Mern News-Apps with Docker

Containers

• client with React on https://localhost:3000 route
• server with Express on https://localhost:5000 route
• mongo with MongoDB

Usage

You can use docker-compose up -d command to deploy the container, or for every container separately, you can use docker-compose up -d [container_name] client server adminmongo

Get in to container and install more dependecies with docker exec -it server /bin/sh or docker exec -it client /bin/sh and then npm install whatewer.

Get logs from container to check everything is running correctly with docker logs --tail 50 server or docker logs --tail 50 client

Shut down containers with docker-compose down.

If you change Dockerfile rebuild container with docker-compose build server. Container names are client, server, mongo and adminmongo.

Access React app on http://localhost:3000 and test the server on https://localhost:5000/api/message. Generate your own ssl keys and put them in /security folder if you like. Connection to the mongodb is in the /config/dev.js. Access adminmongo on http://localhost:1234.

Additional notes

Tested on Linux Mint 20.1 / Ubuntu 20.04.

For nodemon restart to work there is -L flag in "server": "nodemon -L server.js" in package.json.

For create-react-app to live reload there is CHOKIDAR_USEPOLLING=true environment var in docker-compose.yml.

For mongo volume to work in the Windows VirtualBox shared folder there is volumes: mongodata:.

Note that command in the docker-compose.yml overrides the CMD in the Dockerfile.
