🔥🔥🔥Containers from Scratch🔥🔥🔥
This is write up for talk I gave at CAT BarCamp, an awesome unconference at Portland State University. The talk started with the self-imposed challenge “give an intro to containers without Docker or rkt.”
Often thought of as cheap VMs, containers are just isolated groups of processes running on a single host. That isolation leverages several underlying technologies built into the Linux kernel: namespaces, cgroups, chroots and lots of terms you’ve probably heard before.
So, let’s have a little fun and use those underlying technologies to build our own containers.
