Docker Development Setup

DevTrack includes Docker support for local development, allowing contributors to get started quickly without manually installing dependencies or configuring environments.

Prerequisites

  • Docker Desktop (Windows/macOS) or Docker Engine (Linux)
  • Docker Compose v2+

Verify installation:

docker --version
docker compose version

Configure Environment Variables

Copy the example environment file:

cp .env.example .env.local

Fill in the required values as described in DEVELOPMENT.md.

Start the Application

Build and start the development container:

docker compose up --build

The application will be available at:

http://localhost:3000

Stop the Application

docker compose down

Hot Reload Support

The project source code is mounted into the container using Docker volumes.

Any changes made to files on your host machine are automatically reflected inside the container, enabling Next.js hot reload during development without rebuilding the image.

Rebuild After Dependency Changes

If you modify package.json or install new dependencies:

docker compose down
docker compose up --build

Troubleshooting

Remove containers and rebuild from scratch:

docker compose down -v
docker compose up --build

View container logs:

docker compose logs -f
