My goal is to set up a Docker container that automatically restarts a NodeJS server when file changes are detected from the host machine.
I have chosen nodemon to watch the files for changes.
On Linux and Mac environments, nodemon and docker are working flawlessly.
However, when I am in a Windows environment, nodemon doesn't restart the server.
The files are updated on the host machine, and are linked using the volumes parameter in my docker-compose.yml file.
I can see the files have changed when I run docker exec <container-name> cat /path/to/fileChanged.js. This way I know the files are being linked correctly and have been modified in the container.
Is there any reason why nodemon doesn't restart the server for Windows?

Running non-Node code While Nodemon is running, we can manually restart our application. So instead of stopping and restarting Nodemon, we can just type rs and press enter, and Nodemon will restart the server or the running process for us.
nodemon supports local and global configuration files. These are named nodemon. json and can be located in the current working directory or in your home directory. The specificity is as follows, so that a command line argument will always override the config file settings: command line arguments.
Use nodemon --legacy-watch to poll for file changes instead of listening to file system events.
VirtualBox doesn't pass file system events over the vboxfs share to your Linux VM. If you're using Docker for Windows, it would appear HyperV doesn't propagate file system events either.
As a 2021 side note, Docker for Mac/Windows new GRPCfuse file system for mounting local files into the VM should send file system events across now.
2022 note: Looks like Windows/WSL Docker doesn't share FS events to the Linux VM (see comments @Mohamed Mirghani and @Ryan Wheale).

It is simple, according to the doc you must change:
nodemon server.js to:
nodemon --legacy-watch server.js If you love us? You can donate to us via Paypal or buy me a coffee so we can maintain and grow! Thank you!
