## Request Parameters
<a name="API_UpdateRepositoryCreationTemplate_RequestParameters"></a>

For information about the parameters that are common to all actions, see [Common Parameters](CommonParameters.md).

The request accepts the following data in JSON format.

 ** [appliedFor](#API_UpdateRepositoryCreationTemplate_RequestSyntax) **   <a name="ECR-UpdateRepositoryCreationTemplate-request-appliedFor"></a>
Updates the list of enumerable strings representing the Amazon ECR repository creation scenarios that this template will apply towards. The supported scenarios are `PULL_THROUGH_CACHE`, `REPLICATION`, and `CREATE_ON_PUSH`   
Type: Array of strings  
Valid Values: `REPLICATION | PULL_THROUGH_CACHE | CREATE_ON_PUSH`   
Required: No

 ** [customRoleArn](#API_UpdateRepositoryCreationTemplate_RequestSyntax) **   <a name="ECR-UpdateRepositoryCreationTemplate-request-customRoleArn"></a>
The ARN of the role to be assumed by Amazon ECR. This role must be in the same account as the registry that you are configuring. Amazon ECR will assume your supplied role when the customRoleArn is specified. When this field isn't specified, Amazon ECR will use the service-linked role for the repository creation template.  
Type: String  
Length Constraints: Maximum length of 2048.  
Required: No

 ** [description](#API_UpdateRepositoryCreationTemplate_RequestSyntax) **   <a name="ECR-UpdateRepositoryCreationTemplate-request-description"></a>
A description for the repository creation template.  
Type: String  
Length Constraints: Maximum length of 256.  
Required: No

 ** [encryptionConfiguration](#API_UpdateRepositoryCreationTemplate_RequestSyntax) **   <a name="ECR-UpdateRepositoryCreationTemplate-request-encryptionConfiguration"></a>
The encryption configuration to associate with the repository creation template.  
Type: [EncryptionConfigurationForRepositoryCreationTemplate](API_EncryptionConfigurationForRepositoryCreationTemplate.md) object  
Required: No

 ** [imageTagMutability](#API_UpdateRepositoryCreationTemplate_RequestSyntax) **   <a name="ECR-UpdateRepositoryCreationTemplate-request-imageTagMutability"></a>
Updates the tag mutability setting for the repository. If this parameter is omitted, the default setting of `MUTABLE` will be used which will allow image tags to be overwritten. If `IMMUTABLE` is specified, all image tags within the repository will be immutable which will prevent them from being overwritten.  
Type: String  
Valid Values: `MUTABLE | IMMUTABLE | IMMUTABLE_WITH_EXCLUSION | MUTABLE_WITH_EXCLUSION`   
Required: No

 ** [imageTagMutabilityExclusionFilters](#API_UpdateRepositoryCreationTemplate_RequestSyntax) **   <a name="ECR-UpdateRepositoryCreationTemplate-request-imageTagMutabilityExclusionFilters"></a>
A list of filters that specify which image tags should be excluded from the repository creation template's image tag mutability setting.  
Type: Array of [ImageTagMutabilityExclusionFilter](API_ImageTagMutabilityExclusionFilter.md) objects  
Array Members: Minimum number of 1 item. Maximum number of 5 items.  
Required: No

 ** [lifecyclePolicy](#API_UpdateRepositoryCreationTemplate_RequestSyntax) **   <a name="ECR-UpdateRepositoryCreationTemplate-request-lifecyclePolicy"></a>
Updates the lifecycle policy associated with the specified repository creation template.  
Type: String  
Length Constraints: Minimum length of 0. Maximum length of 30720.  
Required: No

 ** [prefix](#API_UpdateRepositoryCreationTemplate_RequestSyntax) **   <a name="ECR-UpdateRepositoryCreationTemplate-request-prefix"></a>
The repository namespace prefix that matches an existing repository creation template in the registry. All repositories created using this namespace prefix will have the settings defined in this template applied. For example, a prefix of `prod` would apply to all repositories beginning with `prod/`. This includes a repository named `prod/team1` as well as a repository named `prod/repository1`.  
To apply a template to all repositories in your registry that don't have an associated creation template, you can use `ROOT` as the prefix.  
Type: String  
Length Constraints: Minimum length of 1. Maximum length of 256.  
Pattern: `^([a-z0-9]+((\.|_|__|-+)[a-z0-9]+)*(\/[a-z0-9]+((\.|_|__|-+)[a-z0-9]+)*)*\/?|ROOT)$`   
Required: Yes

 ** [repositoryPolicy](#API_UpdateRepositoryCreationTemplate_RequestSyntax) **   <a name="ECR-UpdateRepositoryCreationTemplate-request-repositoryPolicy"></a>
Updates the repository policy created using the template. A repository policy is a permissions policy associated with a repository to control access permissions.   
Type: String  
Length Constraints: Minimum length of 0. Maximum length of 10240.  
Required: No

 ** [resourceTags](#API_UpdateRepositoryCreationTemplate_RequestSyntax) **   <a name="ECR-UpdateRepositoryCreationTemplate-request-resourceTags"></a>
The metadata to apply to the repository to help you categorize and organize. Each tag consists of a key and an optional value, both of which you define. Tag keys can have a maximum character length of 128 characters, and tag values can have a maximum length of 256 characters.

Required: No

## Examples
<a name="API_UpdateRepositoryCreationTemplate_Examples"></a>

In the following example or examples, the Authorization header contents (`AUTHPARAMS`) must be replaced with an Amazon Signature Version 4 signature. For more information about creating these signatures, see [Signature Version 4 Signing Process](https://docs.amazonaws.cn/general/latest/gr/signature-version-4.html) in the * Amazon General Reference*.

You only need to learn how to sign HTTP requests if you intend to manually create them. When you use the [Amazon Command Line Interface (Amazon CLI)](http://www.amazonaws.cn/cli/) or one of the [Amazon SDKs](http://www.amazonaws.cn/tools/) to make requests to Amazon, these tools automatically sign the requests for you with the access key that you specify when you configure the tools. When you use these tools, you don't need to learn how to sign requests yourself.
