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.
