# AWS::ECR::SigningConfiguration Rule
<a name="aws-properties-ecr-signingconfiguration-rule"></a>

A signing rule that specifies a signing profile and optional repository filters. When an image is pushed to a matching repository, a signing job is created using the specified profile.

## Syntax

  "[RepositoryFilters](#cfn-ecr-signingconfiguration-rule-repositoryfilters)" : {{[ RepositoryFilter, ... ]}},
  "[SigningProfileArn](#cfn-ecr-signingconfiguration-rule-signingprofilearn)" : {{String}}
}
```

### YAML
<a name="aws-properties-ecr-signingconfiguration-rule-syntax.yaml"></a>

  [RepositoryFilters](#cfn-ecr-signingconfiguration-rule-repositoryfilters): {{
    - RepositoryFilter}}
  [SigningProfileArn](#cfn-ecr-signingconfiguration-rule-signingprofilearn): {{String}}
