# 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.
99
+
100
+
# 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.
101

# For the server type, the minimum instance supported is cx23. If you want to use arm64 use cax11; see https://www.hetzner.com/cloud.
102
+
103
+
# 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.
104
+
# 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).
105
+
# You can also rename it (if the count is 0), but do not remove a nodepool from the list.
106
+
107
+
# You can safely add or remove nodepools at the end of each list. That is due to how subnets and IPs get allocated (FILO).
108
+
# The maximum number of nodepools you can create combined for both lists is 50 (see above).
109
+
# 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.
110
+
111
+
# 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.
112
+
# ⚠️ The nodepool names are entirely arbitrary, but all lowercase, no special characters or underscore (dashes are allowed), and they must be unique.
113
+
114

# 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.

# lb_hostname Configuration:
757
+
#
758
+
# Purpose:
759
+
# The lb_hostname setting optimizes communication between services within the Kubernetes cluster
760
+
# when they use domain names instead of direct service names. By associating a domain name directly
761
+
# with the Hetzner Load Balancer, this setting can help reduce potential communication delays.
762
+
#
763
+
# Scenario:
764
+
# If Service B communicates with Service A using a domain (e.g., `a.mycluster.domain.com`) that points
765
+
# to an external Load Balancer, there can be a slowdown in communication.
766
+
#
767
+
# Guidance:
768
+
# - If your internal services use domain names pointing to an external LB, set lb_hostname to a domain
769
+
# like `mycluster.domain.com`.
770
+
# - Create an A record pointing `mycluster.domain.com` to your LB's IP.
771
+
# - Create a CNAME record for `a.mycluster.domain.com` (or xyz.com) pointing to `mycluster.domain.com`.
772
+
#
773
+
# Technical Note:
774
+
# This setting sets the `load-balancer.hetzner.cloud/hostname` in the Hetzner LB definition, suitable for
775
+
# HAProxy, Nginx and Traefik ingress controllers.
776
+
#
777
+
# Recommendation:
778
+
# This setting is optional. If services communicate using direct service names, you can leave this unset.
779
+
# For inter-namespace communication, use `.service_name` as per Kubernetes norms.
780
+
#
781
+
# Example:
782
+
# lb_hostname = "mycluster.domain.com"
783
+
784
+
# You can enable Rancher (installed by Helm behind the scenes) with the following flag, the default is "false".
785
+
# ⚠️ Rancher often doesn't support the latest Kubernetes version. You will need to set initial_k3s_channel to a supported version.
786
+
# When Rancher is enabled, it automatically installs cert-manager too, and it uses rancher's own self-signed certificates.
787
+
# See for options https://ranchermanager.docs.rancher.com/getting-started/installation-and-upgrade/install-upgrade-on-a-kubernetes-cluster#3-choose-your-ssl-configuration
788
+
# The easiest thing is to leave everything as is (using the default rancher self-signed certificate) and put Cloudflare in front of it.
789
+
# As for the number of replicas, by default it is set to the number of control plane nodes.
790
+
# You can customized all of the above by adding a rancher_values variable see at the end of this file in the advanced section (or use rancher_merge_values).
791
+
# After the cluster is deployed, you can always use HelmChartConfig definition to tweak the configuration.
792
+
# IMPORTANT: Rancher's install is quite memory intensive, you will require at least 4GB if RAM, meaning cx23 server type (for your control plane).
793
+
# ALSO, in order for Rancher to successfully deploy, you have to set the "rancher_hostname".
794
+
# enable_rancher = true
795
+
796
+
# If using Rancher you can set the Rancher hostname, it must be unique hostname even if you do not use it.
797
+
# If not pointing the DNS, you can just port-forward locally via kubectl to get access to the dashboard.
798
+
# 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.
799
+
# But if you set this one explicitly, it will have preference over the lb_hostname in rancher settings.
800
+
# rancher_hostname = "rancher.xyz.dev"
801
+
802
+
# When Rancher is deployed, by default is uses the "latest" channel. But this can be customized.
803
+
# The allowed values are "stable" or "latest".
804
+
# rancher_install_channel = "stable"
805
+
806
+
# Finally, you can specify a bootstrap-password for your rancher instance. Minimum 48 characters long!
807
+
# If you leave empty, one will be generated for you.
808
+
# (Can be used by another rancher2 provider to continue setup of rancher outside this module.)
809
+
# rancher_bootstrap_password = ""
810
+
811
+
# Separate from the above Rancher config (only use one or the other). You can import this cluster directly on an
812
+
# an already active Rancher install. By clicking "import cluster" choosing "generic", giving it a name and pasting
813
+
# the cluster registration url below. However, you can also ignore that and apply the url via kubectl as instructed
814
+
# by Rancher in the wizard, and that would register your cluster too.

### ADVANCED - Custom helm values for packages above (search _values if you want to located where those are mentioned upper in this file)
847
+
# ⚠️ 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.
848
+
# Please understand that the indentation is very important, inside the EOTs, as those are proper yaml helm values.
849
+
# We advise you to use the default values, and only change them if you know what you are doing!
850
+
851
+
# You can inline the values here in heredoc-style (as the examples below with the <<EOT to EOT). Please note that the current indentation inside the EOT is important.
852
+
# Or you can create a thepackage-values.yaml file with the content and use it here with the following syntax:
853
+
# thepackage_values = file("thepackage-values.yaml")
854
+
# _values fully replaces the chart values used by the module. _merge_values keeps the defaults (or *_values if set) and overlays your YAML on top.
855
+
856
+
# Cilium, all Cilium helm values can be found at https://github.com/cilium/cilium/blob/master/install/kubernetes/cilium/values.yaml

# Be careful when maintaining your own cilium_values, as the choice of available settings depends on the Cilium version used. See also the cilium_version setting to fix a specific version.
858

# If you want to merge extra values into defaults (or cilium_values), use cilium_merge_values.
