How to use it

Configuration

$REPO_ROOT/docker-volume.yml

volumes:
  mysql:
    hostpath: ${here}/../volumes/mysql/
    vboxpath: /var/lib/mysql
    uid: 0
    gid: 0
    dmode: 777
  mongo:
    hostpath: ${here}/../volumes/mongo/
    vboxpath: /var/lib/mongo
    uid: 0
    gid: 0
    dmode: 777
  redis:
    hostpath: ${here}/../volumes/redis/
    vboxpath: /var/lib/redis
    uid: 0
    gid: 0
    dmode: 777

Add volume

$ docker-volume add
EXECUTE: VBoxManage sharedfolder add default --name docker-example_redis --hostpath /path/to/hostdir/volumes/redis
EXECUTE: VBoxManage sharedfolder add default --name docker-example_mysql --hostpath /path/to/hostdir/volumes/mysql
EXECUTE: VBoxManage sharedfolder add default --name docker-example_mongo --hostpath /path/to/hostdir/volumes/mongo

Mount volume

Start docker machine.

$ docker-machine start default
(dev) Starting VM...
Machine "default" was started.
Started machines may have new IP addresses. You may need to re-run the `docker-machine env` command.

mount volume.

$ docker-volume mount
EXECUTE: docker-machine ssh default "sudo mkdir -p /var/lib/mysql &&  sudo mount -t vboxsf -o uid=0,gid=0,dmode=777 docker-example_mysql /var/lib/mysql"
EXECUTE: docker-machine ssh default "sudo mkdir -p /var/lib/mongo &&  sudo mount -t vboxsf -o uid=0,gid=0,dmode=777 docker-example_mongo /var/lib/mongo"
EXECUTE: docker-machine ssh default "sudo mkdir -p /var/lib/redis &&  sudo mount -t vboxsf -o uid=0,gid=0,dmode=777 docker-example_redis /var/lib/redis"

Make sure that it is mounted.

$ docker-machine ssh default "mount | grep /var/lib"
/dev/sda1 on /mnt/sda1/var/lib/docker/aufs type ext4 (rw,relatime,data=ordered)
none on /var/lib/mongo type vboxsf (rw,nodev,relatime)
none on /var/lib/redis type vboxsf (rw,nodev,relatime)
none on /var/lib/mysql type vboxsf (rw,nodev,relatime)

Unmount volume

Unmount volume.

$ docker-volume unmount
EXECUTE: docker-machine ssh default "sudo umount /var/lib/redis"
EXECUTE: docker-machine ssh default "sudo umount /var/lib/mysql"
EXECUTE: docker-machine ssh default "sudo umount /var/lib/mongo"

Make sure that it is unmounted.

$ docker-machine ssh default "mount | grep /var/lib"
/dev/sda1 on /mnt/sda1/var/lib/docker/aufs type ext4 (rw,relatime,data=ordered)

Remove volume

Stop docker machine.

$ docker-machine stop
(dev) Stopping VM...
Machine "default" was stopped.

Remove volume.

$ docker-volume remove
EXECUTE: VBoxManage sharedfolder remove default --name docker-example_mongo
EXECUTE: VBoxManage sharedfolder remove default --name docker-example_mysql
EXECUTE: VBoxManage sharedfolder remove default --name docker-example_redis

Volume name

Volume name is ${REPOSITORY_DIRECTORY_NAME}_${VOLUME_NAME}.

Other

If you want to specify the machine name it?

It specifies the -m or –machine option.

$ docker-volume add --dry-run --machine example
EXECUTE: VBoxManage sharedfolder add example --transient --name docker-volume_repo --hostpath /path/to/hostdir/volumes/docker-volume
EXECUTE: VBoxManage sharedfolder add example --transient --name docker-volume_spam --hostpath /path/to/hostdir/volumes/spam
EXECUTE: VBoxManage sharedfolder add example --transient --name docker-volume_ham --hostpath /path/to/hostdir/volumes/ham

If you want to specify the single volume?

It will specify a volume name if you want to operate a volume.

$ docker-volume add --dry-run spam
EXECUTE: VBoxManage sharedfolder add default --transient --name docker-volume_spam --hostpath /path/to/hostdir/volumes/spam

and it will specify two volume name if you want to operate two volumes.

$ docker-volume add --dry-run spam ham
EXECUTE: VBoxManage sharedfolder add default --transient --name docker-volume_spam --hostpath /path/to/hostdir/volumes/spam
EXECUTE: VBoxManage sharedfolder add default --transient --name docker-volume_ham --hostpath /path/to/hostdir/volumes/ham

If you do not specify a volume name, all volumes are operation.
