我正在利用Docker机器来解决一些问题 .
我的电脑是mac，使用Docker for mac . 我用docker-machine创建了2个vm，vm1和vm2，并尝试初始化一个拥有nodes-vm1，vm2和my mac的swarm . 我的步骤如下：
1.创建一个名为"sprinla/cms:latest"的图像和一个docker-compose.yml

version: "3"
services:
  web:
    image: sprinla/cms:latest
    deploy:
      replicas: 1
    ports:
      - "80:80"
    networks:
      - webnet
    command: /data/start.sh
networks:
  webnet:

2.创建2个vms.Here是vm信息：

yuxrdeMBP:~ yuxr$ docker-machine ls  
NAME   ACTIVE   DRIVER       STATE     URL                         SWARM   DOCKER        ERRORS  
vm1    -        virtualbox   Running   tcp://192.168.99.100:2376           v17.12.0-ce  
vm2    -        virtualbox   Running   tcp://192.168.99.101:2376           v17.12.0-ce

我的mac主机上有

  • init swarm：

yuxrdeMBP：~yuxr $ docker swarm init
Swarm初始化：当前节点（uf6rg1v91exlwntlskyj8iim7）现在是一个管理器 .
要将worker添加到此swarm，请运行以下命令：
docker swarm join --token SWMTKN-1-3qb32l84n0s8vl74rj9d6psm7bzdany3piw55ohtrq0q7ly814-c5km5zg3kj9d6vn6vrtt6xxtg 192.168.65.2:2377
要向此群添加管理器，请运行“docker swarm join-token manager”并按照说明操作 .

4加入vm1到swarm，然后出现问题

yuxrdeMBP:~ yuxr$ docker-machine ssh vm1 "docker swarm join --token SWMTKN-1-3qb32l84n0s8vl74rj9d6psm7bzdany3piw55ohtrq0q7ly814-c5km5zg3kj9d6vn6vrtt6xxtg 192.168.65.2:2377"
Error response from daemon: Timeout was reached before node joined. The attempt to join the swarm will continue in the background. Use the "docker info" command to see the current swarm status of your node.
exit status 1

为什么？？？？
mac主机有ip，192.168.99.1，vm1有ip 192.168.99.100，vm2有ip 192.168.99.101，它们在同一个网络中，为什么可以't vm1 nor vm2 join the mac host' s群？

另一个问题：如果我使用vm1作为swarm管理器，在mac主机上运行“docker swarm join”commad，当作为worker加入时，它可以加入但不能使用;当join作为manager时会出错：

yuxrdeMBP:~ yuxr$ docker swarm join --token SWMTKN-1-49w1hd28hs1mtj3sgmd0o3q7n59zgppvd18vs0iwhcnjemzmwb-7mk35zdnaslt1p41gninvwlud 192.168.99.100:2377
Error response from daemon: manager stopped: can't initialize raft node: rpc error: code = Unknown desc = could not connect to prospective new cluster member using its advertised address: rpc error: code = Unavailable desc = grpc: the connection is unavailable

谢谢你帮助我!!!

    Mac主机和Docker for Mac之间没有路由 . 因此，在Mac上，您只能在VM之间设置多节点群，而标准的Docker for Mac无法参与多节点游泳 . 这是对OSX上如何实现网络的限制 .

    见documentation，这是解释 . 另请参阅此issue了解更多背景信息 .
