Percona Everest becomes OpenEverest

Percona Everest is a Cloud Native database platform that helps operating PostgreSQL, MongoDB, and MySQL databases in Kubernetes environments. Originating as a vendor-owned solution, it has now evolved into an independent Open Source project called OpenEverest. Percona has also formed a subsidiary, Solanica, that is fully focused on developing OpenEverest. The authors plan to donate OpenEverest to CNCF soon.

Kubernetes Dashboard is getting archived

Yesterday, the Kubernetes Dashboard maintainers announced that the “project will be archived and sunset in the coming days/weeks.” It has been developed in the Kubernetes SIG UI but lacked active contributors and maintainers for a while.

The authors recommend Headlamp as an alternative to Kubernetes Dashboard, since it became a Kubernetes SIG UI project last year.

Here come some of the interesting Kubernetes-related articles recently spotted online:

1. "How Airbnb Runs Distributed Databases on Kubernetes at Scale" by ByteByteGo.

Instead of limiting a database cluster to one Kubernetes environment, they chose to deploy distributed database clusters across multiple Kubernetes clusters, each one mapped to a different AWS Availability Zone. This is not a common design pattern. Most companies avoid it because of the added complexity. But Airbnb’s engineers saw it as the best way to ensure reliability, reduce the impact of failures, and keep operations smooth.

2. "Kubernetes Configuration Good Practices" by Kirti Goyal, Kubernetes blog.

This blog brings together tried-and-tested configuration best practices. The small habits that make your Kubernetes setup clean, consistent and easier to manage. Whether you are just starting out or already deploying apps daily, these are the little things that keep your cluster stable and your future self sane.

3. "How Google Does It: Building the largest known Kubernetes cluster, with 130,000 nodes" by Besher Massri and Maciek Różacki, Google.

At Google Cloud, we’re constantly pushing the scalability of Google Kubernetes Engine (GKE) so that it can keep up with increasingly demanding workloads — especially AI. GKE already supports massive 65,000-node clusters, and at KubeCon, we shared that we successfully ran a 130,000-node cluster in experimental mode — twice the number of nodes compared to the officially supported and tested limit. [..] In this blog, we take a look at the trends driving demand for these kinds of mega-clusters, and do a deep dive on the architectural innovations we implemented to make this extreme scalability a reality.

4. "93% Faster Next.js in (your) Kubernetes" by Matteo Collina, Platformatic.

We'll start by examining the complications of running this powerful framework in your own environment, and get under the hood (and I mean, down to the kernel) about why they happen. Then, we'll walk you through the approach we took with Watt to solve them, and what it means for you if you happen to run Next.js on any other Node.js CPU-bound workload on-prem.

5. "OpenPERouter -- Bringing EVPN to Kubernetes" by Mengxin Liu.

Recently, while researching EVPN as a multi-tenancy solution for physical networks, I discovered the open-source project OpenPERouter. It introduces the concept of EVPN into container networking, providing a new approach to achieving multi-tenancy in Kubernetes. This solution not only unifies software and hardware network architectures but also offers some compatibility with existing CNIs like Calico, which advertise routes via BGP.

6. "Kubernetes 1.35: Deep dive into new alpha features" by Kirill Kononovich, Palark.

The Kubernetes 1.35 release, scheduled for December 17th, has gift-wrapped a variety of experimental improvements designed to enhance infrastructure flexibility and security. In this overview, we focus on its Alpha features extending across a broad spectrum of tasks: from watch-based route controller reconciliation and the long-awaited Gang Scheduling for AI/ML workloads to the secrets field for passing Service Account tokens, mutable volume attach limits, and proxying API server requests to fix version skew.

7. "Kubernetes 1.35 - New security features" by Víctor Jiménez Cerrada, Sysdig.

Kubernetes 1.35 will be released soon, bringing 17 changes to its security features. It includes new validations, the deprecation of old technologies, and broader support for user namespaces, to name a few.

It's time to share our latest digest of the prominent software updates in the Cloud Native ecosystem!

1. Gateway API, a part of the Kubernetes SIG Network, reached its 1.4. It declared a few features, including supportedFeatures in the GatewayClass status and named rules for Routes, GA. It also introduced three experimental features, such as a mesh resource for service mesh configuration, default gateways, and externalAuth filter for HTTPRoute.

