Unix sockets are limited to 108 bytes. As a result, we need to be careful in not using exec-root as the parent directory for pluginID (which is already 64 bytes), since it can result in socket path names longer than 108 bytes. Use /tmp instead. Before this change, setting: - dockerd --exec-root=/go/src/github.com/do passes - dockerd --exec-root=/go/src/github.com/doc fails After this change, there's no failure. Also, write a volume plugins test to verify that the plugins socket responds.
