pods with init container with `restartPolicy: Always` stay in `Init` status

[Shohou]

Describe the bug
I'm using kubernetes 1.29 and created a pod with normal container and init container which has restartPolicy: Always. In k9s pod always stays in Init:1/2 state, while kubectl get po <name> shows state Running

To Reproduce
Steps to reproduce the behavior:

1. Create a pod with init container with restartPolicy: Always
2. Check pod status in k9s
3. Status will be Init:1/2

Expected behavior
Status should be Running

Versions (please complete the following information):

• K9s: [e.g. 0.31.7]
• K8s: [e.g. 1.29.0]

@Shohou Can't seem to repro this ;( showing 1/1 Running.

What am I missing?

apiVersion: apps/v1
kind: Deployment
metadata:
  name: nginx
  labels:
    app: nginx
spec:
  replicas: 1
  selector:
    matchLabels:
      app: nginx
  template:
    metadata:
      labels:

      containers:
        - name: nginx

@derailed try this:

apiVersion: apps/v1
kind: Deployment
metadata:
  name: k9s-test
  labels:
    app: nginx
spec:
  replicas: 1
  selector:
    matchLabels:

        app: nginx
    spec:
      initContainers:
        - name: init-1
          image: busybox
          command: ['sleep', '1000000']
          restartPolicy: Always
      containers:
        - name: nginx
          image: nginx
          imagePullPolicy: IfNotPresent
          ports:
            - containerPort: 80

@Shohou Did I miss the memo??
Isn't restartPolicy an attribute of pods and not containers?
This manifest crocks on k8s 1.27 clusters ;(

[Shohou]

This is new feature of kubernetes 1.29 - https://kubernetes.io/docs/concepts/workloads/pods/sidecar-containers/
makes sidecar container out of init container

@Shohou Thank you for the correction Dmitry!
I was just spinning up a 1.29 cluster. I'll take a peek...
