[chef] Re: Re: Is Supermarket replacing Berkshelf-API server?

[Christopher Webber < >]

Probably worth mentioning at this point that neither the Berkshelf API server nor Supermarket do any depsolving. They provide a complete index of what they know about and Berkshelf the client handles the actual depsolving.

Is there any difference in how berkshelf-api and supermarket resolve cookbook's dependencies? We used berkshelf-api a while ago and having multiple sources in Berksfile it's wasn't clear which one will be used for each dependency.

Bernie,

That’s exactly what Supermarket/Chef Server are. In fact, the Chef Server, once it has the Berkshelf-style universe endpoint, will work pretty much exactly like a yum/apt repo; you’ll query it for the collection of cookbooks is has, then dependency resolve based on the results & what you need.

Right now, you need your own Berkshelf API server that’s indexing your Chef Server to do that for your private cookbooks. For public, community cookbooks, the Supermarket provides its own Berkshelf `universe` endpoint to provide that sort of depsolving.

Supermarket just happens to offer a web UI on top of all of that, which does require the “fancy” bits you speak of, but at its heart, it’s an artifact store & dependency tree.

Why does a cookbook repository need to live behind a fancy server anyway?
A repository, by nature, is static. Wouldn¹t a Yum or Apt style repo with
just files and an index be good enough and simpler? Seems like an S3
bucket and an indexer would be all you need, no?
