Can I get a listing of host<>environment from the foreman API? Or should
I go directly to the database?
Thx,
Larry Fast
PS: I just got full round trip working with my pre-existing agents.
agent=>puppetmaster=>foreman-ENC=>foreman-yaml=>puppetmaster=>agent. After
2 days, Foreman is already providing visibility on stuff that was
previously hidden.
Yes, you can get details of a host and/or environment from the API. Here's a simple curl example.
curl -u admin:secret -H "Accept:application/json" http://0.0.0.0:3000/api/hosts/example.host.com
curl -u admin:secret -H "Accept:application/json" http://0.0.0.0:3000/api/environments/production
The current default API version is v1. We are working on v2.

Joseph

Thank you all! This is a very helpful community! Let me summarize what
I've learned. And again, correct me if anything is misrepresented.
From any GUI page I can filter using the search rules in the filter box
environment=dev23 AND os~cent
Using curl I can wrap the same text as used in the GUI with something like
this:
curl -u admin:secret -H "Accept:application/json"
http://localhost/api/hosts?search="environment=dev23 AND os~cent"
In ruby I can do something like this (but I haven't worked out uid/pwd/SSL
yet):
require 'rest_client'
require 'json'
require 'pp'
myJson = RestClient.get('http://localhost/api/hosts?', :params =>{ :search
=> "environment=dev23" })
myHash = JSON.parse(myJson)
pp myHash
And I thought I saw reference to a ruby syntax like this:
require 'foreman'
myJson = foreman( … ) - so I'm guessing there's a foreman class I can
use ???
My final comment/question is about more generalized SQL-ish queries. What
I see so far is that each API page:
So if I want to collect a broader cross-section of data I would need to go
directly to the database? Or is there an API page that can return broader
search results? Eg. I want to see hosts.environment & hosts.facter.XYZ
for a list of hosts filtered by os=centOS.
Cheers,
Larry Fast
> It's not implemented yet, but I am considering to add to the API the
option for the user to specify the fields in the response as well as to
expand the child relationships. Is this what you mean?
Yes, that's it exactly. I'm looking foward to seeing it.
Thanks again,
Larry Fast
Thanks Joseph.
So the process of getting my list of host<>environment is three-ish steps
One more question. In Ruby, what's the best way for getting this data into
a hash?
Thanks,
Larry
Try this using params[:search]. Foreman uses the scoped_search gem (github.com/wvanbergen/scoped_search).
Try it on the UI. There is an auto-completer so it's easy to learn.
curl -u admin:secret -H "Accept:application/json" http://0.0.0.0:3000/api/hosts?search='environment=production'

Why don’t you search for an environment? e.g.
OK, but I can’t find an example of how to construct that. I’m guessing that I would use the search API but I haven’t seen any complete examples of the syntax. Something like this I suppose:
curl -u admin:secret -H “Accept:application/json” http://0.0.0.0:3000/api/ hosts?“hosts.environments.environments.name=foo”
And if I’m barking up the wrong tree, please point me to the right tree :^)

Why don't you search for an environment? e.g.

Thanks for this. I couldn't find how to do a search anywhere in the API
docs.
