s3-us-east-1.amazonaws.com’s server IP address could not be found.

While building the docker image, it needs to configure a emr yum repo and install packages from this yum repo.

When I set REGION to be ue-east-1, docker build cannot resolve the yum repo.

Then I found this is caused by the following line.

sagemaker-spark-container/spark/processing/3.1/py3/yum/emr-apps.repo

Line 3 in 3ccb729

gpgkey = https://s3-REGION.amazonaws.com/repo.REGION.emr.amazonaws.com/apps-repository/emr-6.3.0/184d7755-d3a2-4c5c-9e1f-c72d4f2b33f1/repoPublicKey.txt

Specifically, when REGION=us-east-1, this url cannot be resolved. This is confirmed when I tried to visit this url in my browser, I got "s3-us-east-1.amazonaws.com’s server IP address could not be found."

From the s3 endpoint document, it seems that the format of the url should be https://s3.REGION.amazonaws.com/ .... Is my understanding right?
