## Components
|
|
|
|
- **Nginx**: Reverse proxy handling SSL termination and routing to Gitea
|
|
- **Gitea**: Git server application (main service)
|
|
- **PostgreSQL**: Database storing repositories metadata, users, issues
|
|
- **Watchtower**: Monitors Docker Hub for image updates, automatically pulls and restarts containers
|
|
|
|
## Container Communication
|
|
|
|
- All containers in the same Docker network
|
|
- Nginx proxies HTTPS requests to Gitea's internal port 3000
|
|
- Gitea connects to PostgreSQL via container name
|
|
- Watchtower runs on schedule, checking for updates
|
|
- Let's Encrypt certbot renews certificates automatically (via nginx container or separate container)
|
|
|
|
## Data Persistence
|
|
|
|
Docker volumes ensure data survives container restarts:
|
|
- `gitea_data`: Git repositories and uploads
|
|
- `postgres_data`: Database files
