Orchestration

This feature 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.
