Hi Doug,

Environments are solely global in nature, so that file needs to go in your top-level environments directory (and uploaded to your Chef server). I think you’re looking at them backwards. Environments are containers (think development, staging, production) where you may want to have different versions of a cookbook, or different attributes. Typical use cases are things like having a different set of hostnames or credentials that you use in staging vs. production, or locking your production environment to a specific version of a cookbook so that you don’t inadvertently release something before it’s been tested thoroughly. 

This presentation by Seth Vargo may help clear it up, but feel free to ask more questions if I didn’t explain it well enough: https://speakerdeck.com/sethvargo/chef-plus-environments-equals-safer-infrastructure

I'm missing an important detail with chef environments. I created an environment called 'eu2-prod' with the knife command, and can view and edit it.

In my cookbook I have created the environments directory into which I have deposited an environment file called 'eu2-prod.json'. It looks like this:

{
  "name": "eu2-prod",
  "description": "",
  "cookbook_versions": {
  },
  "json_class": "Chef::Environment",
  "chef_type": "environment",
  "default_attributes": {
  },
  "override_attributes": {
  }
}

All this has been uploaded to the chef server. However, when the client runs, it can't find the data from the eu2-prod environment. 

Looking at the chef GUI, I'm still confused. The cookbook itself doesn't show the environments/ directory, but rather has a drop-down at the top which lets me select which environment I am looking at. No matter which environment I pick, 'None', '_default' or 'eu2-prod' I can't see any of the data from the environments/eu2-prod.json file.

If I go over to the Environments global section in the UI, also there's no data there. I wouldn't expect to see any data there anyway, as I imagine that's environment data that's, err... global in scope. 

Thanks,
Doug
