if we passed shortname, get fqdn

facts_to_hash(facts) click to toggle source

Parse the fact output from puppetdb into a simpler hash

v4 apit returns facts as an array, with each element a hash like

{“certname”=>“some_host”,

"environment"=>"some_env",
"name"=>"memorysize",
"value"=>"3.70 GiB"},
# File lib/whats.rb, line 56
def self.facts_to_hash(facts)
  node_facts=Hash.new
  facts.each do |fact|
    node_facts[fact["name"]] = fact["value"]
  end
  return node_facts
end
get_facts(puppetdb_host,puppetdb_port,fqdn) click to toggle source

get all facts for the given node

# File lib/whats.rb, line 41
def self.get_facts(puppetdb_host,puppetdb_port,fqdn)
  uri=URI.parse("http://#{puppetdb_host}:#{puppetdb_port}/pdb/query/v4/nodes/#{fqdn}/facts")
  response = Net::HTTP.get_response(uri)
  facts=JSON.parse(response.body)
  return(facts)
end
node_test(puppetdb_host,puppetdb_port,fqdn) click to toggle source

Query to see if the node we’re looking for exists

# File lib/whats.rb, line 29
def self.node_test(puppetdb_host,puppetdb_port,fqdn)
  test_uri=URI.parse("http://#{puppetdb_host}:#{puppetdb_port}/pdb/query/v4/nodes/#{fqdn}")

  test_body=JSON.parse(test_response.body)
  if test_body.key?("error")
    return false
  else
    return true
  end
