Hello, I am not sure this is good place to ask about macos & docker but: I have macos and I use Ranched Desktop, Currently when I run docker compose up, my volume files became to be directory in container or does not copy to container. Do I have to change any system settings?

Mounting a volume with docker run or compose into a container does not copy data, just lets you access a local folder as a folder inside the container. https://docs.docker.com/engine/reference/commandline/run/#mount-volume--v---read-only

test-mock:
  build: test-mock
  volumes:
    - ./files:/opt/wiremock/__files
  ports:
    - 8090:8080

# ls -l __files/

total 0

left is local, right is the path in the container so

docker run -v /tmp:/container_tmp busybox ls /container_tmp

Maps /tmp on the local machine to /container_tmp inside the container. This probably should be posted on StackOverflow, etc since it's not RD-specific

I'm on a Mac and mount volumes ok. Related to that ^^^ issue, I posted this earlier and didn't get any reply.

yeah this is similar I guess so.
