Kubernetes搭建MySQL主从集群

前言

文章以mysql8.0版本为基础搭建mysql一主一从集群
开始前需要先从dockerhub拉取mysql:8.0镜像

docker pull mysql:8.0

MySQL master镜像制作

首先在虚机上准备两个目录

[root@k8s-node1 mysql]# ll
total 0
drwxr-xr-x 2 root root 48 Jul 26 21:54 master
drwxr-xr-x 2 root root  6 Jul 26 21:47 slave

使用docker run 命令进入到mysql:8.0镜像中

[root@k8s-node1 master]# docker run --rm -it 192.168.0.101:5000/mysql:8.0 bash
root@80b5b6798bc1:/# ls -l
total 8
