Resolution

Since RHEL7 is in the Maintenance Support 2 phase, Red Hat has decided not to fix this bug.

Workaround

Downgrade docker-distribution package to docker-distribution-2.4.1-2.el7.x86_64

With docker-distribution-2.4.1-2.el7.x86_64, only following regions are supported

                "us-east-1",
                "us-west-1",
                "us-west-2",
                "eu-west-1",
