Many Kubernetes users liked Lens (or even still do). After it became not Open Source and Lens ID was introduced, many switched to OpenLens. Unfortunately, that fork did not last long and hasn’t issued any releases since July 2023. However, it turned out to be another fork, which is currently active: Freelens.

This project started around January of this year, and released its v1.0.0 in February and further v1.1.0 just five days ago. Today, Freelens:

- is fully compatible with the latest Kubernetes version (1.32);
- comes with kubectl v1.32.3 and Helm v3.17.2;
- is based on Electron 34.3.3 with Node 20.18.3 and Chrome 132.0.6834.210;
- requires GNU C Library 2.34+ for Linux (i.e. Debian 12, Ubuntu 22.04, Fedora 35, openSUSE Leap 15.4), macOS 11+ or Windows 10+ to run.

Don’t miss the news regarding five recent critical vulnerabilities in ingress-nginx, including CVE-2025-1974 scored at 9.8 CVSS!

The Kubernetes blog post states that over 40% of Kubernetes administrators rely on ingress-nginx and should take action immediately. Otherwise, a malicious user with no credentials can take over your Kubernetes cluster by exploiting configuration injection vulnerabilities via the Validating Admission Controller.

The latest ingress-nginx releases, v1.12.1 and v1.11.5, are already available with all five vulnerabilities fixed.

During today’s KubeCon keynotes, it was announced that Headlamp became a part of Kubernetes SIG UI. You can already see that its official repository is now kubernetes-sigs/headlamp.

SIG UI is a Kubernetes Special Interest Group that “covers all things UI related” to K8s. Originally, its efforts were focused on the Kubernetes dashboard, and now they would be extended to Headlamp. Headlamp was originally created in Kinvolk (acquired by Microsoft in 2021) and became a CNCF Sandbox project in 2023.

Release Spotlight: Kubeflow 1.10

Kubeflow, a machine learning toolkit for Kubernetes (a CNCF Incubating project), has received many significant changes with its 1.10 release. Training Operator now supports JAX for distributed training, and Katib introduced a new high-level API for hyperparameter tuning. Spark Operator became a core Kubeflow component, with its 2.1.0 included in the platform.

The project got a new user-friendly web UI for Model Registry to manage ML models. The Model Registry was also better integrated with KServe via Custom Storage Initializer (CSI), and KServe got a new Python SDK. Finally, lots of security-related updates arrived, such as leveraging rootless containers in Kubeflow manifests and replacing OIDC-authservice with oauth2-proxy.

Other noticeable updates in the Cloud Native space:

1. KubeVirt, a virtual machine management solution for Kubernetes (a CNCF Incubating project), released its v1.5 a month ago. It brought several features to GA, including migration update strategy and volume migration, auto resource limits for VMIs, VM live updates for hotplugging of CPU/memory/volume resources, and a network binding plugin. It also introduced migrations for hotplugged volumes and dynamic control for the network interface’s link state.

2. Headlamp, a Kubernetes web UI (now part of Kubernetes SIG UI), released 0.30.0. It features two new locales (Traditional Chinese and Italian), an ability to show Custom Resources details in the overlay panel, and a few other improvements.

3. Fluent Bit, a lightweight telemetry agent developed under the umbrella of Fluentd (a CNCF Graduated project), has reached v4.0.0. It comes with conditional processing for logs (i.e. modifying logs based on specific field values), a new trace sampling processor with a pluggable architecture, security enhancements, and experimental support for plugins written in Zig.

4. Thanos, highly available Prometheus with long-term storage (a CNCF Incubating project), released v0.38.0, which added OTLP receiver, native histogram downsampling, caching for regex matchers in series calls, support for chain deduplication algorithm and query offset, and more.

5. Flagger, a progressive delivery Kubernetes operator (part of Flux, a CNCF Graduated project), released 1.41.0, introducing Knative support, support for primary backend cookies in session affinity (Gateway API), and added headers to the Prometheus requests.

6. kgateway, a Cloud Native API Gateway and AI Gateway (a recently accepted CNCF Sandbox project), unveiled the second major release, v2.0.0. It came with custom resources extending Gateway API, better traffic management and security capabilities, open-sourced AI Gateway, and Istio Ambient Waypoint integration.

7. KEDA, a Kubernetes-based Event Driven Autoscaling (a CNCF Graduated project), was updated to v2.17.0, featuring two new scalers (NSQ and Temporal) and a few deprecations.

Many of us thought or even seriously considered using a general-purpose language instead of YAML for the Kubernetes manifests. Here’s a new project that is solving this issue.

k8skonf allows you to describe your Kubernetes resources in TypeScript and convert them to regular YAML manifests. It’s similar to the cdk8s framework but intentionally limited by one specific language, ensuring its full support. Currently, it also works with CRDs and Helm charts. The project roadmap mentions plans to support Kustomize files and multiple versions of K8s.

OpenTofu just became a CNCF Sandbox project.

#news #cncfprojects

The latest Open Source drama came straight into the CNCF's hands. We haven’t seen such cases before: Synadia, the principal maintainer and original creator of NATS, a CNCF Incubating project, wants to get the ownership for this project back from the vendor-neutral home.

Synadia’s plan involved becoming the owner of the NATS project again and switching to the BSL license—which OSI does not consider Open Source—for future releases to ensure its business sustainability. However, CNCF insists there is no “way out” for the foundation's projects and suggests forking its repositories instead.

While Synadia is undoubtedly the leading developing force for NATS, the CNCF has helped the project thrive in many ways since its donation in 2018. In addition to the obvious marketing benefits, NATS also received funding for two third-party security audits and financial support for trademark legal expenses.

If Synadia stops contributing to NATS and there is not enough interest from other community members in developing a project, it might end up archived in the CNCF. The CNCF TOC has already started evaluating the health of this project.

Find more details about this story in the:
- original blog post by CNCF (posted on April 24th and updated on April 28th);
- official answer from Synadia (April 25th);
- Bluesky thread started by Joe Beda (posted on April 26th and answered by Derek Collison, founder and CEO @ Synadia);
- CNCF TOC issue regarding NATS health state.

#news #cncfprojects

What could be the best possible outcome of the NATS case? “CNCF and Synadia today announced that the widely-adopted NATS project will continue to thrive in the cloud native open source ecosystem of the CNCF with Synadia’s continued support and involvement.”

It’s not a fiction, it’s for real! Bravo to all the parties involved 🥳
