Automate host insertion/update

Gus · June 3, 2010, 5:11pm

Hi All!

I am looking for a way to automate virtual machine provisioning with
puppet.

For this, I am considering to use foreman external node capability to
keep the specification off all nodes known to puppet.

My question is, is there an automated way to insert or alter a host in
foreman data model without using the web interface… such as a Restful
API for instance…

Thanks in advance,
Gus

Hi Gus,

Foreman does support restful API.

there are a couple of things to notice:

Rails keep an authentication (cross site scripting) headers, so you will
need to use those (see an example here: http://gist.github.com/239561)
All values which are in dropdown boxes, are usually plain numerical id
representation, might need to fetch the html to know the right text values
(which fit to the numerical ids).

another option is to use the script/runner in rails, which allows you to
create the machines directly, but I agree that the restful API is probably
better on the long run.

let me know if you need any help,
Ohad

a little play around with the api, created a simple machanize based
solution:

gist.github.com

https://gist.github.com/ohadlevy/425171

machinze to fetch values from foreman

#!/usr/bin/ruby

require "rubygems"
require 'net/http'
require "mechanize"

agent = Mechanize.new
url = "http://localhost:3000"

new_host_url = "#{url}/hosts/new"

This file has been truncated. show original

you could extend this to query and set the right values.

cheers,
Ohad

Hi!

I have managed to create a host through using REST with mechanize.

However, I'm having some trouble to click on the Add parameter link in order
to create a
host with more than one variable…

Has anyone an example of this?

Cheers,
Gus

Hi Gus,

just updated the gist to include a second parameter.

Let me know if it works for you,

Thank you Ohad.

I have already tried this. It seems that mechanize validates the form before
posting the data. This is why I need to clink add parameter link to retrieve
the new form fields.

To solve this, I have done exacty what your last gist suggest, but without
using mechanize…

If I set Content-Type header to application/json, rails ignores the
authtencitity token, making things a little bit easier…

Cheers,
Gus
