Hi @BrennenMM7. Thanks for your PR.

I'm waiting for a kubernetes-sigs member to verify that this patch is reasonable to test. If it is, they should reply with /ok-to-test on its own line. Until that is done, I will not automatically test new commits in this PR, but the usual testing commands by org members will still work. Regular contributors should join the org to skip this step.

Once the patch is verified, the new status will be reflected by the ok-to-test label.

I understand the commands that are listed here.

@BrennenMM7: Cannot trigger testing until a trusted user reviews the PR and leaves an /ok-to-test message.

I've had a chat during the CAPG meeting with @BrennenMM7.

@BrennenMM7 and team would like some thoughts on the overall design of the API, mainly from maintainers.
Once that is agreed on they can write E2Es to prove this works and ensure regression checks on future changes.

Would we be able to avoid having to watch KubeadmConfig? This would prevent anyone enabling MachinePool from selecting the bootstrap provider of their choice and force them to use Kubeadm. This is something we've realized happens in CAPZ and there's an open issue to address this. Other providers, like CAPA, don't have this dependency on Kubeadm.

A great point @salasberryfin 👍

+1, thanks for catching this!

This is a great point, I'd love to abstract the mechanism away from the kubeadm bootstrap provider lock-in. Any idea how we'd enqueue a reconcile from a token rotation when two different bootstrap providers are being utilized 🤔

Hey @BrennenMM7. We discussed previously the fact that we do not want to create a Kubeadm dependency, which was an issue with other providers too. I think we can do something similar to what CAPZ did here which decouples the MachinePool reconciler from Kubeadm. What do you think?

BrennenMM7 · 2024-07-08T16:58:21Z

@salasberryfin 👋 Yeah this looks good, I can easily port my changes to support this, I'll update and rebase this PR this week.
