+# Flagger install on Kubernetes with SuperGloo
+
+This guide walks you through setting up Flagger on a Kubernetes cluster using [SuperGloo](https://github.com/solo-io/supergloo).
+
+SuperGloo by [Solo.io](https://solo.io) is an opinionated abstraction layer that simplifies the installation, management, and operation of your service mesh.
+It supports running multiple ingresses with multiple meshes (Istio, App Mesh, Consul Connect and Linkerd 2) in the same cluster.
+
+### Prerequisites
+
+Flagger requires a Kubernetes cluster **v1.11** or newer with the following admission controllers enabled:
+
+* MutatingAdmissionWebhook
+* ValidatingAdmissionWebhook
+
+### Install Istio with SuperGloo
+
+#### Install SuperGloo command line interface helper
+
+SuperGloo includes a command line helper (CLI) that makes operation of SuperGloo easier.
+The CLI is not required for SuperGloo to function correctly.
+
+If you use [Homebrew](https://brew.sh) package manager run the following
+commands to install the SuperGloo CLI.
+
+```bash
+brew tap solo-io/tap
+brew solo-io/tap/supergloo
+```
+
+Or you can download SuperGloo CLI and add it to your path:
+
+```bash
+curl -sL https://run.solo.io/supergloo/install | sh
+export PATH=$HOME/.supergloo/bin:$PATH
+```
+
+#### Install SuperGloo controller
+
+Deploy the SuperGloo controller in the `supergloo-system` namespace:
+
+```bash
+supergloo init
+```
+
+This is equivalent to installing SuperGloo using its Helm chart
+
+```bash
+helm repo add supergloo http://storage.googleapis.com/supergloo-helm
+helm upgrade --install supergloo supergloo/supergloo --namespace supergloo-system
+```
+
+#### Install Istio using SuperGloo
+
+Create the `istio-system` namespace and install Istio with traffic management, telemetry and Prometheus enabled:
+
+```bash
+ISTIO_VER="1.0.6"
+
+kubectl create namespace istio-system
+
+supergloo install istio --name istio \
+--namespace=supergloo-system \
+--auto-inject=true \
+--installation-namespace=istio-system \
+--mtls=false \
+--prometheus=true \
+--version=${ISTIO_VER}
+```
+
+This creates a Kubernetes Custom Resource (CRD) like the following.
+
+```yaml
+apiVersion: supergloo.solo.io/v1
+kind: Install
+metadata:
+  name: istio
+  namespace: supergloo-system
+spec:
+  installationNamespace: istio-system
+  mesh:
+    installedMesh:
+      name: istio
+      namespace: supergloo-system
+    istioMesh:
+      enableAutoInject: true
+      enableMtls: false
+      installGrafana: false
+      installJaeger: false
+      installPrometheus: true
+      istioVersion: 1.0.6
+```
+
+#### Allow Flagger to manipulate SuperGloo
+
+Create a cluster role binding so that Flagger can manipulate SuperGloo custom resources:
+
+```bash
+kubectl create clusterrolebinding flagger-supergloo \
+--clusterrole=mesh-discovery \
+--serviceaccount=istio-system:flagger
+```
+
+Wait for the Istio control plane to become available:
+
+```bash
+kubectl --namespace istio-system rollout status deployment/istio-sidecar-injector
+kubectl --namespace istio-system rollout status deployment/prometheus
+```
+
+### Install Flagger
+
+Add Flagger Helm repository:
+
+```bash
+helm repo add flagger https://flagger.app
+```
+
+Deploy Flagger in the _**istio-system**_ namespace and set the service mesh provider to SuperGloo:
+
+```bash
+helm upgrade -i flagger flagger/flagger \
+--namespace=istio-system \
+--set metricsServer=http://prometheus.istio-system:9090 \
+--set meshProvider=supergloo:istio.supergloo-system
+```
+
+When using SuperGloo the mesh provider format is `supergloo:<MESH-NAME>.<SUPERGLOO-NAMESPACE>`.
+
+Optionally you can enable **Slack** notifications:
+
+```bash
+helm upgrade -i flagger flagger/flagger \
+--reuse-values \
+--namespace=istio-system \
+--set slack.url=https://hooks.slack.com/services/YOUR/SLACK/WEBHOOK \
+--set slack.channel=general \
+--set slack.user=flagger
+```
+
+### Install Grafana
+
+Flagger comes with a Grafana dashboard made for monitoring the canary analysis.
