  Go language-specific guide
  This guide will show you how to create, test, and deploy containerized Go applications using Docker.
  Acknowledgment
  Docker would like to thank
  Oliver Frolovs
  for his contribution to this guide.
  What will you learn?
  In this guide, youâll learn how to:
  Create a
  Dockerfile
  which contains the instructions for building a container image for a program written in Go.
  Run the image as a container in your local Docker instance and manage the container's lifecycle.
  Use multi-stage builds for building small images efficiently while keeping your Dockerfiles easy to read and maintain.
  Use Docker Compose to orchestrate running of multiple related containers together in a development environment.
  Configure a CI/CD pipeline for your application using
  GitHub Actions
  Deploy your containerized Go application.
  Prerequisites
  Some basic understanding of Go and its toolchain is assumed. This isn't a Go tutorial. If you are new to the : languages:,
  Go website
  is a great place to explore,
  (pun intended) check it out!
  You also must know some basic
  Docker concepts
  as well as to
  be at least vaguely familiar with the
  Dockerfile format
  Your Docker set-up must have BuildKit enabled. BuildKit is enabled by default for all users on
  Docker Desktop
  If you have installed Docker Desktop, you donât have to manually enable BuildKit. If you are running Docker on Linux,
  please check out BuildKit
  getting started
  page.
  Some familiarity with the command line is also expected.
