In the following example, we will setup a new Magnum bay running Docker Swarm as the COE. The Swarm cluster will deploy a simple NGINX web server running on a Docker container and listening on port 80 and 443 as follows:
- Create a new Magnum cluster template to deploy a Swarm cluster:
# magnum cluster-template-create --name coe-swarm-template \ --image-id fedora-latest \ --keypair-id pp_key \ --external-network-id pub-net \ --dns-nameserver 8.8.8.8 \ --flavor-id m1.small \ --docker-volume-size 4 \ --network-driver docker \ --coe swarm
The previous command line assumes the existence of an image fedora_atomic in the Glance image repository, a key-pair named pp_key and an external Neutron network named pub-net ...
