# AWS::Omics::Workflow RegistryMapping
<a name="aws-properties-omics-workflow-registrymapping"></a>

If you are using the ECR pull through cache feature, the registry mapping maps between the ECR repository and the upstream registry where container images are pulled and synchronized.

## Syntax
<a name="aws-properties-omics-workflow-registrymapping-syntax"></a>

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

### JSON
<a name="aws-properties-omics-workflow-registrymapping-syntax.json"></a>

```
{
  "[EcrAccountId](#cfn-omics-workflow-registrymapping-ecraccountid)" : String,
  "[EcrRepositoryPrefix](#cfn-omics-workflow-registrymapping-ecrrepositoryprefix)" : String,
  "[UpstreamRegistryUrl](#cfn-omics-workflow-registrymapping-upstreamregistryurl)" : String,
  "[UpstreamRepositoryPrefix](#cfn-omics-workflow-registrymapping-upstreamrepositoryprefix)" : String
}
```

### YAML
<a name="aws-properties-omics-workflow-registrymapping-syntax.yaml"></a>

```
  [EcrAccountId](#cfn-omics-workflow-registrymapping-ecraccountid): String
  [EcrRepositoryPrefix](#cfn-omics-workflow-registrymapping-ecrrepositoryprefix): String
  [UpstreamRegistryUrl](#cfn-omics-workflow-registrymapping-upstreamregistryurl): String
