Will this Linux kernel facility limit a Docker container's access to host resources, such as CPU or memory? Solution: cgroups

Docker uses cgroups, a Linux kernel feature, to limit the resources a container can use.This includes

CPU and memory resources12.For instance, Docker can limit a container’s CPU usage to the

equivalent of a single CPU core on the Docker host system2.Similarly, Docker can limit a container’s

memory usage1.However, to use these features, the Docker host must have cgroup memory and

swap accounting enabled1.Therefore, cgroups can indeed limit a Docker container’s access to host

resources such as CPU and memory12.
