Running cog build with the following docker config in a Ubuntu virtual machine:

Produces the following:

Building Docker image from environment in cog.yaml as cog-xxx...
⚠ Stripping patch version from Python version 3.11.9 to 3.11
⚠ Stripping patch version from Python version 3.11.9 to 3.11
unknown flag: --cache-to
See 'docker --help'.

Ideally this should be worked around to check if docker supports the --cache-to flag.

same error. any recommendations?

UPD: The problem was that the docker-buildx-plugin was not installed. It is installed, for example, as described here, in the answers . After that everything works.
