Manage deployments using the Kubernetes REST API

Question

I need to delete a kubernetes deployment resource using REST API. That's possible and it works, but I just found out that while the deployment resource is deleted ok, its associated ReplicaSet is not.

That means its pods are still running.

I don't know how to find name of a ReplicaSet associated to a Deployment.

I can see it when using kubectl: kubectl describe deployment mydeployment, but I can't find a REST method to get that information.

Is there a way?

Answer 1

An easy way to find the calls associated would be to use the associated kubectl command with a higher level of verbosity (--v=6 or --v=9).

#~ kubectl delete deployment nginx-deployment --v=6
