Implementing DevOps with Ansible 2

Iterating over register contents

Finally, the contents of the register can be iterated over to create new things and adapt existing system solutions. This type of implementation might be something like creating a list of directories, touching a set of files, or creating a list of users. Basically, it means we can use the contents of the register as a list. Let's take a look at a quick example provided by https://www.Ansible.com/:

--- name: registered variable usage as a with_items list  hosts: all  tasks:      - name: retrieve the list of home directories        command: ls /home        register: home_dirs      - name: add home dirs to the backup spooler        file: path=/mnt/bkspool/{{ item }} src=/home/{{ item }} state=link        with_items: "{{ home_dirs.stdout_lines }}
