For more details on how custom metrics can be used, please read the [metrics docs](usage/metrics.md).
#### Istio Gateway API
If you're using Istio with Gateway API, the Prometheus query needs to include `reporter="source"`. For example, to calculate HTTP requests error percentage, the query would be:
```javascript
100 - sum(
rate(
istio_requests_total{
reporter="source",
destination_workload_namespace=~"$namespace",
destination_workload=~"$workload",
response_code!~"5.*"

# Gateway API Canary Deployments
This guide shows you how to use Gateway API and Flagger to automate canary deployments.
![Flagger Canary Stages](https://raw.githubusercontent.com/fluxcd/flagger/main/docs/diagrams/flagger-gatewayapi-canary.png)
## Prerequisites
Flagger requires a Kubernetes cluster **v1.16** or newer and any mesh/ingress that implements the `v1alpha2` of Gateway API. We'll be using Contour for the sake of this tutorial, but you can use any other implementation.
Install the GatewayAPI CRDs:
```bash
kubectl apply -k github.com/kubernetes-sigs/gateway-api/config/crd?ref=v0.4.1
```
Install a cluster-wide GatewayClass; a Gateway belonging to the GatewayClass and Contour components in the `projectcontour` namespace:
```bash
kubectl apply -f https://raw.githubusercontent.com/projectcontour/contour/release-1.20/examples/render/contour.yaml
```
Install Flagger in the `flagger-system` namespace:
```bash
kubectl apply -k github.com/fluxcd/flagger//kustomize/gatewayapi
```
## Bootstrap
Flagger takes a Kubernetes deployment and optionally a horizontal pod autoscaler \(HPA\), then creates a series of objects \(Kubernetes deployments, ClusterIP services, HTTPRoutes for the Gateway\). These objects expose the application inside the mesh 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 -k https://github.com/fluxcd/flagger//kustomize/podinfo?ref=main
```
Deploy the load testing service to generate traffic during the canary analysis:
```bash
kubectl apply -k https://github.com/fluxcd/flagger//kustomize/tester?ref=main
```
Create metric templates targeting the Prometheus server in the `flagger-system` namespace. The PromQL queries below are meant for `Envoy`, but you can [change it to your ingress/mesh provider](https://docs.flagger.app/faq#metrics) accordingly.
```yaml
apiVersion: flagger.app/v1beta1
kind: MetricTemplate
metadata:
name: latency
namespace: flagger-system
spec:
provider:
type: prometheus
address: http://flagger-prometheus:9090
query: |
histogram_quantile(0.99,
sum(
rate(
envoy_cluster_upstream_rq_time_bucket{
envoy_cluster_name=~"{{ namespace }}_{{ target }}-canary_[0-9a-zA-Z-]+",
}[{{ interval }}]
)
) by (le)
)/1000
---
apiVersion: flagger.app/v1beta1
kind: MetricTemplate
metadata:
name: error-rate
namespace: flagger-system
spec:
provider:
type: prometheus
address: http://flagger-prometheus:9090
query: |
100 - sum(
rate(
envoy_cluster_upstream_rq{
envoy_cluster_name=~"{{ namespace }}_{{ target }}-canary_[0-9a-zA-Z-]+",
envoy_response_code!~"5.*"
}[{{ interval }}]
)
)
/
sum(
rate(
envoy_cluster_upstream_rq{
envoy_cluster_name=~"{{ namespace }}_{{ target }}-canary_[0-9a-zA-Z-]+",
}[{{ interval }}]
)
)
* 100
```
Save the above resource as metric-templates.yaml and then apply it:
```bash
kubectl apply -f metric-templates.yaml
```
Create a canary custom resource \(replace "loaclproject.contour.io" with your own domain\):
```yaml
apiVersion: flagger.app/v1beta1
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/v2beta2
kind: HorizontalPodAutoscaler
name: podinfo
service:
# service port number
port: 9898
# container port number or name (optional)
targetPort: 9898
# Gateway API HTTPRoute host names
hosts:
