Default Addons

[etenzy]

I've noticed that certain addons are being installed even though I haven't explicitly activated them.
I mean, it's great that ccm-hetzner, csi-hetzner, cni-canal, machinecontroller and metrics-server are automatically installed when the Hetzner provider is used, but unfortunately I couldn't find anything about it in the documentation.

Is there something like a default addon matrix?

{
  "kubeone": {
    "major": "1",
    "minor": "4",
    "gitVersion": "1.4.0",
    "gitCommit": "24a432834629b860257e4f3975ec223bc85a0c2f",
    "gitTreeState": "",
    "buildDate": "2022-02-16T11:04:51Z",
    "goVersion": "go1.17.5",
    "compiler": "gc",
    "platform": "darwin/arm64"
  },
  "machine_controller": {
    "major": "1",
    "minor": "43",
    "gitVersion": "v1.43.0",
    "gitCommit": "",
    "gitTreeState": "",
    "buildDate": "",
    "goVersion": "",
    "compiler": "",
    "platform": "linux/amd64"
  }
}

Do you mean the matrix that will display under which provider which addons will be user? No, I don't think we have such info. The thing is, some addons are installed conditionally but that doesn't depend in the provider. For example machine-controller addons is regulated by the API field rather then provider.
