Overview
A request used to confirm an app is ready for traffic.
Definition
A request used to confirm an app is ready for traffic.
Real-world example
Better-PaaS polls GET /health every few seconds; when it returns 200, traffic routes to the new container during a deploy.
Common mistake
Health endpoint requires authentication or returns 404, so deploys never complete and traffic never switches.
Better-PaaS in practice
Configure health check path and port per app. A failing health check blocks zero-downtime routing.
FAQ
Is health check only relevant to Better-PaaS?
No. health check appears across Docker, cloud platforms, and self-hosted tooling. Better-PaaS exposes the concept in deploy logs, dashboard fields, or docs when it affects your app.
