Synopsis

• generates a sequence of items. You can specify a start value, an end value, an optional “stride” value that specifies the number of steps to increment the sequence, and an optional printf-style format string.
• Arguments can be specified as key=value pair strings or as a shortcut form of the arguments string is also accepted: [start-]end[/stride][:format].
• Numerical values can be specified in decimal, hexadecimal (0x3f8) or octal (0600).
• Starting at version 1.9.2, negative strides are allowed.
• Generated items are strings. Use Jinja2 filters to convert items to preferred type, e.g. {{ 1 + item|int }}.
• See also Jinja2 range filter as an alternative.

Examples

- name: create some test users

- name: create a series of directories with even numbers for some reason
  file:
    dest: "/var/stuff/{{ item }}"
    state: directory
  with_sequence: start=4 end=16 stride=2

- name: a simpler way to use the sequence plugin create 4 groups

    name: "group{{ item }}"
    state: present
  with_sequence: count=4

- name: the final countdown
