Skill: Docker Compose (Full Stack)
This skill implements step 7 from LOCAL_DEVELOPMENT.md and automates the full-stack Docker Compose flow.
Prerequisites
- Docker Desktop is installed and running.
- Repository dependencies can be installed (
npm install in app/frontend/ and app/backend/).
- Frontend/API source builds are valid.
What This Skill Automates
From section 7, this skill automates:
- Build prerequisites:
- Frontend build with
npx vite build --mode development
- API build with
npm run build in app/backend/
- Stack start:
docker compose up --build -d
- Verification checks:
docker compose ps- API health check (
http://localhost:3001/health)
- DB table count query in
db container
- Logs streaming
- Graceful stop (
docker compose down)
- Fresh reset (
docker compose down -v then recreate)
Automated Setup (Recommended)
Use wrapper entrypoints so the script picks the correct implementation for your OS.
Note for maintainers: docker-compose-local.ps1 and docker-compose-local.sh are preferred user entrypoints. Manage-DockerComposeLocal.ps1 and manage-docker-compose-local.sh are internal implementation scripts called by wrappers.
PowerShell wrapper (recommended on Windows)
Set-Location .github/skills/07.docker-compose-local/scripts
.\docker-compose-local.ps1 -Action start
bash wrapper (recommended on Linux/macOS)
cd .github/skills/07.docker-compose-local/scripts
bash ./docker-compose-local.sh start
Actions
Start full stack (with build prerequisites)
Set-Location .github/skills/07.docker-compose-local/scripts
.\docker-compose-local.ps1 -Action start
cd .github/skills/07.docker-compose-local/scripts
bash ./docker-compose-local.sh start
Start without rebuilding
Set-Location .github/skills/07.docker-compose-local/scripts
.\docker-compose-local.ps1 -Action start -SkipBuild
cd .github/skills/07.docker-compose-local/scripts
bash ./docker-compose-local.sh start --skip-build
Verify stack
Set-Location .github/skills/07.docker-compose-local/scripts
.\docker-compose-local.ps1 -Action verify
cd .github/skills/07.docker-compose-local/scripts
bash ./docker-compose-local.sh verify
Stream logs
Set-Location .github/skills/07.docker-compose-local/scripts
.\docker-compose-local.ps1 -Action logs
cd .github/skills/07.docker-compose-local/scripts
bash ./docker-compose-local.sh logs
Show status only
Set-Location .github/skills/07.docker-compose-local/scripts
.\docker-compose-local.ps1 -Action status
cd .github/skills/07.docker-compose-local/scripts
bash ./docker-compose-local.sh status
Stop stack (preserve data)
Set-Location .github/skills/07.docker-compose-local/scripts
.\docker-compose-local.ps1 -Action stop
cd .github/skills/07.docker-compose-local/scripts
bash ./docker-compose-local.sh stop
Fresh reset (remove volumes and recreate)
Set-Location .github/skills/07.docker-compose-local/scripts
.\docker-compose-local.ps1 -Action reset
cd .github/skills/07.docker-compose-local/scripts
bash ./docker-compose-local.sh reset
Validation
A healthy stack should provide:
- Frontend accessible at
http://localhost:8081 (Docker nginx)
- API health endpoint reachable at
http://localhost:3001/health
- DB container running and queryable
Quick manual checks:
docker compose ps
curl http://localhost:3001/health
docker compose exec db psql -U pronghorn_admin -d pronghorn -c "SELECT count(*) FROM information_schema.tables WHERE table_schema = 'public';"
Troubleshooting
| Problem | Cause | Solution |
|---|
docker compose command fails | Docker Desktop not running | Start Docker Desktop and retry |
| Frontend blank page | Frontend build missing/invalid | Re-run start without --skip-build |
| API health fails | API container not healthy | Check logs: logs action |
| DB query fails | DB container not ready | Wait and retry, then use reset if needed |
| Wrong API URL in frontend | Build used production mode | Ensure build uses --mode development (automated scripts already do this) |
