This is an example repo that can be used by the new Ansible Automation Platform containerized installer postinstall feature. It takes a configuration-as-code approach to configuring AAP, using Ansible collections such as infra.controller_configuration and infra.ah_configuration.
Note that the postinstall feature uses the ansible.builtin.include_vars module with the dir argument to recursively include all files in the repo ending in ".yml" and ".yaml". This means that the only YAML files in a postinstall repo should be Ansible variable files. Any other YAML files such as playbooks will result in an error from the postinstall feature.
