How Has This Been Tested?

i used:

3 pi 4b+ configured 3 master nodes with HA and keepalived
Ubuntu 24.04 arm64

[masters]
master01 ansible_host=192.168.178.60 rke2_type=server
master02 ansible_host=192.168.178.63 rke2_type=server
master03 ansible_host=192.168.178.62 rke2_type=server

[k8s_cluster:children]
masters

and

sh-5.2$ cat site.yaml 
- name: Deploy RKE2
  hosts: all
  become: yes
  vars:
    rke2_download_kubeconf_path: "/home/dalmine/.config"
    rke2_ha_mode: true
    rke2_api_ip : 192.168.178.240
    rke2_download_kubeconf: true
    disable_kube_proxy: true
    rke2_cni:
       - cilium
  roles:
     - role: lablabs.rke2

Using disalble proxy and ha with api_ip, i also force in the jinja file of cilium another extra parameters where are not in the default/main.yaml

and
default/main.yml
