Hello Everyone,
I have a very basic code to stop and disable few services which I am
running for CentOS/RHEL 6/7 servers.

Is it possible to not run this code when the OS is CentOS/RHEL 7 and the
stop_services value is auditd.
Here are a couple of ways to do this (all untested):
If you are on 3.x and using the future parser, or using 4.x you can add
and remove from arrays directly in the language with '+' and '-'. If on
earlier versions you need to use the 'delete' function from stdlib.
# for 3.x (no future parser)
#
$stop_services = ["ip6tables","iptables","auditd","cups"]
if $::osfamily == 'RedHat {
$excluded_services = ['auditd']
}
else {
$excluded_services = []
}
$services_to_stop = delete($stop_services, $excluded_services)
service { $services_to_stop:
ensure=>stopped,
enable =>false,
}
With the 4.x (3.x future) parser you can also use a case expression to
produce a value (which may be more convenient if you will have more than
a single special case.
$stop_services = ["ip6tables","iptables","auditd","cups"]
$excluded_services = case $::osfamily {
'RedHat': { 'auditd' }
default: { }
}
service { $stop_services - $excluded_services :
ensure=>stopped,
enable =>false,
}
Or you can iterate:
# using conditional logic
#
["ip6tables","iptables","auditd","cups"].each |$service| {
unless $::osfamily == 'RedHat' and $service == 'auditd' {
service { $service :
ensure => stopped,
enable => false,
}
}
}
# using 'filter'
#
["ip6tables", "iptables", "auditd", "cups"].filter |$service| {
$::osfamily != 'RedHat' and $service != 'auditd'
}.each |$service| {
service { $service :
ensure => stopped,
enable => false,
}
}
