does anyone have any tips for getting Docker BuildKit working? I have set the following set in

pants.toml

but my

pants package

still complains about buildkit-dependent features (

COPY --chmod

), and I notice that the relevant environment variable is not present in

__run.sh

in the sandbox when I run with

--keep-sandboxes=on_failure

. I've tried this on

2.16.0rc0

,

2.16.0rc5

, and

2.17.0rc0

.

[docker]
env_vars = [
    "DOCKER_BUILDKIT=1",
]

NB if I edit

__run.sh

to add

export DOCKER_BUILDKIT=1

to it, it happily runs the Docker build to completion.

I think this is a known issue. If you search here, you will find similar issues https://pantsbuild.slack.com/archives/C046T6T9U/p1683579800781919
