Dockerfile configuration often requires one-time setup of certain commands and options, making it difficult to remember exactly what those options are and how to use them. This quickly leads to copy-and-paste development of Dockerfile configuration, taking options from one Dockerfile and placing them into another without really understanding them.
There's a problem, though. Copy-and-paste is the root of many problems in software development. It's a design problem, and a configuration problem that can lead to bugs and errors being quickly duplicated.
With the Advanced Dockerfile Cheatsheet, you won't need to rely on copy-and-paste to get the one-time Dockerfile configuration options set up correctly. You'll have quick access to a description of many of Docker's advanced options, right at your fingertips.
