INSTALLING OPENSTACK USING SALTSTACK
© Copyright 2014 Hewlett-Packard Development Company, L.P.
¡ I’ve been poking at Linux servers back in late 90’s ¡ Actively trying to replace myself with small scripts.
§ Bash § Cfengine § Puppet § Capistrano § Chef § Salt
WHO IS THIS GUY?
© Copyright 2014 Hewlett-Packard Development Company, L.P.
¡ You might have tried DevStack to try OpenStack. ¡ You have setup a Salt Master before. ¡ You want to see how I solved some of my headaches
using Salt. ¡ You are want something answered. ¡ The other rooms were full and this one has an open
power outlet.
WHY ARE YOU HERE?

¡ /etc/keystone ¡ /etc/nova ¡ /etc/glance ¡ /etc/swift ¡ /etc/????
THINGS CHANGE.
© Copyright 2014 Hewlett-Packard Development Company, L.P.
¡ Look beyond your current infrastructure. ¡ Think about how others have deployed OpenStack. ¡ Make the decision early to keep secrets out of your repos.
NOW WHAT?

PILLAR TOP.SLS base: '*': - users - groups - headers - openstack - secrets dbaas_ae1_az1: 'ps-ae1az1-db*': - endpoints-ae1az1-v1 - secrets-ae1az1-v1 dbaas_ae1_az2: 'ps-ae1az2-db*': - endpoints-ae1az2-v1 - secrets-ae1az2-v1
The top.sls is actually a symbolic link to the file top-ae1.sls
openstack.sls is a symbolic link to openstack-ae1.sls
These are links too but slightly different

PILLAR ENVIRONMENTS
It is much easier to diff two or more files than it is to search one long file.

Notice there is nothing here about
the MySQL DB
No RabbitMQ either

¡ If you only plan to run it only once you most likely don’t need it in your top.sls
¡ Installing RabbitMQ ¡ Installing MySQL DB ¡ Creating your OpenStack API Endpoints ¡ Creating your OpenStack users ¡ Modifying the MySQL DB ¡ Create a one-off state directory for one off .sls ¡ Use unique names for your .sls fi les ¡ <project>-<ticket number>.sls ¡ Prevent executions on the wrong host ¡ Use simple lock files and or grain values to prevent second runs
LEAVE IT OUT OF THE TOP.SLS

¡ What new features are out there ¡ Check in on IRC and ask questions ¡ Hangout and answer some questions ¡ Are you alone in your company working with Salt?
