About Popeye

Popeye is a Kubernetes live cluster linter. It connects to a running cluster, examines the deployed resources and reports misconfigurations and potential problems, acting as a resource sanitizer rather than checking manifest files on disk.

The repository includes Grafana material, a Dockerfile for running it in a container and a krew manifest for installing it as a kubectl plugin. It suits cluster operators who want a quick health report on what is actually deployed.

Strengths

  • Checks live cluster state rather than static manifests
  • Can be installed as a kubectl plugin through krew
  • Can run as a container

Limitations

  • Needs access to a running Kubernetes cluster
  • Command-line only
