Rollout restart statefulset using kubectl proxy

4/29/2020

I have started kubectl proxy from within my pods and am able to access kubernetes APIs. I have a need to restart my statefulset.

Using kubectl, I would done this:

kubectl rollout restart statefulset my-statefulset

However, I would like to do this using the REST APIs. For instance, I can delete my pods, using this:

curl -XDELETE localhost:8080/api/v1/namespaces/default/pods

Is there any equivalent REST endpoint that I can use to rollout restart a statefulset?

I run your command kubectl rollout restart statefulset my-statefulset --v 10 and notice the output logs.

I figured out kubectl makes a patch request when I apply above command. And I am able to do that patch request using curl like following

curl -k --data '{"spec":{"template":{"metadata":{"annotations":{"kubectl.kubrnetes.io/restartedAt":"'"$(date +%Y-%m-%dT%T%z)"'"}}}}}'\
