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

# 构建master镜像

[root@k8s-m-01 ~/mysql/master]# docker build -t registry.cn-hangzhou.aliyuncs.com/alvinos/mysql-master:v1 .

Sending build context to Docker daemon  3.072kB

Step 1/2 : FROM mysql:5.7

# 构建salve镜像

[root@k8s-m-01 ~/mysql/salve]# docker build -t registry.cn-hangzhou.aliyuncs.com/alvinos/mysql-savle:v1 .

Sending build context to Docker daemon  3.072kB

# 推送镜像到仓库

[root@k8s-m-01 ~/mysql/salve]#  docker login --username=yangyang091022 registry.cn-hangzhou.aliyuncs.com

[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

```
