Docker群叠加networking通信
我正在尝试设置一个Docker Swarm，其中容器使用Overlay Network进行通信，但是我可以使其工作
我使用HypriotOS 1.0.0 Linux发行版模拟了使用4个Raspberry Pi 3主板的基础架构，其中包括Docker Engine 1.12.1
Swarm初始化后，进入pipe理器节点
# create one overlay network $ docker network create --driver overlay swarm_network # create first service (foo) $ docker service create --replicas 1 --name foo --network swarm_network resin/rpi-raspbian tail -F -n0 /etc/hosts # create second service (bar) $ docker service create --replicas 1 --name bar --network swarm_network resin/rpi-raspbian tail -F -n0 /etc/hosts # list services $ docker service ls ID NAME REPLICAS IMAGE COMMAND aqhcndcdoaf4 bar 1/1 resin/rpi-raspbian tail -F -n0 /etc/hosts cylg7ws3egx7 foo 1/1 resin/rpi-raspbian tail -F -n0 /etc/hosts # find docker host running foo service $ docker service ps foo ID NAME IMAGE NODE DESIRED STATE CURRENT STATE ERROR ed6z74ncz1zf0dqc7wph5huvk foo.1 resin/rpi-raspbian swarm-2 Running Running about an hour ago ssh进入swarm-2节点

我无法ping我的服务我做错了什么？
我已经开始这个问题，因为我试图在docker群上运行NSQ，我认为我的问题与覆盖networking有关！
这是最初的问题NSQ Docker Swarm
尝试像这样重新创buildnetworking： docker network create -d overlay --attachable ${NAme}
