Day 3 | How to Dockerize a Spring Boot Application | Docker Zero to Hero Series | Docker Tutorial
🐳 Welcome to Day 3 of the Docker Zero to Hero series!
Link for Spring boot bash script:
https://docs.google.com/document/d/1W...
In this video I'll show you how to deploy a Spring Boot
application — first the manual way and then the Docker way —
so you can clearly see why Docker makes deployment
so much simpler and more reliable!
I'll walk you through writing a Dockerfile for Spring Boot,
building the image, running the container with port mapping
and verifying everything works using a curl request!

🎯 WHY DOCKERIZING APPLICATIONS IS A CORE DEVOPS SKILL
Every DevOps engineer is expected to know how to
take an application and containerize it.
Spring Boot is one of the most widely used frameworks
in Indian product and service companies —
and knowing how to Dockerize it is a skill that
directly helps you in interviews and real projects.
This video shows you the exact workflow used in
real production environments — from code to running container.

📌 WHAT YOU WILL LEARN IN THIS VIDEO
✅ How to deploy Spring Boot application manually
✅ Problems with manual deployment approach
✅ How to write a Dockerfile for Spring Boot application
✅ How to build a Docker image from the Dockerfile
✅ How to run the Docker container with port mapping
✅ What is port mapping and why it is needed
✅ How to verify your application using curl request
✅ Manual deployment vs Docker deployment comparison

🔍 WHO IS THIS VIDEO FOR
This video is perfect for you if you are:
👉 A Java developer who wants to containerize applications
👉 A DevOps engineer learning to Dockerize real applications
👉 Someone preparing for Docker or Kubernetes interviews
👉 Anyone who wants to see manual vs Docker deployment side by side
👉 A backend engineer moving into DevOps roles

💡 MANUAL VS DOCKER DEPLOYMENT — KEY DIFFERENCE
Manual Deployment Problems:
→ Need to install Java on every machine separately
→ Works on dev machine but breaks on server
→ Environment differences cause unexpected failures
→ Hard to replicate across multiple servers
→ No isolation between applications
Docker Deployment Benefits:
→ Everything packaged inside the container
→ Runs identically on every machine
→ No dependency conflicts ever
→ Easy to scale and replicate
→ Complete isolation between applications
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
⚙️ WHAT IS COVERED IN THE LIVE DEMO
→ Running Spring Boot application manually
→ Writing Dockerfile for Spring Boot with correct base image
→ Building Docker image using docker build command
→ Running container with -p flag for port mapping
→ Explaining what port mapping does and why it matters
→ Sending curl request to verify application is responding
→ Comparing both approaches side by side
