Containerization of a 3-tier Web Application

Project Description

This project involves the containerization of a 3-tier web application consisting of a frontend (Angular), backend (Java/Spring), and a MySQL database. The source code for this application is available in the following repositories: frontend and backend.

Completed Tasks

1. MySQL Database Containerization

   • Created a container for the MySQL database using the official MySQL image.
   • Chose the most suitable storage option and ensured persistent storage for the database.

2. Backend Dockerization

   • Created a Dockerfile for the Backend project following best practices.
   • Applied good practices such as using multi-stage builds, minimizing layers, and specifying version pinning for dependencies.

3. Frontend Dockerization

   • Created a Dockerfile for the Frontend project and applied best practices (similar to the Backend Dockerfile).

4. Docker Network

   • Created a Docker network with an appropriate driver and connected the MySQL database container to this network.

5. Image Security and Publishing

   • Scanned Docker images for vulnerabilities and took necessary actions to mitigate them.
   • Published Docker images to Docker Hub for both Backend and Frontend projects.

6. Application Deployment

   • Successfully deployed the application using docker-compose.
   • Created docker-compose.yml file defining services for frontend, backend, and MySQL database.
   • Ensured application functionality by testing in the browser.

7. Kubernetes Deployment

   • Created Kubernetes manifests (YAML files) for deploying the application in a Kubernetes cluster
   • Configured resource quotas, RBAC controls, health checks, and ingress for the application.
   • Tested application functionality in Kubernetes cluster.

8. Private Docker Image Registry

   • Created a local private Docker image registry to store and manage built images.
