docker_run_dumpzodb.sh

#!/bin/bash
#
# dump_db.sh - build zendev/devimg.
#
# This script assumes that zendev/devimg already exists; see build.sh.
# This script runs dump_zodb.sh in zendev/devimg with several key
# directories in the image bind-mounted to source directories in the developer's
# local sandbox.  The dump_zodb.sh script creates a clean base zodb from the XML files or gz file
# on the developer's local sandbox (zenoss-prodbin/Products/ZenModel/data).  It then migrates
# the database to the latest version based on the migrate scripts found in ZenModel/migrate.
# Finally, it dumps an updated set of xml files and an updated .gz file back out to 
# zenoss-prodbin/Products/ZenModel/data
#
# Required Arguments (specified as environment variables):
# TAG         - the full docker tag of the devimage to use (e.g. zendev/devimg:<envName>)
# ZENDEV_ROOT - see the description in makefile
# SRCROOT     - see the description in makefile
#
# Optional Argument
# ZENWIPE_ARGS - set to '--xml' to load DB from XML files, or leave empty to use .gz file
