Improving Application Availability with Pod Readiness Gates
Making sure your application running in Kubernetes is available and ready to serve traffic can be very easy with Pod liveness and readiness probes. However, not all application are built to be able to use probes or in some cases require more complex readiness checks which these probes simply cannot perform. Is there however any other solution, if Pod probes just aren't good enough?https://martinheinz.dev/blog/63

Performance evaluation of the autoscaling strategies vertical and horizontal using Kubernetes
Scalable applications may adopt horizontal or vertical autoscaling to dynamically provision resources in the cloud. To help to choose the best strategy, this work aims to compare the performance of horizontal and vertical autoscaling in Kubernetes. Through measurement experiments using synthetic load to a web application, the horizontal was shown more efficient, reacting faster to the load variation and resulting in a lower impact on the application response time.https://medium.com/@kewynakshlley/performance-evaluation-of-the-autoscaling-strategies-vertical-and-horizontal-using-kubernetes-42d9a1663e6b

kubectl-plugins
A collection of plugins for kubectl integration (for Kubectl versions >= 1.12.0)https://github.com/jordanwilson230/kubectl-plugins
flintlock
Flintlock is a service for creating and managing the lifecycle of microVMs on a host machine. Initially we will be supporting Firecracker.https://github.com/weaveworks-liquidmetal/flintlock
The primary use case for flintlock is to create microVMs on a bare-metal host where the microVMs will be used as nodes in a virtualized Kubernetes cluster. It is an essential part of Liquid Metal and will ultimately be driven by Cluster API Provider Microvm (coming soon).
helm-release-plugin
Helm3 plugin that pulls(re-creates) helm Charts from deployed releases, and updates values of deployed releases without the chart.https://github.com/JovianX/helm-release-plugin
cluster-api-k3s
Cluster API bootstrap provider k3s (CABP3) is a component of Cluster API that is responsible for generating a cloud-init script to turn a Machine into a Kubernetes Node; this implementation brings up k3s clusters instead of full kubernetes clusters.https://github.com/zawachte/cluster-api-k3s
