Hello puppet users, I have recently started dabbling in custom types and providers in order to solve some problems at work. I now find myself needing to have 2 custom providers that leverage a common function to fetch data from a web service and I very much do not want to have 2 copies of this function in my code base. I'd like to hear how others have addressed this kind of problem, and I'm certainly amenable to alternatives if there's a better way than the types/providers.
Here is what I'm trying to do and the constraints I cannot currently get around. 1) I am dynamically configuring nginx virtual hosts and adding lines to /etc/hosts for internal routing (cloud hosted boxes all have external ip's and I need the various names we support to resolve to internal ip's of the load balancer) 2) The data I need for this configuration (fqdn's, certs, and keys) cannot be determined on the puppet master because the data source is a web service (delivers a json array) I install and configure and must be running on the node before I can query it. I already have the custom nginx provider written and working to configure the virtual hosts, but I also need the fqdn's available from the same web service and I would like to reuse the function that fetches and parses the json from the web service. This second custom provider will be responsible for adding the appropriate lines to /etc/hosts to handle my internal routing problem. Questions: 1) Is there a good way to have an arbitrary ruby module and function that I can require in both of my providers? I'm reasonably good with ruby, but we're not a ruby shop and I'd rather not have to get into packaging and managing gems for the purpose of sharing a 20 line function in 2 places. 2) Is there a way for custom providers to return data to a manifest? I'd rather use the file_line resource to handle my /etc/hosts needs, but I don't know of a means of returning data from a resource declaration (which would be my existing custom type using the nginx provider) that I could use in another resource. 3) Is there a way I can pass arguments to an executable fact? I don't know of one, but I suppose I could set environments variables (i.e. things like the web service host, port, user, password, etc...) provided that executable facts run each time they are referenced in a manifest?
