> master节点和slave节点
1、构建镜像
```bash
# 配置master /etc/mysql/my.cnf
[root@k8s-m-01 ~]# mkdir -pv /root/mysql/master
[root@k8s-m-01 ~]# cd /root/mysql/master
[root@k8s-m-01 ~]# vim Dockerfile
FROM mysql:5.7
ADD my.cnf /etc/mysql/my.cnf
[root@k8s-m-01 ~]# vim my.cnf
[mysql]
socket=/var/lib/mysql/mysql.sock
[mysqld]
user=mysql
port=3306
binlog_format=mixed
log_bin=mysql-bin
socket=/var/lib/mysql/mysql.sock
server_id=1
sync_binlog=1
log-slave-updates=on
# 配置savle /etc/mysql/my.cnf
[root@k8s-m-01 ~]# mkdir -pv /root/mysql/savle
[root@k8s-m-01 ~]# cd /root/mysql/savle
[root@k8s-m-01 ~]# vim Dockerfile
FROM mysql:5.7
ADD my.cnf /etc/mysql/my.cnf
[root@k8s-m-01 ~]# vim my.cnf
[mysql]
socket=/var/lib/mysql/mysql.sock
[mysqld]
user=mysql
port=3306
binlog_format=mixed
log_bin=mysql-bin
socket=/var/lib/mysql/mysql.sock
server_id=2
read-only=1
# 创建镜像仓库
在阿里云镜像仓库中创建mysql-master和mysql-savle两个仓库
# 构建镜像

[root@k8s-m-01 ~/mysql/salve]# docker push registry.cn-hangzhou.aliyuncs.com/alvinos/mysql-master:v1
[root@k8s-m-01 ~/mysql/salve]# docker push registry.cn-hangzhou.aliyuncs.com/alvinos/mysql-salve:v1
```
2、配置master节点
```bash
# 部署master节点
# 创建master节点主从复制用户
```
