Hello, I'm new to puppet using a puppet-master. And I couldn't figure out
what's the best practice I need.
My context :
- puppet-master with a puppet dashboard is setup and running
- few modules are ready and fully fonctionnal (tested using vagrant and
puppet apply)
- there are some nodes in different zone (such as dev, QA, preprod, prod,
...)
In fact,
I've some shared resources in a zone :
- SQL data-base
- Mail server
- ...
And my apps are running in several nodes (for the same zone) :
- one node as the front-end role
- another as the back-office role
-
So I'd like to setup the configuration variables in one place (by zone) and
reuse it among nodes in the same zone.
(Obviously, every node as some specific configurations)
My question is :
- How can I share some variable svalues among nodes (like those in the same
zone for exemple)?
What to do ?
- I tryed to put the zone specific variables in a dedicated configuration
file andimport it in the relevant nodes. But this didn't worked telling me
that I redefined variable (as soon as I've several zones)
- Should I create a template node by zone with thoses common varaibles?
- Is there any other way to do?
Sample files are below:
Sample class :
class p2es::plateforme_stockage(
$env ='integration',
$yumrepo_host ='10.10.25.5',
$version =undef,
$ensure =undef,
$rwpwd=admin,
$ropwd=reader,
$probepwd =probe,
$bddhost =10.10.25.23,
$bddlogin =l_ps,
$bddpwd =l_ps,
$mailhost =smtp.XXX.fr,
$mailto =dev-p...@xxx.fr,
$mailfrom =dev-p...@xxx.fr){
# Repo YUM
class{ p2es::repo:
env = $env,
yumrepo_host = $yumrepo_host
}
Sample node :
node /^.*ps.*preprod.*$/ inherits base {
# Partie de la conf mutualisée
import '../configuration/p2es_ps_conf_preprod'
# indiquer l'environnement cible
$env= 'preprod'
# Le soft
class{ p2es::plateforme_stockage:
env = $env,
yumrepo_host = $YUM_REPO_HOST,
version = $PS_VERSION,
ropwd = $JMX_RO_PWD,
rwpwd = $JMX_RW_PWD,
probepwd= $PSI_PROBE_PWD,
bddhost = $BDD_HOST,
bddlogin= $BDD_LOGIN,
bddpwd = $BDD_PWD,
mailhost= $MAIL_HOST,
mailto = $MAIL_TO,
mailfrom= $MAIL_FROM
}
}
Sample configuration :
$YUM_REPO_HOST=10.10.25.5
$DATASRC_HOST=10.10.25.23
$DATASRC_LOGIN=l_pe
$DATASRC_PASSWORD=l_pe
$MONGODB_HOST=10.10.25.23

Thank you for your help
Hi Sylvain,
Check out hiera. It contains loads of awesome, and should allow you to feed the
nodes relevant variables for each zone.
