Introduction to Security in Docker
Explore how Docker integrates multiple security layers such as namespaces, control groups, and Mandatory Access Control to protect containers. Understand Docker's own security tools like Docker Scout for vulnerability scanning and Docker Content Trust for image signing. Discover how Docker Swarm enhances security through encrypted communications and automatic certificate management, enabling you to implement robust container security effectively.
We'll cover the following...
If security is hard, we’re less likely to implement it. Fortunately, most of the security in Docker is easy and preconfigured with sensible defaults. This means you get a moderately secure experience with zero effort. The defaults are not perfect, but they’re a good starting point.
Docker supports all major Linux security technologies and adds some of its own. As such, we’ve divided the chapter to first cover ...
