Frequently Asked Questions

What is the difference between the liveness and readiness checks?

The liveness check filters out the StartupHostedServiceHealthCheck by returning false in the HealthCheckOptions.Predicate (for more information, see Filter health checks) The readiness check uses all registered checks with the 'ready' tag. The Predicate excludes all checks and return a 200-Ok.

Where can I view the data from the readiness health checks?

You can also access the /health/readyendpoint by visiting the http://localhost:9080/health/readyURL to view the data from the readiness health checks. Similarly, access the /health/liveendpoint by visiting the http://localhost:9080/health/liveURL to view the data from the liveness health checks.

How do I check the readiness and liveness of a pod?

Open the deployment in the Helm charts folder. There you can see the liveness and readiness probe already. As you can see, the liveness probe checks the /health endpoint and the readiness probe the /ready endpoint. Since the /ready endpoint doesn’t exist, the pod won’t be able to start.

What are readiness and liveness probes in OpenShift?

Kubernetes and, therefore, OpenShift, offers two types of probes: liveness probes and readiness probes. We use liveness probes to know when it's necessary to restart a container. OpenShift restarts the pod when the health check fails and the pod becomes unavailable.
