Every time I see Apple flaunting Linux containers I can hardly consider it as anything but admitting defeat. It could easily be Darwin, if they still had the capacity.

Apple set itself up for defeat in the server and developer marketplace as soon as they decided macOS was proprietary code. Why would any serious developer use closed-source code they can't debug and modify? Especially for a production server? It's the same reason no serious developers or hackers use macOS, like part of the point of being a developer is being able to dig into the code at any layer and debug and fix th…

I know I'm basically taking the bait, but I guess I've not been "seriously" developing stuff for the past decade or two, which is news to me!

I belong to a rare breed of very opportunistic hobby-developers that like to use MacOS but also like to use linux machines or BSDs (rpi etc) sometimes.

I can create docker-images with docker compose, or use something like colima, which this seems to be close to (that should have some advantages over docker, although my hope of circumventing W^X page protection did not pan out).

I was perplexed that the repository does not put these container machines in context. The seem to be close to colima? When should I use which option (docker, collima, container machines ?)

Maybe others wonder too but are ashamed to ask. I have no shame ;)

Thanks for any pointers

It was unclear to me, is this a native replacement for docker? I like docker (on mac) but its quite the resource hog.

I usually run like a db, redis, maybe something like rabbitmq/zeromq and have a app that uses these services (makefile/docker-compose).

I would love to switch if this in fact is a lightweight replacement.

Earlier quoted context omitted.

I mean at this point literally anything works better than Windows.

Except game development, hence Proton.

it always gets a sad chuckle out of me to hear that some native linux ports run worse than the windows version under proton. i think valve games are like that (l4d2 for example) and recently I think Hollow Knight: Silksong was like that

With colima I can run AMD64 (x86) Linux containers in my Arm64 too. I think this is strictly for Arm64 Linux VMs, or is there some way to run x86 with this too?

What’s the performance when you do that?

To clarify a few comments here: this is not only OCI containers: container machines add support for persistence and filesystem mounting, making container machines a great lightweight Linux environment for developers using macOS.

The katas container kernel by default.
