# Invoke ModelLifeCycle using the Amazon CLI examples
<a name="model-registry-staging-construct-cli"></a>

You can use the Amazon CLI tool to manage your Amazon resources. A few Amazon CLI commands include [search](https://awscli.amazonaws.com/v2/documentation/api/latest/reference/cloudsearchdomain/search.html) and [list-actions](https://awscli.amazonaws.com/v2/documentation/api/latest/reference/fis/list-actions.html). The following page will provide examples on how to use `ModelPackage` while using these commands. For information and examples on setting up your stage construct, see [Set up Staging Construct Examples](model-registry-staging-construct-set-up.md).

The examples on this page uses the following variables.
+ `{{region}}` is the region that your model package exists in.
+ `{{stage-name}}` is the name of your defined stage.
+ `{{stage-status}}` is the name of your defined stage status.

The following are example Amazon CLI commands using ModelLifeCycle.

Search for your model packages with a {{stage-name}} you have already defined.

```
aws sagemaker search --region '{{region}}' --resource ModelPackage --search-expression '{"Filters": [{"Name": "ModelLifeCycle.Stage","Value": "{{stage-name}}"}]}'
```

List the actions associated with `ModelLifeCycle`.

```
aws sagemaker list-actions --region '{{region}}' --action-type ModelLifeCycle
```

Create a model package with ModelLifeCycle.

```
aws sagemaker create-model-package --model-package-group-name '{{model-package-group-name}}' --source-uri '{{source-uri}}' --region '{{region}}' --model-life-cycle '{"Stage":"{{stage-name}}", "StageStatus":"{{stage-status}}", "StageDescription":"{{Your Staging Comment}}"}' 
```

Update a model package with ModelLifeCycle.

```

```

Search via the ModelLifeCycle field.

```
aws sagemaker search --region '{{region}}' --resource ModelPackage --search-expression '{"Filters": [{"Name": "ModelLifeCycle.Stage","Value": "{{stage-name}}"}]}'
