Ansible provides a number of loops in the playbook, such as standard loops, looping over files, subelements, do-until, and many more. In this section, we will look at two of the most commonly used loop forms: standard loops and looping over hash values.
Standard loops in playbooks are often used to easily perform similar tasks multiple times. The syntax for standard loops is very easy: the {{ item }} variable is the placeholder looping over the with_items list. For example, take a look at the following section in the chapter8_4.yml playbook:
tasks:
- name: echo loop items
command: echo {{ item }}
with_items: ['r1', 'r2', 'r3', 'r4', 'r5'] It will loop over the five list items with the same echo command:
