当Docker Swarm discovery 为file时,应该怎么创建集群


manage:192.168.5.5

node:192.168.5.3192.168.5.4

Docker Swarm discovery 为 file://path/to/file

cluster file content:
192.168.5.3:2375
192.168.5.4:2375


----

manage(192.168.5.5) command:
docker run -d -it -h node-m --name=node-m --restart=always -p 3375:2375 swarm manage -H 0.0.0.0:3375 file:///$(pwd)/cluster:/opt/cluster

node1(192.168.5.3) command:
docker run -d -it -h node-1 --name=node-1 -v $(pwd)/cluster:/tmp/cluster swarm join --addr=192.168.5.3:2375 file:///tmp/cluster

node2(92.168.5.4) command:
docker run -d -it -h node-m --name=node-m -v $(pwd)/cluster:/tmp/cluster --restart=always -p 3375:3375 swarm manage -H 0.0.0.0:3375 file:///tmp/cluster

----

manage(192.168.5.5) command:

docker run --rm -v $(pwd)/cluster:/tmp/cluster swarm list file:///tmp/cluster

其他信息:


swarm version: 1.2.6


docker version: 1.12.6
为什么会出现这个错误呢? "Cannot connect to the Docker daemon at tcp://192.168.5.x:2375. Is the docker daemon running?"
