Uninstalling containerized {PlatformNameShort}

Uninstall your {ContainerBase} of {PlatformNameShort}.

Prerequisites

You have done the following:

• Logged in to the {RHEL} host as your dedicated non-root user.

Procedure

• If you intend to reinstall {PlatformNameShort} and want to use the preserved databases, you must collect the existing 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

• For more information about the *_secret_key variables, see Inventory file variables.

• 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
