Project Overview

ansible-lab is a pet project to practice Ansible and Vagrant. It provisions a simple environment with:

• DB VM: PostgreSQL database server
• App VM: Simple application environment with Python script for DB connectivity check and static HTML page

This project demonstrates practical Ansible skills for SRE/DevOps interviews, focusing on infrastructure automation and configuration management.

Note: The project does not use the outdated vagrant-vbguest plugin due to Ruby compatibility issues. Provisioning is handled fully via Vagrant and Ansible.

Features

• Ansible Automation: Multi-server provisioning using roles and playbooks
• Vagrant Infrastructure: VM management with private networking
• CI/CD Integration: GitHub Actions for syntax validation
• Configuration Management: YAML-based infrastructure as code

Usage

1. Clone the repository:

   git clone https://github.com/DanLinX2004X/ansible-lab.git
   cd ansible-lab

2. Start Vagrant VMs:

   vagrant up

3. Check Ansible syntax (CI also covers this):

   ansible-playbook --syntax-check playbook.yml

4. Verify connectivity:

   ansible all -i inventory.yml -m ping

CI / GitHub Actions

Pipeline triggers on push and pull_request events:

• Ansible playbook syntax check
• Vagrantfile Ruby syntax check
• YAML validation (warnings don't fail pipeline)

Skills Demonstrated

• Ansible: Playbooks, roles, inventory management
• Vagrant: Multi-VM environments, networking
• YAML: Configuration as code
• CI/CD: Automated testing with GitHub Actions
• Infrastructure Automation: End-to-end provisioning
