I got tired of Googling Docker commands, so I built an interactive cheatsheet

Let me paint you a picture. It's late. You're writing a Dockerfile. You're in the zone — the kind of focus where you're actually moving fast and everything is clicking. You type HEALTHCHECK and your fingers pause. Is it --interval or --period? And what's the timeout default again? Is there a --start-period flag or did you make that up? You open a new tab. You type "dockerfile healthcheck options" into Google. The first result is a Stack Overflow answer from 2017. The accepted answer is wrong. The second answer is right but references a flag that was renamed. You scroll past three more answers, open the official Docker docs, find the right section, get your answer, close five tabs, and try to remember where the hell you were. Three minutes gone. Flow state: destroyed. I've been doing this for years. And I finally got annoyed enough to do something about it. What I built Docker Hub is a free, open-source interactive cheatsheet for all 18 Dockerfile instructions. It lives in your browser,
