Model Chain - Ready Check

We will check the readiness of the Pipeline after every change to model and pipeline.

Kubernetes Resource Example

Note: The Seldon CLI allows you to view information about underlying Seldon resources and make changes to them through the scheduler in non-Kubernetes environments. However, it cannot modify underlying manifests within a Kubernetes cluster. Therefore, using the Seldon CLI for control plane operations in a Kubernetes environment is not recommended. For more details, see Seldon CLI.
