Developer News

Staging Images are migrating off GCR since Google Container Registry is shutting down in March. If you manage a Staging repo, and want something to happen other than just moving to Artifact Registry, contact K8s-Infra very soon. Users should already be using registry.k8s.io and are unaffected … right?

Code of Conduct Committee nominations are closing on January 31.

Happy Year of the Snake!

128546: add PodReplacementPolicy for Deployments: terminating pods

A new status field, .status.terminatingReplicas, has been added to Deployments and ReplicaSets to improve visibility into terminating pods. This change is a prerequisite for introducing PodReplacementPolicy in Deployments, which will provide more control over pod updates. The new field is available when the DeploymentPodReplacementPolicy feature gate is enabled.

Black box vs white box observability in Kubernetes, with Artem Lajko

https://ku.bz/9sGxhmm8s

Platform Engineer Artem Lajko breaks down observability into three distinct layers and explains how tools like Prometheus, Grafana, and Falco serve different purposes. He also shares practical insights on implementing the right level of monitoring based on team requirements and capabilities.

You will learn:

How to implement the three-layer model (external, internal, and OS-level) and why each layer serves different stakeholders

How to choose and scale observability tools using a label-based approach (low, medium, high)

How to manage observability costs by collecting only relevant metrics and logs

From UX to API: Mastering Platform Validations with Kubernetes Validating Admission Policies

In this video, we dive deep into the importance of validations in Internal Developer Platforms and how they enhance user experience. We explore different examples, including Web UI, custom CLI scripts, and Kubernetes-based tools like Argo CD and kubectl, to distinguish between UX validations and real policies. Learn how to implement reliable validations using Kubernetes Admission Controller Webhooks and ensure only valid requests are processed by your API. We also discuss the role of tools like Crossplane for creating custom abstractions and enforcing policies.
