Node Exporter Installation Playbook

Overview

This Ansible playbook is designed to automate the installation and configuration of Prometheus Node Exporter on target Linux systems. It downloads the specified version of Node Exporter, sets up a system user with limited privileges, and configures the systemd service to ensure Node Exporter runs as a background service.

Features

• Downloads the specified version of Node Exporter.

• Creates a dedicated system user for running Node Exporter with /bin/false as the default shell for security.

• Configures Node Exporter as a systemd service for easy management.

• Ensures the service starts on boot and is running.

Requirements

• Ansible installed on your local machine or control node.

• Target servers must support SSH connections and have root privileges (or be sudo-enabled).

Variables

• node_exporter_version: Specifies the version of Node Exporter to be installed. This can be passed as an extra variable when running the playbook.
