Is the folder name provided in the shared folder settings of the sudo mount -t vboxsf -o defaults,uid=1000,gid=50 docker-shared docker-sharedД©. Syntax : sudo mount -t vboxsf -o defaults,uid= ,gid= Is the name of the directory created on the 'default' VM. Execute the following command to mount the host directory previously shared to the VM Create a directory named вЂdocker-sharedвЂ™ on the Linux VM mkdir docker-sharedДЁ. Execute the following command and note down the GID and UID values. $ VBoxManage start default Ensure the terminal connects to the docker boot2dock virtual machine $ eval '$(docker-machine env default)'Д¦. Use the following command or start the 'default' VM via the VirtualBox application. $docker-machine ssh default Note : Make sure that the boot2docker is already running. This should log you into the вЂdefaultвЂ™ Linux VMвЂ™s shell. Log into the running вЂdefaultвЂ™ machine using the following command. Enable вЂAuto MountвЂ™ and вЂMake PermanentвЂ™. In this example, I have provided вЂњdocker-sharedвЂќ as the name for the folder.Д¤. Set вЂњFolder PathвЂќ to a directory on OSX that you would like to use as Volume. Open up the Virtualbox UI and find the вЂdefaultвЂ™ machine.ДЈ. This would be a straightforward task in Linux installations but in OSX, since Docker is running on a Linux VM, we would have to create a mount pipe between the HOST and container through the Linux VM.ДЎ. docker-volume:/mounted-volume -name=docker-volume-demo my-image The -v command param is asking docker to make the вЂdocker-sharedвЂ™ directory present in the current location and expose it as вЂmounted-volumeвЂ™ at root location of container VM.

Any information that the container writes to this mounted directory or in this case called VOLUME, persists independent of the container lifecycle.Д«elow is an example of how to mount volume while starting the container. Volumes are nothing but a directory present on the HOST machine which is mounted to the container. Data stored in volumes are persisted even after the container has exited. Volumes help bring in data persistence to containers. Once the container exist, the data written to the file system is removed. This read-write layer enables the process running in the container to read and write files during its run. Д¬ontainers are nothing but images with a read-write layer on top of it. Now when the вЂњdocker runвЂќ command is executed with the volume parameters, it is the вЂњdirectoryвЂќ on the guest OS (boot2docker вЂdefaultвЂ™ VM ) which gets mounted onto the container. This ensures access of the host(OSX) directory contents to the guest OS (boot2docker вЂdefaultвЂ™ VM).

вЂњdocker runвЂќ command run the docker image in a container on the вЂњdefaultвЂќ VM.ДЄ directory present on the OSX (host machine) is first mounted to a directory of the same name(need not be of the same name) on the VM.

Boot2Docker is launched in a virtual machine named вЂdefaultвЂ™ on VirtualBox.

If you execute the following command in the shell you will see that the IP address returned is different from the HOST machine. The docker daemon is running on the linux VM and you use the docker client to connect to it. Instead of running directly on the host, docker runs on a small light weight scaled down Linux virtual machine named вЂdefaultвЂ™.

On a Linux installation Docker runs directly on the host but on MAC OSX it runs in a slightly different manner.
