AccessDeniedException when uploading your image to Amazon Elastic Container Registry (Amazon ECR)

If you get an AccessDeniedException error when you try to upload your container image to Amazon ECR, your IAM identity (user or role) might not have the necessary permissions to use Amazon ECR. You can attach the AmazonEC2ContainerRegistryPowerUser AWS managed policy to your IAM identity and try again. For more information about how to attach a policy, see Adding and removing IAM identity permissions in the AWS Identity and Access Management User Guide.
