## Site shows fallback content
|
|
|
|
1. Check `docker compose ps` and the backend health status.
|
|
2. Request `http://azionelab.org:8080/api/site/home/` through NGINX.
|
|
3. Inspect `docker compose logs backend postgres`.
|
|
4. Verify `PUBLIC_CMS_API_URL` resolves from the frontend container.
|
|
5. Restart the frontend after recovery so its static page is rebuilt from CMS data.
|
|
|
|
## Wagtail does not start
|
|
|
|
1. Confirm PostgreSQL is healthy.
|
|
2. Check `DATABASE_URL` and allowed hosts without printing secret values in shared logs.
|
|
3. Run `docker compose exec backend python manage.py migrate`.
|
|
4. Review backend logs for a specific migration or configuration error.
|
|
|
|
## Images are missing
|
|
|
|
1. Verify the `media_data` volume is mounted at `/app/media`.
|
|
2. Check `WAGTAILADMIN_BASE_URL` uses a URL reachable by the browser.
|
|
3. Confirm the image still exists in Wagtail and has not been removed from the volume.
|
|
|
|
## A service is unhealthy
|
|
|
|
1. Run `docker compose ps` and inspect `docker compose logs --tail=200 SERVICE`.
|
|
2. For PostgreSQL, check volume capacity and database/user configuration.
|
|
3. For the backend, check `/health/`, migrations, and database connectivity.
|
|
4. For the frontend, request port `4321`, then check the API separately because
|
|
fallback content can mask a CMS outage.
|
|
|
|
## NGINX returns 404 or 502
|
|
|
|
1. Confirm the request host is exactly `azionelab.org`; unknown hosts intentionally
|
|
receive 404.
|
|
2. Run `docker compose exec nginx nginx -t`.
|
|
3. Check `docker compose ps` and verify both backend and frontend are healthy.
|
|
4. Inspect `docker compose logs --tail=200 nginx backend frontend`.
|
|
5. Verify local DNS or `/etc/hosts` maps `azionelab.org` to the proxy address.
|
|
|
|
## Rollback
|
|
|
|
Revert the application commit and rebuild containers. Preserve database/media volumes.
|
|
Before reversing migrations or deleting volumes, make and validate coordinated backups.
