 Flagger starts the load test for the canary service (green version) and checks the Prometheus metrics every 30 seconds.
 If the analysis result is positive, Flagger will promote the canary (green version) to primary (blue version).
 
+**When can I use traffic mirroring?**
+
+Traffic Mirroring is a pre-stage in a Canary (progressive traffic shifting) or
+Blue/Green deployment strategy. Traffic mirroring will copy each incoming
+request, sending one request to the primary and one to the canary service.
+The response from the primary is sent back to the user. The response from the canary
+is discarded.  Metrics are collected on both requests so that the deployment will
+only proceed if the canary metrics are healthy.
+
+Mirroring is supported by Istio only.
+
+In Istio, mirrored requests have `-shadow` appended to the `Host` (HTTP) or
+`Authority` (HTTP/2) header; for example requests to `podinfo.test` that are
+mirrored will be reported in telemetry with a destination host `podinfo.test-shadow`.
+
+Mirroring must only be used for requests that are **idempotent** or capable of
+being processed twice (once by the primary and once by the canary). Reads are
+idempotent. Before using mirroring on requests that may be writes, you should
+consider what will happen if a write is duplicated and handled by the primary
+and canary.
+
+To use mirroring, set `spec.canaryAnalysis.mirror` to `true`. Example for
+traffic shifting:
+
+```yaml

+### Istio routing
+
+**How does Flagger interact with Istio?**
+
+Flagger creates an Istio Virtual Service and Destination Rules based on the Canary service spec. 
+The service configuration lets you expose an app inside or outside the mesh.
+You can also define traffic policies, HTTP match conditions, URI rewrite rules, CORS policies, timeout and retries.
+
+The following spec exposes the `frontend` workload inside the mesh on `frontend.test.svc.cluster.local:9898` 
+and outside the mesh on `frontend.example.com`. You'll have to specify an Istio ingress gateway for external hosts.
+
+```yaml
+apiVersion: flagger.app/v1alpha3
+kind: Canary
+metadata:
+  name: frontend
+  namespace: test
+spec:
+  service:
+    # container port
+    port: 9898
+    # service port name (optional, will default to "http")
+    portName: http-frontend
+    # Istio gateways (optional)
+    gateways:
+    - public-gateway.istio-system.svc.cluster.local
+    - mesh
+    # Istio virtual service host names (optional)
+    hosts:
+    - frontend.example.com
+    # Istio traffic policy
+    trafficPolicy:
+      tls:
+        # use ISTIO_MUTUAL when mTLS is enabled
+        mode: DISABLE
+    # HTTP match conditions (optional)
+    match:
+      - uri:
+          prefix: /
+    # HTTP rewrite (optional)
+    rewrite:
+      uri: /
+    # Istio retry policy (optional)
+    retries:
+      attempts: 3
+      perTryTimeout: 1s
+      retryOn: "gateway-error,connect-failure,refused-stream"
+    # Add headers (optional)
+    headers:
+      request:
+        add:
+          x-some-header: "value"
+    # cross-origin resource sharing policy (optional)
+    corsPolicy:
+      allowOrigin:
+        - example.com
+      allowMethods:

+      allowCredentials: false
+      allowHeaders:
+        - x-some-header
+      maxAge: 24h
+```
+
+For the above spec Flagger will generate the following virtual service:
+
+```yaml
+apiVersion: networking.istio.io/v1alpha3
+kind: VirtualService
+metadata:
+  name: frontend
+  namespace: test
+  ownerReferences:

+      - example.com
+      maxAge: 24h
+    match:
+    - uri:
+        prefix: /
+    rewrite:
+      uri: /
+    route:
+    - destination:
+        host: podinfo-primary
+      weight: 100
+    - destination:
+        host: podinfo-canary
+      weight: 0
+    retries:
+      attempts: 3
+      perTryTimeout: 1s
+      retryOn: "gateway-error,connect-failure,refused-stream"
+```
+
+For each destination in the virtual service a rule is generated:
+
+```yaml
+apiVersion: networking.istio.io/v1alpha3
+kind: DestinationRule
+metadata:
+  name: frontend-primary
+  namespace: test
+spec:
+  host: frontend-primary
+  trafficPolicy:
+    tls:
+      mode: DISABLE
+---
+apiVersion: networking.istio.io/v1alpha3

+metadata:
+  name: frontend-canary
+  namespace: test
+spec:
+  host: frontend-canary
+  trafficPolicy:
+    tls:
+      mode: DISABLE
+```
+
+Flagger keeps in sync the virtual service and destination rules with the canary service spec.
+Any direct modification to the virtual service spec will be overwritten.
+
+To expose a workload inside the mesh on `http://backend.test.svc.cluster.local:9898`,
+the service spec can contain only the container port and the traffic policy:
+
+```yaml
+apiVersion: flagger.app/v1alpha3
+kind: Canary
+metadata:
+  name: backend
+  namespace: test
+spec:
+  service:
+    port: 9898
+    trafficPolicy:
+      tls:
+        mode: DISABLE
+```
+
+Based on the above spec, Flagger will create several ClusterIP services like:
+
+```yaml
+apiVersion: v1
+kind: Service
+metadata:
+  name: backend-primary
+  ownerReferences:
+  - apiVersion: flagger.app/v1alpha3
+    blockOwnerDeletion: true

+  - name: http
+    port: 9898
+    protocol: TCP
+    targetPort: 9898
+  selector:
+    app: backend-primary
+```
+
+Flagger works for user facing apps exposed outside the cluster via an ingress gateway
+and for backend HTTP APIs that are accessible only from inside the mesh.

