Is it possible to use a private AWS ECR as a container registry as opposed to Docker Hub? Although RunPod allows username and password credentials to be configured (which would work with Docker Hub) there does not appear to be a feature to use AWS IAM credentials. The AWS CLI allows an IAM principal to obtain a password using
aws ecr get-login-password
aws ecr get-login-password
however this is only valid for 12 hours so would need to be cycled regularly but there does not appear to be a programatic way of doing this in RunPod.
I know this question isn't Serverless specific but I couldn't find a better place to put this question and we're using RunPod Serverless. I also think it might apply to Serverless more so than Pods due to the potential nature of having to pull images more frequently (potentially every cold start?).
