Uninstall containerized Ansible Automation Platform

Uninstall your container-based installation of Ansible Automation Platform.

Before you begin

You have logged in to the Red Hat Enterprise Linux host as your dedicated non-root user.

Procedure

If you intend to reinstall Ansible Automation Platform and want to use the preserved databases, you must collect the existing secret keys:
1. First, list the available secrets:
```
$ podman secret list
```
2. Next, collect the secret keys by running the following command:
```
$ podman secret inspect --showsecret <secret_key_variable> | jq -r .[].SecretData
```
  For example:
```
$ podman secret inspect --showsecret controller_secret_key | jq -r .[].SecretData
```
Run the uninstall playbook:
```
$ ansible-playbook -i inventory ansible.containerized_installer.uninstall
```
- This stops all systemd units and containers and then deletes all resources used by the containerized installer such as:
  - configuration and data directories and files
  - systemd unit files
  - Podman containers and images
  - RPM packages
- To keep container images, set the container_keep_images parameter to true.
```
$ ansible-playbook -i inventory ansible.containerized_installer.uninstall -e container_keep_images=true
```
- To keep PostgreSQL databases, set the postgresql_keep_databases parameter to true.
```
$ ansible-playbook -i inventory ansible.containerized_installer.uninstall -e postgresql_keep_databases=true
```
