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. Watch (or listen to) it here: https://kube.fm/troubleshooting-kernel-alex

Pod Topology Spread Constraints is a convenient feature to control how pods are spread across your cluster among failure domains such as regions, zones, nodes, etc. You can also choose the pod distribution (skew), what happens when the constraint is unfulfillable (schedule anyway vs don't) and the interaction with pod affinity and taints. It's a great and straightforward feature, so what could possibly go wrong? In this episode of KubeFM, you will follow Martin and his team's journey in discovering and fixing a production incident (on a Friday afternoon) due to a misconfiguration. You will also learn: - What are Pod Topology Spread Constraints, and how to use them? - How unfulfillable scheduling requirements could lead to un-schedulable pods. - How to detect and alert on unscheduled pods. - How to manage your team during an incident to keep them calm and focused.
