Docker build fails to mount a single file

[RocketJas]

There is an issue with the version of docker on the latest AzureLinux container image

Docker build failing to mount single file via bind When running docker build (with DOCKER_BUILDKIT=1) on the mariner image, the RUN stage fails when attempting to mount a single file --mount=type=bind with the error

executor failed running [/bin/bash -euxc bash tmp/test_mount.sh]: failed to mount /var/lib/docker/tmp/buildkit-mount3000888503: [{Type:bind Source:/proc/self/fd/25 Options:[rbind ro]}]: not a directory

To Reproduce Steps to reproduce the behavior:

1. Ensure you are running on a mariner OS
2. Clone repo
3. Set the Environment Variable export DOCKER_BUILDKIT=1
4. From the root directory run docker build -t test_dockerfile_mariner -f test.dockerfile .
