DevOps Challenge Day 3⚙️: Continuous Integration (CI)

Imagine you’ve got a pot of spagetti (code) in your hands and you throw it against the wall (the server), hoping it’ll stick. But instead, it slides down and creates a gooey mess - that’s your code deployment without continuous integration (CI). CI serves as an integration guardian to you. It is like that meticulous friend who insists on fixing everyone’s collars at parties. Nobody likes a skewed bowtie or broken code on production. CI also serves as an early warning system. Do you remember that smoke alarm that went off because you tried to make toast? That’s CI for your code. It catches the issues before they become blazing production infernos!

There are several good practice one can follow:

1. Don’t hoard your code like it’s the last roll of toilet paper during the quarantine. Small and frequent commits help spot the errors when they’re just baby issues and not full-blown crises. Try to commit little and commit often.
2. I hate vacuuming which is why I got a Roomble. The same principle applies to CI’s as well. If you got a repepetive task, why not automate it allowing you to focus on the fun stuff.
3. If your grandma knits you sweater, you wouldn’t go pulling threads, right. Once your code is built, don’t change it. It is like an immutable build.
4. IaC also plays a huge role nowadays, think of it as LEGO instruction for your infrastructure. You wouldn’t wing building a LEGO castle, would you? Similarly your infrastructure should be cofified and versioned.
5. Imagine IKEA furniture without the manual. That would be a pure chaos. Every CI process, tool, and pipeline needs clear documentation which is why the documentation is crucial.
