Bind mount failed #91

Open rothgar opened 2 days ago

rothgar commented 2 days ago

I'm trying to create a pod via kubectl with this spec

apiVersion: v1
kind: Pod
metadata:
  name: nginx-pod
  labels:
    app: nginx
spec:
  containers:
  - name: nginx
    image: nginx:latest
    ports:
    - containerPort: 80
  automountServiceAccountToken: false

but when I apply it the docker container gets created but isn't running. I see this error in the k2d logs

ERROR   controller/controller.go:174    unable to create pod   {"error": "Error response from daemon: Bind mount failed: '/var/lib/k2d/secrets/k2d-k2d-serviceaccount-k2dsec-token' does not exists", "request_id": "5af66fd9-7991-4ee6-92c8-5961713f962b"}

The pod stays in an Unknown state

k get pods
NAME            READY   STATUS    RESTARTS   AGE
nginx           0/1     Unknown   0          3m13s

If I manually create an empty file in that location it continues but errors on k2d-k2d-serviceaccount-k2dsec-ca.crt not existing. I can manually create an empty file for that too but it won't continue past that error.
