KubeLB is a project by Kubermatic, it is a Kubernetes native tool, responsible for centrally managing load balancers for Kubernetes clusters across multi-cloud and on-premise environments.

crik is a project that aims to provide checkpoint and restore functionality for Kubernetes pods mainly targeted for node shutdown and restart scenarios. It is a command wrapper that, under the hood, utilizes criu to checkpoint and restore process trees in a Pod.

The generic-device-plugin enables allocating generic Linux devices, such as serial devices, the FUSE device, or video cameras, to Kubernetes Pods. This allows devices that don't require special drivers to be advertised to the cluster and scheduled, enabling various use-cases, e.g.:

- accessing video and sound devices;
- running IoT applications, which often require access to hardware devices; and
- mounting FUSE filesysems without privileged.

Get cute Tortoises into your Kubernetes garden and say goodbye to the days optimizing your rigid autoscalers.

Tortoise is still in the early stage and we recommend evaluating its behaviour with your services in your development environment carefully.

Kompare is a Go CLI runner for comparing two clusters. This software compares two Kubernetes clusters using kubeconfig to connect to them and compare existing objects in the two clusters based on flexible criteria passed via the command line.

KubeFox is an SDK, platform and infrastructure to enable rapid construction and deployment of secure and robust applications for Kubernetes, and which drastically reduces bureaucracy and burdensome DevOps activities.

Bare metal servers are awesome. They let you pick where to run your software and how to deploy it. You get full control to make the most of the server's resources. No limits, no compromises. That's real freedom.

Viking makes it easier to work with them.

In this article we discuss three open source load-balancer controllers that can be used with any distribution of Kubernetes.

CAP? Again? Still?

Put your DevOps skills to the test with our hands-on capstone project. Designed for anyone interested in gaining practical experience, this project challenges you to integrate AWS, Terraform, Kubernetes, GitHub Actions, ArgoCD, Datadog, and PagerDuty to build and manage a production-like environment. Showcase your ability to create a complete, real-world solution by building cloud infrastructure, implementing observability, developing CI/CD pipelines, and managing incidents.

Kardinal is a framework for creating extremely lightweight ephemeral development environments within a shared Kubernetes cluster. In Kardinal, an environment is called a "flow" because it represents a path that a request takes through the cluster. Versions of services that are under development are deployed on-demand, and then shared across all development work that depends on that version. Read more about Kardinal in our docs.

grpcmd is a simple, easy-to-use, and developer-friendly CLI tool for gRPC.

This blog post describes the case study of how we diagnosed, root caused and then mitigated a performance issue in one of our applications in Flipkart. As part of this journey, we describe the different tools (eBPF and traditional) that can debug performance issues.

How Chick-fil-A provides observability for 2,800+ K8s clusters

In the early days of Kubernetes adoption, single-cluster deployments were the norm, offering a straightforward approach to managing applications and services. As the adoption of Kubernetes expanded, the limitations of single-cluster models surfaced. The increasing demand for Kubernetes clusters requires a shift to multicluster deployments and an innovative Hosted Control Plane architecture.

Learn how easy it is to manage multiple Helm Charts from one deployment project using Kluctl.

In this article we’ll create a two-node cluster with one control-plane node and one worker node as a proof-of-concept. As an extra challenge we’ll also take a look at how to do PCIe passthrough for the worker node.
