Since the
`docker:dind`
container and the runner container don't share their
root filesystem, the job's working directory can be used as a mount point for
children containers. For example, if you have files you want to share with a
child container, you may create a subdirectory under
`/builds/$CI_PROJECT_PATH`
and use it as your mount point (for a more thorough explanation, check
[
issue
#41227
](
https://gitlab.com/gitlab-org/gitlab-ce/issues/41227
)
):
```yaml
variables:
MOUNT_POINT: /builds/$CI_PROJECT_PATH/mnt
script:
- mkdir -p "$MOUNT_POINT"
- docker run -v "$MOUNT_POINT:/mnt" my-docker-image
```
