Discussion:
When replacing an existing pod, the command fails as it tries to create a pod with a name that is still used by terminating pod. How does the option works? deletes a pod (e.g. mypod) creates a new pod with the same name (mypod) What happens? As the command tries to recreate the pod, it fails as the is in state. Thus it can not be created. The problem is the does not wait for a pod to be deleted. Reproducer: run mypod --image=yapei/hello-openshift --generator=run-pod/v1 get pod mypod -o yaml replace -f --force The last command ends with:
option introduce by
With set to positive value, what should be the default behaviour of the command? When set to , should the command hang for and then create the pod? Or is there a way to create a callback (inside a scheduler?) that creates the pod once the current one is deleted?
You could watch for the resource to be deleted and create after you see the deletion happen
have you ever tried to set , I think this will do a non graceful deletion. should make sure the old resource is deleted before it creates a new resource, if not, that's a bug.
Though the help says the is to be used only with , it returns the error above.
Then I think there are two issues we need to track: 1. option should be ignored or just returns error if users are not using option. 2. should always make sure the old resource has been deleted before create the new resource.
