I use Docker mostly when working on software projects and I figured out how to get Erlang’s Dialyzer GUI working in a Docker container.

1. Start a container with X11 forwarding:

   $ docker run -it --rm --net=host -e "DISPLAY" -e "NO_AT_BRIDGE=1" \
   -v "$XAUTHORITY:/root/.Xauthority:rw" elixir bash

2. Build “the recommended minimal PLT for Erlang/OTP”:

   # dialyzer --build_plt --apps erts kernel stdlib mnesia
   Creating PLT /root/.cache/erlang/.dialyzer_plt ...
   ...
   done (warnings were emitted)

3. Start the Dialyzer GUI:

   1. From the command line:

       # dialyzer --gui

   2. From inside an IEx session:

      1. Start the Dialyzer application:

         iex(1)> Application.load(:dialyzer)
         :ok

      2. Start the Dialyzer GUI:

         iex(2)> :dialyzer.gui()

You should now see the Dialyzer GUI.
