Hi,

I’ve developped a function that might replace file based on template according to exec result :

Functions¶

    define configtemplate ($template,$file,$condition) {
            exec { "check_${file}_${condition}":
                    command => '/bin/true',
                    unless       =>  "/bin/grep -qF '${condition}' '${file}'";
            }
            file { "$file":
                    path => $file,
                    content => template($template),
                    require => Exec["check_${file}_${condition}"],
            }
    }

Named : template if ip of server not present¶

    configtemplate { "/etc/bind/named.conf":
            template => "named/named.conf.erb",
            file => "/tmp/named.conf",
            condition => "$ipaddress",
    }

The problem is that the function is not testing the result of exec. Therefore, file is pushed at every call.
