Using Puppet to setup PostgreSQL for Keystone on Fedora

Using Puppet to manage software configuration makes sense. Setting up PostgreSQL support for Keystone development and testing has been my excuse to learn it.

sudo yum install puppet
sudo puppet module install puppetlabs/postgresql

Then create a file /etc/puppet/site.pp

Put this line in it:

class { 'postgresql::server': }

postgresql::db{ 'keystone':
  user          => 'keystone',
  password      => 'keystone',
  grant         => 'all',
}
sudo  puppet apply --verbose /etc/puppet/site.pp

Confirm that postgresql is running:

systemctl status postgresql.service

Should get you

postgresql.service - PostgreSQL database server
	  Loaded: loaded (/usr/lib/systemd/system/postgresql.service; disabled)
	  Active: active (running) since Thu, 03 Jan 2013 13:26:46 -0500; 43min ago
	 Process: 17529 ExecStop=/usr/bin/pg_ctl stop -D ${PGDATA} -s -m fast (code=exited, status=0/SUCCESS)
	 Process: 17553 ExecStart=/usr/bin/pg_ctl start -D ${PGDATA} -s -o -p ${PGPORT} -w -t 300 (code=exited, status=0/SUCCESS)
	 Process: 17545 ExecStartPre=/usr/bin/postgresql-check-db-dir ${PGDATA} (code=exited, status=0/SUCCESS)
	Main PID: 17556 (postgres)
	  CGroup: name=systemd:/system/postgresql.service
		  ├ 17556 /usr/bin/postgres -D /var/lib/pgsql/data -p 5432
		  ├ 17557 postgres: logger process   
		  ├ 17559 postgres: writer process   
		  ├ 17560 postgres: wal writer process   
		  ├ 17561 postgres: autovacuum launcher process   
		  └ 17562 postgres: stats collector process

Test we can connect to the PostgreSQL command line tool:

psql -h localhost -U keystone keystone 
Password for user keystone: 
psql (9.1.7)
Type "help" for help.

keystone=> \d

To run the Keystone unit test test against the database, alter the file /opt/stack/keystone/tests/backend_sql.conf. Comment out the sqlite connection line, and uncomment the postgresql line.

[sql]
#connection = sqlite://
#To Test MySQL:
#connection = mysql://root:keystone@localhost/keystone?charset=utf8
#To Test PostgreSQL:
connection = postgresql://keystone:keystone@localhost/keystone?client_encoding=utf8
idle_timeout = 200

Then you can run the unit tests with

./run_tests.sh -N test_sql_upgrade

If the tests fail (and they will), they will leave the database in an unusable state. You can drop the database and recreate with puppet:

sudo su postgres -c "dropdb keystone"
sudo  puppet apply --verbose /etc/puppet/site.pp
