+- add support for Ubuntu 22.04

 ## 21.0.0+1.27.5
 
 - **BREAKING**: `meta/main.yml`: change role_name from `kubernetes-controller` to `kubernetes_controller`. This is a requirement since quite some time for Ansible Galaxy. But the requirement was introduced after this role already existed for quite some time. So please update the name of the role in your playbook accordingly!

README.md

@@ -13,6 +13,12 @@ Requirements
 
 This role requires that you already created some certificates for Kubernetes API server (see [Kubernetes the not so hard way with Ansible - Certificate authority (CA)](https://www.tauceti.blog/post/kubernetes-the-not-so-hard-way-with-ansible-certificate-authority/)). The role copies the certificates from `k8s_ca_conf_directory` to the destination host. You should also setup a fully meshed VPN with e.g. WireGuard (see [Kubernetes the not so hard way with Ansible - WireGuard](https://www.tauceti.blog/post/kubernetes-the-not-so-hard-way-with-ansible-wireguard/)) and of course an etcd cluster (see [Kubernetes the not so hard way with Ansible - etcd cluster](https://www.tauceti.blog/post/kubernetes-the-not-so-hard-way-with-ansible-etcd/))
 
+Supported OS
+------------

+- Ubuntu 20.04 (Focal Fossa)
+- Ubuntu 22.04 (Jammy Jellyfish)

+Testing
+-------
+
+This role has a small test setup that is created using [Molecule](https://github.com/ansible-community/molecule), libvirt (vagrant-libvirt) and QEMU/KVM. Please see my blog post [Testing Ansible roles with Molecule, libvirt (vagrant-libvirt) and QEMU/KVM](https://www.tauceti.blog/posts/testing-ansible-roles-with-molecule-libvirt-vagrant-qemu-kvm/) how to setup. The test configuration is [here](https://github.com/githubixx/ansible-role-kubernetes-controller/tree/master/molecule/default).
+
+Afterwards Molecule can be executed:
+
+```bash
+molecule converge
+```
+
+This will setup a few virtual machines (VM) with supported Ubuntu OS and installs an Kubernetes cluster but without the worker nodes (so no nodes with `kube-proxy` and `kubelet` installed). A small verification step is also included:
+
+```bash
+molecule verify
+```
+
+To clean up run
+
+```bash
+molecule destroy
+```
