How to Build Multi-Architecture Docker Images with BuildX | Deploy containers to x86 and ARM!

As ARM-based processors become more common, it is increasingly important to be able to build multi-architecture docker images to support x86 and ARM development systems and deployment targets.

In this video, I walk through how docker supports multi-architecture images and demonstrate how to use the buidx command to build a sample application and deploy onto x86 and ARM AWS servers.
