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,

LRP

Solution

  • 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
