Extras Hooks
The extras.d directory contains project dispatch scripts that are called
at specific times by stack.sh, unstack.sh and clean.sh. These hooks are
used to install, configure and start additional projects during a DevStack run
without any modifications to the base DevStack scripts.
When stack.sh reaches one of the hook points it sources the scripts in extras.d
that end with .sh. To control the order that the scripts are sourced their
names start with a two digit sequence number. DevStack reserves the sequence
numbers 00 through 09 and 90 through 99 for its own use.
The scripts are sourced at the beginning of each script that calls them. The
entire stack.sh variable space is available. The scripts are
sourced with one or more arguments, the first of which defines the hook phase:
source | stack | unstack | clean
source: always called first in any of the scripts, used to set the
initial defaults in a lib/* script or similar
stack: called by stack.sh. There are four possible values for
the second arg to distinguish the phase stack.sh is in:
arg 2: install | post-config | extra | post-extra
unstack: called by unstack.sh
clean: called by clean.sh. Remember, clean.sh also calls unstack.sh
so that work need not be repeated.
