Authentication (or accessing private repositories)

[BigTexasDork]

I'm trying to find any information on credentials, specifically around pulling from AWS ECR, but information about other private repositories would be helpful. In my case, I've got my AWS credentials configured so that a docker pull works, but a container image pull doesn't. Where can I find information about if/when container will support private repositories? I searched the discussions for "Authentication", "Credentials", "ECR" and nothing returns.

TIA

I knew as soon as I created a discussion, I'd find the answer:
ws ecr get-login-password --region us-west-2 | container registry login --username AWS --password-stdin <ecr_domain>
