Orchestration Tools for Containers - Final Assignment

This repository contains the solutions for the ONPK-Final Assignment of the course "Orchestration Tools for Containers". The work demonstrates the deployment of a microservices-based application with a frontend, backend, and MongoDB, leveraging modern DevOps practices.

Structure

The repository is organized into the following directories:

1. Docker

• Contains Docker configurations and Dockerfiles for both the backend and frontend applications.
• Subdirectories:
  • BackEnd: Dockerfile and related resources for the backend service.
  • FrontEnd: Dockerfile and related resources for the frontend service.

2. Helm

• Contains Helm charts for deploying the frontend and backend services, along with MongoDB.
• Supports environment customization via values-onpkapp.yaml.

3. CI/CD

• Tekton pipelines for automating the build and deployment processes.
• Includes secrets and RBAC configurations necessary for pipelines.
• Demonstrates CI/CD best practices using Tekton and FluxCD.

4. Terraform

• Infrastructure as Code (IaC) using Terraform to provision resources in Microsoft Azure.
• Modules include Azure Kubernetes Service (AKS), Azure Container Registry (ACR), and Virtual Network.

Objectives

The main objectives of the assignment are:

1. Dockerization: Containerizing frontend and backend applications.
2. Helm Deployment: Using Helm charts to automate Kubernetes deployments.
3. CI/CD Pipelines: Automating build and deployment using Tekton pipelines.
4. Cloud Infrastructure: Provisioning Azure infrastructure using Terraform.

Key Features

• Docker: Efficient containerization of applications.
• Helm Charts: Modular, reusable configurations for Kubernetes deployments.
• Tekton Pipelines: CI/CD pipelines that automate Docker builds and Kubernetes deployments.
• Terraform: Scalable and reproducible cloud infrastructure.
• DevOps Principles: Emphasis on automation, high availability, and security.

Getting Started

Prerequisites

• Docker
• Kubernetes (Minikube or Azure AKS)
• Helm 3+
• Tekton Pipelines
• Terraform

Steps

1. Docker: Navigate to the Docker directory, build the images for both backend and frontend, and push them to Docker Hub.
2. Helm: Use the Helm charts in the Helm directory to deploy the services.
3. CI/CD: Set up the Tekton pipelines for building and deploying your images.
4. Terraform: Deploy Azure infrastructure by running the Terraform scripts in the Terraform directory.

Notes

• Make sure to configure values.yaml files for Helm deployments.
• Update credentials in the secrets files for Tekton pipelines.
• Verify the MongoDB initialization scripts before deployment.
• Document your changes and configurations in the relevant directories.
