Run Docker plugins.
Can’t run docker plugins.
- the output of:

- a reproducible case if this is a bug, Dockerfiles FTW
Here is the repo for the plugin I’m trying to use: https://github.com/CWSpear/local-persist (I am the author)
- page URL if this is a docs issue or the name of a man page
The popup mentions looking to the docs for more about reserved paths. I couldn’t find anything in the docs.
- host distribution and version ( OSX 10.10.x, OSX 10.11.x, Windows, etc )
OS X 10.11.6
Steps to reproduce the behavior
docker run -d \ -v /run/docker/plugins/:/run/docker/plugins/ \ -v /data/plugin-data/:/var/lib/docker/plugin-data/ \ -v /data/:/data/ \ --name local-persist \ cwspear/docker-local-persist-volume-plugin
This command works on a “regular” Docker host (tested with Docker 1.12 on Ubuntu 16.04). On Docker for Mac, you get this error:
docker: Error response from daemon: Mounts denied: The path /run/docker/plugins/ 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.
If I try to add
/run to my shared path in the Docker for Mac preferences, I get this error:
In general, how does one run plugins on Docker for Mac? It would be preferable to run then directly on the host. (Docker recommends running plugins outside of containers. See last paragraph under What plugins are from the Plugins API docs.) As it stands, I can’t do either.