- localproject.contour.io
# Reference to the Gateway that the generated HTTPRoute would attach to.
gatewayRefs:
- name: contour
namespace: projectcontour
analysis:
# schedule interval (default 60s)
interval: 1m
# max number of failed metric checks before rollback
threshold: 5
# max traffic percentage routed to canary
# percentage (0-100)
maxWeight: 50
# canary increment step
# percentage (0-100)
stepWeight: 10
metrics:
- name: error-rate
# max error rate (5xx responses)
# percentage (0-100)
templateRef:
name: error-rate
namespace: flagger-system
thresholdRange:
max: 1
interval: 1m
- name: latency
templateRef:
name: latency
namespace: flagger-system
# seconds
thresholdRange:
max: 0.5
interval: 30s
# testing (optional)
webhooks:
- name: smoke-test
type: pre-rollout
url: http://flagger-loadtester.test/
timeout: 15s
metadata:
type: bash
cmd: "curl -sd 'anon' http://podinfo-canary.test:9898/token | grep token"
- name: load-test
url: http://flagger-loadtester.test/
timeout: 5s
metadata:
cmd: "hey -z 2m -q 10 -c 2 -host localproject.contour.io http://envoy.projectcontour/"
```
Save the above resource as podinfo-canary.yaml and then apply it:
```bash
kubectl apply -f ./podinfo-canary.yaml
```
When the canary analysis starts, Flagger will call the pre-rollout webhooks before routing traffic to the canary. The canary analysis will run for five minutes while validating the HTTP metrics and rollout hooks every minute.
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
httproutes.gateway.networking.k8s.io/podinfo
```
## Expose the app outside the cluster
Find the external address of Contour's Envoy load balancer:
```bash
export ADDRESS="$(kubectl -n projectcontour get svc/envoy -ojson \
| jq -r ".status.loadBalancer.ingress[].hostname")"
echo $ADDRESS
```
Configure your DNS server with a CNAME record \(AWS\) or A record \(GKE/AKS/DOKS\) and point a domain e.g. `localproject.contour.io` to the LB address.
Now you can access the podinfo UI using your domain address.
Note that you should be using HTTPS when exposing production workloads on internet. You can obtain free TLS certs from Let's Encrypt, read this [guide](https://github.com/stefanprodan/eks-contour-ingress) on how to configure cert-manager to secure Contour with TLS certificates.
If you're using a local cluster via kind/k3s you can port forward the Envoy LoadBalancer service:
```bash
kubectl port-forward -n projectcontour svc/envoy 8080:80
```
Now you can access podinfo via `curl -H "Host: localproject.contour.io" localhost:8080`
## Automated canary promotion
Trigger a canary deployment by updating the container image:
```bash
kubectl -n test set image deployment/podinfo \
podinfod=stefanprodan/podinfo:6.0.1
```
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
Phase: Succeeded
Events:
Type Reason Age From Message
---- ------ ---- ---- -------

Warning Synced 15s flagger Waiting for podinfo-primary.test rollout to finish: 1 of 2 updated replicas are available
Normal Synced 5s flagger Promotion completed! Scaling down podinfo.test
```
**Note** that if you apply new changes to the deployment during the canary analysis, Flagger will restart the analysis.
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
You can monitor how Flagger progressively changes the weights of the HTTPRoute object that is attahed to the Gateway with:
```bash
watch kubectl get httproute -n test podinfo -o=jsonpath='{.spec.rules}'
```
You can monitor all canaries with:
```bash
watch kubectl get canaries --all-namespaces
NAMESPACE NAME STATUS WEIGHT LASTTRANSITIONTIME
test podinfo Progressing 15 2022-01-16T14:05:07Z
prod frontend Succeeded 0 2022-01-15T16:15:07Z
prod backend Failed 0 2022-01-14T17:05:07Z
```
## Automated rollback
During the canary analysis you can generate HTTP 500 errors and high latency to test if Flagger pauses the rollout.
Trigger another canary deployment:
```bash
kubectl -n test set image deployment/podinfo \
podinfod=stefanprodan/podinfo:6.0.2
```
Exec into the load tester pod with:
```bash
kubectl -n test exec -it flagger-loadtester-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.
```text
kubectl -n test describe canary/podinfo
Status:
Canary Weight: 0
Failed Checks: 10

# 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.
