As I'm diving into the DevOps world, I've been working with tools like Docker, Kubernetes, Ansible, and Terraform. One consistent thing I see is that a lot of configuration files are written in YAML, whether it's Kubernetes manifests, Ansible playbooks, or CI pipelines. Some of these files can get lengthy, so I'm curious about what it's like in real job scenarios. Do DevOps engineers actually memorize the YAML structures, or is it common practice to refer to documentation and modify examples? Also, during interviews, are candidates expected to write YAML from memory, or can they look things up? I'm just trying to get a grasp of what the actual workflow looks like in the field.

In interviews, it's totally okay to refer to documentation! Most places don't expect you to write everything from memory, especially with YAML. It's just good practice to know the basic structures and what options you have available. Just as important as knowing how to write it is understanding the principles behind what you're doing.
I think it's normal to reference examples, especially when you’re learning. YAML itself is pretty straightforward, but each tool has its specific nuances. The more you use it, the more familiarity you'll gain. I keep a collection of templates for common configurations, which helps when I need to whip something up in a pinch.
That's a smart idea! Having a library of examples can save so much time.
From my experience, memorizing every detail of YAML isn't necessary at all. I typically rely on tools like a linter and autocomplete features in IDEs, which make working with YAML much easier. Over time, you'll naturally remember the structures you use frequently, but there's no harm in checking the documentation whenever you need to. Knowing how to find the right information is what's really valuable.
Totally agree! Autocomplete is a lifesaver, and using a linter really helps catch mistakes.
Honestly, memorization feels more performative than useful. It’s more about knowing what you need and where to find it. I mean, some tools even provide built-in templates, so you don't have to code everything from scratch. Plus, most interviewers these days understand that real-world development involves referencing documentation, not just rote memorization.
Exactly! It's like we’re expected to not just know everything, but to also know how to learn quickly.
Right? Plus, there's nothing wrong with looking things up. Even seasoned pros do it all the time!
