关于 swarm 1) 初始化swarm manager并制定网卡地址 # docker swarm init –advertise-addr 182.48.115.237 2) 删除集群，强制退出需要加–force (针对manager节点). 到各个节点上执行退出集群的命令 # docker node rm swarm-node1 # docker swarm leave –force //manager节点退出集群,需要加–force 3) 查看swarm worker的连接令牌 # docker swarm join-token worker 例如: [root@manager-node ~]# docker swarm init –advertise-addr 182.48.115.237 Swarm initialized: current node (1gi8utvhu4rxy8oxar2g7h6gr) is now a manager. To add a worker to this swarm, run the following command: docke…
