### Model Chain - Ready Check

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

```bash
cat ./pipelines/tfsimples.yaml
```

```yaml
apiVersion: mlops.seldon.io/v1alpha1

metadata:
  name: tfsimples

    - name: tfsimple2

      tensorMap:
        tfsimple1.outputs.OUTPUT0: INPUT0
        tfsimple1.outputs.OUTPUT1: INPUT1
  output:
    steps:
    - tfsimple2

```

### Kubernetes Resource Example

{% hint style="info" %}
**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](/seldon-core-2/resources/apis/cli.md).
{% endhint %}

```python
import os
os.environ["NAMESPACE"] = "seldon-mesh"

```python
MESH_IP=!kubectl get svc seldon-mesh -n ${NAMESPACE} -o jsonpath='{.status.loadBalancer.ingress[0].ip}'

# Agent Instructions: Querying This Documentation

If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter:

```
GET https://docs.seldon.ai/seldon-core-2/user-guide/examples/pipeline-ready-and-metadata.md?ask=<question>
```

The question should be specific, self-contained, and written in natural language.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
