This is an excellent step-by-step guide for setting up a complete CI/CD pipeline on AWS using Jenkins, Docker, and EC2. I appreciate the detailed user-data script, it covers all the essentials like Java 17, Maven, Git, and the SSM agent to make management easier. The breakdown of integrating GitHub and Maven with Jenkins really helps beginners understand the flow.
One suggestion: It would be great to see a follow-up on Jenkins pipeline scripting for automating build and deploy stages fully, including Docker image build and push steps. Also, maybe some tips on securing Jenkins on EC2 and handling credentials would round out the tutorial nicely.
Overall, very useful for anyone looking to get hands-on experience with containerized Java app deployment in the cloud!