+
+Deploy Grafana in the _**istio-system**_ namespace:
+
+```bash
+helm upgrade -i flagger-grafana flagger/grafana \
+--namespace=istio-system \
+--set url=http://prometheus.istio-system:9090
+```
+
+You can access Grafana using port forwarding:
+
+```bash
+kubectl -n istio-system port-forward svc/flagger-grafana 3000:80
+```
+
+### Install Load Tester
+
+Flagger comes with an optional load testing service that generates traffic
+during canary analysis when configured as a webhook.
+
+Deploy the load test runner with Helm:
+
+```bash
+helm upgrade -i flagger-loadtester flagger/loadtester \
+--namespace=test \
+--set cmd.timeout=1h
+```
+
+Deploy with kubectl:
+
+```bash
+helm fetch --untar --untardir . flagger/loadtester &&
+helm template loadtester \
+--name flagger-loadtester \
+--namespace=test
+> $HOME/flagger-loadtester.yaml
+
+# apply
+kubectl apply -f $HOME/flagger-loadtester.yaml
+```
+
+> **Note** that the load tester should be deployed in a namespace with Istio sidecar injection enabled.

+# NGNIX Ingress Controller Canary Deployments
+
+This guide shows you how to use the NGINX ingress controller and Flagger to automate canary deployments and A/B testing.
+
+![Flagger NGINX Ingress Controller](https://raw.githubusercontent.com/weaveworks/flagger/master/docs/diagrams/flagger-nginx-overview.png)
+
+### Prerequisites
+
+Flagger requires a Kubernetes cluster **v1.11** or newer and NGINX ingress **0.24** or newer.
+
+Install NGINX with Helm:
+
+```bash
+helm upgrade -i nginx-ingress stable/nginx-ingress \
+--namespace ingress-nginx \
+--set controller.stats.enabled=true \
+--set controller.metrics.enabled=true \
+--set controller.podAnnotations."prometheus\.io/scrape"=true \
+--set controller.podAnnotations."prometheus\.io/port"=10254 
+```
+
+Install Flagger and the Prometheus add-on in the same namespace as NGINX:
+
+```bash
+helm repo add flagger https://flagger.app
+
+helm upgrade -i flagger flagger/flagger \
+--namespace ingress-nginx \
+--set prometheus.install=true \
+--set meshProvider=nginx
+```
+
+Optionally you can enable Slack notifications:
+
+```bash
+helm upgrade -i flagger flagger/flagger \
+--reuse-values \
+--namespace ingress-nginx \
+--set slack.url=https://hooks.slack.com/services/YOUR/SLACK/WEBHOOK \
+--set slack.channel=general \
+--set slack.user=flagger
+```
+
+### Bootstrap
+
+Flagger takes a Kubernetes deployment and optionally a horizontal pod autoscaler (HPA), 
+then creates a series of objects (Kubernetes deployments, ClusterIP services and canary ingress). 
+These objects expose the application outside the cluster and drive the canary analysis and promotion.
+
+Create a test namespace:
+
+```bash
+kubectl create ns test
+```
+
+Create a deployment and a horizontal pod autoscaler:
+
+```bash
+kubectl apply -f ${REPO}/artifacts/nginx/deployment.yaml
+kubectl apply -f ${REPO}/artifacts/nginx/hpa.yaml
+```
+
+Deploy the load testing service to generate traffic during the canary analysis:
+
+```bash
+helm upgrade -i flagger-loadtester flagger/loadtester \
+--namespace=test
+```
+
+Create an ingress definition (replace `app.example.com` with your own domain):
+
+```yaml
+apiVersion: extensions/v1beta1
+kind: Ingress
+metadata:
+  name: podinfo
+  namespace: test
+  labels:
+    app: podinfo
+  annotations:
+    kubernetes.io/ingress.class: "nginx"
+spec:
+  rules:
+    - host: app.example.com
+      http:
+        paths:
+          - backend:
+              serviceName: podinfo
+              servicePort: 9898
+```
+
+Save the above resource as podinfo-ingress.yaml and then apply it:
+
+```bash
+kubectl apply -f ./podinfo-ingress.yaml
+```
+
+Create a canary custom resource (replace `app.example.com` with your own domain):
+
+```yaml

+    # load testing (optional)
+    webhooks:
+      - name: load-test
+        url: http://flagger-loadtester.test/
+        timeout: 5s
+        metadata:
+          type: cmd
+          cmd: "hey -z 1m -q 10 -c 2 http://app.example.com/"
+```
+
+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
+ingresses.extensions/podinfo
+canary.flagger.app/podinfo

+horizontalpodautoscaler.autoscaling/podinfo-primary
+service/podinfo
+service/podinfo-canary
+service/podinfo-primary
+ingresses.extensions/podinfo-canary
+```
+
+### Automated canary promotion
+
+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 pod health.