2. Istio (a CNCF Graduated project) 1.28 introduced the InferencePool v1 API to improve managing and routing AI inference workloads, native nftables support in the ambient mode, better ambient multicluster deployments, enhanced security features, and more.

3. Kustomize, which is also developed in a Kubernetes SIG, released v5.8.0. This version enabled replacements and patch values in the structured data and regex support for replacement selectors.

4. Spin, a framework for building and running cloud microservices with WebAssembly (a CNCF Sandbox project), was updated to v3.5 with WASI Preview 3 support. Other changes include a new Spin Rust SDK, configurable static HTTP responses, and OpenAI integration support.

5. Kueue, a set of APIs and a controller for job queueing in Kubernetes, got lots of new features in v0.15.0. They include a new experimental kueue-populator to create default resources, admission checks to control the delay by external and internal controllers, an optional interface for custom Jobs to activate and deactivate them, TAS support for the Kubeflow Trainer integration, numerous improvements in MultiKueue, and many more.

6. KubeVirt, a virtual machine management add-on for Kubernetes (a CNCF Incubating project), released v1.7.0. It introduced decentralised live migration, support for DRA devices in VMI, generalised migration priority, support for auto-healing strategy in VMPool, and experimental support for AMD SEV-SNP and Intel TDX.

7. Freelens, a GUI for managing Kubernetes clusters, was updated to v1.7.0, featuring an improved YAML editor, Pod-level resource aggregation, Windows Portable distribution, and better extension API.

This project has been around for a while, but it is especially useful now, given the upcoming retirement of the Ingress NGINX controller.

Ingress2gateway is part of the Gateway API SIG-Network subproject, focusing on translating Ingress and provider-specific CRDs to Gateway API resources. It supports Ingress NGINX and several other providers (including Apache APISIX, Cilium, Istio, GCE, Kong, NGINX Ingress, and OpenAPI).

However, it’s essential to note that it doesn’t support all the annotations available. The list of those supported for Ingress NGINX is available here.

External Secrets Inc. ceased to exist

The commercial company behind External Secrets Operator (a CNCF Sandbox project) announced its shutdown. On the bright side, it has released all its proprietary software as Open Source; it is now available on GitHub.

As you might recall, earlier this year recently, the ESO project itself paused releases due to a critical need for maintainers. Luckily, new people were found, and releases were revived, including the prominent v1.0.0, which was just two weeks ago.

#news

The announcement of the Ingress NGINX controller retirement led to wide, ongoing discussions in the Cloud Native community. Here are quotes and links to the thoughts of some well-known folks:

Tom Hockin, Kubernetes co-founder (source):

“The people who currently work on ingress-nginx do so FOR FREE. They have been doing it largely because they feel a sense of duty. They do not need to be berated. In the 2 years this has been a topic, almost nobody has stepped up to help, and there are no new maintainers in the pipeline. Shuttering this project is necessary, and IMO, a better result than pretending it is healthy when it is not.”

Benjamin Elder, Kubernetes Steering Committee (source):

“People need to understand, lots of contributors are willing to do maintenance work, but it simply isn't free, and only doing maintenance generally isn't sustainable. We all have bills to pay and careers to pursue and it's very difficult to succeed doing nothing but maintenance because everyone wants that work for free.”

William Morgan, CEO @ Buoyant (source):

“The actual problem in the CNCF community is instead one of expectations: that all these open source projects I use (on my company’s dime) to build my systems (that allow my company to make money) should be free. And always up to date. And should fix my bugs. And add new features. And somehow this should all just happen magically.”

Kat Cosgrove, Kubernetes Steering Committee (source):

“The ingress-nginx deprecation is the inevitable result of the fundamentally broken way for-profit companies consume open source software, not a reflection on the state of the CNCF or Kubernetes. It had to happen.”

Ingress NGINX will be retired soon

Another significant announcement made during KubeCon NA involved deprecation. Kubernetes SIG Network and the Security Response Committee declared that Ingress NGINX will be retired in March 2026.

This Ingress controller was developed a long time ago as an example implementation of the API. However, its broad adoption and excess flexibility (e.g., "snippets" annotations) became “today’s insurmountable technical debt.” A recent attempt to replace it with InGate (we covered it in this post) failed, and the project became unsustainable, leading to a difficult decision to retire it.

Users are advised to migrate to Gateway API or another Ingress controller as fast as they can.

P.S. Don’t confuse Ingress NGINX with NGINX Ingress. There is a long-lasting naming confusion for these projects.
