It’s that most wonderful time of year! Even though it’s been extra challenging for everyone, we can still take a breath, reflect on lessons learned, and look to fill our proverbial cups with knowledge to take into the New Year. We thought we’d revisit a few of our most popular Automation and AIOps resources from 2020.
One of the most typical challenges when deploying a complex application is the handling of different deployment environments during the software lifecycle. The most typical setup is the trilogy of QA/Staging/Production environments. An application developer needs an easy way to deploy to the different environments and also to understand what version is deployed where. Specifically for Kubernetes deployments, the Helm package manager is a great solution for handling environment configuration.

A few weeks ago a solution engineer discovered a critical flaw in Kubernetes architecture and design, and announced that a “security issue was discovered with Kubernetes affecting multi-tenant clusters. If a potential attacker can already create or edit services and pods, then they may be able to intercept traffic from other pods (or nodes) in the cluster.” If a hostile user can create a ClusterIP service and set the spec.externalIP field, they can intercept traffic to that IP.
