Actions Defined by Amazon Elastic Container Registry

You can specify the following actions in the Action element of an IAM policy statement. By using policies, you define the permissions for anyone performing an operation in AWS. When you use an action in a policy, you usually allow or deny access to the API operation or CLI command with the same name. However, in some cases, a single action controls access to more than one operation. Alternatively, some operations require several different actions. For details about the columns in the following table, see The Actions Table.

Actions	Description	Access Level	Resource Types (*required)	Condition Keys	Dependent Actions
BatchCheckLayerAvailability	Check the availability of multiple image layers in a specified registry and repository.	Read	repository*

Resources Defined by Elastic Container Registry

The following resource types are defined by this service and can be used in the Resource element of IAM permission policy statements. Each action in the Actions table identifies the resource types that can be specified with that action. A resource type can also define which condition keys you can include in a policy. These keys are displayed in the last column of the table. For details about the columns in the following table, see The Resource Types Table.

Resource Types	ARN	Condition Keys
repository	arn:${Partition}:ecr:${Region}:${Account}:repository/${RepositoryName}	aws:ResourceTag/${TagKey} ecr:ResourceTag/${TagKey}

Condition Keys for Amazon Elastic Container Registry

Amazon Elastic Container Registry defines the following condition keys that can be used in the Condition element of an IAM policy. You can use these keys to further refine the conditions under which the policy statement applies. For details about the columns in the following table, see The Condition Keys Table.

To view the global condition keys that are available to all services, see Available Global Condition Keys in the IAM Policy Reference.

Condition Keys	Description	Type
aws:RequestTag/${TagKey}	Filters create requests based on the allowed set of values for each of the tags.	String
aws:ResourceTag/${TagKey}	Filters actions based on tag-value associated with the resource.	String
aws:TagKeys	Filters create requests based on the presence of mandatory tags in the request.	String
ecr:ResourceTag/${TagKey}	Filters actions based on tag-value associated with the resource.	String
