* When a worker managed instance group's (MIG) instance template
changes (including machine type, disk size, or Butane snippets
but excluding new AMIs), use Google Cloud's rolling update features
to ensure instances match declared state
* Ignore new AMIs since Fedora CoreOS and Flatcar Linux nodes
already auto-update and reboot themselves
* Rolling updates will create surge instances, wait for health
checks, then delete old instances (0 unavilable instances)
* Instances are replaced to ensure new Ignition/Butane snippets
are respected
* Add managed instance group autohealing (i.e. health checks) to
ensure new instances' Kubelet is running
Renames
* Name apiserver and kubelet health checks consistently
* Rename MIG from `${var.name}-worker-group` to `${var.name}-worker`

Typhoon 
Typhoon is a minimal and free Kubernetes distribution.
- Minimal, stable base Kubernetes distribution
- Declarative infrastructure and configuration
- Free (freedom and cost) and privacy-respecting
- Practical for labs, datacenters, and clouds
Typhoon distributes upstream Kubernetes, architectural conventions, and cluster addons, much like a GNU/Linux distribution provides the Linux kernel and userspace components.
Features 
- Kubernetes v1.24.3 (upstream)
- Single or multi-master, Calico or Cilium or flannel networking
- On-cluster etcd with TLS, RBAC-enabled, network policy, SELinux enforcing
- Advanced features like worker pools, preemptible workers, and snippets customization
- Ready for Ingress, Prometheus, Grafana, CSI, and other optional addons
