Seldon Core is an open-source platform designed to deploy machine learning models on Kubernetes. It provides a robust infrastructure for scaling and managing models in production, ensuring that they are served efficiently and reliably. By leveraging Kubernetes, Seldon Core allows for seamless integration with existing cloud-native environments, making it a popular choice for organizations looking to operationalize their machine learning workflows.
One common issue users encounter with Seldon Core is when the ingress is not routing traffic to the deployed models. This symptom is typically observed when requests to the model endpoint do not receive a response or result in a 404 error. This can be frustrating as it prevents the model from being accessed by external clients.
The root cause of ingress not routing traffic often lies in the misconfiguration of the ingress resource. In Kubernetes, an ingress resource defines rules for routing external HTTP/S traffic to services within the cluster. If this resource is not configured correctly, or if necessary annotations are missing, the traffic will not be routed as expected.
To resolve the ingress routing issue, follow these detailed steps:
Check the ingress resource configuration to ensure that the host and path are correctly defined. Use the following command to view the ingress resource:
kubectl get ingress -n <namespace> -o yaml
Ensure that the spec.rules section correctly matches the expected host and path for your service.
Annotations are often required by ingress controllers to enable specific features or behaviors. Ensure that the necessary annotations are present. For example, if using NGINX Ingress Controller, you might need:
annotations:
nginx.ingress.kubernetes.io/rewrite-target: /
Refer to the NGINX Ingress Controller Annotations documentation for more details.
Ensure that the ingress controller is installed and running correctly. Check the status of the ingress controller pods:
kubectl get pods -n ingress-nginx
If the pods are not running, refer to the NGINX Ingress Controller Deployment Guide for installation instructions.
By following these steps, you should be able to resolve the ingress routing issue in Seldon Core. Proper configuration of the ingress resource and ensuring the ingress controller is functioning correctly are key to successfully routing traffic to your deployed models.
