Kubernetes ยท End-to-end flow

From ConfigMap to a working HTTPS response

Read the settings path first, then follow the browser request. Swipe sideways on a small screen.

ConfigMap delivery and HTTPS request flow An operator saves a ConfigMap, Kubernetes projects its file into a Pod, and NGINX loads it alongside TLS files from a Secret; browser traffic passes through an externally reachable Service to NGINX and a response returns. INSIDE THE NGINX POD 1 / DELIVER THE SETTINGS Saving a setting does not make NGINX use it. The file must arrive, then NGINX must read it. APPLY PROJECT START OR RELOADCheck with nginx -t first.
