4.2. API Examples Using Ruby
The following examples describe how to perform various tasks using Ruby to communicate with the Satellite API.
Important
These are example scripts and commands. Ensure you review these scripts carefully before use, and replace any variables, user names, passwords, and other information to suit your own deployment.
4.2.1. Creating Objects Using Ruby
The following script connects to the Red Hat Satellite 6 API and creates a new organization, and then creates three environments in the new organization. If the organization already exists, the script uses that organization. If any of the environments already exist in the organization, the script raises an error and quits.
#!/usr/bin/ruby require 'rest-client' require 'json' url = 'https://satellite6.example.com/api/v2/' katello_url = "#{url}/katello/api/v2/" $username = 'admin' $password = 'changeme' org_name = "MyOrg" environments = [ "Development", "Testing", "Production" ] # Performs a GET using the passed URL location def get_json(location) response = RestClient::Request.new( :method => :get, :url => location, :user => $username, :password => $password, :headers => { :accept => :json, :content_type => :json } ).execute JSON.parse(response.to_str) end # Performs a POST and passes the data to the URL location def post_json(location, json_data) response = RestClient::Request.new( :method => :post, :url => location, :user => $username, :password => $password, :headers => { :accept => :json, :content_type => :json}, :payload => json_data ).execute JSON.parse(response.to_str) end # Creates a hash with ids mapping to names for an array of recods def id_name_map(records) records.inject({}) do |map, record| map.update(record['id'] => record['name']) end end # Get list of existing organizations orgs = get_json("#{katello_url}/organizations") org_list = id_name_map(orgs['results']) if !org_list.has_value?(org_name) # If our organization is not found, create it puts "Creating organization: \t#{org_name}" org_id = post_json("#{katello_url}/organizations", JSON.generate({"name"=> org_name}))["id"] else # Our organization exists, so let's grab it org_id = org_list.key(org_name) puts "Organization \"#{org_name}\" exists" end # Get list of organization's lifecycle environments envs = get_json("#{katello_url}/organizations/#{org_id}/environments") env_list = id_name_map(envs['results']) prior_env_id = env_list.key("Library") # Exit the script if at least one life cycle environment already exists environments.each do |e| if env_list.has_value?(e) puts "ERROR: One of the Environments is not unique to organization" exit end end # Create life cycle environments environments.each do |environment| puts "Creating environment: \t#{environment}" prior_env_id = post_json("#{katello_url}/organizations/#{org_id}/environments", JSON.generate({"name" => environment, "organization_id" => org_id, "prior_id" => prior_env_id}))["id"] end
