It’s not virtualization, it’s namespaces. Docker makes use of Linux kernel features; started out with cgroups and now uses libcontainer. Each container is running in its own isolated(ish) namespace on the same host kernel. It’s _very_ different technology than virtualization. You don’t need docker to make a container on Linux (or Solaris for that matter). |

You are incorrect, this is OS-level virtualization:
"OS-level virtualization is an operating system (OS) virtualization paradigm in which the kernel allows the existence of multiple isolated user space instances, including containers (LXC, Solaris Containers, AIX WPARs, HP-UX SRP Containers, Docker, Podman)..."[0].

Yes, OS-level virtualization.

Incorrect, this is a virtualization technology.

No one claimed otherwise.
