Workflows template

Workflow are defined using a YAML manifest with the following structure:

name: "insert_workflow_name_here"
tasks:
# these are the tasks that will be executed sequentially to complete a trial (configure the system under tests with the parameters optimized by Akamas )
- name: "insert_here_name_of_task"
  # an operator specifies which type of task should be used
  operator: "insert_here_which_operator_to_use_for_the_task"
  # each operator accepts different arguments necessary to specify how it should behave
  arguments:
	...

with the following properties:

Name	Type	Value Restrictions	Required	Default	Description
name	string	-	yes	-	The name of the task.
operator	string	-	yes	-	The operator the task implements: the chosen operator affects available arguments.
critical	boolean	-	no	true	When set to true, task failure will determine workflow failure.
alwaysRun	boolean	-	no	false	When set to true, task will be executed regardless of workflow failure.
collectMetricsOnFailure	boolean	-	no	false	When set to true, failure of the task will not prevent metrics collection.
arguments	list	Determined by operator choice	yes	-	Arguments list required by operators to run.

The full list of Operators and related options is provided on the Workflow Operators pages.
