This guide covers how to set up and configure ansible on a Linux VPS. Whether you're running a production environment or a development setup, these instructions will help you get started quickly and securely.

Prerequisites

Version control (Git) installed
Basic familiarity with the Linux command line
The relevant IaC tool installed on your workstation
A VPS running Ubuntu 22.04 or later (2GB+ RAM recommended)

Project Structure

The vault component plays a crucial role in the overall architecture. Understanding how it interacts with ansible will help you make better configuration decisions.


# main.tf - Terraform configuration
terraform {
  required_providers {
    null = {
      source = "hashicorp/null"
    }
  }
}

resource "null_resource" "ansible" {
  provisioner "remote-exec" {
    inline = [
      "apt-get update",
      "apt-get install -y vault",
    ]
  }
}

The configuration above sets the recommended values for a VPS with 2-4GB of RAM. Adjust the memory-related settings proportionally if your server has different specifications.

Resource Definitions

Regular maintenance is essential for keeping your ansible installation running smoothly. Schedule periodic reviews of log files, disk usage, and security updates to prevent issues before they occur.
