Implementing DevOps with Ansible 2

Iterating over sequential numbers

Counting through a sequential number set is a fundamental programming concept. It involves essentially creating a counter that counts forward or backward sequentially by a given step. That is to say, we can count up or down from a given number using Ansible sequential numerical iterators. We can then pipe the numerical data from Ansible into, say, a shell call or a debug message. Let's take a quick look at a brief example:

# Ansible Example provided by Ansible.com# create some test users - user:     name: "{{ item }}"     state: present     groups: "evens"   with_sequence: start=0 end=32 format=testuser%02x
