- Ensuring YAML best practices using KubeLinter
YAML is a kind of holy grail in the Kubernetes world; at least without we would need to deal with JSON... However, they are easy to misconfigure and abuse. StackRox introduced a new open-source tool named KubeLinter aimed at identifying any misconfigurations in YAML files. It also works with Helm charts and does a static code analysis to adjust to make it suitable to your own conventions.

- KEDA 2.0 - Taking app autoscaling to the next level
Kubernetes Event-Driven Autoscaling (KEDA) progresses in its evolution after getting accepted as a Sandbox project earlier this year at the CNCF. With KEDA 2.0, the community split the scalable resources in ScaledObject and ScaledJob. What catches us more are the multiple triggers for a single source. This means different event streams can scale your application up.

- Cilium 1.9: Maglev, OpenShift, HA Cilium Operator
What is Maglev? A hashing algorithm for the back-end selection of Cilium's eBPF-based north-south load balancer significantly reduces CPU overhead to handle millions of packages effectively. We also have to mention the OpenShift support and the high availability update of the Cilium operator.
- A Guide to Linux Operating Systems for Kubernetes
Yet, most OS carry a massive overload of packages with them. In production environments, this leads to an additional operational effort to ensure proper hardening and minimize the risk of interference. Managed service providers saw the need to optimize their images for the containerized workload. This trend moved on to different vendors for edge deployment, hypervisor, or general solution like Talos OS.
