This doesn't really clear up any of the questions I have. Will docker running on ARM run docker containers from images built for x86? Will docker running on ARM be able to build images for x86?

Answer your own question: Can Docker on ARM run x86? Can Docker on x86 run ARM?

If not, then why expect Apple ARM to run x86?

Right. if it is building it's own linux kernel and build container it defeats the purpose of having a docker....

Running docker containers on Darwin already required you to run a Linux kernel, though?

The question is: why even care?

Use an Arm image. For docker, it makes little to no difference

If Docker can run on Raspberry Pi's ARM chips, it can run on Mac ARM chips. I expect we'll see this working very soon after the new Macs start to arrive.

Docker is architecture specific though. The meaningful question is whether it can run the same docker images as it did on the previous Mac hardware or not.

Yes but this was possible through virtual machine(virtualbox)

Through QEMU

isnt that linux specific?

Sounds a bit like Docker is at a loss. Caught between a closed source OS (rock) and an architecture change (hard place).

Ideally, they could leverage Rosetta2 to run x64 containers under macOS on Apple Silicon ... but I guess Apple isn't playing ball (because otherwise they would have probably announced it at WWDC).

At this point I see an Apple Silicon based Mac is just a consumer device, I don't think I'm going to be able to use it in anger for development work at the moment (other than for Mac consumer apps).

Not really sure what Apple have to lose here ... but if Macs with Apple Silicon are not a viable dev platform for "mainstream" containers, then that's going to drive developers to Linux (or Windows).

that mean you need to have an arm based server for deployment of your code / services.

Apple ARM can run x86 under Rosetta 2. The question is whether that can happen under Docker.

That requires that ARM images are available, which will take time and always have a disconnect. It also violates the idea of being able to run the exact same image on your laptop (ARM Mac) and in prod (x86 server).
