In this chapter, we looked at how to keep up with security-related issues that not only pertain to Docker products that you may be running now or in the near future, but they also pertain to security issues such as kernel issues. As Docker relies on the kernel for all Docker containers on a Docker host, the kernel is very important. We looked at multiple mailing lists that you can sign up for, getting notifications in this manner. Joining IRC chat rooms and following GitHub issues for anything security-related or anything that isn't currently working might affect your environments. It is very important to always keep security in the front of your mind when deploying anything and while the Docker is inherently secure, there are always people out there that will take advantage of any given vulnerability, therefore, keep all of your environments safe and as up to date as possible.
