1|0Docker swarm 实战-部署wordpress

1|1创建一个overlay的网络

docker network create -d overlay demo

docker network ls
NETWORK ID          NAME                DRIVER              SCOPE
feea5ba8507b        bridge              bridge              local
6imq8da3vcwv        demo                overlay             swarm
84e129614ea7        docker_gwbridge     bridge              local
d1b0002bf8c8        host                host                local
dgfigrlal70j        ingress             overlay             swarm
633e169e521c        none                null                local

在swarm集群中，创建一个网络之后并不会立即同步到其他节点中，只有当该网络被某个服务使用时，才会同步过去。

1|2创建一个mysql服务

docker service create --name mysql --env MYSQL_ROOT_PASSWORD=root --env MYSQLDATABASE=wordpress --network=demo --mount type=volume,source=mysql-data,destination=/var/lib/mysql mysql:5.7

ep1vpcjhsevq        mysql               replicated          1/1                 mysql:5.7
