[Question] How do you find out what a pod belongs to (Rep. Controller, Deployment, Replica Set, etc.?

[jason-riddle]

Is this a request for help? (If yes, you should use our troubleshooting guide and community support channels, see http://kubernetes.io/docs/troubleshooting/.): No

What keywords did you search in Kubernetes issues before filing this one? (If you have found any duplicates, you should instead reply there.): It's a bit tough to search for this since this includes a lot of keywords.

Is this a BUG REPORT or FEATURE REQUEST? (choose one): Question

Pretty much what the title says. I'm asking because sometimes I want to kill a pod for good but I don't remember what I used to create it.

@jason-riddle I think you could check the created-by annotation of pod.

[jason-riddle]

@adohe But that's assuming it was set in the first place which I didn't do. However, your suggestion lead to the following.

With the describe call, you can just grep for Controllers.

kubectl describe pods dd-agent-4qwo1 | grep Controllers
# Controllers:      DaemonSet/dd-agent

In the case of a lone pod running, Controllers will be empty.

kubectl describe pods apache | grep Controllers
# Controllers:      <none>

Thanks!

Worked for me:

kubectl describe pod <Podname> -n <namespace> | grep "Controlled By"

Grep'ing Controlled By works with the latest version of the Kubernetes client and server as of this note while grep'ing Controllers no longer works as at some point the pod manifest has changed to print "Controlled By" instead of "Controllers".

using jsonpath can help too, if you want to check for more than 1:

kubectl  get pods -o jsonpath="{range .items[*]}{.metadata.name}{'-> Controlled by ->'}{.metadata.ownerReferences[0].kind}{': '}{.metadata.ownerReferences[0].name}{'\n'}"

So the question is how to determine the "Deployment"?
