rbd-unlock

A convenience container to release a lock on an RBD image

Make sure to pass your /etc/ceph path as a volume/bind-mount.

It uses the following environment variables, if present:

  • IMAGENAME: this should be of the form poolName/imageName, and you may override this by passing the image name as the first argument
  • LOCKNAME: this is name of the lock, and you may override this by passing the lock name as the second argument. The LOCKNAME will default to the HOSTNAME of the machine.
  • LOCKID: this is the id of the lock, and you may override this by passing the lock id as the third argument.
  • ETCD_LOCKID_KEY: this is the key name from where the LOCKID should be read (thus obviating and overriding LOCKID)
  • ETCDCTL_PEERS is a comma seperated list of etcd peers (e.g. http://192.168.2.4:4001)
  • etcdctl is used to get the key, so any environment variable which acts upon etdctl will be honored within the execution.

Example:

docker run --rm -v /etc/ceph:/etc/ceph ceph/rbd-unlock myPool/myImage myLockName lockId
