我在部署基于本地virtualbox的群集时遇到问题-我已按照官方docker文档中的说明使用docker- machine工具设置主节点/工作节点。我已经在dockerhub上创建了令牌，并将–swarm（和–swarm-master）与–swarm- discovery token：// XXXX一起使用…到目前为止，到目前为止，两台机器都在运行，似乎已注册为Swarm master和工人：
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
然后使用“ eval $（docker-machine env –swarm swarm-master）”设置正确的环境值后，我可以使用“ docker info”获得状态，表明我有两个正在运行的节点，但是尝试运行任何其他docker swarm命令（docker节点…，docker服务…），我得到“来自守护程序的错误响应：找不到404页面”。
我究竟做错了什么？
看来您正在尝试对旧的docker swarm使用新的swarm模式功能。
以下脚本使用3个管理器和2个工作器（使用Docker 1.12.0）创建一个HA Swarm集群：
