-- Use one of the following lenses to modify other fields as desired:
--
-- * 'ciCustomImageName' - The name for your custom image.
--
-- * 'ciUserData' - A launch script you can create that configures a server with additional user data. For example, you might want to run @apt-get –y update@ .
--
-- * 'ciKeyPairName' - The name of your key pair.
--
-- * 'ciInstanceNames' - The names to use for your new Lightsail instances. Separate multiple values using quotation marks and commas, for example: @["MyFirstInstance","MySecondInstance"]@
--
-- * 'ciAvailabilityZone' - The Availability Zone in which to create your instance. Use the following format: @us-east-1a@ (case sensitive).
--
-- * 'ciBlueprintId' - The ID for a virtual private server image (e.g., @app_wordpress_4_4@ or @app_lamp_7_0@ ). Use the get blueprints operation to return a list of available images (or /blueprints/ ).
--
-- * 'ciBundleId' - The bundle of specification information for your virtual private server (or /instance/ ), including the pricing plan (e.g., @micro_1_0@ ).
