Docker and Kubernetes Administration Intermediate lab 2

A learner provisions an isolated docker and kubernetes administration environment and completes a guided operational task.

Business context

Ultiblob uses this exercise to train container platform administrator candidates on realistic private-cloud lab operations rather than static videos.

Technical objective

Configure the core docker and kubernetes administration services, verify health, and record the result in the lab progress view.

Student instructions

  1. 1Open the lab workspace and review the topology map.
  2. 2Launch the required templates and wait for all provisioning checks to complete.
  3. 3Complete the configuration task in the course module.
  4. 4Run validation and capture the result for instructor review.
  5. 5Create a snapshot before any risky troubleshooting or failure exercise.

Troubleshooting

  • If access fails, confirm the bastion session is active and the instance is not expired.
  • If validation fails, inspect the lab event log before rerunning the check.
  • If configuration drifts, restore the latest clean snapshot and repeat the module task.

Cleanup

  • Export notes or reports required by the instructor.
  • Restore or delete temporary snapshots created during the exercise.
  • Use the teardown action when the module is complete or allow the TTL policy to expire the lab.

Required templates

  • Docker host - defined
  • Kubernetes node - defined
  • Ubuntu Server 24.04 - available

Validation checks

  • Docker running: Docker daemon responds and can run a hello-world container.
  • Kubernetes cluster healthy: All nodes are Ready and core system pods are Running.
  • VM reachable: The VM reports boot complete and responds through the tenant bastion path.

Expected result

The lab reaches Healthy state for Docker running, Kubernetes cluster healthy, VM reachable.

Reset policy: Student can reset to the last clean snapshot; instructor can force reset from admin view. Teardown policy: Automatic teardown at TTL expiry with manual instructor override for cohorts.
