How hard could it be to debug a network issue where pod connections time out?

It could take weeks if you are (un)fortunate like Alex.

But Alex and his team didn't despair and found strength in adversity while learning several Kubernetes networking and kubespray lessons.

In this KubeFM episode, you'll follow their journey and learn:

- How a simple connection refused led to debugging the kernel syscalls.
- How MetalLB works and uses Dynamic Admission webhooks.
- How Calico works and assigns a range of IP addresses to pods (and what you should watch out for).
- How to use tcpdump and strace to debug network traffic.
