Docker Kata 6: Creating Docker Images

The previous katas have used images provided on Docker Hub. Most of those images are created and managed by software vendors.

This kata will demonstrate how we can define and build our own images for our own use or to distribute to others. This kata will cover two ways to create an image:

• Commit changes to a modified container.
• Build an image from a Dockerfile.
