Creating the configuration file
The blueprint configuration file is a required file that defines the script entry
point for generating the workflow, and the parameters that the blueprint accepts. The file
must be named blueprint.cfg
.
Here is a sample configuration file.
{ "layoutGenerator": "DemoBlueprintProject.Layout.generate_layout", "parameterSpec" : { "WorkflowName" : { "type": "String", "collection": false }, "WorkerType" : { "type": "String", "collection": false, "allowedValues": ["G1.X", "G2.X"], "defaultValue": "G1.X" }, "Dpu" : { "type" : "Integer", "allowedValues" : [2, 4, 6], "defaultValue" : 2 }, "DynamoDBTableName": { "type": "String", "collection" : false }, "ScriptLocation" : { "type": "String", "collection": false } } }
The layoutGenerator
property specifies the fully qualified name of the
function in the script that generates the layout.
The parameterSpec
property specifies the parameters that this blueprint
accepts. For more information, see Specifying blueprint
parameters.
Important
Your configuration file must include the workflow name as a blueprint parameter, or you must generate a unique workflow name in your layout script.
