A cloud native Kubernetes Global Balancer @ FOSDEM 22

k8gb is DNS based global service load balancer that can interconnect multiple Kubernetes clusters into one resilient system. Join this talk to learn how it can handle a failover scenario when pods in one cluster go down and second cluster in different location saves the situation. k8gb is an open-source Kubernetes operator that is deployed in each participating cluster. It is comprised of CoreDNS, ExternalDNS and the k8gb controller itself. Using ExternalDNS it can create a zone delegation on a common cloud DNS server like Route53 or Infoblox so that the embedded CoreDNS servers work as an authoritative DNS. K8gb controller makes sure these CoreDNS servers are updated accordingly based on the readiness probes of the application. In this sense this solution is unique, because it is using Kubernetes native tools with customisable probes and battle tested DNS protocol instead of HTTP pings or other similar approaches where single point of failure might be a problem. In k8gb architecture all k8s clusters are equal and there is no SPoF except the common edge DNS server.

log2rbac @ DevConf mini 22

If you have ever developed an operator pattern for Kubernetes, you have probably had to tweak your service account and assign it to a role. Setting up the RBAC correctly is not that hard, but it's not fun and it distracts you from the real problem the operator is about to solve. This often leads to assigning the cluster admin to the operator and neglecting the security altogether. Log2rbac is a tool (yet another operator) that aims to solve this issue. It assists you with setting up your RBAC roles that are tailored for your application's needs. Come to see this talk and learn more.
