Kuberhealthy Configmap

Kuberhealthy uses a configmap for configuration parameters. This configmap is monitored for changes by Kuberhealthy. Upon a settings change being seen, all checks will be gracefully stopped and reloaded. For check-specific configuration, options are stored in the relevant khcheck resource (kubectl get khchecks).

The configuration file is mounted at `/etc/config’

Example Configmap

The following configmap contains all configurable options. If a configuration parameter is not needed, simply leave it blank or remove it from the configmap.
