使用docker-machine进行安装Swarm

Question

我在部署本地基于virtualbox的群集时遇到问题 - 我按照官方docker文档中有关使用docker-machine工具设置master/worker节点的说明。我在dockerhub上创建了令牌，并且使用--swarm（和--swarm-master）和--warm-discovery令牌：// XXXX ...迄今为止非常好，两台机器运行，似乎已注册为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 

和设置使用“的eval $（泊坞窗机ENV --swarm群主）”正确的环境价值观后，我可以使用“泊坞窗信息”，说明我有两个节点的状态运行... 但任何尝试运行任何其他码头群swarm命令（码头节点...，码头服务...）我得到“错误响应守护进程：404页未找到”。

我在做什么错？

看起来您正在尝试使用新的swarm mode功能与较旧的docker swarm相比较。

下面的脚本创建了3名管理者和工人2（使用泊坞窗1.12.0）一个HA集群群：

#========================= 
# Creating cluster members 
#========================= 
docker-machine create --driver virtualbox node1 
docker-machine create --driver virtualbox node2 
docker-machine create --driver virtualbox node3 
docker-machine create --driver virtualbox node4 
docker-machine create --driver virtualbox node5 

#=============== 
# Starting swarm 
#=============== 
MANAGER_IP=$(docker-machine ip node1) 

docker-machine ssh node1 docker swarm init --advertise-addr $MANAGER_IP 

#=============== 
# Adding members 
#=============== 
MANAGER_TOKEN=$(docker-machine ssh node1 docker swarm join-token --quiet manager) 
WORKER_TOKEN=$(docker-machine ssh node1 docker swarm join-token --quiet worker) 

docker-machine ssh node2 docker swarm join --token $MANAGER_TOKEN $MANAGER_IP:2377 
docker-machine ssh node3 docker swarm join --token $MANAGER_TOKEN $MANAGER_IP:2377 
docker-machine ssh node4 docker swarm join --token $WORKER_TOKEN $MANAGER_IP:2377 
docker-machine ssh node5 docker swarm join --token $WORKER_TOKEN $MANAGER_IP:2377 

列表中的群组成员

$ docker-machine ssh node1 docker node ls 
ID       HOSTNAME STATUS AVAILABILITY MANAGER STATUS 
4s0mrh2u4sa2p260ung8ipb0m * node1  Ready Active  Leader 
5ra7b8cwarpcpa47p2gq2ecxs node2  Ready Active  Reachable 
66t3pq66ynlvyl3do6lpn9kzb node3  Ready Active   
7k5n1id2q6yncqjbv7l8ec0r5 node5  Ready Active   
833e4ya58hq62epplreyvwtnm node4  Ready Active 

创建服务

$ docker-machine ssh node1 docker service create --name web --replicas=10 -p 30000:80 nginx 

$ docker-machine ssh node1 docker service ps web
