rbd-volume

rbd-volume - NON-FUNCTIONAL

This Docker container will mount the requested RBD image to a volume. You can then use link to that volume from other containers with the --volumes-from Docker run option.

Environment variables:

• RBD_IMAGE: name of the image (defaults to image0)
• RBD_POOL: name of the pool in which the image resides (defaults to rbd)
• RBD_OPTS: rbd map options (defaults to rw)
• RBD_FS: filesystem of the RBD image (defaults to xfs)
  • NOTE: this container does NOT create the filesystem
• RBD_TARGET: the target mountpoint inside the container (defaults to /mnt/rbd)

Features

• May mount to different targets (allowing multiple instances)
• Go-based maintenance daemon
  • Keeps container running
  • Unmounts on exit signal
• May mount to host filesystem mountpoint (-v /host/path/mountpoint:/mnt/rbd)

Example usage

• docker run --name myData -e RBD_IMAGE=myData -e RBD_POOL=myPool ceph/rbd-volume
• docker run --volumes-from myData myOrg/myApp
