This was the lecture I was looking for. Other lectures are Docker A-Z, CI/CD tools A-Z, AWS A-Z, but I wanted to learn the parts necessary for practical work rather than learning one in depth and see how the CI/CD environment is run as a whole first. This lecture satisfied what I needed. He explained it clearly and I don't know how he knew it, but he explained only the necessary parts. This is the first time I completed an Inflearn lecture :) I recommend it to those who are new to CI/CD :)
