Scenario
A disposable Ceph cluster is required. The lab is one exercise in a continuous series of ceph labs that build up to the capstone.
Topology
flowchart TD
A[Operator workstation] --> B[cephadm]
B --> C[Ceph cluster
+ MON/MGR/OSDs]
C --> D[Application]
D --> E[Backup target]Requirements
- Hardware: 90 minute session; 4+ nested VMs or bare-metal hosts.
- Software: cephadm-compatible Linux (Ubuntu 24.04, Debian 12, Rocky 9).
- Network access: bond or LACP; cluster and public networks.
- Time / DNS: configured and verified.
Tasks
The student executes the lab procedure end to end, recording evidence.
Validation
The student runs the validation commands and confirms the expected outcome.
Expected Outcome
The student has demonstrated the competency in a disposable cluster.
Troubleshooting
Common lab failures (network, time, podman, cephx) and how to recover are documented in the upstream Ceph documentation.
Cleanup
# Tear down the cluster
cephadm bootstrap --uninstallProduction notes
Where this lab differs from a permanent install (time, hardware fidelity, capacity) is documented.
What You Learned
The lab maps to one or more of the published learning outcomes for the Ceph course.
