Tutorial: So You Want To Develop a Clust...
summary
Hands‑on guide to building a Cluster API infrastructure provider for Docker that actually provisions each node as a container, creates a container load‑balancer for a 3‑control‑plane setup, and bootstraps nodes with kubeadm bootstrap scripts. Follow the repo scaffolding with Kubebuilder codegen, run locally with Kind and Tilt (live‑reload and delve debugging), implement finalizers, providerID syncing and status patches, and test creation of clusters and DockerMachines; release notes cover making the provider installable via clusterctl.
