Let’s be honest: when you first heard about HEALTHCHECK in Docker, you probably thought, “That’s for databases and backend APIs. My React/Vue/Svelte app just serves static files. It’s either up or it’s not.”
I thought the same thing. Until a silent production outage taught me otherwise.
Here’s why your frontend container deserves a health check just as much as your Postgres or Node.js API — and how to implement it in under 5 minutes.
The Myth: “Static = Unbreakable”
We treat frontend containers like dumb file servers. After all, nginx serving an index.html either runs or crashes, right?
