How do I assign different variable values for different group system

[Xinhuan Zheng]

Hello,

I'm trying to create an Ansible role, networking, to automate /etc/resolv.conf file. I created this role like below:

production

networking.yml

group_vars/

  agroup

  bgroup

roles/

  networking/

    tasks/main.yml

    templates/resolv.conf.j2

In my resolv.conf.j2 file, I put variables in this file:

{% for item in nameserver %}
nameserver {{ item }}
{% endfor %}

The name servers will be different for different group systems.

In group_vars/agroup:

---

nameservers:

  - 192.168.10.251

  - 192.168.10.252

In group_vars/bgroup:

---

nameservers:

  - 192.168.101.251

  - 192.168.101.252

In playbook networking.yml:

---

- hosts: all

  roles:

    - networking

In production (inventory) file:

[agroup]

myserver

[bgroup]

myserver2

Here is command I want to use for play:

$ ansible-playbook -i production networking.yml -l myserver

$ ansible-playbook -i production  networking.yml -l myserver2

Does above play use agroup defined nameservers for myserver, and bgroup defined nameservers for myserver2?

Thank you,

- Xinhuan

Why don't you just run the code and check for yourself?
Anyway, the answer to your question is yes.
