Docker 多主机互联

# 在主节点上

docker swarm init

# 生成token
....

docker swarm join --token SWMTKN-1-2g13vfvyap7rbuvvx966fe6i1sk3fp1xzd8y8qxj48ysk42uea-cbricttyqw5zhlycje1gtysmd 192.168.1.60:2377

#在其它节点添加到集群
docker swarm join --token SWMTKN-1-2g13vfvyap7rbuvvx966fe6i1sk3fp1xzd8y8qxj48ysk42uea-cbricttyqw5zhlycje1gtysmd 192.168.1.60:2377

# 在任意节点创建网络
docker network create -d overlay --attachable net

可能出现错误

Error response from daemon: could not choose an IP address to advertise since this system has multiple addresses on different interfaces (10.0.0.60 on eth0 and 192.168.1.60 on eth1) - specify one with --advertise-addr

这个错误出现在电脑有多个网卡时，原因是docker不知道该选用那个ip作为地址，解决方式很简单，就是在命令后面加上参数 --advertise-addr ip地址
