl -n istio-system logs deployment/certmanager -f
-
-Certificate issued successfully
-Certificate istio-system/istio-gateway scheduled for renewal in 1438 hours
-```
-
-Recreate Istio ingress gateway pods:
-
-```bash
-kubectl -n istio-system delete pods -l istio=ingressgateway
-```
-
-Note that Istio gateway doesn't reload the certificates from the TLS secret on cert-manager renewal. 
-Since the GKE cluster is made out of preemptible VMs the gateway pods will be replaced once every 24h, 
-if your not using preemptible nodes then you need to manually kill the gateway pods every two months 
-before the certificate expires.
-
-### Expose services outside the service mesh
-
-In order to expose services via the Istio Gateway you have to create a Virtual Service attached to Istio Gateway.
-
-Create a virtual service in `istio-system` namespace for Grafana \(replace `example.com` with your domain\):
-
-```yaml
-apiVersion: networking.istio.io/v1alpha3
-kind: VirtualService
-metadata:
-  name: grafana
-  namespace: istio-system
-spec:
-  hosts:
-  - "grafana.example.com"
-  gateways:
-  - public-gateway.istio-system.svc.cluster.local
-  http:
-  - route:
-    - destination:
-        host: grafana
-    timeout: 30s
-```
-
-Save the above resource as grafana-virtual-service.yaml and then apply it:
-
-```bash
-kubectl apply -f ./grafana-virtual-service.yaml
-```
-
-Navigate to `http://grafana.example.com` in your browser and you should be redirected to the HTTPS version.
-
-Check that HTTP2 is enabled:
-
-```bash
-curl -I --http2 https://grafana.example.com
-
-HTTP/2 200 
-content-type: text/html; charset=UTF-8
-x-envoy-upstream-service-time: 3
-server: envoy

-# Alerting
-
-### Slack
-
-Flagger can be configured to send Slack notifications:
-
-```bash
-helm upgrade -i flagger flagger/flagger \
---namespace=istio-system \
---set slack.url=https://hooks.slack.com/services/YOUR/SLACK/WEBHOOK \
---set slack.channel=general \
---set slack.user=flagger
-```
-
-Once configured with a Slack incoming **webhook**, Flagger will post messages when a canary deployment 
-has been initialised, when a new revision has been detected and if the canary analysis failed or succeeded.
-
-![flagger-slack](https://raw.githubusercontent.com/stefanprodan/flagger/master/docs/screens/slack-canary-notifications.png)
-
-A canary deployment will be rolled back if the progress deadline exceeded or if the analysis reached the 
-maximum number of failed checks:
-
-![flagger-slack-errors](https://raw.githubusercontent.com/stefanprodan/flagger/master/docs/screens/slack-canary-failed.png)
-
-### Prometheus Alert Manager
-
-Besides Slack, you can use Alertmanager to trigger alerts when a canary deployment failed:
-
-```yaml
-  - alert: canary_rollback
-    expr: flagger_canary_status > 1
-    for: 1m

-# Monitoring
-
-### Grafana
-
-Flagger comes with a Grafana dashboard made for canary analysis. Install Grafana with Helm:
-
-```bash
-helm upgrade -i flagger-grafana flagger/grafana \
---namespace=istio-system \
---set url=http://prometheus:9090 \
---set user=admin \
---set password=admin
-```
-
-The dashboard shows the RED and USE metrics for the primary and canary workloads:
-
-![canary dashboard](https://raw.githubusercontent.com/stefanprodan/flagger/master/docs/screens/grafana-canary-analysis.png)
-
-### Logging
-
-The canary errors and latency spikes have been recorded as Kubernetes events and logged by Flagger in json format:
-
-```text
-kubectl -n istio-system logs deployment/flagger --tail=100 | jq .msg
-
-Starting canary deployment for podinfo.test
-Advance podinfo.test canary weight 5
-Advance podinfo.test canary weight 10
-Advance podinfo.test canary weight 15
-Advance podinfo.test canary weight 20
-Advance podinfo.test canary weight 25
-Advance podinfo.test canary weight 30
-Advance podinfo.test canary weight 35
-Halt podinfo.test advancement success rate 98.69% < 99%
-Advance podinfo.test canary weight 40

