Pod stuck at ContainerCreating when given an invalid Pod definition #88166

What happened:

I created a pod with a downwardAPI volume where I exposed a resourceFieldRef with a containerName that didn't match the name of any of the containers in the pod.

I would have expected this to fail the container creation.
Instead, it just got stuck indefinitely.

What you expected to happen:

I would have expected the pod to fail to create and a clear error to appear somewhere.

Instead, the pod creation gets stuck in ContainerCreating:

➜  k get pods
NAME              READY   STATUS              RESTARTS   AGE
downwardapi-pod   0/1     ContainerCreating   0          7m8s

note: even after 7 minutes the container is still "creating"

Describing the pod shows the warning that allowed me to understand the issue:

How to reproduce it (as minimally and precisely as possible):

Create this pod:

apiVersion: v1
kind: Pod
  name: downwardapi-pod

  - name: sleepy
    image: alpine
    command: ["/bin/sh", "-c", "--"]
    args: ["while true; do sleep 300; done"]
    - name: podinfo
      mountPath: /etc/podinfo
  - name: podinfo
      - path: "cpu_limit"
          containerName: not-a-container
          resource: limits.cpu
          divisor: 1m
