This docker-compose.yml file defines two services, web and node, to create a simple web application.
This service uses the nginx:alpine image and exposes port 80. It mounts the host directory ./ to /usr/share/nginx/html to serve static files.
This service uses the node:alpine image and mounts the host directory ./ to /app. It sets the working directory to /app and runs npm install to install dependencies.
The two services work together to run a Node.js application. The web service handles the HTTP requests and serves static files, while the node service runs the actual application.
To start the containers, run:
docker-compose up
This will pull the images if needed, build the containers, and start the services based on the docker-compose.yml file.
The application can be accessed on http://localhost when the containers are running.
Code changes made on the host should be immediately reflected in the containers.
To stop the services, run:
docker-compose down
This stops and removes the containers.
