Hello Everyone,

I installed queens on centos with magnum and I am trying to create a swarm cluster with one muster and one node. The image I used is fedora-atomic 27 update 04

The stack generated end with an error and magnum conductor reports:

I connected to the master node for verifyng if swarm agent is running.

In the cloud init log I found:

1) Seems etcd service is not installed ,

2) the instance required to contact controller on port 5000 (is it correct ?)

Please help me.
