The Container Coloring Book: Who's afraid of the big bad wolf?
The three little pigs teach you how to keep the big bad wolf from blowing your container-based applications down. In the process, they will cover namespaces, resource control, security, images, open standards, and management—all important characteristics to keep in mind as you build your container-based applications.
"Piggies living in an apartment building are like applications running in containers. You get excellent sharing of services, lower cost of maintenance and decent separation. One problem, though, is that if the front desk were compromised, then all of the apartments would be compromised.This is similar to a container environment where, if the kernel were compromised, all of the containers would be as well."
