Can metadata.json include dependencies of git modules

asked 2016-08-31 14:40:41 -0500

Module 'A' depends on module 'B' and they both are in git - Is there a way to include them in metadata.json - Or does metadata.json only accept dependencies of modules that are in the puppet forge? Please provide examples. Thank you!

Are you talking about execution order of modules in terms of prerequisite or using code of module A in module B, like we do for standard libraries?

It's more of one module as a prerequisite for another module.

puppet docs: latest refererence on modules metadata § example

"dependencies" is an Array[Struct[{name => String[1], version_requirement => String[1]}]]

The name attribute has to [or at least should] match a module's name (what's written in its metadata.json).

So in your case metadata.json of your module redsmile/A contains:

"dependencies": [
  {"name": "redsmile-B", "version_requirement": "> 0.0.0 < 1.0.0"}
],

whereas the metadata.json of the module redsmile/B

"name": "redsmile-B",

Where and how the module's are stored is irrelevant for the metadata.json. You can provide a link in your readme.md where needed modules can be retrieved, or, for convenience, upload them to puppet forge, since that let's you just puppet module install redsmile-A automatically fetching required modules.

I Think the OP is asking about modules that are NOT forge modules, that are only stored in source control. Some module managers (r10k/puppet-librarian/code deploy?) support a Puppetfile for module dependency resolution, which includes git repositories. I don't believe it is in the current metadata.

Yes, I'm asking about modules that are NOT forge modules. For certain legitimate reasons, it couldn't be uploaded to forge but would still need to be in house. I don't think metadata.json supports anything other than puppet forge modules. Thanks for the insight though. Appreciate it.

Yes, AFAIK the PMT (puppet module tool) does only resolve dependencies for modules their dependencies are hosted at Forge, too. And, as far as I've looked, it can handle at most one module_repository URI. That's where modules as packages *.deb *.rpm *.yum can become handy.

Yes, all that i read suggests that metadata.json is purely for puppet forge modules only.
