With Docker Compose
This example contains everything needed to get a Next.js development and production environment up and running with Docker Compose.
Benefits of Docker Compose
- Develop locally without Node.js or TypeScript installed ✨
- Easy to run, consistent development environment across macOS, Windows, and Linux teams
- Run multiple Next.js apps, databases, and other microservices in a single deployment
- Multistage builds combined with Output Standalone outputs up to 85% smaller apps (Approximately 110 MB compared to 1 GB with create-next-app)
- Easy configuration with YAML files
How to use
Execute create-next-app with npm, Yarn, or pnpm to bootstrap the example:
npx create-next-app --example with-docker-compose with-docker-compose-app
yarn create next-app --example with-docker-compose with-docker-compose-app
pnpm create next-app --example with-docker-compose with-docker-compose-app
Optionally, after the installation is complete:
- Run
cd next-app, then runnpm installoryarn installorpnpm installto generate a lockfile.
It is recommended to commit a lockfile to version control. Although the example will work without one, build errors are more likely to occur when using the latest version of all dependencies. This way, we're always using a known good configuration to develop and run in production.
Prerequisites
Install Docker Desktop for Mac, Windows, or Linux. Docker Desktop includes Docker Compose as part of the installation.
Development
First, run the development server:
# Create a network, which allows containers to communicate
# with each other, by using their container name as a hostname
docker network create my_network
# Build dev
docker compose -f compose.dev.yaml build
# Up dev
docker compose -f compose.dev.yaml up
Open http://localhost:3000 with your browser to see the result.
You can start editing the page by modifying pages/index.tsx. The page auto-updates as you edit the file.
Production
Multistage builds are highly recommended in production. Combined with the Next Output Standalone feature, only node_modules files required for production are copied into the final Docker image.
First, run the production server (Final image approximately 110 MB).
# Create a network, which allows containers to communicate
# with each other, by using their container name as a hostname
docker network create my_network
# Build prod
docker compose -f compose.prod.yaml build
# Up prod in detached mode
docker compose -f compose.prod.yaml up -d
Alternatively, run the production server without multistage builds (Final image approximately 1 GB).
# Create a network, which allows containers to communicate
# with each other, by using their container name as a hostname
docker network create my_network
# Build prod without multistage
docker compose -f compose.prod-without-multistage.yaml build
# Up prod without multistage in detached mode
docker compose -f compose.prod-without-multistage.yaml up -d
Open http://localhost:3000.
Useful commands
# Stop all running containers
docker kill $(docker ps -aq) && docker rm $(docker ps -aq)
# Free space
docker system prune -af --volumes
