Feature request: Support multiple organizations in GitHub Enterprise and Enterprise Cloud

[jervi]

When starting the Orka GitHub runner, you need to provide the GITHUB_APP_INSTALLATION_ID. This means that it needs an install for every single organization that it needs to run on. Which also means that the scale set is per organization. If we install it, organizations will be competing for resources on our rather small set of nodes.

It would be nice if it was possible to use the same runner for all organizations in GHE/GHEC setups, or alternatively a way to provide a list of allowed installations or orgs.

Hi @jervi Can you tell us a little more about how many apps, repos, and orgs you need to support? Are there dependencies or are the projects independant? Is it something that changes frequently or involves lots of updates? That will help us understand how many GitHub runners you need to maintain with the current setup, and a bit more detail on how you use Orka with your GitHub projects, so we can assess the best path forward.
Thanks!

Hi @jervi -- Just wanted to follow up on the above comment from @jasoncdavis0. Happy to help however we can! :)

Hi! Thanks for your reply and sorry I missed this.
Currently we have 105 organisations in our Github Cloud instance. Far from all of them need to run macOS runners, but it's more than a few. But is shouldn't matter - when running on GitHub Enterprise (including Cloud), I would argue that the expected behaviour should be that Orka runners are available to all orgs that has the GitHub App installed. In other words, the GITHUB_APP_INSTALLATION_ID should be optional for GHE/GHEC setups.

Currently we are running our own Orka controller (written in house) with GitHub Actions. We pre-create images with Xcode and some other common developer tools preinstalled, and then spin up a new ephemeral VM for each Github Action being run. The Xcode version (i.e. the Orka image being used) can be selected by using labels in the GitHub Action (e.g. xcode-16.3 or xcode-latest). Queueing is also implemented in the controller.