-Advance podinfo.test canary weight 50
-Copying podinfo.test template spec to podinfo-primary.test
-Halt podinfo-primary.test advancement waiting for rollout to finish: 1 old replicas are pending termination
-Scaling down podinfo.test
-Promotion completed! podinfo.test
-```
-
-### Metrics
-
-Flagger exposes Prometheus metrics that can be used to determine the canary analysis status and 
-the destination weight values:
-
-```bash
-# Canaries total gauge
-flagger_canary_total{namespace="test"} 1
-
-# Canary promotion last known status gauge
-# 0 - running, 1 - successful, 2 - failed
-flagger_canary_status{name="podinfo" namespace="test"} 1
-
-# Canary traffic weight gauge
-flagger_canary_weight{workload="podinfo-primary" namespace="test"} 95
-flagger_canary_weight{workload="podinfo" namespace="test"} 5
-
-# Seconds spent performing canary analysis histogram
-flagger_canary_duration_seconds_bucket{name="podinfo",namespace="test",le="10"} 6
-flagger_canary_duration_seconds_bucket{name="podinfo",namespace="test",le="+Inf"} 6

-# Canary Deployments
-
-This guide shows you how to use Istio and Flagger to automate canary deployments.
-
-Create a test namespace with Istio sidecar injection enabled:
-
-```bash
-export REPO=https://raw.githubusercontent.com/stefanprodan/flagger/master
-
-kubectl apply -f ${REPO}/artifacts/namespaces/test.yaml
-```
-
-Create a deployment and a horizontal pod autoscaler:
-
-```bash
-kubectl apply -f ${REPO}/artifacts/canaries/deployment.yaml
-kubectl apply -f ${REPO}/artifacts/canaries/hpa.yaml
-```
-
-Deploy the load testing service to generate traffic during the canary analysis:
-
-```bash
-kubectl -n test apply -f ${REPO}/artifacts/loadtester/deployment.yaml
-kubectl -n test apply -f ${REPO}/artifacts/loadtester/service.yaml
-```
-
-Create a canary custom resource (replace example.com with your own domain):
-
-```yaml
-apiVersion: flagger.app/v1alpha3
-kind: Canary
-metadata:
-  name: podinfo
-  namespace: test
-spec:
-  # deployment reference
-  targetRef:
-    apiVersion: apps/v1

-      # maximum req duration P99
-      # milliseconds
-      threshold: 500
-      interval: 30s
-    # generate traffic during analysis
-    webhooks:
-      - name: load-test
-        url: http://flagger-loadtester.test/
-        timeout: 5s
-        metadata:
-          cmd: "hey -z 1m -q 10 -c 2 http://podinfo.test:9898/"
-```
-
-Save the above resource as podinfo-canary.yaml and then apply it:
-
-```bash
-kubectl apply -f ./podinfo-canary.yaml
-```
-
-After a couple of seconds Flagger will create the canary objects:
-
-```bash
-# applied 
-deployment.apps/podinfo
-horizontalpodautoscaler.autoscaling/podinfo
-canary.flagger.app/podinfo
-
-# generated 
-deployment.apps/podinfo-primary
-horizontalpodautoscaler.autoscaling/podinfo-primary
-service/podinfo
-service/podinfo-canary
-service/podinfo-primary
-virtualservice.networking.istio.io/podinfo
-```
-
-Trigger a canary deployment by updating the container image:
-
-```bash
-kubectl -n test set image deployment/podinfo \
-podinfod=quay.io/stefanprodan/podinfo:1.4.0
-```
-
-Flagger detects that the deployment revision changed and starts a new rollout:
-
-```text
-kubectl -n test describe canary/podinfo
-
-Status:
-  Canary Weight:         0
-  Failed Checks:         0

-```
-
-**Note** that if you apply new changes to the deployment during the canary analysis, Flagger will restart the analysis.
-
-You can monitor all canaries with:
-
-```bash
-watch kubectl get canaries --all-namespaces
-
-NAMESPACE   NAME      STATUS        WEIGHT   LASTTRANSITIONTIME
-test        podinfo   Progressing   15       2019-01-16T14:05:07Z

-prod        backend   Failed        0        2019-01-14T17:05:07Z
-```
-
-During the canary analysis you can generate HTTP 500 errors and high latency to test if Flagger pauses the rollout.
-
-Create a tester pod and exec into it:
-
-```bash
-kubectl -n test run tester \
---image=quay.io/stefanprodan/podinfo:1.2.1 \
--- ./podinfo --port=9898
-
-kubectl -n test exec -it tester-xx-xx sh
-```
-
-Generate HTTP 500 errors:
-
-```bash
-watch curl http://podinfo-canary:9898/status/500
-```
-
-Generate latency:
-
-```bash
-watch curl http://podinfo-canary:9898/delay/1
-```
-
-When the number of failed checks reaches the canary analysis threshold, the traffic is routed back to the primary, 
-the canary is scaled to zero and the rollout is marked as failed.
