  # For the control planes, at least three nodes are the minimum for HA. Otherwise, you need to turn off the automatic upgrades (see README).
  # **It must always be an ODD number, never even!** Search the internet for "splitbrain problem with etcd" or see https://rancher.com/docs/k3s/latest/en/installation/ha-embedded/
  # For instance, one is ok (non-HA), two is not ok, and three is ok (becomes HA). It does not matter if they are in the same nodepool or not! So they can be in different locations and of various types.

  # Of course, you can choose any number of nodepools you want, with the location you want. The only constraint on the location is that you need to stay in the same network region, Europe, or the US.
  # For the server type, the minimum instance supported is cpx11 (just a few cents more than cx11); see https://www.hetzner.com/cloud.

  # IMPORTANT: Before you create your cluster, you can do anything you want with the nodepools, but you need at least one of each, control plane and agent.
  # Once the cluster is up and running, you can change nodepool count and even set it to 0 (in the case of the first control-plane nodepool, the minimum is 1).
  # You can also rename it (if the count is 0), but do not remove a nodepool from the list.

  # The only nodepools that are safe to remove from the list are at the end. That is due to how subnets and IPs get allocated (FILO).
  # You can, however, freely add other nodepools at the end of each list if you want. The maximum number of nodepools you can create combined for both lists is 255.
  # Also, before decreasing the count of any nodepools to 0, it's essential to drain and cordon the nodes in question. Otherwise, it will leave your cluster in a bad state.

  # Before initializing the cluster, you can change all parameters and add or remove any nodepools. You need at least one nodepool of each kind, control plane, and agent.
  # The nodepool names are entirely arbitrary, you can choose whatever you want, but no special characters or underscore, and they must be unique; only alphanumeric characters and dashes are allowed.

  # If you want to have a single node cluster, have one control plane nodepools with a count of 1, and one agent nodepool with a count of 0.

  # Please note that changing labels and taints after the first run will have no effect. If needed, you can do that through Kubernetes directly.

  # ⚠️ When choosing ARM cax* server types, for the moment they are only available in fsn1.
  # Muli-architecture clusters are OK for most use cases, as container underlying images tend to be multi-architecture too.

  # You can enable Rancher (installed by Helm behind the scenes) with the following flag, the default is "false".
  # ⚠️ Rancher currently only supports Kubernetes v1.25 and earlier, you will need to set initial_k3s_channel to a supported version: https://github.com/rancher/rancher/issues/41113
  # When Rancher is enabled, it automatically installs cert-manager too, and it uses rancher's own self-signed certificates.
  # See for options https://rancher.com/docs/rancher/v2.0-v2.4/en/installation/resources/advanced/helm2/helm-rancher/#choose-your-ssl-configuration
  # The easiest thing is to leave everything as is (using the default rancher self-signed certificate) and put Cloudflare in front of it.
  # As for the number of replicas, by default it is set to the numbe of control plane nodes.
  # You can customized all of the above by adding a rancher_values variable see at the end of this file in the advanced section.
  # After the cluster is deployed, you can always use HelmChartConfig definition to tweak the configuration.
  # IMPORTANT: Rancher's install is quite memory intensive, you will require at least 4GB if RAM, meaning cx21 server type (for your control plane).
  # ALSO, in order for Rancher to successfully deploy, you have to set the "rancher_hostname".
  # enable_rancher = true

  # If using Rancher you can set the Rancher hostname, it must be unique hostname even if you do not use it.
  # If not pointing the DNS, you can just port-forward locally via kubectl to get access to the dashboard.
  # If you already set the lb_hostname above and are using a Hetzner LB, you do not need to set this one, as it will be used by default.
  # But if you set this one explicitly, it will have preference over the lb_hostname in rancher settings.
  # rancher_hostname = "rancher.xyz.dev"

  # When Rancher is deployed, by default is uses the "latest" channel. But this can be customized.
  # The allowed values are "stable" or "latest".
  # rancher_install_channel = "stable"

  # Finally, you can specify a bootstrap-password for your rancher instance. Minimum 48 characters long!
  # If you leave empty, one will be generated for you.
  # (Can be used by another rancher2 provider to continue setup of rancher outside this module.)
  # rancher_bootstrap_password = ""

  # Separate from the above Rancher config (only use one or the other). You can import this cluster directly on an
  # an already active Rancher install. By clicking "import cluster" choosing "generic", giving it a name and pasting
  # the cluster registration url below. However, you can also ignore that and apply the url via kubectl as instructed
  # by Rancher in the wizard, and that would register your cluster too.
  # More information about the registration can be found here https://rancher.com/docs/rancher/v2.6/en/cluster-provisioning/registered-clusters/
  # rancher_registration_manifest_url = "https://rancher.xyz.dev/v3/import/xxxxxxxxxxxxxxxxxxYYYYYYYYYYYYYYYYYYYzzzzzzzzzzzzzzzzzzzzz.yaml"

  # Extra values that will be passed to the `extra-manifests/kustomization.yaml.tpl` if its present.

  # It is best practice to turn this off, but for backwards compatibility it is set to "true" by default.
  # See https://github.com/kube-hetzner/terraform-hcloud-kube-hetzner/issues/349
  # When "false". The kubeconfig file can instead be created by executing: "terraform output --raw kubeconfig > cluster_kubeconfig.yaml"
  # Always be careful to not commit this file!
  # create_kubeconfig = false

  # Don't create the kustomize backup. This can be helpful for automation.

  ### ADVANCED - Custom helm values for packages above (search _values if you want to located where those are mentioned upper in this file)
  # ⚠️ Inside the _values variable below are examples, up to you to find out the best helm values possible, we do not provide support for customized helm values.
  # Please understand that the indentation is very important, inside the EOTs, as those are proper yaml helm values.
  # We advise you to use the default values, and only change them if you know what you are doing!
