 2. **Exposed Fleet UI** — `make port-forward` on port 8585 (+ ingress `fleet.localhost`)
 3. **`fleet prepare db`** — Handled by `autoApplySQLMigrations: true` in the Fleet Helm chart

+## Container Registry

+The CI pipeline mirrors the FleetDM image to the Gitea container registry on every release.

+```bash
+# Pull the latest mirrored image
+docker pull git.produktor.io/eslider/flamingo-tech-test:latest
+
+# Pull a specific app version
+docker pull git.produktor.io/eslider/flamingo-tech-test:4.80.1
