Stale container image in Example: Deploying Cassandra with a StatefulSet #45351

Open dshebib opened 8 months ago

dshebib commented 8 months ago

This is a Bug Report

Problem The image in https://kubernetes.io/docs/tutorials/stateful-application/cassandra/#using-a-statefulset-to-create-a-cassandra-ring is out-of-date, causing cqlsh (the core commandline tool for cassandra) to fail with an error about an invalid python interpreter. Though the Kubernetes statefulset works as intended and the cluster runs properly, this makes the example hard to explore for intedned functionality. It could be improved by having an up-to-date image so that basic commands can be run within the started pods.

Proposed solution Update the gcr.io/google-samples/cassandra:v13 image or use an up-to-date Dockerhub Cassandra image and update the readiness probe as needed.

Page to Update: https://kubernetes.io/docs/tutorials/stateful-application/cassandra

It sounds more like an improvment that would need to made for this.
