While we’ve seen many GUIs for Kubernetes lately, new projects still keep appearing. Here’s a small Web client that went public this August.

teleskopio is a new Web UI for K8s that emerged as a result of personal research. It allows you to access your clusters as admin or viewer and comes with numerous features:
- Managing cluster workloads (Deployments, StatefulSets, Jobs, etc.), networking, storage, and access control;
- Embedded Monaco editor with syntax highlighting for creating/editing resources;
- A cluster overview for seeing its overall health and activity;
- Displaying live resource changes, Pod logs and event history;
- Customisable UI: configurable fonts, light and dark themes.

CNCF projects get access to Docker Sponsored Open Source program

CNCF has just announced a new partnership with Docker, Inc., which provides CNCF projects with direct access to the Docker Sponsored Open Source (DSOS) program. This means they can benefit from unlimited image pulls from Docker Hub, access to Docker Scout for vulnerability analysis and policy enforcement, automated image builds from source, and Docker usage metrics and engagement insights.

Have you heard of schedulingGates for Pods in Kubernetes (this feature went stable in v1.30)? They let you control when a Pod is ready to be considered for scheduling. There’s a new project that makes this process declarative.

KSGate is a Kubernetes controller that manages Pod scheduling by using declarative gates and conditions. With it, workloads can get annotations that will match scheduling gates and define the conditions via powerful CEL expressions: they must evaluate to true for the condition to be satisfied. For example, the scheduling condition can be a dependent Pod with a specific name and currently being in a particular phase.

PodCertificateRequests is a new API (introduced in Kubernetes v1.34 as alpha) that enables the provisioning of certificates to workloads running as Pods within a cluster. Here’s a controller to simplify leveraging this new feature.

Pod-certificate-signer is a controller that creates PodCertificateRequest for your Pods with a custom x509 signer. This tool:
- signs TLS/mTLS certificates for Pods (or denies issuing them based on the relevant configuration);
- allows you to use Pod annotations for certificate configurations;
- validates requests by checking whether the CA-provided or mounted files exist and ensuring that the CA is valid;
- logs all decisions and errors.

CloudNativePG switches to its own Docker images

Last month, the PostgreSQL Docker Community discontinued support for Debian bullseye for the official postgres image. Following this news, CloudNativePG (a CNCF Sandbox project) decided to switch to its own images. By establishing its build process that uses Docker Bake, the project now fully controls the entire stack provided with its Kubernetes operator.

The PostgreSQL images produced by CNPG are based on Debian stable and oldstable and rebuilt weekly, cover PgSQL v13-v17, support AMD64 and ARM64, include popular extensions (such as PGAudit, pgvector, PostGIS and pgRouting), and come with SBOMs.

Excited to present our newest digest of the prominent software updates in the Cloud Native ecosystem!

Release Spotlight: Flux v2.7.0

At the end of September, Flux (a CNCF Graduated project) released its v2.7.0, marking the general availability of Flux Image Automation APIs and controllers, i.e. image-reflector-controller and image-automation-controller working together to update Kubernetes manifests in Git when new container images appear in container registries.

Other new features include watching for changes in ConfigMaps and Secrets, integration of Kubernetes Workload Identity at the object level for all Flux APIs, OpenTelemetry tracing for Flux reconciliations, and the artifact generators implemented in a new source-watcher controller.

Other noticeable updates in the Cloud Native space:

1. K3s, a lightweight Kubernetes distribution (a CNCF Sandbox project), was updated to 1.34, which is now based on Kubernetes v1.34 and brings several significant changes. Namely, they are an increased automatic certificate renewal window, optional airgap image tarball imports, enhanced certificate check output, certificate management for kube-scheduler and kube-controller-manager, retention flag for S3-stored snapshots, and an official governance model for the project.

2. Freelens, a fork of Open Lens (the core of Lens IDE for Kubernetes), was updated to v1.6.0. This version added force deletion and finalisation for Pods and other resources, new additional columns for Pods and Deployments lists, more details in the cluster role bindings views, and better support for Prometheus and VictoriaMetrics.

