There are implementations like Harbor, which offer native retention policies for tags. However, if you host a registry like CNCF Distribution, you need additional tooling to automatically delete tags.

In the ever-evolving landscape of cloud-native technologies, Kubernetes has emerged as the de facto standard for container orchestration. As Kubernetes adoption grows, so does the need for robust and efficient networking solutions to facilitate communication between pods and services within a cluster. Two prominent contenders in this space are Cilium and Calico, both offering unique approaches to Kubernetes networking and security. This article delves deep into the intricacies of Cilium and Calico, comparing their features, strengths, and weaknesses to help you make an informed decision for your Kubernetes deployments.

In this episode, we’ll integrate OpenTelemetry with our ASP.NET minimal API and trace everything from database calls to cache hits — all visualized in Jaeger. We’ll also learn how to spot inefficiencies, validate cache behavior, and instrument our code for insights.

Project mention: Show HN: Koreo – The platform engineering toolkit for Kubernetes | news.ycombinator.com | 2025-04-10
I thought Crossplane v2 was only a design proposal at the moment: https://github.com/crossplane/crossplane/pull/6255
But I guess there is an actual preview implementation now? https://docs.crossplane.io/v2.0-preview/
The comparison on Kro would definitely be good to include as there are quite a few similarities. I can write up more on how it compares in a bit.

Over time, registries accumulate a lot of garbage in the form of blobs referenced by old images that are not needed anymore. Many registry implementations, such as CNCF Distribution, offer garbage-collection mechanisms to delete unreferenced blobs and free up storage space. However, for that to happen, old images (tags) referencing them have to be deleted first.

Project mention: Chaos Engineering in Kubernetes: 5 Real-World Experiments to Try Today | dev.to | 2025-05-08
Chaos Mesh is a CNCF open-source project that implements chaos engineering concepts specifically for Kubernetes environments. It achieves this by injecting faults and abnormalities into a Kubernetes cluster or a physical node to analyze how workloads and the environment perform under different failure scenarios.

I contributed to Kyverno for a few months while also managing my internship and college classes and finally the time came when projects for LFX term 2 2024 were announced. I saw the list and Kyverno was not there and once again I had to change my project just before a month from LFX. I was going through all the projects that were coming in LFX, I saw KubeEdge there, KubeEdge is a Kubernetes native edge computing framework. I had some idea about what KubeEdge is and I found the projects really interesting so I decided to apply for LFX under KubeEdge. I applied for two projects, one was about writing new documentation and the other one was about test enhancement. While I was more interested in code contributions but I had a background of working as a technical writer for 8 months and I also had good contributions in Kyverno documentation so I decided to focus more on the documentation enhancement project and also give time to learn things for the tests enhancement project.

Project mention: Kubernetes Cost Management with the New OpenCost Plugin for Headlamp | news.ycombinator.com | 2024-08-14
I believe for AWS, they use these ratios: https://github.com/opencost/opencost/blob/c2de805f66d0ba0e53...
So in your example, 6 CPU + 16GiB is roughly 2x more than 2 CPU and 16GiB, so if that node cost say $6/hr, you'd expect it to be allocated $2 to the first and $4 to the second.
They have these weights for various clouds here: https://github.com/opencost/opencost/tree/c2de805f66d0ba0e53...
