About Kuberhealthy

Kuberhealthy is a Kubernetes operator for synthetic monitoring and continuous validation. It schedules, tracks, and manages short-lived pods that run checks against your cluster or applications, and it ships the results as metrics to Prometheus. It is written in Go and released under the Apache-2.0 license.

Checks are defined through the HealthCheck custom resource definition, so monitoring logic becomes Kubernetes manifests that can be shipped alongside an application. Because each check runs in a container, it can be written in any language, such as Go, Python, Rust, or bash, and can run multi-step workflows that mimic a real user: logging in, creating a record, verifying it, and cleaning it up.

Its topics place it in continuous testing and delivery workflows as well as monitoring. Kuberhealthy suits platform and SRE teams that want end-to-end confidence that their clusters and services actually work, beyond simple resource metrics.
