Understanding Seldon Core

Seldon Core is an open-source platform designed to deploy machine learning models on Kubernetes. It provides a scalable and flexible way to manage and serve models, allowing for seamless integration into existing Kubernetes environments. Seldon Core supports a variety of machine learning frameworks and offers features like canary deployments, A/B testing, and advanced metrics.

Identifying the Symptom

When upgrading the Seldon Core model server, you might encounter issues such as deployment failures, unexpected behavior, or errors in the logs. These symptoms often manifest as incompatibility errors or version mismatch warnings during the upgrade process.

Exploring the Issue

Root Cause Analysis

The primary root cause of model server upgrade issues is often the incompatibility between the new and old versions of Seldon Core. This can occur if the upgrade procedures are not followed correctly or if there are breaking changes between versions. It's crucial to ensure that all components are compatible and that the upgrade path is supported.

Error Codes and Logs

During an upgrade, you might see error codes related to version mismatches or deprecated features. Checking the logs for specific error messages can provide insights into what went wrong. For example, you might encounter errors like Failed to pull image or Version mismatch detected.
