In this course you will learn why Go is an awesome language for writing command-line programs. You will learn how to structure your Go programs, how to write idiomatic Go code, how to test your programs and how to amaze your users, peers and managers. 

The focus is on command-line programs in order to keep the course down to earth, but most of the principles and best practices you will learn apply to any Go program.

## Using a multi-stage Dockerfile

One of the main benefits of Docker is that it can potentially create very small images, which require less resources and are more secure due to the small surface area. In the previous section, you saw that we can build a 10MB multi-git executable. However, building it requires a lot of foundation. Here is a simple Dockerfile based on the golang:1.14 base image that builds multi-git. I saved it as `Dockerfile.big`:
