This project is a production Docker setup for a Next.js app.

The Next.js app is launched with PM2 Runtime, which is a Production Process Manager for Node.js applications and is used to keep the app alive forever.

A second container with the NGINX web server is used as a reverse proxy, and to handle HTTP caching.

docker-compose up

NGINX listens on port 80, which is the default HTTP port, so you can just visit http://localhost/

# Build images
docker build --tag nextjs-image .
docker build --tag nginx-image ./nginx

# Create shared network
docker network create my-network

# Run containers
docker run --network my-network --name nextjs-container nextjs-image
docker run --network my-network --link nextjs-container:nextjs --publish 80:80 nginx-image

Next.js container is referenced inside NGINX container as nextjs.

PM2 commands can still be used inside a container with the docker exec command:

docker exec -it <container-id> pm2 monit          # Monitoring CPU/Usage of each process

docker exec -it <container-id> pm2 list           # Listing managed processes

docker exec -it <container-id> pm2 show           # Get more information about a process

docker exec -it <container-id> pm2 reload all     # 0sec downtime reload all applications
