I am having a bit of trouble with magnum on my devstacks openstack install on BARE METAL Ubuntu 18.04. When i try to create a cluster template with kubernetes like this:

magnum cluster-template-create --name k8s-cluster-template --image fedora-atomic --keypair keypair --external-network public --dns-nameserver 8.8.8.8 --flavor cloud.flavor --docker-volume-size 3 --network-driver flannel --coe kubernetes

I get an ERROR: error

debugging gives the following result https://pastebin.com/JLcT4NQP

Taking a bit of that pastebin. It looks like this is the error.

Magnum is trying to reach my openstacks on http://OPENSTACK_IP:9511/v1/clustertemplates but it cant find anything there and gets a 503 error.

How do I solve this? Can I create an endpoint so it does find something or will that not work?

Thanks a lot!
