The lectures that utilize the existing Jenkins pipeline start from the basics and try to explain many functions in advance. The advantage and disadvantage of this lecture is that it skips over such in-depth parts, but considering that it is a beginner's lecture, I think it is good to learn how to use it first and then understand it more deeply. The advantage is that you can learn how to use it with shortcuts in a short period of time, and it was good to be able to properly practice the strength of the pipeline, which is detailed step-by-step processing. I strongly recommend it to those who need to use Jenkins pipeline for work starting tomorrow or those who want to finish their portfolio with an advanced distribution method while preparing for a job.
