kubectl retrieve update time for the resource

Question

I'm wondering whether it's possible to get the time where my resource was updated?

e.g. via

$ kubectl describe deployment/myapp

I can see CreationTimestamp but I want to know the last time new changes were introduced. Also is it possible to get a diff between two rollouts? For example with

$ kubectl rollout history deployment/myapp

I want to check the configuration difference between current version and the previous one. Is there a way I can do that?

Answer 1

Seems like these commands are sufficient

$ kubectl rollout history deployment myapp
$ kubectl rollout history deployment myapp --revision=76

and to check the difference (use diff or colordiff)

colordiff \
    <(kubectl rollout history deployment myapp --revision=76) \
    <(kubectl rollout history deployment myapp --revision=81)
