# Final project verification evidence
|
|
|
|
Captured on 2026-08-24 from the disposable QEMU and k3d integration labs. The
|
|
commands below expose no credentials and can be rerun before the presentation
|
|
to refresh screenshots or terminal recordings.
|
|
|
|
## Two-node Fedora cluster
|
|
|
|
`scripts/provision/lab.sh check` passed after provisioning, host reboot, node 2
|
|
disconnect/reconnect, and complete deletion/recreation of node 2. At the final
|
|
check both Fedora 44 machines ran k3s `v1.33.4+k3s1` and reported `Ready`:
|
|
|
|
```text
|
|
nereus-node1 Ready control-plane,master 192.168.122.10
|
|
nereus-node2 Ready <none> 192.168.122.11
|
|
```
|
|
|
|
The node-replacement test found and fixed two recovery requirements: remove the
|
|
replacement address from the private SSH known-hosts file, and delete the old
|
|
Kubernetes node identity before the new agent joins. The PostgreSQL local-path
|
|
volume was correctly treated as lost with the deleted VM, recreated empty, and
|
|
reseeded by the load generator.
|
|
|
|
## Live application
|
|
|
|
The final namespace check showed three ready API pods, one ready load-generator
|
|
pod, and one ready PostgreSQL pod. The same-origin Mini PC route returned:
|
|
|
|
```text
|
|
GET / 200
|
|
GET /healthz 200
|
|
GET /readyz 200
|
|
X-Nereus-Version 0.1.0
|
|
GET /api/v1/buoys 42 records
|
|
```
|
|
|
|
The static dashboard stayed available while the cluster API was unavailable
|
|
during node recovery, then recovered without a page reload.
|
|
|
|
## Container evidence
|
|
|
|
The locally inspected `nereus-api:0.1.0` image is 7,815,732 bytes and declares
|
|
numeric non-root user `65532`. The container verification also passed with a
|
|
read-only root filesystem.
|
|
|
|
## Rollback evidence
|
|
|
|
The local k3d lab was destroyed and recreated from scratch. Re-running
|
|
`scripts/k3d/lab.sh up` reconciled the running cluster successfully. The proof
|
|
produced these AnalysisRun results:
|
|
|
|
```text
|
|
probe-746bbb94df-2-pre Successful vector(0.0)
|
|
probe-556d5b659b-3-pre Failed vector(1.0)
|
|
```
|
|
|
|
After the failed analysis, the active Service selector remained on the healthy
|
|
revision `746bbb94df`.
