how to loop inventory groups in ansible

[Chetan Kumar Sriram]

Hi I am struck with looping for below requirement.

The mail section has to loop over first group in inventory, check the uptime with the condition of more than 200 days and send mail to only the lab_email with lab servers only

Next go to 2nd web group check condition and send mail to web_email with web servers only.

  - name: send mail
    hosts: all
    gather_facts: no
    become: yes
    tasks:
       - name: check uptime
         ignore_errors: yes
         shell: uptime |awk '{print $3}'
         register: up_time
       - debug:
           msg: "{{inventory_hostname}} has {{ up_time.stdout }} days uptime"
       - name: send mail to chetan
         mail:
           host: relay.services
           port: 25
           from: ad...@company.com
           to:  "{{web_email}}"
           subject: uptime
           body: |-
             {% for server, servervars in hostvars.items()  %}
             {% if servervars.up_time.stdout | default (0) |int >= 5 %}
                {{ server }} - {{"has"}} {{ servervars.up_time.stdout }} {{"days uptime. Consider rebooting for better performance"}}
             {% endif %}
             {% endfor %}
         become: no
         delegate_to: localhost
         run_once: true


INVENTORY FILE

[lab:vars]
lab_email="<labg...@company.com>"
[lab]
linuxlab-01
linuxlab-02

[web:vars]
web_email="<webg...@company.com>"
[web]
webserver-01
webserver-02

[db:vars]
db_email="<dbg...@company.com>"
dbserver-03
dbserver-04

You can modify the mail task to send per group:

- name: send mail to chetan
mail:
host: relay.services
port: 25
from: ad...@company.com
to: "{{web_email}}"

subject: uptime for {{item}}
body: |-
{% for server in group_names[item] %}
{% if hostvars[server]['up_time.stdout'] | default (0)

|int >= 5 %}
{{ server }} - {{"has"}}

{{hostvars[server]['up_time.stdout'] }} {{"days uptime. Consider

rebooting for better performance"}}
{% endif %}
{% endfor %}
become: no

loop: ['lab', 'web', 'db']
delegate_to: localhost
run_once: true

Another way, in you existing play change:

hosts: '{{target|default("all")}}'

And create new play:
inorder.yml

- import_playbook: send_mail.yml
vars:
target: lab

- import_playbook: send_mail.yml
vars:
target: web

- import_playbook: send_mail.yml
vars:
target: db
