Who is the Docker Basics poster for?

Docker Basics belongs to the Computing section rather than to a school year, because computing is not something one grade owns. Anyone learning tools can pin it up — a beginner, a student mid-course, or someone revising years later.

When should you use the Docker Basics poster?

Image, container, volume. Almost every Docker question is a confusion between the first two. A wall chart earns its place by being glanceable from where the work is happening, so Docker Basics belongs on the wall where that computing work actually happens, within glancing distance, rather than filed away.
