Instead of showing kubenet and kuberouter with
Kubernetes 1.19, we now start with Kubernetes
1.28 (or whatever is the latest version) along
with containerd and CNI.
Break out kubernetes package installation and kubeadm invocation
to two different steps, so that we can install kubernetes packages
without setting up the cluster (for the new DMUC labs).
We now go from 1.22 to 1.23.
Updating to 1.22 was necessary because Kubernetes 1.27
deprecated kubeadm config v1beta2, which forced us to
upgrade to v1beta3, which was only introduced in 1.22.
In other words, our scripts can only install Kubernetes
1.22+ now.
Summary of changes:
- "workshopctl" is now "labctl"
- it can handle deployment of VMs but also of managed
Kubernetes clusters (and therefore, it replaces
the "prepare-tf" directory)
- support for many more providers has been added
Check the README.md, in particular the "directory structure";
it has the most important information.
