## Publish image for Umbrel
Umbrel installation is most reliable when your app uses a prebuilt image from a registry.
1. Recommended: use the GitHub Action `.github/workflows/publish-nx-webmail-image.yml`.
- For Gitea use `.gitea/workflows/publish-nx-webmail-image.yml`.
- Required Gitea secrets: `GITEA_USERNAME`, `GITEA_TOKEN`.
2. The workflow reads `version` from `nx-webmail/umbrel-app.yml` and publishes:
- `git.weektab.org/nexus/nx-webmail:<version>`
- `git.weektab.org/nexus/nx-webmail:latest`
3. The workflow then pins `nx-webmail/docker-compose.yml` to `tag@sha256:digest` automatically.
4. Manual fallback:
docker buildx build --platform linux/amd64,linux/arm64 -t git.weektab.org/nexus/nx-webmail:1.0.4 --push .
## Umbrel app packaging
This repository is prepared for Umbrel app-store usage.
1. Keep this app in a folder named exactly like the app ID: `nx-webmail`.
2. Keep these files in that folder:
- `docker-compose.yml`
- `umbrel-app.yml`
- `Dockerfile`
- `exports.sh`
3. Ensure your store root contains `umbrel-app-store.yml`.
4. Push the app-store repo to a git host reachable from Umbrel.
## Install from Umbrel UI
1. Open App Store in Umbrel.
2. Use the menu to add a Community App Store.
3. Paste your repository URL.
4. Open your store and install `Webmail`.
Notes:
- Umbrel uses the `app_proxy` service in `docker-compose.yml`.
- Internal app port is `3001`.
- `server` uses a prebuilt registry image (`git.weektab.org/nexus/nx-webmail:1.0.4`).
- If your store prefix changes, update `id` in `umbrel-app.yml` and `APP_HOST` in `docker-compose.yml`.
## Notes
- Frontend calls API on `/api/webmail/*`.
- IMAP/SMTP credentials are provided by user login in UI.
