How to develop Erlang Nitrogen apps in Docker

I'm trying to work out an efficient work flow for developing Erlang Nitrogen apps in Docker.

Sans Docker, I would keep two terminals open:

• a bash terminal terminal for making source changes
• a Nitrogen console (erl) for compiling Erlang modules and testing expressions

But I can't find a way to do that in Docker. Attempts to open a second terminal open a new container.

Can some kind soul point the way?

Many thanks,

You can use docker-enter to enter a running container.

For example, you could do

-- Terminal 1 $ docker run -it foo bash container1$ hackhackhack

-- Terminal 2 $ docker ps ... abcd... foo $ docker-enter abcd container1$ hackhackhack
