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.
