Looking for reading recommendations to understand the details of how code gets from a local machine into production.

I'm having a hard time finding detailed information on the processes related to getting code from a local machine into production. I've found a lot of detailed coding info, but that's not what I'm looking for. I've found helpful DevOps info and it's close, but it's usually focused on one step or product and not the complete generic process. Can you recommend a book, video or web page to learn more? I'd like to understand the steps and why they are performed (trigger build, save to repository, etc.).
