Canary deployments: Go easy with Ketch 0.2!

What is a Canary Deployment? ๐Ÿค”

Why makes Ketch special for Canary deployments?

  • Introduce a method to deploy the canary change to some percentage of users for testing the new version against the baseline. It becomes a bit harder and tricky when 3rd party routers/Service meshes/Ingress Controllers are integrated into the Kubernetes cluster. For example, Traefik or Istio.
  • Evaluating the new version regularly and check if it is not in a broken/failed state.
  • Increase the user traffic to the new version manually with time.
  • Rollback if the new version fails at some point in time.
  • Of course, writing the boring K8s YAML. ๐Ÿ˜ฉ

Letโ€™s automate Canary rollouts with Ketch! โ›ต๏ธ

$ sudo route -n add -host -net $(kubectl get svc traefik -o jsonpath='{.spec.clusterIP}') $(minikube ip -p ketch)
$ ketch app deploy a1 -i docker.io/dockercloud/hello-world --steps 10  --step-interval 1h

Automatic Rollback

  • Ketch now supports Traefik 2.x and fully working with secure TLS support.
  • Ketch now supports Istio 1.8.x and above and fully working with secure TLS support.
