I think this is a very valuable work and I am happy to participate.

I think we need design some parts,like - AnsibleControlPlane. - AnsibleBootstrap. - ... [KubeadmControlPlane 设计](https://github.com/kubernetes-sigs/cluster-api/blob/main/docs/proposals/20191017-kubeadm-based-control-plane.md) [bootstrap 设计](https://github.com/kubernetes-sigs/cluster-api/blob/main/docs/proposals/20190610-machine-states-preboot-bootstrapping.md)

Cluster-api working group is thinking about In-place upgrades feature. https://github.com/kubernetes-sigs/cluster-api/pull/9559. maybe we need it.

@amshankaran you can close by set args ``` args: [ "-localip", "169.254.20.10,{{ skydns_server }}", "-conf", "/etc/Corefile","-metrics-listen-address", "0", "-upstreamsvc", "kube-dns-upstream" ] ```

OK, I am not able to handle everything skillfully, which has wasted a lot of time. Now you can push my patch via another PR with everything fixed.Thanks ________________________________ From:...

code is https://github.com/kubernetes-sigs/cluster-api-provider-openstack/blob/4ab8b3a34ebc54036f62ff5fdaf1dc39c2fa33ba/controllers/openstackcluster_controller.go#L726-L729 maybe we shoud add some code like this ``` handleUpdateOSCError(openStackCluster, errors.Errorf("failed to reconcile load balancer: %v", err)) ```

But first, we need to confirm that this error is terminal Failure. Under this condition, I can submit a PR. @dulek Therefore, we first need to find someone to confirm...

fine,I will propose a PR to fix it

@dulek Can you help me review this PR? Thank you.
