Agreed. The post feels a bit pedantic; I don't know any dev doing "cool things" with the underlying namespaces/cgroups. They're just using Docker. De-mystifying containers has value, but so does the abstraction.


The abstraction muddles the performance, security etc. impact of these two models. Not knowing them is going to be bad in the long run. Not everyone is a web dev.


Plenty of them using those features, if they’re using Kubernetes, Docker Swarm or especially Istio.

They might not know they are, but that’s besides the point.

I actually thought that was exactly the point here...


Your personal ignorance makes a poor argument.

Not only do I know several devs doing cool things with namespaces and cgroup, but I myself have done cool things with namespaces and cgroups.

I played with Docker briefly, but it has no real practical application in my line of work.


And I'm a dev "doing cool things" with namespaces / cgroups.
