Live reload Node.js dev environment with Docker

Question

I'm trying to work on a dev environment with Node.js and Docker.

I want to be able to:

run my docker container when I boot my computer once and for all;
make changes in my local source code and see the changes without interacting with the docker container (with a mount).

I've tried the Node image and, if I understand correctly, it is not what I'm looking for.

I know how to make the mount point, but I'm missing how the server is supposed to detect the changes and "relaunch" itself.

I'm new to Node.js so if there is a better way to do things, feel free to share.

run my docker container when I boot my computer once and for all;

start containers automatically with the docker daemon or with your process manager

make changes in my local source code and see the changes without interacting with the docker container (with a mount).

You need to mount your dev app folder as a volume

$ docker run --name myapp -v /app/src:/app image/app

and set in your Dockerfile nodeJs

CMD ["nodemon", "-L", "/app"]
