Running a Spring Boot application inside a OpenShift Pod. To execute the readiness and liveness probe, I created an appropriate YAML file. However the Pod fails and responds that he was not able to pass the readiness check (after approximately 5 minutes).
My goal is to execute the readiness probe every 20 minutes. But I assume that it is failing because it adds up the initalDelaySeconds together with the periodSeconds. So I guess that the first check after the pod has been started will be executed after 22 minutes.
Following the related configuration of the readiness probe.
readinessProbe:
failureThreshold: 3
httpGet:
path: /actuator/health
port: 8080
scheme: HTTP
initialDelaySeconds: 120
periodSeconds: 1200
successThreshold: 1
timeoutSeconds: 60Is my assumption right? How to avoid it (Maybe increase the timeout regarding the kubelet)?
Your configuration is correct and the initialDelaySeconds and periodSeconds do not sum up. So, the first readinessProbe HTTP call will exactly in 2 min after you start your POD.
I would look for an issue in your app itself, first thing that comes to my mind is that your path is /actuator/health, shouldn't it be just /health? That is the default in case of Spring Boot Actuator.
If that doesn't help, then the best would be to debug it: exec into your container and use curl to check if your health endpoint works correctly (it should return HTTP Code 200).
