Hi there,
on my macbook pro (OS Big Sur / Darwin 20.3.0) I am trying to setup the erlang observer on an elixir app running in a local docker container.
On container shell I can successfully run:
iex --name myserver@127.0.0.1 --cookie mycookie -S mix phx.server
and even:
iex --name someproc@127.0.0.1 --cookie mycookie -e "Node.connect(:'myserver@127.0.0.1')" -S mix run --no-start
The nodes can successfully see each other.
The container remaps the EPMD port from 4369 to 43691 and I’d like to launch a local shell like this:
iex --name user@127.0.0.1 --cookie mycookie -e "Node.connect(:'myserver@127.0.0.1')" -S mix run --no-start
but even if the repl starts, the Node.connect / Node.ping to myserver@127.0.0.1 fails.
The most complete guide I’ve found in order to accomplish this goal is here, but I don’t know if - following that - it is correct to use 127.0.0.1 as REMOTE_HOST and even trying I cannot reach in the new shell the remote process.
Any clues/suggestions?
Thank you
Carlo
