# kubernetes-ha-ansible
- **kubernetes:** v1.14.x、v.15.x
- **etcd:** v3.3.10
- **容器运行时:** docker 18.06.x、18.09.x; containerd
- **系统:** Ubuntu 16.04+、CentOS 7.4+
部署：ansible快速一键部署二进制kubernetes集群，所有二进制组件下载地址都是国内网络达，真正快速一键部署 。
高可用：采用在每个worker节点部署代理的方式，完全兼容各种有网络限制（不能使用VIP）的云环境（例如阿里云）。

# 快速部署
- 复制一份配置文件
根据自己的集群IP地址信息配置`inventory/k8s-cluster/hosts.ini`文件
```
cp -r inventory/k8s-example inventory/k8s-cluster
```
- 测试节点的连通性
```
ansible -i inventory/k8s-cluster/hosts.ini -m ping all
```
- 执行剧本，部署集群
```
ansible-playbook -i inventory/k8s-cluster/hosts.ini deploy.yml
```
- 查看集群信息
```
