# Uptime Kuma

Self-hosted uptime/status monitoring dashboard. Monitor websites, servers, and
Docker containers.

## Access
- URL: http://localhost:3001
- Create your admin account on first visit.

## Data
- App data: ./data (mounted to /app/data)
- Mounts the Docker socket (read-only) for container monitoring.

## Reverse proxy
If Caddy is installed, you can expose this via the prompt during install
(see configure_caddy_for_service). Default subdomain: uptime.

## Manage
\`\`\`
cd $UPTIME_DIR
docker compose up -d      # start
docker compose down       # stop
docker compose logs -f    # logs
\`\`\`
