To summarize, containers aren’t just slightly more isolated and restricted Linux processes. Instead, they are standardized execution environments improving workload portability. Linux containers are the most widespread form of containers nowadays, but the need for more secure containers is growing. The OCI Runtime Spec defines the VM-backed containers, and the Kata project makes them real. So, it’s an exciting time to explore the containerverse!
The difference between docker (or podman, or containerd) attach and exec commands is a common source of confusion. And it’s understandable - these two commands have similar arguments and, at first sight, similar behavior. However, attach and exec aren’t interchangeable. They aim to cover different use cases, and the implementation of the commands also differs. But still, it might be hard to remember when to use which command.

The management of fonts that are not packaged in Linux distributions can be performed with a handful of command line tasks. While this takes a bit more effort than font management with a GUI font manager or package manager application, the steps are simple, and an understanding of them will allow you to install and use the many unpackaged fonts that are available out there.
When you are new to Docker (or Podman, or nerdctl), the number of commands you need to learn can be truly overwhelming.
