Too Long; Didn't Read
Kubernetes is an open source container orchestration tool that can automatically scale, distribute, and handle faults on containers. The ephemeral nature of containers which spin up and down frequently makes them even harder to monitor and trace. The shared OS kernel that makes containers lightweight also makes it tough to create good container isolation or prevent abuse of host resources. These are fairly young platforms (compared to Linux or VMware) so CVE (Common Vulnerabilities and Exposures) can be found even in the most common utilities.
