# AWS::CodePipeline::Pipeline ArtifactStoreMap
<a name="aws-properties-codepipeline-pipeline-artifactstoremap"></a>

A mapping of `artifactStore` objects and their corresponding AWS Regions. There must be an artifact store for the pipeline Region and for each cross-region action in the pipeline.

**Note**  
You must include either `artifactStore` or `artifactStores` in your pipeline, but you cannot use both. If you create a cross-region action in your pipeline, you must use `artifactStores`.

## Syntax
<a name="aws-properties-codepipeline-pipeline-artifactstoremap-syntax"></a>

To declare this entity in your CloudFormation template, use the following syntax:

### JSON
<a name="aws-properties-codepipeline-pipeline-artifactstoremap-syntax.json"></a>

```
{
  "[ArtifactStore](#cfn-codepipeline-pipeline-artifactstoremap-artifactstore)" : ArtifactStore,
  "[Region](#cfn-codepipeline-pipeline-artifactstoremap-region)" : String
}
```

### YAML
<a name="aws-properties-codepipeline-pipeline-artifactstoremap-syntax.yaml"></a>

```
  [ArtifactStore](#cfn-codepipeline-pipeline-artifactstoremap-artifactstore): 
    ArtifactStore
  [Region](#cfn-codepipeline-pipeline-artifactstoremap-region): String
```

## Properties
<a name="aws-properties-codepipeline-pipeline-artifactstoremap-properties"></a>

`ArtifactStore`  <a name="cfn-codepipeline-pipeline-artifactstoremap-artifactstore"></a>
Represents information about the S3 bucket where artifacts are stored for the pipeline.  
You must include either `artifactStore` or `artifactStores` in your pipeline, but you cannot use both. If you create a cross-region action in your pipeline, you must use `artifactStores`.
