> Do I need to set USERID for project foo, or UID? Does it default to 1000 or the author's UID? Oh, someone has a problem with our project, did they remember to set COMPANY_USERID in their bashrc? Oh, wait, they're using zsh, how do you do that there? Oh, but they followed this other project's readme and that set COMPANY_USERID but not COMPANY_GROUPID...

You set it to the output of id -u and id -g. It's two lines. There are definitely lots of things more complex when dealing with docker than this.

You provide the team with a script containing those two lines and a docker-compose wrapper and you're set.

Of course it would have been better not to have to care about these things, but hey, at least you're not installing and configuring 4-5 services to bootstrap an application.
