编写一段代码，实现使用ansible部署kubernetes

下面是一段使用Ansible部署Kubernetes的代码示例：

---
- name: Deploy Kubernetes Cluster
  hosts: k8s-master
  become: yes
  vars:
    k8s_version: 1.21.0
    calico_version: 3.16.6
    etcd_version: 3.4.13
  tasks:
  - name: Install Docker
    package:
      name: docker-ce
      state: present

  - name: Install Ansible
    package:
      name: ansible
      state: present

  - name: Install kubeadm, kubelet, and kubectl
    shell: |
      apt-get update && apt-get install -y apt-transport-https curl
      curl -s https://packages.cloud.google.com/apt/doc/apt-key.gpg | apt-key add -
      echo "deb https://apt.kubernetes.io/ kubernetes-xenial main" | tee -a /etc/apt/sources.list.d/kubernetes.list
      apt-get update
      apt-get install -y kubeadm={{ k8s_version }}-00 kubelet={{ k8s_version }}-00 kubectl={{ k8s_version }}-00

  - name: Initialize kubeadm
    shell: kubeadm init --pod-network-cidr=192.168.0.0/16

  - name: Setup kubectl config
    shell: |
      mkdir -p $HOME/.kube
      cp -i /etc/kubernetes/admin.conf $HOME/.kube/config
      chown $(id -u):$(id -g) $HOME/.kube/config

  - name: Deploy Calico network plugin
    shell: |
      kubectl apply -f https://docs.projectcalico.org/{{ calico_version }}/manifests/calico.yaml

  - name: Check the cluster status
    shell: kubectl get nodes

该代码段实现了以下功能：

1. 安装Docker和Ansible
2. 安装Kubernetes的kubeadm, kubelet和kubectl
3. 使用kubeadm进行初始化
4. 设置kubectl的配置文件
5. 部署Calico网络插件
6. 检查集群状态。

请注意，这仅是一个示例代码，可能需要根据实际情况进行修改。
