Patchi

This is a minimal role to automate security updates to linux servers (OS Patching).

Role Variables

The default varibales are defined in defaults/main.yml.

Features

1. Support for all or selective upgrades.
2. Prompt for confirmation.
3. Produce log trail for the update operation result.
4. Rollback history (based on yum/dnf history).

Dependencies

RHEL/Oracle Linux.

Example Playbook

Install the role:

- name: abarrak.patchi

Apply patching to all only-security available updates:

- hosts: dev,prod
  become: true
  roles:
  - { role: abarrak.patchi, update_security: true }

Apply patching to specific set of packages (with versions optionally, defaults to latest):

- hosts: all
  roles:
  - role: abarrak.patchi
    vars:
      package_list:
      - { name: httpd, version: 1.22.2 }
      - { name: expat }

Apply patching to all available updates (everything):

- hosts: dev
  roles:
  - { role: abarrak.patchi, update_all: true }

Note: In case any upgrade fails, import the rollback tasks and run it. It will revert the last yum transaction from the history log.

- hosts: prod
  import_role:
    name: abarrak.patchi
    tasks_from: rollback

Story

The name comes from a nice chocolate shop in KSA. 😋

The idea is to make patching sweet and less tedious!

TODOs

• Rollback support.
• Add (pre, post) hooks to handle custom shutdown/startup for critical services.
• Categorization (support tags).
