loop - run an action within a loop

Note

This article is about a specific action.
On how to call actions in general, refer to Calling actions.

Overview

This action executes another action in the repetitive manner. Failure criteria for the step are the same as for a subflow step, since the action is actually translated into one.

Parameters

Name	Type	Description
step	mapping required	Action specification to be executed within the loop. Note: only type and name reserved fields can be used inside the step definition, but all action-specific arguments are allowed.
matrix	mapping required keys: string values: iterable	Loop variables definitions, e.g. i: !@ range(5). Multiple variables can be provided. If so, then the cartesian product of all specified ranges is used to produce the loop. Corresponding variables values are available in the locals namespace within the step. Note: eponymous local keys set from the locals directive of the loop step will be replaced.
strategy	string optional	Explicitly set strategy to be used within the loop subflow. When not set, base workflow value is used. Allowed values are listed on the corresponding page.
strict	boolean optional	Explicitly set dependency mode to be used within the loop subflow. When not set, base workflow value is used. See more about dependencies strictness here.

Outcomes injection

Basically the same as for the subflow action type.
