Ansible Linux OS patching

Everyone knows that patching packages are not fun. I decided to create an Ansible role that can patch Enterprise Linux ( RHEL ) and other Red Hat derivatives (e.g. CentOS, Rocky, Alma, Fedora ). This role support 3 modes for patching.

  1. Patch all OS packages to the latest version
  2. Apply all security patches
  3. Apply all bugfix patches

Sometimes restart is necessary. In that case, yum-utils (dnf-utils) provide an excellent utility “needs-restarting”. This utility can inform us if a restart is required. If we mix all this we realize that automated patching is not that hard.
