How do you use a variable in a Puppet Manifest?

Question

I am using the WSUS Module with Puppet Master on Centos 7.2. My Puppet Agent servers are running Windows Server 2012.

I want to use a manifest with a variable. However, when the Puppet Agent server has the puppet agent run, it displays "error 400, syntax error." I have tried re-writing the manifest and every variation I could think of. I keep getting some error.

Here is one example of a manifest:

class excellent { class { 'wsus_client': $cool = 'Saturday' server_url => 'http://acme.com', auto_update_option => 'Scheduled' scheduled_install_day => $cool, scheduled_install_hour => 1, } } 

I've tried assigning the variable in braces {}. I tried to use $LOAD_PATH, --custom-dir and FACTERLIB. But I could not figure out how to use any of these three.

I want to change the variable in one place and use it within the scope of its parent class. What should I do?

Answer 1

Have you tried it this way?

class excellent { $cool = 'Saturday' class { 'wsus_client': server_url => 'http://acme.com', auto_update_option => 'Scheduled' scheduled_install_day => $cool, scheduled_install_hour => 1, } } 

Or, this way

class excellent ( $cool = 'Saturday' ){ class { 'wsus_client': server_url => 'http://acme.com', auto_update_option => 'Scheduled' scheduled_install_day => $cool, scheduled_install_hour => 1, } } 

Answer 2

You currently seem to be attempting to assign a value to a variable within the class declaration. Your variable assignment needs to be separate.

$cool = 'Saturday' 

Your class declaration should look like this.

class {'namevar': a => 'a', b => 'b', c => 'c' }
