Ansible Dynamic node tasks

Looping over Parallel Sets of Data

Suppose you have the following variable data was loaded in via somewhere:

alpha: [ 'a', 'b', 'c', 'd' ] numbers: [ 1, 2, 3, 4 ] And you want the set of ‘(a, 1)’ and ‘(b, 2)’ and so on. Use ‘with_together’ to get this:

tasks: - debug: msg="{{ item.0 }} and {{ item.1 }}" with_together: - "{{alpha}}" - "{{numbers}}"

We can use the above loop to fulfill our requirement where to create/use multiple nodes in respective of LB or where to use multiple items.
