Dockerfile COPY and ADD with buildkit fails with: cross-device link

[awdAvenger]

COPY and ADD fails when trying to use ADD or COPY in a simple Dockerfile like this:

FROM ghcr.io/macoscontainers/macos-jail/ventura:latest

COPY testfile /testfile

The failure is:

Dockerfile:3
--------------------
   3 | >>> COPY testfile /tmp/testfile
   4 |     
   5 |     
--------------------
ERROR: failed to solve: failed to copy files: cross-device link

Workaround for now is to use DOCKER_BUILDKIT=0 when using ADD or COPY.

This was already fixed in dockerd 0.0.4. Please, brew update && brew upgrade && sudo brew services restart dockerd to get the fix.

I still get this with dockerd 0.0.4. I even tried a reboot to make sure all the latest versions were running.

Here are my currently installed versions:

Hmm... Let me recheck.

You're right, I've messed things up a bit. Should be fixed in dockerd 0.0.5
