[Puppet Users] Re: Pitching Puppet - How does it work question
Thanks to all, you have helped, as has a few more days of testing. In my first tests, I would change files on the puppetmaster and those changes weren't being made on the clients. It was config problems. I got "the book" and built a consistent puppetmaster. The various doc's on the web don't seem to agree in directory structure and/or aren't complete, so I was having some problems. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Puppet Users" group.

When you say the hash value changed, do you mean on the puppetmaster? In the most used Puppet setup, the master compiles the config for each client, and the client synchronizes the resources. 'Noticed' is a little ambiguous, and I might be misinterpreting, but the client is what is going to compare the current state of the system with the compiled config. Does that answer the question?

Hi Len, Let me take a shot at this. I'm sure I'll be corrected if I'm wrong. It roughly works like this: 1) Client connects to server and asks "what should my configuration be?" 2) Server responds with the desired configuration 3) Client then checks that configuration against what exists 4) Client fixes anything that doesn't match what the server gave it tl;dr: If only the hash value changes, will puppet apply that change? Yes. Who notices the change, the client or the server? Mu. (It's kinda both) Cheers, Eric On Tue, May 05, 2009 at 08:48:34PM -0500, Len Rugen wrote: > I'm trying to pitch puppet to my group.

Who notices > the change, the client or the server? I need to explain how it works. The way I understand it, the server looks at the file when compiling the recipe for the client and calculates a hash value for the file. This hash value is the integrated in the recipe, which in turn is sent to the client. The client then looks at the files described in the recipe and checks if the hash values of the local files match the hash values sent by the server for those files. If they match, nothing happens, as the file is in the right state, if not, the client downloads the file from the server. That's a least the principle. You also have some layers of caching and checking timestamps to see if it's even necessary to recompute a hash, or if you can take the hash value from a previous run, and so on.

The server parses and compiles everything in the manifests to create the expected configuration of the client. It then hands this compiled manifest to the client which checks the state of managed resources against this expected configuration. If things do not match then client chagnes teh computer configuration to match the expected configuration.
