GetAuthorizationToken - Amazon Elastic Container Registry
Services or capabilities described in Amazon Web Services documentation might vary by Region. To see the differences applicable to the China Regions, see Getting Started with Amazon Web Services in China (PDF).

GetAuthorizationToken

Retrieves an authorization token. An authorization token represents your IAM authentication credentials and can be used to access any Amazon ECR registry that your IAM principal has access to. The authorization token is valid for 12 hours.

The authorizationToken returned is a base64 encoded string that can be decoded and used in a docker login command to authenticate to a registry. The Amazon CLI offers an get-login-password command that simplifies the login process. For more information, see Registry authentication in the Amazon Elastic Container Registry User Guide.

Examples

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 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) or one of the Amazon SDKs 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.

Example

This example gets an authorization token for your default registry.