+Based on analysis of the KPIs a canary is promoted or aborted, and the analysis result is published to Slack.
+
+![Flagger Canary Stages](https://raw.githubusercontent.com/weaveworks/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:1.4.1
+```
+
+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       2019-05-06T14:05:07Z

+prod        backend   Failed        0        2019-05-04T17:05:07Z
+```
+
+### Automated rollback
+
+During the canary analysis you can generate HTTP 500 errors to test if Flagger pauses and rolls back the faulted version.
+
+Trigger another canary deployment:
+
+```bash
+kubectl -n test set image deployment/podinfo \
+podinfod=quay.io/stefanprodan/podinfo:1.4.2
+```
+
+Generate HTTP 500 errors:
+
+```bash
+watch curl http://app.example.com/status/500
+```
+
+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.
+
+```text
+kubectl -n test describe canary/podinfo
+

+
+### Custom metrics
+
+The canary analysis can be extended with Prometheus queries.
+
+The demo app is instrumented with Prometheus so you can create a custom check that will use the HTTP request duration 
+histogram to validate the canary. 
+
+Edit the canary analysis and add the following metric:
+
+```yaml
+  canaryAnalysis:
+    metrics:
+    - name: "latency"
+      threshold: 0.5
+      interval: 1m
+      query: |
+        histogram_quantile(0.99,
+          sum(
+            rate(
+              http_request_duration_seconds_bucket{
+                kubernetes_namespace="test",
+                kubernetes_pod_name=~"podinfo-[0-9a-zA-Z]+(-[0-9a-zA-Z]+)"
+              }[1m]
+            )
+          ) by (le)
+        )
+```
+
+The threshold is set to 500ms so if the average request duration in the last minute 
+goes over half a second then the analysis will fail and the canary will not be promoted.
+
+Trigger a canary deployment by updating the container image:
+
+```bash
+kubectl -n test set image deployment/podinfo \
+podinfod=quay.io/stefanprodan/podinfo:1.4.3
+```
+
+Generate high response latency:
+
+```bash
+watch curl http://app.exmaple.com/delay/2
+```
+
+Watch Flagger logs:
+
+```
+kubectl -n nginx-ingress logs deployment/flagger -f | 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
+Halt podinfo.test advancement latency 1.20 > 0.5
+Halt podinfo.test advancement latency 1.45 > 0.5
+Halt podinfo.test advancement latency 1.60 > 0.5
+Halt podinfo.test advancement latency 1.69 > 0.5
+Halt podinfo.test advancement latency 1.70 > 0.5
+Rolling back podinfo.test failed checks threshold reached 5
+Canary failed! Scaling down podinfo.test
+```
+
+If you have Slack configured, Flagger will send a notification with the reason why the canary failed.
+
+### A/B Testing 
+
+Besides weighted routing, Flagger can be configured to route traffic to the canary based on HTTP match conditions.
+In an A/B testing scenario, you'll be using HTTP headers or cookies to target a certain segment of your users.
+This is particularly useful for frontend applications that require session affinity.
+
+![Flagger A/B Testing Stages](https://raw.githubusercontent.com/weaveworks/flagger/master/docs/diagrams/flagger-abtest-steps.png)
+
+Edit the canary analysis, remove the max/step weight and add the match conditions and iterations:
+
+```yaml
+  canaryAnalysis:
+    interval: 1m
+    threshold: 10
+    iterations: 10
+    match:
+      # curl -H 'X-Canary: insider' http://app.example.com
+      - headers:
+          x-canary:
+            exact: "insider"
+      # curl -b 'canary=always' http://app.example.com
+      - headers:
+          cookie:
+            exact: "canary"
+    metrics:
+    - name: request-success-rate
+      threshold: 99
+      interval: 1m
+    webhooks:
+      - name: load-test
+        url: http://localhost:8888/
+        timeout: 5s
+        metadata:
+          type: cmd
+          cmd: "hey -z 1m -q 10 -c 2 -H 'Cookie: canary=always' http://app.example.com/"
+          logCmdOutput: "true"
+```
+
+The above configuration will run an analysis for ten minutes targeting users that have a `canary` cookie set to `always` or 
+those that call the service using the `X-Canary: insider` header.
