Valid container name info needed in kubectl logs/exec output #1768
Description
What would you like to be added?
Add container name info in kubectl logs xxx and kubectl exec xxx output, when there are multiple containers in a pod. Currently, there is no valid container name info in the output.
Current:
kubectl logs test-pod -c abc
error: container abc is not valid for pod test-pod
kubectl exec -it test-pod -c abc -- sh
Error from server (BadRequest): container abc is not valid for pod test-pod
Expected:
kubectl logs test-pod -c abc
error: container abc is not valid for pod test-pod out of: main-0, main-1, main-2, init-0 (init), init-1 (init)
kubectl exec -it test-pod -c abc -- sh
Error from server (BadRequest): container abc is not valid for pod test-pod out of: main-0, main-1, main-2, init-0 (init), init-1 (init)
Why is this needed?
When a pod with multiple containers, there is no valid container name info in the kubectl logs xxx and kubectl exec xxx output, need to add containers name info to choose easily.
Test yaml:
apiVersion: v1
kind: Pod
metadata:
name: test-pod
spec:
initContainers:
- name: init-0
image: busybox
command:
- echo
- msg from init-0
- name: init-1
image: busybox
command:
- echo
- msg from init-1
containers:
- name: main-0
image: busybox
command:
- /bin/sh
- -c
- sleep 3600
- name: main-1
image: busybox
command:
- /bin/sh
- -c
- sleep 3600
- name: main-2
image: busybox
command:
- /bin/sh
- -c
- sleep 3600
kubectl apply -f test-pod.yaml, then:
kubectl logs test-pod -c abckubectl exec -it test-pod -c abc -- sh
will reproduce this issue.
