Hi everybody,
I hope this the good place to post my problem.

I have declared this inventory in yml

all:
children:
server_country_prod:
hosts:
server1.com:
vars:
…

server_country_preprod:
hosts:
server2.com:
vars:
…

vars:

ansible_ssh_user: user
ansible_user: user
ansible_connection: ssh
ssh_args: -o ForwardAgent=yes

If I write that

  • hosts: “{{ groups[‘server_country_prod’][0] }}”
    #gather_facts: no
    become: yes
    I can lauch my playbook easily

But if I want lauching my playbook with extra var

ansible-playbook -i inventory.yml -e var1=server -e var2=country tasks/main.yml

I can’t lauch my playbook what I have writing

  • hosts: " groups[‘{{var1}}_{{var2}}_prod’][0] "

I have the following error:
PLAY [groups[‘server_country_prod’][0]] ****************************************************************************************************************************************************************************
skipping: no hosts matched

Somebody can help me to understand why?
Thanks for your read and your help.
Best regards

Hi everybody,

I have declared this inventory in yml
all:
children:
server_country_prod:
hosts:
server1.com <http://server1.com/&gt;:

server_country_preprod:

....
vars:
ansible_ssh_user: user
ansible_user: user
ansible_connection: ssh
ssh_args: -o ForwardAgent=yes

If I write that
- hosts: "{{ groups['server_country_prod'][0] }}"
#gather_facts: no
become: yes
I can lauch my playbook easily

But if I want lauching my playbook with extra var
ansible-playbook -i inventory.yml -e var1=server -e var2=country tasks/main.yml

I can't lauch my playbook what I have writing
- hosts: " groups['{{var1}}_{{var2}}_prod'][0] "

groups is not inside {{ ... }}, so it isn't evaluated at all. Also you cannot
nest the curly braces.

Try "{{ groups[ var1 + '_' var2 + '_prod' ][0] }}" (untested).