+
+Trigger a canary deployment by updating the container image:
+
+```bash
+kubectl -n test set image deployment/podinfo \
+podinfod=quay.io/stefanprodan/podinfo:1.5.0
+```
+
+Flagger detects that the deployment revision changed and starts the A/B testing:
+
+```text
+kubectl -n test describe canary/podinfo

+/*
+Simple library for retry mechanism
+
+slightly inspired by [Try::Tiny::Retry](https://metacpan.org/pod/Try::Tiny::Retry)
+
+SYNOPSIS
+
+http get with retry:
+
+	url := "http://example.com"
+	var body []byte
+
+	err := retry.Do(
+		func() error {
+			resp, err := http.Get(url)
+			if err != nil {
+				return err
+			}
+			defer resp.Body.Close()
+			body, err = ioutil.ReadAll(resp.Body)
+			if err != nil {
+				return err
+			}
+
+			return nil
+		},
+	)
+
+	fmt.Println(body)
+
+[next examples](https://github.com/avast/retry-go/tree/master/examples)
+
+
+SEE ALSO
+
+* [giantswarm/retry-go](https://github.com/giantswarm/retry-go) - slightly complicated interface.
+
+* [sethgrid/pester](https://github.com/sethgrid/pester) - only http retry for http calls with retries and backoff
+
+* [cenkalti/backoff](https://github.com/cenkalti/backoff) - Go port of the exponential backoff algorithm from Google's HTTP Client Library for Java. Really complicated interface.
+
+* [rafaeljesus/retry-go](https://github.com/rafaeljesus/retry-go) - looks good, slightly similar as this package, don't have 'simple' `Retry` method
+
+* [matryer/try](https://github.com/matryer/try) - very popular package, nonintuitive interface (for me)
+
+BREAKING CHANGES
+
+1.0.2 -> 2.0.0
+
+* argument of `retry.Delay` is final delay (no multiplication by `retry.Units` anymore)
+
+* function `retry.Units` are removed
+
+* [more about this breaking change](https://github.com/avast/retry-go/issues/7)
+
+
+0.3.0 -> 1.0.0
+
+* `retry.Retry` function are changed to `retry.Do` function
+
+* `retry.RetryCustom` (OnRetry) and `retry.RetryCustomWithOpts` functions are now implement via functions produces Options (aka `retry.OnRetry`)

+Package gogoproto provides extensions for protocol buffers to achieve:
+
+  - fast marshalling and unmarshalling.
+  - peace of mind by optionally generating test and benchmark code.
+  - more canonical Go structures.
+  - less typing by optionally generating extra helper code.
+  - goprotobuf compatibility
+
+More Canonical Go Structures
+
+A lot of time working with a goprotobuf struct will lead you to a place where you create another struct that is easier to work with and then have a function to copy the values between the two structs.
+You might also find that basic structs that started their life as part of an API need to be sent over the wire. With gob, you could just send it. With goprotobuf, you need to make a parallel struct.
+Gogoprotobuf tries to fix these problems with the nullable, embed, customtype and customname field extensions.
+
+  - nullable, if false, a field is generated without a pointer (see warning below).
+  - embed, if true, the field is generated as an embedded field.
+  - customtype, It works with the Marshal and Unmarshal methods, to allow you to have your own types in your struct, but marshal to bytes. For example, custom.Uuid or custom.Fixed128
+  - customname (beta), Changes the generated fieldname. This is especially useful when generated methods conflict with fieldnames.
+  - casttype (beta), Changes the generated fieldtype.  All generated code assumes that this type is castable to the protocol buffer field type.  It does not work for structs or enums.
+  - castkey (beta), Changes the generated fieldtype for a map key.  All generated code assumes that this type is castable to the protocol buffer field type.  Only supported on maps.
+  - castvalue (beta), Changes the generated fieldtype for a map value.  All generated code assumes that this type is castable to the protocol buffer field type.  Only supported on maps.
+
+Warning about nullable: According to the Protocol Buffer specification, you should be able to tell whether a field is set or unset. With the option nullable=false this feature is lost, since your non-nullable fields will always be set. It can be seen as a layer on top of Protocol Buffers, where before and after marshalling all non-nullable fields are set and they cannot be unset.
+
+Let us look at:
+
+	github.com/gogo/protobuf/test/example/example.proto
+
+for a quicker overview.
