Hi,

Yeah that tutorial uses a readinessProbe

readinessProbe:
          exec:
            command:
            - /bin/bash
            - -c
            - /ready-probe.sh

If you change the image line back to image: gcr.io/google-samples/cassandra:v13 it should work. It uses this custom image https://github.com/kubernetes/examples/blob/master/cassandra/image/Dockerfile

This is the github repo for that tutorial https://github.com/kubernetes/examples/tree/master/cassandra

And since that's not our image so I'm going to close. If you need further help you could try asking over at Stack Overflow. Since these repos aren't really a user-help forum

I am using the correct image but getting the same error. My image: gcr.io/google-samples/cassandra:v13

The gcr.io/google-samples/cassandra image is not related to the images we build from the Dockerfiles in this repo. Please go to their docs repo or some other user help forum like StackOverflow.
