Dalton Hubble b3c384fbc0 Introduce the component system for managing pre-installed addons
* Previously: Typhoon provisions clusters with kube-system components
like CoreDNS, kube-proxy, and a chosen CNI provider (among flannel,
Calico, or Cilium) pre-installed. This is convenient since clusters
come with "batteries included". But it also means upgrading these
components is generally done in lock-step, by upgrading to a new
Typhoon / Kubernetes release
* It can be valuable to manage these components with a separate
plan/apply process or through automations and deploy systems. For
example, this allows managing CoreDNS separately from the cluster's
lifecycle.
* These "components" will continue to be pre-installed by default,
but a new `components` variable allows them to be disabled and
managed as "addons", components you apply after cluster creation
and manage on a rolling basis. For some of these, we may provide
Terraform modules to aide in managing these components.

```
module "cluster" {
  # defaults
  components = {
    enable = true
    coredns = {
      enable = true
    }
    kube_proxy = {
      enable = true
    }
    # Only the CNI set in var.networking will be installed
    flannel = {
      enable = true
    }
    calico = {
      enable = true
    }
    cilium = {
      enable = true
    }
  }
}
```

An earlier variable `install_container_networking = true/false` has
been removed, since it can now be achieved with this more extensible
and general components mechanism by setting the chosen networking
provider enable field to false.

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 v1.30.1 (upstream)
  • Single or multi-master, Calico or Cilium or flannel networking
  • On-cluster etcd with TLS, RBAC-enabled, network policy
  • Advanced features like snippets customization
  • Ready for Ingress, Prometheus, Grafana, CSI, and other addons
