Just a quick blog, probably more to help me remember in the future if I have a ‘Goldfish’ moment.

This blog post quickly outlines getting a salt minion running in a Docker container. Why? There are many reasons, but i’m doing some scaeability testing and Docker containers provide me with the ‘volume’ of minions I need to test out some topologies and scenarios. Don’t worry, i’ll blog the results.
I need a mixture of platforms so i’ve decided to create a Centos6 and Centos7 Docker container, just to see what Salt thinks about all this.

I’ve quoted that in its entirety because it’s important to keep the definitions in your mind as i’m going to refer to them several times during this post. Especially take note of the last sentence “…. cpusets allow you to associate a set of CPUs and a set of memory nodes with the tasks in each cgroup.” CGroups need to be combined with cpusets and other subsystems (controllers) to restrict compute resources. Make sure you check out the other CGroup controller documentation at  .
