This page explains how to add versioning information to CustomResourceDefinitions, to indicate the stability level of your CustomResourceDefinitions or advance your API to a new version with conversion between API representations. It also describes how to upgrade an object from one version to another. Before you begin You need to have a Kubernetes cluster, and the kubectl command-line tool must be configured to communicate with your cluster. It is recommended to run this tutorial on a cluster...| Kubernetes

Supporting real-time data streaming enables our internal users to build intelligent applications and services, a crucial aspect of continuously out-serving our community. Read this article to understand our journey of building a real-time data streaming platform from pure Infrastructure-as-Code towards a more sophisticated control plane, and the benefits of this solution.| Grab Tech

Last month, we announced our new GitOps Environment dashboard that finally allows you to promote Argo CD applications easily between different environments. We have seen why this dashboard is groundbreaking (compared to vanilla Argo CD) as it allows you to easily promote application and configuration changes between environments while providing rich information about your applications […]| Codefresh

In our ongoing SIG Spotlight series, we dive into the heart of the Kubernetes project by talking to the leaders of its various Special Interest Groups (SIGs). This time, we focus on SIG Apps, the group responsible for everything related to developing, deploying, and operating applications on Kubernetes. Sandipan Panda (DevZero) had the opportunity to interview Maciej Szulik (Defense Unicorns) and Janet Kuo (Google), the chairs and tech leads of SIG Apps.| Kubernetes Contributors

Tools such as Prometheus and OpenTelemetry help us monitor the health, performance, and availability of our complex distributed systems. Both are open source projects under the Cloud Native Computing Foundation (CNCF) umbrella – but what role does each play in observability? OpenTelemetry (OTel for short), is a vendor-neutral open standard for instrumenting, generating, collecting, and exporting telemetry data. Prometheus is a fixture of the observability landscape, widely relied upon for m...| OpenTelemetry

Kubernetes has always been evolving, and this progress provides more flexibility and extensibility to developers and operations teams. one feature I came across is Custom Resource Definition (CRDs). this allows users to create their own new resource ...| DEV-ALPHARM
This page shows how to install a custom resource into the Kubernetes API by creating a CustomResourceDefinition. Before you begin You need to have a Kubernetes cluster, and the kubectl command-line tool must be configured to communicate with your cluster. It is recommended to run this tutorial on a cluster with at least two nodes that are not acting as control plane hosts. If you do not already have a cluster, you can create one by using minikube or you can use one of these Kubernetes playgro...| Kubernetes

The Kubernetes API lets you query and manipulate the state of objects in Kubernetes. The core of Kubernetes' control plane is the API server and the HTTP API that it exposes. Users, the different parts of your cluster, and external components all communicate with one another through the API server.| Kubernetes

Since the very beginning of Kubernetes, the topic of persistent data and how to address the requirement of stateful applications has been an important topic. Support for stateless deployments was natural, present from the start, and garnered attention, becoming very well-known. Work on better support for stateful applications was also present from early on, with each release increasing the scope of what could be run on Kubernetes. Message queues, databases, clustered filesystems: these are so...| www.kubernetes.dev
The Kubernetes community has been signing their container image-based artifacts since release v1.24. While the graduation of the corresponding enhancement from alpha to beta in v1.26 introduced signatures for the binary artifacts, other projects followed the approach by providing image signatures for their releases, too. This means that they either create the signatures within their own CI/CD pipelines, for example by using GitHub actions, or rely on the Kubernetes image promotion process to ...| Kubernetes
FEATURE STATE: Kubernetes v1.21 [stable] This page shows how to limit the number of concurrent disruptions that your application experiences, allowing for higher availability while permitting the cluster administrator to manage the clusters nodes. Before you begin Your Kubernetes server must be at or later than version v1.21. To check the version, enter kubectl version. You are the owner of an application running on a Kubernetes cluster that requires high availability.| Kubernetes

Often times, especially during development of software that talks to the kubernetes API server, I actually find myself looking for a detailed kubernetes API specification. And no, I am not talking about the official kubernetes API reference which mainly reveals core object models. I am also interested in the specific API paths, the possible headers, query parameters and responses.| jonnylangefeld.com
If you have written a Kubernetes controller, you are likely familiar with controller-runtime, or at least client-go. controller-runtime is a framework for building controllers that allows consumers to setup multiple controllers that are all handled under a controller manager. Behind the the scenes, controller-runtime is using client-go to communicate with the Kubernetes API server to watch for changes on resources and pass them along to the relevant controllers. It handles a number of aspects...| danielmangum.com
If I was to explain LLVM in a painfully simple manner, I might say something like: “LLVM is a framework that allows you to define a syntax for interacting with computers, and instantly have it work for all computers”. This description does a colossal disservice to the scope of the project, but it serves to illustrate the basic idea: there are many languages (frontends) and many CPU architectures (backends) and we don’t want to re-implement every translation permutation.| danielmangum.com
For folks familiar with Crossplane, you likely know that we adopt the design practice of using interfaces over implementations as frequently as possible. Even if we begin with an implementation, such as the current composition engine, we make sure to consider a future with potentially many implementations for the same functionality. One of the places where we have taken advantage of Kubernetes’ similar approach to interfaces is in how we cache Crossplane package images.| danielmangum.com
This post references the Kubernetes codebase at commit d92a443ca7 and kube-openapi at commit ee342a809c, but should remain mostly applicable for an extended period of time barring any massive refactor to Kubernetes internals. This is also intended to be a very active read and a reference to come back to over time. There are a lot of links to source code that is not embedded because the post would have become even more unwieldy than it already is.| danielmangum.com
