Hey Guys,
I’m trying to do a blue-green deployment in a local Linux server before deploying for real, but running into an error:
Protocol 'inet_tcp': the name derpy_tools@south-blue seems to be in use by another Erlang node
I copied the _build/prod
to two separate folders and then I tried to start by passing in appropriate ENV variables. Like different PORT
, and different SECRET_KEY_BASE
.
However, I don’t know how to specify the name of the Erlang node.
I tried: --sname blue-server@south-blue
But it didn’t work.
