What is the FROM instruction good for in Docker?

Experience Level: Senior
Tags: Docker

Answer

The FROM instruction initializes a new build stage and sets the Base Image for subsequent instructions. As such, a valid Dockerfile must start with a FROM instruction. The image can be any valid image – it is especially easy to start by pulling an image from the Public Repositories.

Example:
FROM busybox
