# AWS::ECR::ReplicationConfiguration ReplicationRule
<a name="aws-properties-ecr-replicationconfiguration-replicationrule"></a>

An array of objects representing the replication destinations and repository filters for a replication configuration.

## Syntax
<a name="aws-properties-ecr-replicationconfiguration-replicationrule-syntax"></a>

### JSON
<a name="aws-properties-ecr-replicationconfiguration-replicationrule-syntax.json"></a>

```
{
  "[Destinations](#cfn-ecr-replicationconfiguration-replicationrule-destinations)" : [ ReplicationDestination, ... ],
  "[RepositoryFilters](#cfn-ecr-replicationconfiguration-replicationrule-repositoryfilters)" : [ RepositoryFilter, ... ]
}
```

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

```
  [Destinations](#cfn-ecr-replicationconfiguration-replicationrule-destinations): 
    - ReplicationDestination
  [RepositoryFilters](#cfn-ecr-replicationconfiguration-replicationrule-repositoryfilters): 
    - RepositoryFilter

## Properties
<a name="aws-properties-ecr-replicationconfiguration-replicationrule-properties"></a>

`Destinations`  <a name="cfn-ecr-replicationconfiguration-replicationrule-destinations"></a>
An array of objects representing the destination for a replication rule.  
*Required*: Yes  
*Type*: Array of [ReplicationDestination](aws-properties-ecr-replicationconfiguration-replicationdestination.md)  
*Minimum*: `1`  
*Maximum*: `100`  
*Update requires*: [No interruption](https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/using-cfn-updating-stacks-update-behaviors.html#update-no-interrupt)

`RepositoryFilters`  <a name="cfn-ecr-replicationconfiguration-replicationrule-repositoryfilters"></a>
An array of objects representing the filters for a replication rule. Specifying a repository filter for a replication rule provides a method for controlling which repositories in a private registry are replicated.  
*Required*: No  
*Type*: Array of [RepositoryFilter](aws-properties-ecr-replicationconfiguration-repositoryfilter.md)  
*Minimum*: `0`  
*Maximum*: `100`
