ResourceInitializationError: unable to pull secrets or registry auth: pull command failed: : signal: killed

Question

I have created an Image in ECR, also created Fargate cluster and when I am defining task using hypens (-) for pulling ECR image e.g. 0000-0000-00000..dkr.ecr.ap-south-1.amazonaws.com/liferay:latest, I am getting 
ResourceInitializationError: unable to pull secrets or registry auth: pull command failed: : signal: killed.
2nd scenario while I am defining Task for pulling ECR Image 
without hypen (-)  0000000000000..dkr.ecr.apsouth1.amazonaws.com/liferay:latest, 
I am getting below error
CannotPullContainerError: inspect image has been retried 5 time(s): failed to resolve ref "000000000000.dkr.ecr.ap.south.1.amazonaws.com/liferay:latest": failed to do request: Head https://000000000000.dkr.ecr.ap.south.1.amazonaws.com/v2/liferay/manife...

Is Fargate not accepting hypens in Image name ?? or how to resolve, since Account Number and Regions contains hypen(s)

Accepted Answer

The correct domain for ECR is https://aws_account_id.dkr.ecr.region.amazonaws.com where the aws_account_id doesn't contain hyphens, and the region does.
So for example, if you account ID is 123456789012 and the region is ap-south-1, the domain would be https://123456789012.dkr.ecr.ap-south-1.amazonaws.com

If you go to the ECR repo in the AWS console you should see the actual URL to pull images
