Uses nodemon to listen for server file changes, and restart the express server.
- Install Docker
- Install Docker Compose
Run docker-compose build . - it will
- copy package.json into the container
- copy nodemon.json into the container
- install all production dependencies from the package.json
- copy contents of server/ to the container
- expose port 4000 to the host
- instruct the container to execute
npm starton start up.
Inside the container, express will run on port 80.
Run docker-compose up -d to create and start the container. You can now visit localhost:4000 and see the app running.
The docker-compose is setup to mount the node_modules, so it can crap the nodemon dependency, and run it. Therefor if you haven't run npm install locally in your folder, it will break. I'm trying to see if there can be a better solution for that, so there is no need to run npm install manually.
To watch the console.log from index.js when nodemon executes, then you can run the command docker logs -f <CONTAINER_ID>
