TechnoSophos: Writing a Kubernetes CRD Controller in Rust
In this post, we'll define a Kubernetes Custom Resource Definition (CRD) and then write a controller (or operator) to manage it -- all in 60 lines of Rust code. Over the last several months, I have been writing more and more Kubernetes-specific code in Rust. Even though Kubernetes itself was written in Go, I am finding that I can typically write more concise, readable, and stable Kubernetes code i

What’s new in Kubernetes 1.20?
Kubernetes 1.20 is about to be released, and it comes packed with novelties! Where do we begin? As we highlighted in the last release, enhancements now have to move forward to stability or being deprecated. As a result, alpha features that have been around since the early times of Kubernetes, like CronJobs and Kubelet CRI support, are now getting the attention they deserve. Another noteworthy fact
Guide to OOMKill Alerting in Kubernetes Clusters
Dragan Milic Monday 23 Nov 2020 Intro RAM is most likely the scarcest resource that is first exhausted on your servers. If you’re serious about running software under Linux/Unix, you’re certainly aware of what an OOMKill is. Short refresher: when a program requests a new memory page from the kernel two things can happen. There is a free memory page: The kernel page assigns the page to the process
Kubectl: Developer tips for the Kubernetes command line | Red Hat Developer
Kubectl, the Kubernetes command-line interface (CLI), has more capabilities than many developers realize. For example, did you know that kubectl can reach the Kubernetes API while running inside a cluster? You can also use kubectl to assume different user identities, to select a custom editor to run with the kubectl edit command, and more. In this article, I introduce several kubectl CLI features
Kubernetes: Efficient Multi-Zone Networking with Topology Aware Routing

It signals that when kube-proxy is routing traffic for that service, it should only route
