lab-docker's Issues

Step 4, init_swarm_google.sh : No healthy node available in the cluster on lab-net network creation

Hi !

I've been at the workshop in mixit but failed in making it work so I thought give it a try home.

I wanted to create a swarm on the google cloud but I can't get it right.
Everything works fine until this command :
docker $(docker-machine config --swarm master) network create --driver overlay lab-net
where the cloud answers :
Error response from daemon: No healthy node available in the cluster

And it is true that the master machine has 0 containers when asking to docker docker $(docker-machine config --swarm master) info.

It seems consul never gets any connection, when I run docker $(docker-machine config kv) logs 6030c9388f8a where 6030c9 points to the consul vm :

==> WARNING: Bootstrap mode enabled! Do not enable unless necessary
==> WARNING: It is highly recommended to set GOMAXPROCS higher than 1
==> Starting raft data migration...

         Node name: 'consul'

    Gossip encrypt: false, RPC-TLS: false, TLS-Incoming: false
             Atlas: <disabled>

==> Log data will now stream in as it occurs:

I can't find any help on creating a swarm with docker-machine in a cloud.

Can you help me somehow please ?
