catch up!

Last session• all-in-one VM– default configuration (nova, keystone, glance, horizon,

cinder, openstack*-clients)

#OSATH Environment• Ubuntu (mostly used), Centos• VirtualBox, VM Player

configure

local.conf (localrc)• your variable settings• overrides any variables set in stackrc

stackrc• provides info about git repo and branch, image download

location• this file shouldn't be modified,

use local.conf|localrc instead

stack.sh• opinionated sh script used for OpenStack developer

installation (uses screen)

your setup

Customize localrc and local.conf• contain all non-default local configuration in a single file• be backward-compatible with localrc to smooth the

transition process• allow settings in arbitrary configuration files to be changed

structure

local.conf• Follows INI file format

[[<phase>|<config-file-name>]]

• <phase> as defined in stack.sh• <config-file-name> is the configuration file name– Ex.

[[post-config|$NOVA_CONF]]

defined phases

• local – extracts localrc from local.conf before stackrc

is sourced • post-config – runs after the layer 2 services are configured and before

they are started • extra – runs after services are started and before any files in extra.d are executed

• post-extra – runs after files in extra.d are executed

sample single file

local.conf[[local|localrc]] FIXED_RANGE=10.254.1.0/24NETWORK_GATEWAY=10.254.1.1 RECLONE=TrueLOGDAYS=1 LOGFILE=$DEST/logs/stack.sh.log SCREEN_LOGDIR=$DEST/logs/screenADMIN_PASSWORD=passDATABASE_PASSWORD=$ADMIN_PASSWORDRABBIT_PASSWORD=$ADMIN_PASSWORD

some adjustment(s) …

Convert EXTRA_OPTS from (localrc): EXTRA_OPTS=api_rate_limit=False

to (local.conf): [[post-config|$NOVA_CONF]] [DEFAULT] api_rate_limit = False

• EXTRA_OPTS (and other variables) are deprecated
