Actions Defined by Amazon EC2 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.

Resources Defined by EC2 Container Registry

The following resource types are defined by this service and can be used in the Resource element of IAM permission policy statements.

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.
