Building docker images on EC2's A1 instances and running them on Xavier

It looks like AWS has new instance types that run on Arm’s Aarch64 chips. https://aws.amazon.com/blogs/aws/new-ec2-instances-a1-powered-by-arm-based-aws-graviton-processors/

Theoretically you should be able to build any docker image there, push it to dockerhub, and pull it on Xavier and it’ll work.

I am wondering if anyone has attempted something similar?

My reasoning is I need to build a rather very large and complex container (baidu’s apollo – self driving car platform). So building it on an EC2 instance makes a lot more sense than on the Xavier itself with limited CPU and RAM.
