Trying to deploy forge app from CI server

So I’ve got my forge app - I would like to follow proper practices and have my build service deploy it. How?

It looks like forge login:ci was removed in 1.5 ( ).

Trying to login on the build server - I initially got How to use Forge CLI in a CI environment? but once I installed the other prerequisite I got through the keystore but the log in never returns and is just hung. So I’m guessing there is something else going on.

Is it even possible to use Forge CLI on a non-desktop machine?
