+# 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)

+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed

+          do not modify the License. You may add Your own attribution
+          notices within Derivative Works that You distribute, alongside
+          or as an addendum to the NOTICE text from the Work, provided
+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and
+      may provide additional or different license terms and conditions

+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.

+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade

+   7. Disclaimer of Warranty. Unless required by applicable law or
+      agreed to in writing, Licensor provides the Work (and each
+      Contributor provides its Contributions) on an "AS IS" BASIS,
+      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or

+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+
+   8. Limitation of Liability. In no event and under no legal theory,
+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a

+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,

+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.

-Continuous delivery is accepted as an enterprise software practice, and is a natural evolution of well-established
-continuous integration principles. However continuous deployment continues to be notably rare,
-perhaps due to the complexity of management and the fear of failed deployments impacting system availability.

-Flagger is an open source Kubernetes operator that aims to untangle this complexity.
-It automates the promotion of canary deployments by using 
-Istio, Linkerd, App Mesh, Gloo or NGNIX traffic shifting and Prometheus metrics to analyse the application's behaviour during a controlled rollout. 
-The canary analysis can be extended with webhooks for running integration tests, load tests or any other custom validation.
+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 or MS Teams.
+### Install 

-Flagger can automate the application analysis for the following deployment strategies:
+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).

-* Canary (progressive traffic shifting)
-* A/B Testing (HTTP headers and cookies traffic routing)
-* Blue/Green (traffic switch)
+Deploy Flagger in the `istio-system` namespace using Helm:

-With Flagger you don't have to worry about keeping code and configuration changes in sync. 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.
+```bash
+# add the Helm repository
+helm repo add flagger https://flagger.app

-### Documentation
+# install or upgrade
+helm upgrade -i flagger flagger/flagger \
+--namespace=istio-system \
+--set metricsServer=http://prometheus.istio-system:9090 
+```

-Flagger documentation can be found at [docs.flagger.app](https://docs.flagger.app)

+### Usage

-This project is sponsored by [Weaveworks](https://www.weave.works/)
+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-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)
+* 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 (revision bump) 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 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 (revision bump) and start over
+
+You can change the canary analysis _max weight_ and the _step weight_ percentage in the Flagger's 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: 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
+```
+
+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

+  Normal   Synced  5s    flagger  Promotion completed! Scaling down podinfo.test
+```
+
+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:
+  Canary Weight:         0
+  Failed Checks:         10

+
+### 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
+Halt podinfo.test advancement request duration 1.515s > 500ms
+Advance podinfo.test canary weight 45
+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
+```
+
+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
+

+# 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
