This Ansible playbook is designed to install patches and updates across Red Hat Enterprise Linux (RHEL) systems. It dynamically adjusts to RHEL versions 7, 8, and 9 and configures repositories, installs necessary packages, and applies updates.
The playbook uses variables such as survey_hostname or survey_hosts to target hosts for patch management. Ensure your Job Template in the Ansible Controller is handling these variables.
- Dynamic Repository Management: Enables appropriate repositories based on the RHEL version detected on the target machine.
- Prerequisite Installation: Installs necessary utilities like
yum-utils. - Selective Package Updates: Supports excluding specific packages from updates and can re-include them later if needed.
- EPEL Updates: Handles updates for packages from the EPEL repository.
- Cleanup Operations: Removes unused dependencies.
- System Reboot Management: Checks if a reboot is necessary after updates and performs it if required.
Normally used as a scheduled job template in the Ansible Controller.
- survey_hostname or survey_hosts (Required): Specifies the target hosts for patching.
- exclude_packages (Optional): List of packages to exclude from updates.
