Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

DevOps Engineer here looking for something interesting to work on.
If your'e interested in open-source, I'd love to collaborate on doing some open source devops tools on free time. One of my latest ones is: https://github.com/jatalocks/kube-reqsizer

Kube-Reqsizer - open source VPA alternative for scaling your workloads
Hey r/kubernetes!Just wanted to share a personal project that might help some of you if you ever encounter this problem, or if you have better suggestions. A few months ago, I've starting developing Kube-Reqsizer. The problem I'm tackling here is Node under-utilization and its effect on cluster autoscaling.
- One way to manage #Kubernetes costs is to optimize resource usage by carefully planning and configuring resource limits and requests for each application; Ensuring that all resources are well-spent on idle or underutilized containers

Ask r/kubernetes: What are you working on this week?
Working on a controller to optimize pod requests. This is supposed to work with HPA and provide a simple VPA alternative https://github.com/jatalocks/kube-reqsizer
- GitHub - jatalocks/kube-reqsizer: A Kubernetes controller for automatically optimizing pod requests based on their continuous usage. VPA alternative that can work with HPA.

26 Top Kubernetes Tools
Metrics Server support is integrated with Kubectl. Its data can be accessed via the kubectl top command. Metrics Server is required to use Kubernetes auto-scaling features, including Horizontal Pod Autoscaler (HPA) and Vertical Pod Autoscaler (VPA), so it's a best practice addition to production clusters.

Upgrading Hundreds of Kubernetes Clusters
We use Cluster Autoscaler to automatically adjust the number of nodes (cluster size) based on your actual usage to ensure efficiency. Additionally, we deploy Vertical and Horizontal Pod Autoscalers to scale your applications' resources as their needs change automatically.

> * Hetzner: cheap, good service, the finest pets in the world, no cattle
You can absolutely do cattle with Hetzner. They support imaging and immutable infrastructure. They don't have a native auto scaling equivalent, but if you're using Kubernetes, they have a cluster autoscaler: https://github.com/kubernetes/autoscaler/blob/master/cluster...

Kubernetes(K8s) Autoscaler — a detailed look at the design and implementation of VPA
Here we take the VPA as a starting point to analyze the design and implementation principles of the VPA in Autoscaler. The source code for this article is based on Autoscaler HEAD fbe25e1.

Reducing Cloud Costs on Kubernetes Dev Envs
Autoscaling over EKS can be accomplished using either the cluster-autoscaler project or Karpenter. If you want to use Spot instances, consider using Karpenter, as it has better integrations with AWS for optimizing spot pricing and availability, minimizing interruptions, and falling back to on-demand nodes if no spot instances are available.

☸️ Managed Kubernetes : Our dev is on AWS, our prod is on OVH
Autoscaling is already provided on OVH, but we don't use it for now. Autoscaler has to be manually installed on the AWS/EKS cluster.

Anyone running Windows nodes in your clusters?
We have a default node group of Linux hosts, but there's a secondary nodegroup of Windows hosts that is typically scaled down to 0. When a team's build runs, a pod is scheduled based on their definition. Cluster-autoscaler will check the nodeSelector and automatically spin up a node from that nodegroup if necessary.
