Volumes, Multi-Containers & Logging for CKAD
In this lab, you will get hands-on experience with key Kubernetes skills. You will learn how to create persistent storage, attach and mount it to a running NGINX pod, and set up multi-container pods that share data using an emptyDir volume. You will also verify log sharing, implement centralized logging by redirecting logs to a shared folder, use a sidecar container to stream or send the logs, mount volumes as read-only in the sidecar, and copy logs for analysis—all focused on building practical, real-world Kubernetes skills.

Challenge
Use Persistent Volumes
- Create a PersistentVolume task-pv (hostPath /tmp/data, 1Gi).
- Create a matching PersistentVolumeClaim task-pvc.
- Attach the PVC to a Pod running nginx, mounted at /usr/share/nginx/html.
- Use
kubectl exec
to write a file and verify persistence.
-
Challenge
Create Multi-Container Pods
- Create a Pod logger-pod with two containers.
- Use an emptyDir volume shared between both containers.
- Verify log sharing via
kubectl logs -c logger logger-pod
.
-
Challenge
Implement Centralized Logging Patterns
- Redirect application logs to a shared directory.
- Use a sidecar to continuously stream or ship logs.
- Explore mounting volumes read-only in the sidecar.
- Use
kubectl cp
to extract log files for analysis.
