@mbohlool, I am trying to use replace_namespaced_pod(...), but when I execute the following lines

pod.spec.containers[0].image = 'busybox:1.26.1'
v1.replace_namespaced_pod(name=name, namespace="default", body=pod)

I get the error

kubernetes.client.rest.ApiException: (422)
Reason: Unprocessable Entity
HTTP response headers: HTTPHeaderDict({'Date': 'Sun, 25 Jun 2017 16:11:17 GMT', 'Content-Length': '604', 'Content-Type': 'application/json'}) HTTP response body: {"kind":"Status","apiVersion":"v1","metadata":{},"status":"Failure","message":"Pod \"busybox\" is invalid: spec: Forbidden: pod updates may not change fields other than containers[].image or spec.activeDeadlineSeconds or spec.tolerations (only additions to existing tolerations)","reason":"Invalid","details":{"name":"busybox","kind":"Pod","causes": [{"reason":"FieldValueForbidden","message":"Forbidden: pod updates may not change fields other than containers[].imageorspec.activeDeadlineSecondsorspec.tolerations (only additions to existing tolerations)","field":"spec"}]},"code":422}

From code, the only change I have made is to containers[*].image

That look like a usecase for "patch" not "replace". Have you tried that?

@mbohlool I was just trying to see how the "replace" command works with various object. I tried "patch" and it works fine for pods, and the "replace" command also works fine with ReplicationControllers and Deployments.

@mbohlool I don't think I have privs to add labels
