给我写一个部署k8s集群的ansible的role

在这里我给你一个示例的Ansible Role来部署K8s集群：

- name: Deploy K8s Cluster
  hosts: k8s-masters
  become: yes
  vars:
    k8s_version: 1.20.5
    kubeadm_version: 1.20.5-00
  tasks:
  - name: Install kubeadm, kubelet, and kubectl
    apt:
      name:
        - kubeadm={{ kubeadm_version }}
        - kubelet={{ k8s_version }}-00
        - kubectl={{ k8s_version }}-00
      state: present
      update_cache: true
  - name: Initialize K8s Cluster
    command: kubeadm init --kubernetes-version={{ k8s_version }}
    creates: /etc/kubernetes/admin.conf
  - name: Copy K8s Configuration
    copy:
      src: /etc/kubernetes/admin.conf
      dest: /etc/kubernetes/kubeconfig
      owner: root
      group: root
      mode: 0644
  - name: Deploy Networking
    kubectl:
      cmd: apply
      resource:
        - svc
        - deployment
        - replicaset
        - pod
      namespace: kube-system
      src: /etc/kubernetes/manifests
  - name: Join Nodes
    command: kubeadm join --token={{ kubeadm_token }} {{ ansible_host }}
  - name: Deploy Addons
    kubectl:
      cmd: create
      resource:
        - svc
        - deployment
        - replicaset
        - pod
      namespace: kube-system
      src: /etc/kubernetes/addons

这个示例的Ansible Role会在k8s-masters上安装kubeadm, kubelet, kubectl，初始化k8s集群，复制k8s配置，部署网络，加入新节点并部署插件。

请注意，这只是一个示例，您需要根据您自己的环境进行定制。
