nacos集群 docker 有这一篇就够了，详细
之前我们玩的是单机，在这个基础上，我们玩个集群
很简单 ，下面我们开始哈
首先我们有了MySQL 没有的看我其他的博客，或者docker 新来一个
docker pull nacos/nacos-server #拉取nacos镜像
#创建挂载文件路径
mkdir -p /usr/local/nacos/logs1 /usr/local/nacos/logs2 /usr/local/nacos/logs3
mkdir -p /usr/etc/nacos/conf1 /usr/etc/nacos/conf2 /usr/etc/nacos/conf3
docker cp 18fa206c4883:/home/nacos/conf /usr/etc/nacos/conf #复制nacos配置目录到宿主机（或从其他地方复制需要application.properties、cluster.conf）
#创建自定义网络
docker network create --driver bridge --subnet 172.16.0.0/16 self_network
#启动mysql容器
docker create -p 3306:3306 --network self_network --network-alias mysql --name mysql8.0 -e MYSQL_ROOT_PASSWORD=123456 -v /usr/etc/mysql8.0/mysql/conf:/etc/mysql -v /usr/etc/mysql8.0/mysql/logs:/var/log/mysql -v /usr/etc/mysql8.0/mysql/data:/var/lib/mysql -v /usr/etc/mysql8.0/mysql/mysql-files:/var/lib/mysql-files mysql
#创建三个nacos容器

docker network ls
查看docker网卡
docker network rm 网卡id
删除docker网卡
docker network inspect 网卡id
查看docker网卡的相关详细信息
docker logs -f -n 9999 65c48cdba624
