Ask HN: How does Kubernetes modify/add API endpoints at Runtime? I tried reading through the Kubernetes source code but can’t find low level documentation. Can anyone point me to the relevant bits? |

In this case, it depends on the ingress controller used. The default nginx ingress case has some docs: https://kubernetes.github.io/ingress-nginx/how-it-works/
Note that nginx-ingress has limitations as a side effect of its Lua balancer vs normal nginx. As an example, it does NOT do TLS-resume on the nginx<->service hop. Normal nginx would, but the lua balancer lacks the necessary code [1]. In some high volume scenarios, this can cause trouble on the backend.
