I have a GitHub action that uses an OAuth token to provision a new key and store it in our secrets manager as part of the workflow that provisions systems - the new systems then pull the ephemeral key to onboard themselves as they come up
It can get especially interesting when you do things like have your GitHub runners onboard themselves to Tailscale - at that point you can pretty much fully-provision isolated systems directly from GitHub Actions if you want
