DevOps Testing Repository

This repository is a playground for exploring and testing various DevOps tools commonly used in infrastructure automation, configuration management, and CI/CD pipelines. It is designed to be a learning resource and a place to document workflows, scripts, and example configurations.

Table of Contents

Overview

This repository contains code samples, scripts, and configuration files to help with the following:

  • Automating infrastructure provisioning using Terraform
  • Managing configuration for servers and applications with Ansible
  • Implementing DevOps best practices and experimenting with CI/CD workflows
  • Testing integrations between Terraform, Ansible, and cloud providers (e.g., AWS, Azure)

The goal is to provide a hands-on environment for learning and experimenting with these tools.

Technologies Used

  • Terraform: For infrastructure provisioning and management.
  • Ansible: For configuration management and application deployment.
  • Python: For scripting and automating custom tasks.
  • Bash/PowerShell: For shell scripting as needed.
  • CI/CD Tools: GitHub Actions, Jenkins (if applicable).

Getting Started

Prerequisites

To use this repository, you’ll need:

  • Terraform installed
  • Ansible installed
  • Access to a cloud provider (e.g., AWS, Azure) with credentials set up
  • Git, Bash, and optionally Python 3.x for additional scripting

Installation

  1. Clone the repository:

    git clone git@github.com:ejohnguia/devops-train.git
cd devops-train

  2. Set up environment variables for Terraform and Ansible if needed:

    export ACCESS_KEY_ID=your_access_key
export SECRET_ACCESS_KEY=your_secret_key

  3. Install Python dependencies (if any):

    pip install -r requirements.txt

Tools to Be Explored

Based on the DevOps Roadmap, the following tools and concepts will be explored as part of this repository:

  • Operating Systems: Focusing on Linux fundamentals and shell scripting
  • Programming/Scripting: Python and Bash for automation
  • Infrastructure as Code (IaC):
    • Terraform: Automating infrastructure setup on cloud providers
    • CloudFormation (AWS), ARM Templates (Azure): To be explored for cloud-native IaC
  • Configuration Management:
    • Ansible: Automating application and environment configurations
    • Chef and Puppet: To be considered for advanced use cases
  • CI/CD Tools:
    • GitHub Actions: For CI/CD pipelines
    • Jenkins: To be explored for end-to-end automation
  • Containers & Orchestration:
    • Docker: Building and running containerized applications
    • Kubernetes: Managing container clusters
  • Monitoring & Logging:
    • Prometheus & Grafana: Setting up metrics and visualization
    • ELK Stack (Elasticsearch, Logstash, and Kibana): Centralized logging
  • Cloud Providers:
    • AWS, Azure, Google Cloud: Testing IaC and configuration management across providers
  • Networking Basics: Understanding key concepts for network configuration and security
  • Version Control:
    • Git: Branching strategies, workflows, and best practices

This list will expand as the project grows, incorporating additional tools and techniques aligned with DevOps best practices.
