Have a class deploy a module in Puppet?

  • 772

I've read a lot of different sources, and I just can't decide what is the best way to handle deployment of modules to nodes/hosts nor have I gotten some of them to work. I have created everything in modules.

That being said, when I was testing I was deploying the modules like this;

node 'basetesting' {
        include fail2ban
        include nrpe
}

node 'test-dev' inherits 'basetesting' {
}

However, I've created a lot of modules and realized that my servers will vary on what their role is (application, web, etc). There is a set of base requirements all of them have. So I essentially want a node to have the base. Then have their required modules, which I believe would look something like this;

node 'basetesting' {
        include fail2ban
        include nrpe
}

node 'test-dev' inherits 'basetesting' {
            include httpd
}

Then I realized ... that I would have to make a definition for every single node. Which, I guess wouldn't be bad, but I imagine if you had 50+ servers, that might become quite the nodes.pp file.

Is there a better way to do this?

  1. The solution I use is regexing the node names:

    node 'www\d.domain.com' inherits 'webserver' {}

    That way all of my www1, www2, www3, etc get the right setup. Using descriptive server names also makes it easier for new people to understand how your system as a whole works.
