We use it, and I honestly don’t see much value. I use 90% CLI, but occasionally it’s nice. I use macOS at work, so it’s nice to be able to see how much space the VM is using. Also, searching through logs is a little nicer through the GUI than the CLI.
I actively avoid the GUI at home because, even on Linux, it’ll spin up a VM to host your containers, whereas if you stick with the CLI, there’s no VM, which solves soooo many headaches.
I think docker desktop’s bigger value prop is that it’s a well supported zero-effort setup of a VM to run the docker daemon on platforms that don’t support it natively (i.e. MacOS which a lot of programmers use). And it very cleanly handles mounting your local filesystem into containers running in the VM, which is important for dev envs and used to be a source of friction with alternatives (although it seems like the competition has caught up and this also now works out of the box with rancher desktop and others?). Having a GUI is somewhere behind those, though I know folks who have a weird preference for GUIs 🤷♀️.
I’m just a guy who uses Linux and spends most of his time in a terminal, so I’m not saying I value docker desktop, and I personally don’t have to deal with any of this so I’m probably behind on how good the alternatives are. Just saying where I see other people get use out of it.
