Now at the Kubernetes Contributor Summit: IPTables, the end of an era with @Itsuugo and Dan Winship. TL;DR - move away from IPTables if you're not already. #KubeCon

There seem to be a plethora of reasons to move away from iptables. Kernel developers are abandoning IPTables for nftables, it wasn't designed for Kubernetes level scale, it's kind of generally clunky in a lot of today's use cases.

Now checking out an unconference session- "Pod Lifecycle: the good, the bad, and the misunderstood" with @bobbypage! Image Pod Lifecycle is complicated and we have the issues to prove it. Many issues are on the kubelet side, but not all of them. With the wide variety of controllers possible, there are a lot of ways for the lifecycle of a pod to go wrong. #kcsna #KubeCon #Kubernetes ImageImage

It's cool to hear the ways folks today can understand Borg, a technology like 15 years old, via papers about it from 6 years ago- by comparing it to their modern experience using its open source descendant, #Kubernetes today. The goals of borg and the ways they were accomplished are similar enough to k8s to be recognizable, but sometimes accomplished a bit differently. Similar naming conventions (borglets vs kubelets), BCL vs YAML, etc.
