使用docker-machine设置Swarm的麻烦

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？

回答：

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：

#=========================
# 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

列出群成员

$ 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
ID                         NAME    IMAGE  NODE   DESIRED STATE  CURRENT STATE           ERROR
