Answer 1

This issue is not a docker problem.

Add --host=0.0.0.0 to your webpack command.

You need to connect to your page like this:

http://host:port/webpack-dev-server/index.html

Look to the iframe mode

Answer 2

You need to make sure:

• you docker container has mapped the EXPOSE'd port to a host port

  docker run -p x:y 
  

• your VM (if you are using docker machine with a VM) has forwarded that mapped port to the actual host (the host of the VM).
