Notes

This is a sample canary deployement of an app to fix a bug after it has been deployed to prod. Deploy to pro using train-schedule-kube.yml before adding train-schedule-kube-canary.yml for the canary version.

Edit the initial Jenkinsfile to add stage CanaryDeploy, env CANARY_REPLICAS & canary deployment yml file in deployProduction stage.

Check running pods using kubectl get pods -w. Use cat ~/.kube/config to get content of kubeconfig credentials for Jenkins set-up.
