Hello, Donkatsu King! This is Sini from JSCODE. Thank you so much for calling it a "lecture like a ray of light for beginners." Actually, when writing pipeline scripts (Jenkinsfile), if you simply copy and paste, it becomes very difficult to apply them later on...! That's why I tried my best to explain it kindly line by line, and I'm so glad that sincerity reached you! Even if Docker or cloud concepts are unfamiliar, the "experience" of running it and checking the results is more important than anything else, and you've handled that process wonderfully!! Now, I hope you try porting this pipeline to your precious personal projects and experience the thrill that deployment automation provides. Thank you once again for your thoughtful review, and I will always be rooting for your future! Thank you. haha
