Collection Note

This module is part of the ansible.builtin collection. To install the collection, use:

ansible-galaxy collection install ansible.builtin
Added in version historical.

Synopsis

  • Combines two lists into one with each element being the product of the elements of the input lists.
  • Creates 'nested loops'. Looping over C(listA) and C(listB) is the same as looping over C(listA | product(listB)).

Parameters

Parameter Defaults / Choices Comments
_additional_lists
list
Additional list for the product.
_input
list
required
First list.
repeat
int
Default: 1
Number of times to repeat the product against itself.

Notes

Note

  • This is a passthrough to Python's C(itertools.product)

Examples

# product => [ [ 1, "a" ], [ 1, "b" ], [ 1, "c" ], [ 2, "a" ], [ 2, "b" ], [ 2, "c" ], [ 3, "a" ], [ 3, "b" ], [ 3, "c" ], [ 4, "a" ], [ 4, "b" ], [ 4, "c" ], [ 5, "a" ], [ 5, "b" ], [ 5, "c" ] ]
product:  "{{ [1,2,3,4,5] | product(['a', 'b', 'c']) }}"

# repeat_original => [ [ 1, 1 ], [ 1, 2 ], [ 2, 1 ], [ 2, 2 ] ]
repeat_original: "{{ [1,2] | product(repeat=2) }}"

# repeat_product => [ [ 1, "a", 1, "a" ], [ 1, "a", 1, "b" ], [ 1, "a", 2, "a" ], [ 1, "a", 2, "b" ], [ 1, "b", 1, "a" ], [ 1, "b", 1, "b" ], [ 1, "b", 2, "a" ], [ 1, "b", 2, "b" ], [ 2, "a", 1, "a" ], [ 2, "a", 1, "b" ], [ 2, "a", 2, "a" ], [ 2, "a", 2, "b" ], [ 2, "b", 1, "a" ], [ 2, "b", 1, "b" ], [ 2, "b", 2, "a" ], [ 2, "b", 2, "b" ] ]
repeat_product:  "{{ [1,2] | product(['a', 'b'], repeat=2) }}"

# domains => [ 'example.com', 'ansible.com', 'redhat.com' ]
domains: "{{ [ 'example', 'ansible', 'redhat'] | product(['com']) | map('join', '.') }}"
