Extending Kubernetes - Lessons Learned From an L4 Ingress Implementation

on YouTube ↗27m

" summary

Implements a SharedLoadBalancer CRD plus controller that creates one cloud L4 load balancer and maps multiple cluster services to different external ports (uses a dummy port 3333 listener to bootstrap). Controller calls cloud SDKs to add forwarding rules, open security groups/firewalls, create nodePort services, and stores IP and port in CR status so callers know where to connect. Demos show TCP and UDP working on GCP, IBM Cloud (IKS) and AWS; capacity is configurable (demo uses capacity 5 and 2) and provider quirks require per-cloud handling. Code is on GitHub.
