@openshift/cli-review PTAL

[fabianofranz]

Once kubernetes/kubernetes#34502 and #10993 merges, we could add a verify-cli-conventions.sh check to make sure every command under create has a --dry-run flag.

[fabianofranz]

Overall LGTM, let's see how upstream goes.

[juanvallejo]

@fabianofranz Sounds good, thanks for taking a look! I've added the oc create -f ... command as well to the list, per this suggestion upstream.

[juanvallejo]

@fabianofranz Upstream merged! kubernetes/kubernetes#34028
@soltysh Added the dry-run option to kubectl apply to this PR as well if that is okay with you: d9d259b

oc create route edge --dry-run -o yaml doesn't seem to work

[juanvallejo]

@smarterclayton thanks, will address this
