Setup a swarm - client not registering

General Discussions
1

I’m trying to setup a Swarm with my Mac being the manger and my Fedora server a node agent.

I must admint that the docs are pretty good but has some gaps where I’ve might gone wrong. Here is what I did to setup the swarm

Here is what I did on my Fedora machine (ip=192.168.2.101)

$fedora> docker run --rm swarm create
7b48216c28.....
$fedora> docker run -d swarm join --addr=192.168.2.101:2375 token:7b48216c28....

Next (ip=192.168.2.6)

$Mac> docker run --rm swarm create
5e21aa75384....
$Mac> docker run -d -p 2375:2375 swarm manage token:5e21aa753
$Mac>  docker -H tcp://localhost:2375 info

From this I get the idea that the client (Fedora machine) doesn’t connect. I’ve tried to replace the ip address to the Mac ip but that didn’t help. Any help would be appreciated

Hey…
I see that you have created two swarm clusters. You only need to issue the
docker run --rm swarm create on one machine.
It seems that you have created a swarm token on both of the machines (mac and fedora).
In the mac machine, you can avoid the swarm create command and directly run
docker run -d -p 2375:2375 swarm manage token://<token_generated_from_fedora>
I hope that should work…

Thanks a lot for the reply. Note that I want to have the manger run on my Mac. I still can’t figure out how to get this up and running, so will do this now step-by-step. I’ve posted the follow-up question here Cheers
