⁠Bind Mounts:

docker run -v "$(pwd):/app" -v feedy:/app/feedback -d -p 3000:80 --rm --name deep zsp10/volumes

• Might cause error, if you don't have node_modules in the host machine, one way to avoid this is by creating an anonymous volume out of the node_modules from the container itself i.e -v app/node_modules
  • docker run -v "$(pwd):/app" -v app/node_modules -v feedy:/app/feedback -d -p 3000:80 --rm --name deep zsp10/volumes

⁠Adding Read-Only property for bind-mount

• "ro" for read-only
