使用docker机器来设置Swarm的麻烦
我在部署本地基于virtualbox的群集时遇到了问题 – 我按照正式的docker文档中有关使用docker-machine工具设置master / worker节点的说明。 我已经在dockerhub上创build了令牌，并且使用了–swarm（和–war-master）和–warm-discovery token：// XXXX …这么好，两台机器运行，看起来好像是Swarm master，工人：
spaceback@brutus:~$ docker-machine ls NAME ACTIVE DRIVER STATE URL SWARM DOCKER ERRORS swarm-master * (swarm) virtualbox Running tcp://192.168.99.100:2376 swarm-master (master) v1.12.0 swarm-node1 - virtualbox Running tcp://192.168.99.101:2376 swarm-master v1.12.0 spaceback@brutus:~$ docker run --rm swarm list token://[....] 192.168.99.101:2376 192.168.99.100:2376 使用“eval $（docker-machine env – swarm-master）”来设置正确的环境值后，我可以使用“docker info”获得状态，指出我有两个节点正在运行…但是任何尝试运行任何其他docker群swarm命令（docker节点，docker服务…）我得到“错误响应守护进程：404页未find”。
我究竟做错了什么？
看起来你正试图对旧的docker群使用新的群模式特征。
以下脚本创build一个包含3个pipe理员和2个工作人员（使用Docker 1.12.0）的HA Swarm集群：
