Summary
In this chapter, we looked at the basics of using cgroups Version 1 to control resources. A lot of information you've likely seen in your web searches is out of date and somewhat confusing. My goal for this chapter has been to bring you up-to-date information and present it in an understandable manner.
We started by looking at the cgroups Version 1 controllers and giving a brief explanation of each one. After that, we saw how to control CPU usage, memory usage, and block device bandwidth usage for both users and services. We wrapped up by showing you the old, non-cgroup way of setting limits, which is still useful.
In the next chapter, we'll look at cgroups Version 2. I'll see you there.
