Liveness and health services

All components of nevisDetect are providing so-called liveness and health services. These services are designed for an automated management system of nevisDetect, such as Kubernetes. Deployment to Kubernetes is only supported via nevisAdmin 4. The status of a component is determined by the status of all resources used by the system. This section shows the example responses of the health service for the different components.
