You’re probably talking about Docker Desktop. It may not be on Linux (or at least your distro or whatever) because it’s not actually FLOSS. If you want to use Docker with a GUI I’ve had success with Rancher Desktop which is made by SUSE and is FLOSS. It’s still Docker (unlike podman which is not technically Docker), but it has a GUI for some stuff too.

I tried installing Docker Desktop at work and realized the license doesn’t actually allow that without paying. It was weirdly difficult to install Docker by itself on Mac so that led me to finding Rancher Desktop.
