I am using a template to run a python script. This works fine.

> `
> 
> * * *
> 
> - hosts: ISE  
> connection: local  
> args:  
> tasks:
> - script: /usr/bin/python3 …/scripts/ise\_add.py  
> register: output
> - debug: var=output.stdout\_lines
> 
> `

Now I would like to pass 2 parameters to the python script (hostname and ipaddress), either harcoded or from any file or any variable.  
May I use the “extra variables” section of the template panel?  
Do I have to use Jinja2?

Thanks  
Regards,  
Gilles

Hello,

for passing parameters to the script please see the first example on  
[https://docs.ansible.com/ansible/latest/modules/script\_module.html#examples](https://docs.ansible.com/ansible/latest/modules/script_module.html#examples).  
If you want to pass those parameters from variables then yes you need  
to use Jinja2.

Thanks,  
Martin

Hi Martin,

Thanks for the example. I would like to avoid to hardcode the parameters to be able to reuse the template. The idea was more to use variables.

I will have a look at the jinja2 side.

I may come back later if I don’t find what I am looking for.

Thanks

Gilles
