## Documentation

# Deploy and Host Davis Calendars and Contacts on Railway

CalDAV and CardDAV with a protected administration dashboard.

**Draft status:** Configuration and upstream documentation reviewed. Container startup, Railway application workflows, restart behavior, backup restoration and costs remain unverified.

## About Hosting

CalDAV and CardDAV with a protected administration dashboard.

| Service | Role | Persistent path |
| --- | --- | --- |
| `mariadb` | Private application or dependency | `/var/lib/mysql` |
| `davis` | Public application | `None` |

## Why Deploy

Run this application in your own Railway project, with explicit configuration and storage under your control.

## Common Use Cases

- Synchronize calendars through CalDAV.
- Maintain contacts using standard CardDAV clients.

## Dependencies for Davis Calendars and Contacts

### Deployment Dependencies

The application images are pinned by registry digest. Database services, when included, stay on the private network. One replica is supported for each volume-backed service.

## First use

Open the application HTTPS domain and follow the native authentication steps below.

Open the public application and log in as admin with davis.ADMIN_PASSWORD.
Create regular DAV users in the dashboard; use those credentials for calendar/contact clients.

## Scope and limitations

- Unpublished draft; container startup, application workflows and recovery are not runtime-verified.
- Uses native admin and DAV credentials instead of the owner gateway so standard DAV clients work.
- WebDAV file storage and public calendars are disabled. Create ordinary calendar/contact users in the admin interface.

## Acceptance checks before use

- Verify the admin dashboard and DAV endpoint reject unauthenticated access.
- Verify incorrect credentials are rejected, create a user, and sync a test event and contact with a DAV client.
- Back up all persistent storage; restart and restore a copy before production use.
- Confirm generated credentials are distinct on a second fresh deployment.
- Back up every listed persistent path and database, then restore into a separate test project.
- Measure Railway usage with representative data and workload before estimating operating costs.

## Backups and upgrades

Back up databases, file volumes, encryption keys and configuration together. Keep a copy outside the running project. Review upstream migration notes before changing a digest; rollback can require restoring a compatible database and files, not just selecting an older image.
