Orchestration
This plugin deploys Heat, the OpenStack Orchestration service.
Note: This feature is currently supported in channel 2023.2 of the openstack snap.
Enabling Orchestration
To enable Orchestration, run the following command:
sunbeam enable orchestration
Use OpenStack CLI to manage orchestation stacks. See the upstream Heat documentation for details.
Disabling Orchestration
To disable Orchestration, run the following command:
sunbeam disable orchestration
This will terminate the application but not remove it from the model. To do that, run the following:
juju remove-application --force --no-wait --no-prompt -m openstack \
heat heat-cfn heat-mysql-router heat-cfn-mysql-router
Usage
Create a Heat stack using the following command:
openstack stack create \
-t https://opendev.org/openstack/heat-templates/raw/branch/master/hot/servers_in_existing_neutron_net.yaml \
--parameter key_name=sunbeam \
--parameter image=ubuntu \
--parameter flavor=m1.tiny \
--parameter public_net_id=external-network \
--parameter private_net_id=demo-network \
--parameter private_subnet_id=demo-subnet \
teststack
The Heat template referred to in the above command creates two servers in network demo-subnet and assigns them floating IP addresses.
