Heath check #309

Add liveness/readiness probe to deployment/statefulSets to ensure pods are up & running.

the-scott-hand commented 5 years ago

I would also like liveness/readiness probes for the deployment/statefulSets. I want to be able to verify that kafka is ready before my subscriber starts. I have been doing this using an init container to curl the http endpoint for other components readiness probes, so specifically I would like to see a readiness probe and liveness probe with an httpGet field like so: livenessProbe: httpGet: path: /healthz port: 8080 see: https://kubernetes.io/docs/tasks/configure-pod-container/configure-liveness-readiness-probes/

any word on this?

nicknezis commented 5 years ago

Ping. This seems like a very critical feature that is needed.

the-scott-hand commented 5 years ago

Looks like this kafka helm chart has readiness and liveliness probes implemented, https://github.com/helm/charts/blob/master/incubator/kafka/templates/statefulset.yaml#L87-L116

any updates on this?

This feature should be added. The pods despite failing to make connections will perpetually run if there are no liveness probes included.

I was in shock when I discovered this chart has no liveness/readiness check
