This repo contains (almost) everything needed to get a working metal3 deployment up and running and demo bare metal provisioning.
Short version is that stuff in scripts is executable, scripts/script.sh is the main deploy script that does all the work. If you wanna read it, start at the bottom in the Default function to see what it does if you give it no args. Otherwise it calls whatever function you pass as args.
Stuff in deploy is all the Kube YAML stuff. It's grouped by deployable thing, so ironic, rancher, etc. script.sh does the deploying of those things, which is typically just kustomize build | kubectl apply -f -.
For anything that looks like it's a missing file in the repo, like Secrets, check templates.d, which mirrors the same hierarchy as deploy. Those get rendered from templates.d into deploy using scripts/render-templates.sh.
ipa-patcher has a Dockerfile and script that captures the manual stuff I was doing to patch the busted systemd unit in the IPA initramfs.
The script should work on ANY Ubuntu 22.04 host, since all the hardware-specific stuff is done by Ironic. And the only Ubuntu-specific bits are the parts where it installs packages if they're missing.
