kove is a Go library typically used in Performance Management, Monitoring, Prometheus applications. kove has no bugs, it has no vulnerabilities, it has a Permissive License and it has low support. You can download it from GitHub.

Open Policy Agent provide the fearsome-but-trustworthy gatekeeper, which allows for admission control of Kubernetes manifests being submitted to the API. This is really nice and allows administrators to control the manifests coming in as fine-grained as they please. However, administrators may not always want to take direct action (such as denial) on manifests arriving at the API. This is where kove comes in. It allows administrators of Kubernetes clusters to define Rego policies that they want to flag violations for by exposing a Prometheus metric. Some example use cases include monitoring the use of deprecated APIs, unwanted docker images, or container vars containing strings like API_KEY, etc. Administrators can craft dashboards or alerts when such conditions are observed to better expose this information to users. kove is built on an informer model, rather than admission control - so, it works on any existing objects in your cluster, instead of evaluating them when they arrive at the API (upon create/update). This means it'll expose policy violators that may otherwise go unnoticed if they're not updated often.
