PutImage - Amazon Elastic Container Registry


Creates or updates the image manifest and tags associated with an image.

When an image is pushed and all new image layers have been uploaded, the PutImage API is called once to create or update the image manifest and the tags associated with the image.


This operation is used by the Amazon ECR proxy and is not generally used by customers for pulling and pushing images. In most cases, you should use the docker CLI to pull, tag, and push images.

HTTP Status Code: 400


The specified parameter is invalid. Review the available parameters for the API request.

HTTP Status Code: 400

HTTP Status Code: 400


The specified layers could not be found, or the specified layer is not valid for this repository.

HTTP Status Code: 400

In the following example or examples, the Authorization header contents (AUTHPARAMS) must be replaced with an AWS Signature Version 4 signature. For more information about creating these signatures, see Signature Version 4 Signing Process in the AWS General Reference.

You only need to learn how to sign HTTP requests if you intend to manually create them. When you use the AWS Command Line Interface (AWS CLI) or one of the AWS SDKs to make requests to AWS, 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.


This example puts an image to the amazonlinux repository with the tag 2016.09.
