Further reading

While this chapter provided an insight into the container ecosystem and the knowledge needed to pass the KCNA exam, it doesn’t cover all the features of Docker tooling nor describes cgroups and namespaces in detail. If you’d like to go the extra mile, you are encouraged to check out the following resources:

• cgroups v1: https://www.kernel.org/doc/Documentation/cgroup-v1/cgroups.txt
• Namespaces: https://man7.org/linux/man-pages/man7/namespaces.7.html
