My org's management wasn't taking the issue seriously, but once the subscription cost reached one FTE's salary, they started listening to people who had already switched to Podman, Rancher or (Co)Lima.
I'll not deny that it's a bit niche, but not so much so that it's completely unknown.
"Apple developer circles" to me means the few mostly indies who build non-electron Mac apps and non-ReactNative ios apps, but those developers mostly are writing client code and don't even touch servers.
All this said, my above "gut feelings" don't explain why Apple would have bothered spending their time making this when Orbstack, Docker, etc. already meet the needs of the developers on Mac who actually need and use containers.
[0]: besides the "Command line tools" that allow compilation to work, of course.
Before Orbstack, running Docker on Macs was a total pain - the official desktop app is so awful, I doubt anyone at Docker is actually using it. Nevertheless, it was still too useful to let it pass. It was time either Docker or Apple stepped up, but they are both 10 years late to this party. Orbstack fixed the problem.
It would be interesting to see the reaction from Danny Lee, he's hanging out on HN sometimes. I hope this framework ends up being a building block, rather than outright competition.
I'm sure Apple will try to push their own version of Docker but I'm not sure if they'll be able to win over any Docker Desktop businesses unless their tool also works on other operating systems.
Sadly all of them are Electron based.
WSL2 provides everything you need to install the docker daemon and CLI, and the VS Code extension gives you a pretty decent GUI, there's no need for anything else really.