 Make sure that the analysis threshold is lower than the number of iterations.
 
+### Blue/Green deployments
+
+For applications that are not deployed on a service mesh, Flagger can orchestrate blue/green style deployments 
+with Kubernetes L4 networking. When using Istio you have the option to mirror traffic between blue and green.
+
+You can use the blue/green deployment strategy by replacing `stepWeight/maxWeight` with `iterations` in the `canaryAnalysis` spec:
+
+```yaml
+  canaryAnalysis:
+    # schedule interval (default 60s)
+    interval: 1m
+    # total number of iterations
+    iterations: 10
+    # max number of failed iterations before rollback
+    threshold: 2
+    # Traffic shadowing (compatible with Istio only)
+    mirror: true
+```
+
+With the above configuration Flagger will run conformance and load tests on the canary pods for ten minutes. 
+If the metrics analysis succeeds, live traffic will be switched from the old version to the new one when the
+canary is promoted.
+
+The blue/green deployment strategy is supported for all service mesh providers.
+
+Blue/Green rollout steps for service mesh:
+* scale up the canary (green)
+* run conformance tests for the canary pods
+* run load tests and metric checks for the canary pods
+* route traffic to canary
+* promote canary spec over primary (blue)
+* wait for primary rollout
+* route traffic to primary
+* scale down canary
+
+After the analysis finishes, the traffic is routed to the canary (green) before triggering the primary (blue)
+rolling update, this ensures a smooth transition to the new version avoiding dropping in-flight requests during
+the Kubernetes deployment rollout.

+### 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:
+    - headers:
+        x-canary:
+          exact: "insider"
+    webhooks:
+    - name: load-test
+      url: http://flagger-loadtester.test/
+      metadata:
+        cmd: "hey -z 1m -q 10 -c 2 -H 'X-Canary: insider' http://podinfo.test:9898/"
+```
+
+The above configuration will run an analysis for ten minutes targeting users that have a `X-Canary: insider` header.
+
+You can also use a HTTP cookie, to target all users with a `canary` cookie set to `insider` the match condition should be:
+
+```yaml
+match:
+- headers:
+    cookie:
+      regex: "^(.*?;)?(canary=insider)(;.*)?$"
+webhooks:
+- name: load-test

+### Traffic mirroring
+
+![Flagger Canary Traffic Shadowing](https://raw.githubusercontent.com/weaveworks/flagger/master/docs/diagrams/flagger-canary-traffic-mirroring.png)
+
+For applications that perform read operations, Flagger can be configured to drive canary releases with traffic mirroring.
+Istio traffic mirroring will copy each incoming request, sending one request to the primary and one to the canary service.
+The response from the primary is sent back to the user and the response from the canary is discarded.
+Metrics are collected on both requests so that the deployment will only proceed if the canary metrics are within the threshold values.
+
+Note that mirroring should be used for requests that are **idempotent** or capable of being processed twice
+(once by the primary and once by the canary).
+
+You can enable mirroring by replacing `stepWeight/maxWeight` with `iterations` and
+by setting `canaryAnalysis.mirror` to `true`:
+
+```yaml
+apiVersion: flagger.app/v1alpha3
+kind: Canary
+metadata:
+  name: podinfo
+  namespace: test
+spec:
+  canaryAnalysis:
+    # schedule interval
+    interval: 1m
+    # max number of failed metric checks before rollback
+    threshold: 5
+    # total number of iterations
+    iterations: 10
+    # enable traffic shadowing 
+    mirror: true
+    metrics:
+    - name: request-success-rate
+      threshold: 99
+      interval: 1m
+    - name: request-duration
+      threshold: 500
+      interval: 1m
+    webhooks:
+      - name: acceptance-test
+        type: pre-rollout
+        url: http://flagger-loadtester.test/
+        timeout: 30s
+        metadata:
+          type: bash
+          cmd: "curl -sd 'test' http://podinfo-canary:9898/token | grep token"
+      - name: load-test
+        url: http://flagger-loadtester.test/
+        timeout: 5s
+        metadata:
+          cmd: "hey -z 1m -q 10 -c 2 http://podinfo.test:9898/"
+```
+
+With the above configuration, Flagger will run a canary release with the following steps:
+* detect new revision (deployment spec, secrets or configmaps changes)
+* scale from zero the canary deployment
+* wait for the HPA to set the canary minimum replicas
+* check canary pods health
+* run the acceptance tests
+* abort the canary release if tests fail
+* start the load tests
+* mirror traffic from primary to canary
+* check request success rate and request duration every minute
+* abort the canary release if the metrics check failure threshold is reached
+* stop traffic mirroring after the number of iterations is reached
+* route live traffic to the canary pods
+* promote the canary (update the primary secrets, configmaps and deployment spec)
+* wait for the primary deployment rollout to finish
+* wait for the HPA to set the primary minimum replicas
+* check primary pods health
+* switch live traffic back to primary
+* scale to zero the canary
+* send notification with the canary analysis result
+
+The above procedure can be extended with [custom metrics](https://docs.flagger.app/how-it-works#custom-metrics) checks,
+[webhooks](https://docs.flagger.app/how-it-works#webhooks),
+[manual promotion](https://docs.flagger.app/how-it-works#manual-gating) approval and
+[Slack or MS Teams](https://docs.flagger.app/usage/alerting) notifications.
