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
+ arg 2: pre-install | install | post-config | 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.
+
+The `stack` phase sub-phases are called from `stack.sh` in the following places:
+
+ pre-install - After all system prerequisites have been installed but before any
+ DevStack-specific services are installed (including database and rpc).
+
+ install - After all OpenStack services have been installed and configured
+ but before any OpenStack services have been started. Changes to OpenStack
+ service configurations should be done here.
+
+ post-config - After OpenStack services have been initialized but still before
+ they have been started. (This is probably mis-named, think of it as post-init.)
+
+ extra - After everything is started.
