Day 37: VProfile Project on Docker

Today I containerized the VProfile Project, a Java-based multi-tier web application, using Docker. This practical step helped me solidify my understanding of containerized environments, inter-service communication, and microservice deployment workflows.


๐Ÿ“ฆ What is VProfile?

VProfile is a multi-tier application with the following services:

  • Frontend (Java Spring-based WebApp)

  • MySQL (Database)

  • Memcached (Caching)

  • RabbitMQ (Queueing)

  • Tomcat (Servlet container)

  • Nginx (Web proxy/load balancer)


๐Ÿ›  What I Did Today

โœ… Pulled & Built Docker Images:

  • Used official and custom Docker images for each component.

โœ… Created a docker-compose.yml:

  • Defined all services, dependencies, ports, volumes.

  • Ensured proper networking and health checks.

โœ… Persistent Volumes & Environment Variables:

  • Added volume bindings for data persistence.

  • Managed credentials with .env and Docker secrets.

โœ… Tested Application Stack:

  • Accessed the app in browser via localhost:8080

  • Verified communication between containers using docker exec & logs


๐Ÿ“š What I Learned

  • Multi-container orchestration using Docker Compose

  • Application-level dependencies and linking services

  • Internal DNS via Docker networks (service_name works like a hostname)

  • Simplifying DevOps workflows using Docker


๐Ÿ“Œ Next Steps:

Introduction to Bash scripting
