According to the Mistral Workflow Language (v2) documentation1, which is one of the technologies that can be used in a NSP workflow2, with-items is a task property that allows the action associated with a task to be run multiple times over a list of items1. The syntax for using with-items is:

task_name:

action:<action_name>

input:

<input_name>:<%item()%>

with-items:itemin<list>

You need to replace <action_name>, <input_name>, and <list> with your desired values. You can also use other properties such as concurrency, retry, or count to control how many iterations are executed in parallel, how many times an iteration is retried if it fails, or how many times an iteration is executed respectively1.

This attribute specifies a manual approval step before executing a task1. The other attributes will either delay or abort the execution of a task, but not halt the entire workflow.

the input that is optional when using the std.ssh action is cmd. This parameter specifies the command to be executed on the remote server1. If this parameter is not provided, the action will only establish an SSH connection with the remote server and return its output1. The other parameters are required to authenticate and connect to the remote server.

This syntax assumes that there is a previous task that returns an object with an attribute named rtt that contains the round-trip time value1. The expression <% task().result.rtt %> evaluates to this value and assigns it to the variable rtt in the workflow context1.

a workflow can use environments to make it portable if the workflow needs to be executed on either a development or production lab. Environments are files that contain key-value pairs that can be used as input parameters for workflows1. Environments allow workflows to be executed with different settings without modifying the workflow definition1.
