kubeeye v1.0 releases: audit tool for Kubernetes
kubeeye
KubeEye is an audit tool for Kubernetes to discover Kubernetes resources (by OPA ), cluster components, cluster nodes (by Node-Problem-Detector), and other configurations that are meeting with best practices and giving suggestions for modification.
KubeEye supports custom audit rules and plugins installation. Through KubeEye Operator, you can view audit results and modify suggestions on the website.
Architecture
KubeEye gets cluster resource details by the Kubernetes API, audits the resource configurations by audit rules and plugins, and generates audit results. See Architecture for details.
What KubeEye can do
- KubeEye audits cluster resources with Kubernetes best practices, to make cluster stable.
- KubeEye can find problems of your cluster control plane, including kube-apiserver/kube-controller-manager/etcd, etc.
- KubeEye helps you detect all kinds of node problems, including memory/cpu/disk pressure, unexpected kernel error logs, etc.
