Reuse a role in different playbooks

[Alan Evangelista]

I current have one playbook for each application in my infrastructure: one for Gerrit, one for Jenkins, etc. Current filesystem structure:

playbooks
  |
  ---- gerrit
          |
          --- roles
                   |
                    ---- postfix
  ---- jenkins
          |
          --- master.yml
          --- roles
                   |
                    ---- postfix

My Jenkins master node setup playbook has something like:

- name: Setup Jenkins master node
  hosts: jenkins-master
  remote_user: root
  roles:
    - selinux
    - epel
    - packages
    - user
    - sudo
    - jenkins
    - nginx
    - systemd
    - firewalld
    - nfs
    - ssh
    - postfix

The gerrit setup playbook is similar.


- name: Setup Gerrit
  hosts: gerrit
  remote_user: root
  roles:
    - selinux
    - epel
    - packages
    - gerrit
    - systemd
    - firewalld
    - postfix

I'd like to reuse the postfix email server role used in Gerrit playbook in the Jenkins playbook. Currently, it is duplicated. Is that possible or should I use a different Ansible files organization to achieve the reuse I desire?

I'd put both those plays into site.yml , just targeting different host
groups, and have a single roles/ directory.

If you'd prefer, there's nothing wrong with a jenkins.yml and
gerrit.yml up in the same folder
as site.yml.
