To edit inventory file parameters to specify a supported installation scenario, see Inventory file examples based on installation scenarios in the Red Hat Ansible Automation Platform Installation Guide.

9.1. Standalone automation controller with a database on the same node, or a non-installer managed database

This scenario includes installation of automation controller, including the web frontend, REST API backend, and database on a single machine. It installs PostgreSQL, and configures the automation controller to use that as its database. This is considered the standard automation controller installation scenario.

9.2. Standalone automation controller with an external managed database

This scenario includes installation of the automation controller server on a single machine and configures communication with a remote PostgreSQL instance as its database. This remote PostgreSQL can be a server you manage, or can be provided by a cloud service such as Amazon RDS.

9.3. Standalone automation hub with a database on the same node, or a non-installer managed database

This scenario includes installation of automation hub, including the web frontend, REST API backend, and database on a single machine. It installs PostgreSQL, and configures the automation hub to use that as its database.

9.4. Standalone automation hub with an external managed database

This scenario includes installation of the automation hub server on a single machine, and installs a remote PostgreSQL database, managed by the Red Hat Ansible Automation Platform installer.

9.5. Platform installation with a database on the automation controller node, or non-installer managed database

This scenario includes installation of automation controller and automation hub with a database on the automation controller node, or a non-installer managed database.

9.6. Platform installation with an external managed database

This scenario includes installation of automation controller and automation hub and configures communication with a remote PostgreSQL instance as its database. This remote PostgreSQL can be a server you manage, or can be provided by a cloud service such as Amazon RDS.

9.7. Multi-machine cluster installation with an external managed database

This scenario includes installation of multiple automation controller nodes and an automation hub instance and configures communication with a remote PostgreSQL instance as its database. This remote PostgreSQL can be a server you manage, or can be provided by a cloud service such as Amazon RDS. In this scenario, all automation controller are active and can execute jobs, and any node can receive HTTP requests.

Note
  • Running in a cluster setup requires any database that automation controller uses to be external—​PostgreSQL must be installed on a machine that is not one of the primary or secondary tower nodes. When in a redundant setup, the remote PostgreSQL version requirements is PostgreSQL 13.

    • See Clustering for more information on configuring a clustered setup.
  • Provide a reachable IP address for the [automationhub] host to ensure users can sync content from Private Automation Hub from a different node.
