Release error: Failed to create cookie file '/.erlang.cookie'
Hi, this is the first time I migrated the release system for a distributed app from Distillery to Elixir releases.
I’m building a docker image containing the release but when I launch it I’m getting this error:
=ERROR REPORT==== 16-Aug-2023::14:04:26.370926 ===
Failed to create cookie file '/.erlang.cookie': eacces
=CRASH REPORT==== 16-Aug-2023::14:04:26.377384 ===
I tried to create a writable /.erlang.cookie file with some contents but it didn’t work.
Creating a release in the past with just Elixir releases has not been a problem, but this time I don’t know how to fix this error.

It seems that the Erlang restringes the location of the erlang.cookie file, it will be created in the $HOME directory.
What happened is that $HOME was set to /
Once I changed it in the Dockerfile, the file could be created and the app booted!
ENV HOME=/app
Thanks you all guys!
