Introducing kube-iptables-tailer: Better Networking Visibility in Kubernetes Clusters
Saifuding Diliyaer, Box

We needed a mechanism to seamlessly deliver alerts about those iptables packet drops based on their network policies to help app owners quickly diagnose the corresponding issues. To solve this, we developed a service called kube-iptables-tailer to detect packet drops from iptables logs and report them as Kubernetes events. We are proud to open-source kube-iptables-tailer for you to utilize in your own cluster, regardless of whether you use Calico or other network policy tools.

How do you connect Kubernetes clusters located in different data centres?
Daniele Polencic, learnk8s

It’s relatively common to see infrastructure being replicated and distributed in different geographical regions, particularly in regulated environments. If one of the regions becomes unavailable, you can always route your traffic to another location and continue serving traffic. When it comes to Kubernetes, you might want to use a similar strategy and distribute your workloads in different regions. You may have one or several clusters per team, region, environment, or a combination of them. Your clusters may be hosted in different cloud providers and on-premise. But how should you design the infrastructure for such geographical split?