3. Podman Desktop, a developer-focused GUI for simplified container management (a CNCF Sandbox project), released 1.22. It introduced a new Explore Features section on the dashboard, an ability to switch Podman machines between rootless and rootful for macOS and Windows, a new option to apply YAML without creating a file locally, transparent proxy support, and an ARM64 Podman installer for Windows.

4. Headlamp, a Kubernetes web UI developed by the Kubernetes SIG, has seen its 0.36.0, featuring persistent table sorting, enhanced global search, support for EndpointSlice resources, support for running Headlamp embedded within Backstage, better capabilities for plugins, numerous Helm chart improvements, and more.

5. Keycloak, an identity and access management solution (a CNCF Incubating project), was updated to 26.4.0. This release introduced passkeys for passwordless user authentication, SPIFFE or Kubernetes service account tokens usage for Federated Client Authentication, simplified deployments across multiple availability zones, and support for the final specifications of FAPI 2.0 (Security Profile and Message Signing) and DPoP (Demonstrating Proof-of-Possession in OAuth 2.0).

6. Cozystack, a PaaS platform and framework for building clouds (a CNCF Sandbox project), released v0.37.0, bringing a brand-new GUI based on openapi-ui and aware of all allowed settings.

Old-school terminal users might enjoy getting a find-like experience for kubectl with this new project.

kubectl-find is a plugin for kubectl that helps you find Kubernetes resources based on various criteria and perform some actions. It allows you to:

- find resources by their name (regex), age, labels, and status;
- additionally, use a node name, image name, or the fact of being restarted when finding Pods;
- use custom jq filters for finding resources;
- execute one of these actions on the matched resources: print, patch, or delete.

Sharing another bunch of interesting Kubernetes-related articles recently spotted online:

1. "Beyond the surface - Exploring attacker persistence strategies in Kubernetes" by Rory McCune.

The goal of this talk is to lay out one attack path that attackers might use to retain and expand their access after an initial compromise of a Kubernetes cluster by getting access to an admin’s credentials. It doesn’t cover all the ways that attackers could do this, but provides one path and also hopefully illuminates some of the inner workings and default settings that attackers might exploit as part of their exploits.

2. "How our small company migrated from Docker Swarm to Kubernetes" by Miroslav Hrivnak, CORETEQ Technology.

As a small tech company with 20–30 people, we’ve gone through the natural evolution of infrastructure. From the days when one server and a few LXC containers were enough, to Docker and Docker Swarm, and finally to Kubernetes, which we now use not only in production but also for development and testing. In this article, I’d like to share why we migrated, the challenges we faced, and how we successfully moved from Docker Swarm to Kubernetes.

3. "k8s-1m Overview" by Ben Chess.

This is an effort to create a fully functional Kubernetes cluster with 1 million active nodes.

4. "Zero Trust for Kubernetes: Implementing Service Mesh Security" by Heinan Cabouly.

Let’s walk through a practical implementation of Zero Trust security using Istio on Amazon EKS. I’ll show you real-world configurations based on production Kubernetes environments.

5. "Clear Kubernetes namespace contents before deleting the namespace, or else" by Hongli Lai.

Our Kubernetes platform test suite creates namespaces with their corresponding contents, then deletes everything during cleanup. We noticed a strange problem: namespace deletion would sometimes get stuck indefinitely. The root cause was surprising — we had to clear the contents before deleting the namespace! We also learned that getting stuck isn’t the only issue that can occur if we don’t do this.

6. "Scaling Kubernetes at Mercado Libre with Karpenter and GitOps" by Juliano Marcos Martins, Mercado Libre.

This article explores how we’ve used Karpenter and GitOps to evolve our ecosystem (35,000 active microservices; approximately 30,000 daily deployments; around 120,000 pull requests per day), achieving automated provisioning, declarative governance, and large-scale cloud-native operations.
