  • Kubernetes Goat
    A Kubernetes cluster, intentionally designed to be vulnerable to practice Kubernetes security. The corresponding documentation guides through a couple of vulnerable spots.
  • podtnl
    "A Powerful CLI that makes your pod available to online without exposing a k8 service"
  • CoreDNS 1.7
    The new CoreDNS housekeeping release removes Kubernetes related plugins and improves metric naming. It is worth mentioning that this is, therefore, a backwards incompatible release.
  • Kube2Hadoop
    "Offline training jobs on Kubernetes, such as TensorFlow or Spark jobs need secure access to datalake like HDFS. However, there exists a gap between the security model of Kubernetes and Hadoop. Kube2Hadoop bridges this gap by providing a scalable and secure integration of Kubernetes and HDFS Kerberos."
