--- title: How can I use Kubernetes liveness and readiness for service health check with Istio Auth enabled? weight: 40 --- If Istio Auth is enabled, http and tcp health check from kubelet will not work since they do not have Istio Auth issued certs. A workaround is to use a [liveness command](https://kubernetes.io/docs/tasks/configure-pod-container/configure-liveness-readiness-probes/#define-a-liveness-command) for health check, e.g., one can install curl in the service pod and curl itself within the pod. The Istio team is actively working on a solution. An example of readinessProbe: ```yaml livenessProbe: exec: command: - curl - -f - http://localhost:8080/healthz # Replace port and URI by your actual health check initialDelaySeconds: 10 periodSeconds: 5 ```
