Issue with creating Schema Registry object: "Register operation timed out; error code: 50002"

[abdelrahman-a-ibrahim]

Description

I am encountering an issue while deploying the Schema Registry image with imageTag 7.0.1 on Kubernetes. When attempting to create a new Schema Registry (SR) object, the operation fails with the following error message:

failed to create schema, 500, {"error_code":50002,"message":"Register operation timed out; error code: 50002"}

Steps to Reproduce

1. Deploy the Schema Registry image with imageTag 7.0.1 on Kubernetes.
2. Attempt to send a post request to create a new SR object.

Expected Behavior

The Schema Registry should successfully create the new SR object without errors.

Actual Behavior

The creation of the new SR object fails with a 500 error code and the message "Register operation timed out; error code: 50002".

Environment

• Schema Registry image: confluentinc/cp-schema-registry:7.0.1
• Kubernetes version: v1.28.9-eks-036c24b
• Kubernetes environment: EKS Cluster

I suppose it may be an issue to connect to your Kafka cluster. Also, it may be related to #3192

@abdelrahman-a-ibrahim are you running multiple replicas of schema registry? If yes the you need to change the advertised host for instance. In k8s, you can do like this

- name: SCHEMA_REGISTRY_HOST_NAME
   valueFrom:
      fieldRef:
        fieldPath: status.podIP
