创建网络

创建容器网络

docker network create pxc-network

Bootstrap集群，创建第一个节点

docker run -d \ -e MYSQL_ROOT_PASSWORD=root \ -e CLUSTER_NAME=cluster1 \ --name=node1 \ --net=pxc-network \ percona/percona-xtradb-cluster:5.7

加入第二个节点

docker run -d \ -e MYSQL_ROOT_PASSWORD=root \ -e CLUSTER_NAME=cluster1 \ -e CLUSTER_JOIN=node1 \ --name=node2 \ --net=pxc-network \ percona/percona-xtradb-cluster:5.7

加入第三个节点

docker run -d \ -e MYSQL_ROOT_PASSWORD=root \ -e CLUSTER_NAME=cluster1 \ -e CLUSTER_JOIN=node1 \ --name=node3 \ --net=pxc-network \ percona/percona-xtradb-cluster:5.7
