January Virtual Meetup Recap: Improve Image Builds Using the Features in BuildKit

This is a guest post by Docker Captain Nicholas Dille, a blogger, speaker and author with 15 years of experience in virtualization and automation. He works as a DevOps Engineer at Haufe Group, a digital media company located in Freiburg, Germany. He is also a Microsoft Most Valuable Professional.
