Currently each charm defines in the code all the mandatory relations. Instead populate the mandatory relations from chamrcraft.yaml requires relations with optional as False. Charm can define mandatory relations that are not derived from requires relations and they will be appended to the list of mandatory_relations. Barbican and ovn-central charms follows this pattern.

heat-k8s
Description
heat-k8s is an operator to manage the orchestration services heat api, heat api cfn and heat engine on a Kubernetes based environment.
Usage
Deployment
heat-k8s is deployed using below command:
juju deploy heat-k8s heat --trust
Now connect the heat operator to existing database, keystone identity, keystone ops and rabbitmq operators:
juju relate mysql:database heat:database
juju relate keystone:identity-service heat:identity-service
juju relate keystone:identity-ops heat:identity-ops
juju relate rabbitmq:amqp heat:amqp
heat-api-cfn is deployed as separate instance of charm using below command:
juju deploy heat-k8s heat-cfn --trust --config api_service=heat-api-cfn
Configuration
This section covers common and/or important configuration options. See file
config.yaml for the full list of options, along with their descriptions and
default values. See the Juju documentation for details
on configuring applications.
api_service
The api_service option determines whether to act as heat-api service or
heat-api-cfn service. Accepted values are heat-api or heat-api-service
and defaults to heat-api.
Actions
This section covers Juju actions supported by the charm.
Actions allow specific operations to be performed on a per-unit basis. To
display action descriptions run juju actions heat. If the charm is not
deployed then see file actions.yaml.
Relations
heat-k8s requires the following relations:
database: To connect to MySQL
identity-service: To register endpoints in Keystone
identity-ops: To create heat stack domain and users
ingress-internal: To expose service on underlying internal network
ingress-public: To expose service on public network
amqp: To connect to Rabbitmq
OCI Images
The charm by default uses following images:
ghcr.io/canonical/heat-consolidated:2024.1
