Introduction to Security in Docker

Good security is all about layers, and Docker has lots of layers. It supports all the major Linux security technologies and also has plenty of its own. And the best thing, many of them are simple and easy to configure.

In this chapter, we’ll look at some of the technologies that can make running containers on Docker very secure.

When we get to the deep dive part of the chapter, we’ll divide things into two categories:

• Linux security technologies
• Docker security technologies

Large parts of the chapter will be specific to Linux. However, the Docker security technologies section is platform agnostic and applies equally to Linux and Windows.
