Let’s dive in and take a look at how our skilled Support Engineers recommend running a Docker image via the docker pull command.

Dealing with pulling image configuration AWS ECR error 

Did you know that it is possible to run a Docker image available in ECR by pulling it to the local environment via the docker pull command?

Well, our Support Engineers are here to show you how to get this done through a registry associated with another AWS account or through the default registry

Although, remember to keep in mind that users need to have permission to make calls to ecr:GetAuthorizationToken API via an IAM policy before authenticating to a registry and pull or push any image from any ECR repository.

Furthermore, ECR offers multiple IAM policies to control user access at different levels.

How to resolve pulling image configuration AWS ECR error

1. First, we will authenticate the Docker client to the ECR repository from where we plan to pull the image from.

   According to our Support Techs, it is essential to note that the authentications tokens are valid for 12 hours and have to be obtained for each registry used.
2. Although this step is optional, you can still go ahead and identify the image to be pulled:
   • First, list the repositories in the registry as seen below:

     aws ecr describe-repositories

   • Then, describe the images within the repository with the following command:

     aws ecr describe-images --repository-name amazonlinux

3. After that, we will pull the image via the docker pull command. Remember to keep the image name format as registry/repository[@digest] to pull by digest or registry/repository[:tag] to pull by tag.

   docker pull aws_account_id.dkr.ecr.us-west-2.amazonaws.com/amazonlinux:latest

In case you wind up with the “repository-url not found: does not exist or no pull access” error, worry not. We just have to authenticate the Docker client with Amazon ECR.
