Config Manager is a backend service used by the Service Enablement dashboard to enable or disable various Red Hat services on hosts connected through RHC.

Config Manager handles the following actions:

• Retrieves the current configuration (enabled/disabled) of various services supported by Service Enablement
• Updates the current configuration of services
• Maintains a history of configuration changes
• Ensures that newly connected hosts are kept up to date with the latest configuration
• Updates the host's system profile in Inventory with the latest "rhc_config_state" ID

Config Manager has two mechanisms to update a host:

• Via a change in the Service Enablement dashboard
• Via a new rhc connection event from Inventory

Updating a host (all hosts) via the API:

The REST interface can be used to view and update the current configuration for all hosts connected through RHC. It can also be used to view a history of previous configuration changes, and obtain logs related to those changes.

See the OpenAPI Schema for details on interacting with the REST interface.

Config-manager consumes and produces kafka messages based on various events.

In topics:

• platform.inventory.events
• platform.playbook-dispatcher.runs

Out topics:

• platform.inventory.system-profile

Event based workflow:

1. Consume new connection event from inventory
2. If connection is reported via cloud-connector check rhc_state_id in host's system profile
3. If rhc_state_id is out of date apply current state to host
4. Consume run events from playbook-dispatcher
5. If run event is successful write new rhc_state_id to host via the system-profile kafka topic.
