As previously announced, we've taken the same philosophies that made buildpacks so successful and applied them towards creating Cloud Native Buildpacks (CNB), a standard for turning source code into Docker images without the need for Dockerfiles. In this post, we'll take a look at how CNBs work, how they aim to solve many of the problems with that exist with Dockerfile, and how you can use them with...