+
+The following message:
+
+  package test;
+
+  import "github.com/gogo/protobuf/gogoproto/gogo.proto";
+
+	message A {
+		optional string Description = 1 [(gogoproto.nullable) = false];
+		optional int64 Number = 2 [(gogoproto.nullable) = false];
+		optional bytes Id = 3 [(gogoproto.customtype) = "github.com/gogo/protobuf/test/custom.Uuid", (gogoproto.nullable) = false];
+	}
+
+Will generate a go struct which looks a lot like this:
+
+	type A struct {
+		Description string
+		Number      int64
+		Id          github_com_gogo_protobuf_test_custom.Uuid
+	}
+
+You will see there are no pointers, since all fields are non-nullable.
+You will also see a custom type which marshals to a string.
+Be warned it is your responsibility to test your custom types thoroughly.
+You should think of every possible empty and nil case for your marshaling, unmarshaling and size methods.
+
+Next we will embed the message A in message B.
+
+	message B {
+		optional A A = 1 [(gogoproto.nullable) = false, (gogoproto.embed) = true];
+		repeated bytes G = 2 [(gogoproto.customtype) = "github.com/gogo/protobuf/test/custom.Uint128", (gogoproto.nullable) = false];
+	}
+
+See below that A is embedded in B.
+
+	type B struct {
+		A
+		G []github_com_gogo_protobuf_test_custom.Uint128
+	}
+
+Also see the repeated custom type.
+
+	type Uint128 [2]uint64
+
+Next we will create a custom name for one of our fields.
+
+	message C {
+		optional int64 size = 1 [(gogoproto.customname) = "MySize"];
+	}
+
+See below that the field's name is MySize and not Size.
+
+	type C struct {
+		MySize		*int64
+	}
+
+The is useful when having a protocol buffer message with a field name which conflicts with a generated method.
+As an example, having a field name size and using the sizer plugin to generate a Size method will cause a go compiler error.
+Using customname you can fix this error without changing the field name.
+This is typically useful when working with a protocol buffer that was designed before these methods and/or the go language were avialable.
+
+Gogoprotobuf also has some more subtle changes, these could be changed back:
+
+  - the generated package name for imports do not have the extra /filename.pb,
+  but are actually the imports specified in the .proto file.
+
+Gogoprotobuf also has lost some features which should be brought back with time:
+
+  - Marshalling and unmarshalling with reflect and without the unsafe package,
+  this requires work in pointer_reflect.go
+
+Why does nullable break protocol buffer specifications:
+
+The protocol buffer specification states, somewhere, that you should be able to tell whether a
+field is set or unset.  With the option nullable=false this feature is lost,
+since your non-nullable fields will always be set.  It can be seen as a layer on top of
+protocol buffers, where before and after marshalling all non-nullable fields are set
+and they cannot be unset.
+
+Goprotobuf Compatibility:
+
+Gogoprotobuf is compatible with Goprotobuf, because it is compatible with protocol buffers.
+Gogoprotobuf generates the same code as goprotobuf if no extensions are used.
+The enumprefix, getters and stringer extensions can be used to remove some of the unnecessary code generated by goprotobuf:
+
+  - gogoproto_import, if false, the generated code imports github.com/golang/protobuf/proto instead of github.com/gogo/protobuf/proto.
+  - goproto_enum_prefix, if false, generates the enum constant names without the messagetype prefix
+  - goproto_enum_stringer (experimental), if false, the enum is generated without the default string method, this is useful for rather using enum_stringer, or allowing you to write your own string method.
+  - goproto_getters, if false, the message is generated without get methods, this is useful when you would rather want to use face
+  - goproto_stringer, if false, the message is generated without the default string method, this is useful for rather using stringer, or allowing you to write your own string method.
+  - goproto_extensions_map (beta), if false, the extensions field is generated as type []byte instead of type map[int32]proto.Extension
+  - goproto_unrecognized (beta), if false, XXX_unrecognized field is not generated. This is useful in conjunction with gogoproto.nullable=false, to generate structures completely devoid of pointers and reduce GC pressure at the cost of losing information about unrecognized fields.
+  - goproto_registration (beta), if true, the generated files will register all messages and types against both gogo/protobuf and golang/protobuf. This is necessary when using third-party packages which read registrations from golang/protobuf (such as the grpc-gateway).
+
+Less Typing and Peace of Mind is explained in their specific plugin folders godoc:
+
+	- github.com/gogo/protobuf/plugin/<extension_name>
+
+If you do not use any of these extension the code that is generated
+will be the same as if goprotobuf has generated it.
+
+The most complete way to see examples is to look at
+
+	github.com/gogo/protobuf/test/thetest.proto
+
+Gogoprototest is a seperate project,
+because we want to keep gogoprotobuf independent of goprotobuf,
+but we still want to test it thoroughly.
