Over 1 year down the path on learning Kubernetes and just know I had the chance to watch this awesome presentation! I Wish I had seem it earlier, makes things so simple without diving into many technical details, the way a demo should be!

i want to understand the complete flow like below Browser --> API Gateway --> Kubernetes Ingress Load Balancer --> Downstream pods When a request comes to API Gateway how do we call Kubernetes Ingress Load Balancer to serve the request?

Since letsencrypt certificates are invalidated in a relatively short time, what would be the "kubernetes-way" to do a renewal of the certificate, and actually start using the new certificate once it's renewed -- all this without restarting the application, just for the sake of a certificate renewal.

Volume data can be updated on-the-fly, just like files on a mounted filesystem. If you change a secret, such as the lets encrypt cert that kelsey used in his demo, then any pods (containers) that have the secret mounted in a directory will have the contained files updated on-the-fly. So it's automatic, information gets refreshed automatically in the pods almost in real-time, when the secret definition changes in the cluster's central data store. What happens in the container when files change however is a problem for the app developer. That person needs to have some detection mechanism, so that the container can "HUP" nginx, to make it reload the new config/cert. This is typically done using inotify in containers. In short, no need to restart containers if mounted data changes. IIRC the longer version of kelsey's demo shows this in action, where I seem to recall requested a test cert from let's encrypt, showed the browser warning, changed his lets-encrypt plugin config (the extension resource config mentioned in the talk) to point to the production API for lets-encrypt. After a few seconds the new cert was fetched, injected into the containers, an inotify watcher reloaded the nginx config and the browser showed a green padlock icon.

Realised I didn't answer point-blank. Above is a general description of how state changes are propagated to pods and you asked about a special case of that. So the answer is that renewal requires some app to update the cluster with the new cert. This is something his little letsencrypt app (extension resource controller) actually does if I recall correctly (or it might have been the kube-lego variant, the defacto lets-encrypt plugin for kubernetes instead of kelsey's own). It watches for certs that are about to expire renews them when appropriate (ahead of expiration time), updates the cluster secret(s) holding the cert(s) and then the new certs propagate out to the pods as described above. All without having to restart the apps.
