## Introduction

PatchMon is an open-source Linux Patch Monitoring Automation Platform designed to simplify centralized patch management across diverse server environments. It enables comprehensive visibility into outdated packages and supports safe automation, all while maintaining a strong security posture through its outbound-only agent model. This means no inbound ports are required on your monitored hosts, significantly reducing the attack surface.

Key features include a customizable dashboard, multi-user accounts with roles and permissions, detailed host and package inventory, and a robust REST API for integrations. PatchMon supports various Linux distributions, including Debian, Ubuntu, CentOS, and Red Hat, making it a versatile tool for system administrators and DevOps teams.

## Installation

PatchMon offers flexible self-hosting options, with Docker being the preferred method for quick setup.

### Docker Installation

For detailed instructions on getting started with Docker, please refer to the [official Docker documentation](https://github.com/PatchMon/PatchMon/blob/main/docker/README.md "PatchMon Docker Documentation" target="_blank").

### Native Install (Ubuntu/Debian)

For advanced users or non-Docker environments, PatchMon can be installed natively on a clean Ubuntu or Debian server. Ensure your server meets the minimum specifications (2 vCPU, 2GB RAM, 15GB Disk).

First, update your system and install `curl`:

bash
# For Debian
apt update -y
apt upgrade -y
apt install curl -y

# For Ubuntu
apt-get update -y
apt-get upgrade -y
apt install curl -y


Then, run the one-line installer script:

bash
curl -fsSL -o setup.sh https://raw.githubusercontent.com/PatchMon/PatchMon/refs/heads/main/setup.sh && chmod +x setup.sh && bash setup.sh


During setup, you will be prompted for details like your domain/IP, SSL preference, and email (if SSL is enabled). After installation, visit `http(s)://<your-domain>` to complete the first-time admin setup.

## Examples

To ensure PatchMon reflects the latest package status immediately after a manual update on your host, you can manually trigger the agent to send results:

bash
/usr/local/bin/patchmon-agent.sh update


This command forces the agent to collect and transmit the current package information to your PatchMon server without waiting for the next scheduled update.
