Docker Compose — Home Server

Services

Container	Image	Purpose
duckdns	lscr.io/linuxserver/duckdns	Dynamic DNS — keeps *.duckdns.org pointed at the home IP
homeassistant	homeassistant/home-assistant	Home automation, reachable at :8123
timemachine	mbentley/timemachine:smb	Time Machine backup server over SMB
forgejo	codeberg.org/forgejo/forgejo	Self-hosted Git server, web UI at :3000, SSH at :2222

Initial Setup

1. Copy and fill in the environment file:

   cp .env.example .env
   nano .env
   

2. Create the Forgejo data directory if it doesn't exist:

   mkdir -p /home/padriano/projects/forgejo
   

3. Bring the full stack up:

   cd /home/padriano/projects/composer
   docker compose up -d

Common Docker Compose Commands

Stack management

# Start all services (detached)
docker compose up -d

# Stop all services (containers remain)
docker compose stop

# Stop and remove all containers (data volumes are preserved)
docker compose down

# Restart all services
docker compose restart

# Restart a single service
docker compose restart homeassistant

Viewing status and logs

# Show running containers and their status
docker compose ps

# Follow logs for all services
docker compose logs -f

# Follow logs for a single service
docker compose logs -f forgejo

# Show last 50 lines for a service
docker compose logs --tail=50 timemachine

Updating images

# Pull latest images for all services
docker compose pull

# Pull for a single service
docker compose pull forgejo

# Recreate containers that have a newer image
docker compose up -d --pull always

# Recreate a single service after pulling
docker compose up -d --force-recreate forgejo

Inspecting containers

# Open a shell inside a running container
docker exec -it homeassistant bash
docker exec -it forgejo sh        # alpine-based, use sh not bash

# Show resource usage (CPU, RAM, network)
docker stats

# Inspect container configuration
docker inspect forgejo

Service Notes

duckdns

• Config stored at /home/padriano/projects/duckdns/config
• Uses network_mode: host — required for Avahi/mDNS broadcast
• Domains managed: ha-padriano, padrianoha, padriano (all .duckdns.org)

homeassistant

• Config stored at /home/padriano/projects/ha/config
• Web UI: http://192.168.1.116:8123 or http://ha-padriano.duckdns.org
• Uses network_mode: host for device discovery (mDNS, Zigbee, etc.)
• Has a healthcheck — status shows (health: starting) for ~60s on first boot

timemachine

• Backup data stored at /home/padriano/backup/timemachine
• Uses network_mode: host and a fixed hostname: timemachine — the stable hostname prevents macOS from losing the backup destination after container restarts
• On your Mac: System Settings → General → Time Machine → Add Backup Disk

forgejo

• All data (repos, config, SQLite DB) stored at /home/padriano/projects/forgejo
• Backing up this single directory is sufficient for a full restore

First-run setup

Visit http://192.168.1.116:3000 on first start and complete the install wizard:

• Base URL: http://padriano.duckdns.org:3000
• SSH domain: padriano.duckdns.org
• SSH port: 2222

Access

Method	Local network	External (via DuckDNS)
Web UI	http://192.168.1.116:3000	http://padriano.duckdns.org:3000
Git SSH	ssh://git@192.168.1.116:2222	ssh://git@padriano.duckdns.org:2222

For external access, forward these ports on your router to 192.168.1.116:

• TCP 3000 → Forgejo web UI
• TCP 2222 → Forgejo SSH
