Kubetail enables you to aggregate logs from multiple pods into one stream. It is same as running kubectl logs -f but for multiple pods. Getting logs from multiple pods is often required and that's where Kubetail helps developers.

Kubetail is a simple bash script that allows you to tail multiple pods simultaneously in an easy manner.



Kube-state-metrics enables you to get metrics based on the current state of Kubernetes native resources. It is a simple service that listens to the Kubernetes API server and generates metrics about the state of the objects. A few example metrics captured by kube-state-metrics are:

  • kube_pod_container_status_restarts_total
  • kube_deployment_status_replicas
  • kube_pod_container_resource_requests
  • kube_pod_container_resource_limits



Kubeval is used to validate Kubernetes configuration files. It can be used locally as part of the development workflow as well as in CI pipelines.

Kubeval validates configuration files using schemas generated from the Kubernetes OpenAPI specification.



This is a handy tool that lets you add the current Kubernetes context and namespace configured onΒ kubectlΒ to your Bash/Zsh prompt strings (i.e. theΒ $PS1). It can be installed using Homebrew package manager.



Kubectx provides an easier and a faster way to switch between clusters back and forth.



Kubecost can be used to gain visibility into current and historical Kubernetes spend and resource allocation. The models prepared by Kubecost provide cost transparency in Kubernetes environments that support multiple applications, teams, departments, etc.
