node.js - How to Dockerize a two nodejs applications in one directory

Question

I have a directory structure like this:

I've never used Docker before and want to dockerize my application, the backend folder is a node app with its own package.json and the frontend folder is its own node app with a package.json, normally to launch my app in my dev environment I start it with two separate terminals, I also have a config.js file in the backend and frontend directory with environmental variables.

Answer 1

I would use them in two containers. You can just create a dockerfile in each folder and create a new docker image for each folder/service.

Once you have the images ready you can use e.g. docker-compose to start your containers. Each container can get the same volume to the config file so that each container can read the same config file.
