SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes scripts (resource) and references (resource) components.

What problem does it solve?

Linux patching and Docker container updates across multiple hosts can be error-prone and time-consuming; this skill automates the process via SSH, supports PatchMon auto-detection, and handles diverse Linux distributions.

Core Features & Use Cases

  • Automated patching: centralizes OS package updates (Ubuntu, Debian, RHEL, AlmaLinux, Rocky, CentOS, Amazon Linux, and SUSE) and optional Docker image updates into a single workflow.
  • PatchMon integration and manual modes: automatically detect hosts needing updates or patch specific hosts on demand.
  • Docker-aware updates: detects Docker presence and manages image pulls and container recreation where applicable; supports dry-run and selective Docker skipping.
  • Secure automation: requires passwordless sudo with restricted commands and SSH key authentication; supports per-host access control and auditing.
  • Quick-start oriented workflows: easy to run with minimal setup and configurable options.

Quick Start

Run the automatic patching workflow with patch-auto.sh to patch all detected hosts from PatchMon.

FAQPage Schema
How do I automate Linux patching across multiple hosts with different distributions?▼

Automate Linux patching across mixed environments by running a central SSH-based workflow that executes package updates for Ubuntu, Debian, RHEL, SUSE, and Amazon Linux hosts from a single script.

Can I update Docker containers and Linux packages at the same time?▼

Yes, you can update Docker containers and Linux packages simultaneously. The patching workflow detects Docker presence, pulls new images, recreates containers, and supports selective Docker skipping.

Do I need passwordless sudo to automate patching over SSH?▼

Yes, passwordless sudo is required to automate patching over SSH. The workflow requires SSH key authentication and restricted sudo command privileges to ensure secure, auditable, and per-host access control.

What is the best way to patch only specific Linux hosts instead of all detected servers?▼

The best way to patch specific Linux hosts is to use the manual per-host workflow mode, which allows you to target individual servers on demand rather than relying on automatic PatchMon-driven detection.

Does this patching workflow support a dry-run mode for testing updates?▼

Yes, the workflow supports a dry-run mode for testing updates. You can safely simulate OS package updates and Docker container recreation across multiple hosts before applying any actual changes.

Can I use PatchMon to automatically detect which Linux hosts need patching?▼

Yes, you can use PatchMon to automatically detect which Linux hosts need patching. The automatic workflow integrates with PatchMon to identify target servers and applies necessary OS and Docker updates.
