Kubernetes Canary Deployments

wikipedia:Canary deployments

• https://kubernetes.io/docs/concepts/cluster-administration/manage-deployment/#canary-deployments

name: frontend
replicas: 3
...
labels:
   app: guestbook
   tier: frontend
   track: stable
...
image: gb-frontend:v3
and then you can create a new release of the guestbook frontend that carries the track label with different value (i.e. canary), so that two sets of pods would not overlap:

name: frontend-canary
replicas: 1
...
labels:
   app: guestbook
   tier: frontend
   track: canary
...
image: gb-frontend:v4

Errors

• Error: creating Synthetics Canary ... Canary name already exists.
