How to run an errand:

bosh run errand ERRAND_NAME [--download-logs] [--logs-dir DESTINATION_DIRECTORY]

ref: http://bosh.io/docs/sysadmin-commands.html#errand

Assuming you have already marked the deployment job 'lifecycle' as 'errand' in your manifest

ref: Jobs Block section of http://bosh.io/docs/deployment-manifest.html

Like Ben Moss mentioned in his comment, a new VM is created for running an errand job. The errand VM does not stay around after the errand completes. Errand is a short lived job and can be run multiple times
