unable to list pods in any state except completed

4/1/2020

Problem: I want to list all pods except those NOT in Completed state.

field selector still outputs pods in Completed phase when Selected not Completed in kubectl command

Proposed Solution: observe that am also getting pods in Completed phase.

kubectl get pods --all-namespaces --field-selector=spec.nodeName=node1,status.phase!=Completed --no-headers

Try this:

kubectl get pod -o=json | jq '.items[]|select(any( .status.containerStatuses[]; .state.terminated.reason!="Completed"))|.metadata.name'

This will list down all the pods where the state of the pod is anything other than completed.

For testing change != with \== to list Completed pod.

Specifically, if you are looking for cronjobs containers only that were in not completed state using kubectl native jsonpath use this:

kubectl get pod -o jsonpath='{.items[?(@.status.containerStatuses[*].state.terminated.reason!="Completed")].metadata.name}'

I hope it helps.

Completed is not a valid Pod Phase, use Succeeded instead.

Pending, Running, Succeeded, Failed and Unknown are the valid values for Pod Phase.

To get the non-completed pods,

kubectl get pods --all-namespaces --field-selector=spec.nodeName=node1,status.phase!=Succeeded --no-headers
