= k8s部署单机容器和高可用集群
6+
7+
== 单机容器
8+
进入k8s集群的master节点上，创建名为ivorysql的namespace
9+
```
10+
[root@k8s-master ~]# kubectl create ns ivorysql
11+
```
12+
13+
下载最新docker_library代码
14+
```
15+
[root@k8s-master ~]# git clone https://github.com/IvorySQL/docker_library.git
16+
```
17+
18+
进入单机目录
19+
```
20+
[root@k8s-master ~]# cd docker_library/k8s-cluster/single
21+
[root@k8s-master single]# vim statefulset.yaml #根据个人环境自行修改statefulset中的pvc信息及数据库密码
22+
```
23+
24+
使用statefulset.yaml创建一个单机pod
25+
```
26+
[root@k8s-master single]# kubectl apply -f statefulset.yaml
27+
service/ivorysql-svc created
28+
statefulset.apps/ivorysql created
29+
```
30+
31+
等待pod创建成功
32+
```
