Docker Swarm nodes stay "Pending"

Docker Engine Swarm
1

I’ve more or less followed https://docs.docker.com/swarm/install-manual/

I have 4 Centos 7 VMs running on VMware, installed Engine on each node at version 1.12.3, build 6b644ec, verified the install by running the hello-world container. Where I later spun up the swarm manager I also spun up consul in a container; specifically, progrium/consul:latest.

I spun up a manager like so:

docker run -d -p 4000:4000 swarm manage -H :4000 --replication --advertise 10.205.45.208:4000 consul://10.205.45.208:8500

And then on each node:

docker run -d swarm join --advertise=[ip of node. you can see em below]:2375 consul://10.205.45.208:8500

When I get information about the manager and nodes in the cluster via:

docker -H 10.205.45.208:4000 info

it returns:

All the nodes are marked “Pending” status, and remain there…

Checking consul’s key-value store, all the nodes are are there.

I’m at a loss. Any thoughts?

Hi @nemonik

I’ve just started with docker swarm, so I may be way off the mark here, but here goes.

I found that link you refer to, and followed some other instructions in the docs with 1.12 and had some issues.

I then did some more digging and found this

Sorry, i know it wont solve your current problem but once I’d found those other docs it all became a little easier for me.

Hope it helps

Thanks @vanderkerkoff I followed these exact directions earlier for what I thought was a non-production swarm and they worked perfectly, but then followed these other directions for a production swarm. But the documentation seemed dorked (i.e., not consistent wit the rest fo the documentation.) I think I’ll stick with what works. Appreciate it.
