[chef] Re: Querying a Chef server through it's API

[ANGELA EBIRIM < >]

Hi Brandon,

I've been using Ridley to actually query a test Chef server and it worked fine (always the way!). However when I tried it with a dev Chef server received the following error https://github.com/RiotGames/ridley/issues/301. Apparently I discovered a bug that they have now flagged up as a potential feature. If you try to find a databag on a Chef server, using Ridley, you may receive a 301 error. Unfortunately you don't get any information on what the new location for the databag should be!

Once I find a solution, I'll post it here just in case someone else has the same problem.

Thanks for your help!

Regards

Hi Angela,

It sounds like you might be getting a nil or empty response back from the chef server. I would try running the same thing in a pry/irb session and see what the return value looks like from rest.get_rest('/nodes').

For what it's worth, you might also want to give ridley a try.

Thanks,

Brandon

Hello everyone,

I'm new to Chef so be gentle!

I'm trying to query a Chef server through it's API and have developed the following code:-

require 'chef/config'

require 'chef/log'

require 'chef/rest'

chef_server_url = "http//chef.prod.practor.service"

client_name = "ace67"

signing_key_filename=File.dirname(__FILE__) + "/.chef/ace67.pem"

 

rest = Chef::REST.new(chef_server_url, client_name, signing_key_filename)

nodes = rest.get_rest("/nodes")

 

nodes.keys.each do |node_name|

    puts "Node name: #{node_name}"

end

It's a simple Ruby script to query the Chef server. through it's API, for a list of nodes. However when I run the script, I get an error of TypeError: can't dup NilClass. It's occurring on the nodes  =  rest.get_rest("/nodes") line.

I'm running Chef version 11.16.2

I'd appreciate any assistance with this.

Many thanks
