cannot bind files in the /usr/local/bin

• I have tried with the latest version of my channel (Stable or Edge)
• I have uploaded Diagnostics
• Diagnostics ID: 480A9FC0-73DA-48AD-9FFF-61D286A068E1/20190315014239

Expected behavior

Docker command successfully binds files in the /usr/local/bin in the same way Docker on Linux.

$ docker run --rm -v /usr/local/bin/docker-slim-sensor:/tmp/docker-slim-sensor:ro nginx ls /tmp
docker-slim-sensor

Actual behavior

When a docker command mounts with -v option, it shows the File Sharing error.

$ docker run --rm \
          -v /usr/local/bin/docker-slim-sensor:/tmp/docker-slim-sensor:ro \
           nginx /tmp/docker-slim-sensor
docker: Error response from daemon: Mounts denied:
The path /usr/local/bin/docker-slim-sensor
is not shared from OS X and is not known to Docker.
You can configure shared paths from Docker -> Preferences... -> File Sharing.
See https://docs.docker.com/docker-for-mac/osxfs/#namespaces for more info.
.
ERRO[0000] error waiting for container: context canceled

However, when it mounts with --mount option, it shows no such file or directory.

docker run --rm \
      -it \
      --mount type=bind,source=/usr/local/bin/docker-slim-sensor,target=/tmp/docker-slim-sensor,readonly \
      nginx /tmp/docker-slim-sensor
docker: Error response from daemon: invalid mount config for type "bind": bind source path does not exist: /usr/local/bin/docker-slim-sensor.
See 'docker run --help'.

In fact, the target directory which is bound /usr/local/bin did not any binaries in the source path(it does not occured outside of /usr/local/bin, and no problem on Linux).

$ ls /usr/local/bin/docker-slim-sensor
-rwxr-xr-x 1 aigarash 4362570 Feb  4 01:05 /usr/local/bin/docker-slim-sensor

$ docker run --mount type=bind,source=/usr/local/bin/,destination=/tmp,readonly nginx ls /

Steps to reproduce the behavior

1. To put docker-slim-sensor to /usr/local/bin
2. To run the following command

docker run --rm \
      -it \
      --name devtest2 \
      --mount type=bind,source=/usr/local/bin,target=/tmp/,readonly \
      nginx:latest /tmp/docker-slim-sensor

Docker Desktop on Mac has a whitelist of host directories which may be shared with containers. Since /usr/local/bin is not in your whitelist Docker prints the error

The path /usr/local/bin/docker-slim-sensor is not shared from OS X and is not known to Docker.

If you click on the whale menu -> Preferences you should be able to add /usr/local/bin to the whitelist and hopefully the docker run -v will work as expected. See the section on "File Sharing" in the docs.

Let me know if that makes it work as expected or if you're still having problems.

I set /usr/local/bin to the file sharing path but it's still having problems.

$ docker run --mount type=bind,source=/usr/local/bin/,destination=/tmp,readonly nginx ls /tmp
containerd
containerd-shim
ctr
docker
docker-init
docker-proxy
dockerd
runc
