Hi,
I have an Exec which requires a lot of packages (15-20):
Exec { ''name'':
...
require => [ Package[''first''],
Package[''second''], Package[''third''], ... ]
}
Is there a way to shorten this list and make it easier to read?

That seems excessive. What does that exec statement look like, at the moment, the only way I can imagine an exec statement requiring that number of packages is by it being a pipeline of 15 commands, each of which comes from a separate package.

Hi Matt, It installs PHP from source. The required packages are mostly libraries (libxml2-dev, libpcre3-dev, etc). Here is the file if it helps to better understand my problem: https://www.assembla.com/code/nooku-server/git/nodes/master/puppet/modules/php/manifests/install.pp The exec is on line 175.

Hi, Thanks, I will look into tags, it could be solution indeed. I also thought about moving those packages into a separate class (eg. packages.pp), was just wondering what my options are if I leave them in install.pp. Gergo Erdosi On Tuesday, March 12, 2013 11:57:41 AM UTC+1, R.I.

You should make a package and use that instead of compiling php on demand. Use fpm, it makes it as easy as using tar. -- You received this message because you are subscribed to the Google Groups "Puppet Users" group.

I know, this is not the first time I hear packages are the preferred way, and I completely agree. We will look into packaging later, but for now we needed to get the script to work. This is the first version, I already have ideas how to improve it. Gergo Erdosi On Tuesday, March 12, 2013 12:10:43 PM UTC+1, R.I.

Also, putting this into a variable and using that instead, may improve your situation: $packages = [''first'', ''second'', ''third'', ...] package { $packages: ensure installed } exec { "foo": require => Package[$packages] } Best Regards, David -- You received this message because you are subscribed to the Google Groups "Puppet Users" group.

Hi David, Nice, didn''t know I can use multiple packages inside Package. Thanks!

Ways I imagine it might fail include: - Puppet attempts to manage a single package whose name is a concatenation of the names in $packages ("firstsecondthird...") - Puppet manages only the first package listed in $packages, ignoring the others - Puppet does not correctly detect when the packages are already installed, and therefore attempts to install them on every run If it does none of those things then I have great difficulty believing that it does not create a separate Package resource for each element of $packages, and therefore indeed run the package manager once for each. And if it in fact behaves exactly as promised, then that constitutes undocumented behavior, and it is therefore unsafe to rely upon. So don''t do that.

I didn''t test it on many platform, but it works quite well on rpm-based providers.> > And if it in fact behaves exactly as promised, then that constitutes undocumented behavior, and it is therefore unsafe to rely upon.It not so undocumented. You don''t just convert a array to a string, you get an empty separator [''a'', ''b''] is converted to ''ab'', for what I saw in many of my mistakes. So someone was thinking about my use case and add the code to have a '' '' separator for the rpm command.> > So don''t do that. > > > John-- You received this message because you are subscribed to the Google Groups "Puppet Users" group.
