attach-pvc-to-debug-pod

This guide demonstrates how to attach a Persistent Volume Claim (PVC) to a debug pod in Kubernetes. This is useful for inspecting data within a pod without restarting it.

YAML Configuration

apiVersion: v1
kind: Pod
metadata:
  name: pvc-debug-pod
spec:
  containers:
  - name: alpine
    image: alpine:latest
    command: ['sleep', 'infinity']
    volumeMounts:
    - name: mypvc
      mountPath: /data
  volumes:
  - name: mypvc
    persistentVolumeClaim:
      claimName: mypvc

Explanation

The YAML above defines a pod named pvc-debug-pod. The volumeMounts section specifies that the mypvc PVC should be mounted at the /data path inside the container. The volumes section defines the mypvc volume, linking it to the PVC with the same name. Remember to replace mypvc with the actual name of your PVC.

Further Steps

After creating this YAML file (e.g., pvc-debug-pod.yaml), you can apply it to your Kubernetes cluster using kubectl apply -f pvc-debug-pod.yaml. You can then access the data from the PVC within the container at the /data path.

Troubleshooting

If you encounter issues, check the Kubernetes logs for errors. Ensure the PVC exists and is bound to a Persistent Volume (PV). Verify that the pod is running and the container is accessible.
