Each service can now be run directly with sudo bash <service>.sh on any machine with Docker installed, without needing the full post-install repo. Uses the shared bootstrap pattern from docs/standalone-template.sh. https://claude.ai/code/session_014CCYqVwW6d6f5dw1qRokYt

# 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
|
|
\`\`\`

|
docker compose up -d # start
|
|
docker compose down # stop
|
|
docker compose logs -f # logs
