I though i found a way to do it, and i would like to show it here,
but unfortunately it does not exactly work well, see the comment in
uppercase: global variables seems to be set even if no class from
the .pp file is included.
And i also think now i am going to far into akwardness, just trying
to work around some Puppet limitations, or maybe thinking of Puppet
beyond its scope, as if it was a full featured language
I am wondering now if it is always a good idea to try to do
everything within Puppet. I think if i get time, i will do a generic
script to address this problem, which would be deployed with the usual
set of scripts i deploy on each server, and run it from Puppet. I also
recently went onto another set of Puppet problem, to which i began
implementing a define to do some processing, and ended up having this
define only get the parameters and give it all to a deployed script
that does the processing (just because i needed to loop on the items
of a puppet array).
Anyway, here was my last, and almost working to get the default
stripdown (shows relevant parts) :
##
## mysqld.pp
##
# This variable is global, not defined inside the class, otherwise it
will never be seen as set, due to the dynamic scope
$_service_is_managed_mysqld=1
class mysql::server inherits mysql {
# (...)
}
##
## stripdown.pp
##
define stripdown_service ( $pattern="" ) {
if $pattern == "" {
exec { "stripdown $name stop":
command => "service $name stop",
onlyif => "service $name status",
path => "/usr/bin:/usr/sbin:/bin:/sbin",
}
} else {
exec { "stripdown $name stop":
command => "service $name stop",
onlyif => "pgrep -f \"$name\"",
path => "/usr/bin:/usr/sbin:/bin:/sbin",
}
}
exec { "stripdown $name deactivate":
command => "chkconfig $name off",
onlyif => "chkconfig $name",
path => "/usr/bin:/usr/sbin:/bin:/sbin",
}
}
class stripdown_services::centos {
service {
"autofs": enable => "false", ensure => "stopped";
"avahi-daemon": enable => "false", ensure => "stopped";
# (...)
}
# THIS $_service_is_managed_xxx THING DOES NOT WORK : EVEN IF NOT
CLASS NOT INCLUDED IN THE NODE, THE VARIABLE SEEMS TO BE SET !!!
if $_service_is_managed_squid != 1 { stripdown_service{squid:} }
if $_service_is_managed_lighttpd != 1 { stripdown_service
{lighttpd: pattern=>"lighttpd.conf"} }
if $_service_is_managed_mysqld != 1 { stripdown_service{mysqld:} }
# (...)
}
