+
+# Data Source: aws_ecr_authorization_token
+
+The ECR Authorization Token data source allows the authorization token, proxy endpoint, token expiration date, user name and password to be retrieved for an ECR repository.
+
+## Example Usage
+
+```hcl
+data "aws_ecr_authorization_token" "token" {
+}
+```
+
+## Argument Reference
+
+The following arguments are supported:
+
+* `registry_id` - (Optional) AWS account ID of the ECR Repository. If not specified the default account is assumed.
+
+## Attributes Reference
+
+In addition to the argument above, the following attributes are exported:
+
+* `authorization_token` - Temporary IAM authentication credentials to access the ECR repository encoded in base64 in the form of `user_name:password`. 
+* `proxy_endpoint` - The registry URL to use in the docker login command.
+* `expires_at` - The time in UTC RFC3339 format when the authorization token expires.
+* `user_name` - User name decoded from the authorization token.
+* `password` - Password decoded from the authorization token.
