A simple framework for running commands in parallel using templated commands and dictionaries of arguments.

# Look to see if the host is running WebLogic T3
template = "nmap -oG - -p {port} --script weblogic-t3-info {addr}"
items = [{"addr":"1.2.3.4","port": "7002"}]
my_tasks = []
for i in items:
    kwargs = items
    my_tasks.append(
        Task(
            command=template,
            kwargs=kwargs,
            target_metadata={"uuid": "fedcba09-1234-1111-bcde-1234567890fe"},
            # This is in the output if, and only if, T3 is running
            output_filter="T3",
        )
    )

tr = TaskRunner(tasks=my_tasks)
tr.run()
