sequence – generate a list based on a number sequence¶
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 rangefilter as an alternative.
Parameters¶
Examples¶
- name: create some test users
  user:
    name: "{{ item }}"
    state: present
    groups: "evens"
  with_sequence: start=0 end=32 format=testuser%02x
- 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
  group:
    name: "group{{ item }}"
    state: present
  with_sequence: count=4
- name: the final countdown
  debug: msg={{item}} seconds to detonation
  with_sequence: end=0 start=10

Hint
Configuration entries for each entry type have a low to high priority order. For example, a variable that is lower in the list will override a variable that is higher up.
