unstack.sh

#!/usr/bin/env bash

Stops that which is started by stack.sh (mostly) mysql and rabbit are left running as OpenStack code refreshes do not require them to be restarted.

Stop all processes by setting UNSTACK_ALL or specifying --all on the command line

Keep track of the current devstack directory.

Import common functions

Import database library

source $TOP_DIR/lib/database

Load local configuration

Destination path for service data

DATA_DIR=${DATA_DIR:-${DEST}/data}

Get project function libraries

source $TOP_DIR/lib/baremetal
source $TOP_DIR/lib/cinder
source $TOP_DIR/lib/horizon
source $TOP_DIR/lib/swift
source $TOP_DIR/lib/quantum

Determine what system we are running on. This provides os_VENDOR, os_RELEASE, os_UPDATE, os_PACKAGE, os_CODENAME

Shut down devstack's screen to get the bulk of OpenStack services in one shot

SCREEN=$(which screen)
if [[ -n "$SCREEN" ]]; then

    if [[ -n "$SESSION" ]]; then
        screen -X -S $SESSION quit
