KubeVirt is a virtual machine management add-on for Kubernetes. The aim is to provide a common ground for virtualization solutions on top of Kubernetes.

We recently migrated all of our infrastructure metrics from StatsD to Prometheus and are very pleased with the results. The migration was a ton of work and we learned a lot along the way. This post aims to shed some light on why we migrated to Prometheus, as well as outline some of the technical challenges we faced during the process.

At incident.io, we run an on-call product. Our customers need to be sure that when their systems go wrong, we’ll tell them about it—high availability is a core requirement for us. To achieve the level of reliability that’s essential to our customers, excellent observability (o11y) is one of the most important tools in our belt.

KubeAdmiral is a multi-cluster management system for Kubernetes, developed from Kubernetes Federation v2. Kubernetes Federation v2 allows users to manage Kubernetes resources across multiple clusters through the use of federated types such as FederatedDeployment, FederatedReplicaSet, FederatedSecret, etc. KubeAdmiral extends the Kubernetes Federation v2 API, providing compatibility with the Kubernetes native API and more powerful resource management capabilities.

JET Pilot is an open-source K8s IDE. It was created out of frustration, as all "good-looking" K8s IDEs went commercial. Power-users nowaday resort to tools like k9s, which works great, but heavily relies on keyboard input. JET Pilot tries to overcome these usability challenges.

How many of your dev/preview pods stay on during weekends? Or at night? It's a waste of resources! And money! But fear not, kube-green is here to the rescue.

kube-green is a simple k8s addon that automatically shuts down (some of) your resources when you don't need them.

KubeDNS Shepherd is a Kubernetes controller that manages the DNS configuration of workloads, ensuring an efficient and reliable way to configure DNS within your Kubernetes cluster. This project is essential for those looking to optimize DNS resolutions and configurations within their Kubernetes environments.

kctxsync is a command-line tool designed to synchronize the certificate and key data from a remote Kubernetes cluster's kubeconfig file to your local kubeconfig. It is particularly useful for updating the local kubeconfig when certificates or keys have changed in the remote cluster, ensuring that your local environment is always in sync with the remote server.

K8up is a Kubernetes backup operator based on Restic that will handle PVC and application backups on a Kubernetes or OpenShift cluster.

Acceleration Service provides a general service to Harbor with the ability to automatically convert user images to accelerated images. When a user does something such as artifact push, Harbor will request the service to complete the corresponding image conversion through its integrated Nydus, eStargz, etc. drivers.

Start with a Template for a popular service like Airflow, Kafka, or PostgreSQL and CNDI will help you deploy it on your own infrastructure - just as easily as you can sign up for a cloud-based Platform as a Service.

Kubero [pronounced: Kube Hero] is a self-hosted PaaS (Platform as a Service) that allows any developer to deploy their application on Kubernetes without specialized knowledge. Kubero follows the principles of 12-factor apps. It is possible to run apps based on existing containers or from source code.

This is a fork of awesome Kubernetes The Hard Way by Kelsey Hightower and is geared towards using it on AWS.

One of the features of Kubernetes security, is its flexible model. This allows cluster operators to have multiple Authentication or Authorization modes running covering a number of use cases. This does introduce some complexity though both in terms of operation and also in terms of reviewing or auditing rights.

The most common case here is cloud managed Kubernetes where, in addition to the in-built RBAC authorization, you’ll often find that there’s a webhook authorization mode enabled as well to allow for integration with the cloud provider’s IAM system.

Implementing Kubernetes Operators for Streamlined Application Management

Getting started with Kubernetes might seem like a daunting task at first, but getting a basic ephemeral cluster up and running with tools like minikube, kind, or k3d is quite straightforward if you follow their documentation.

In this article we’ll explore how to bootstrap a more permanent, or production grade, Kubernetes cluster using k3s. Other tools like kubeadm, k0s, microk8s, or kubespray (which uses kubeadm under the hood) are also available.
