vars_prompt in Ansible

[Stepan Harutyunyan]

Hi All,

I want to create Ansible script which will create user on linux servers, so I use vars_propt for entering values of username, groupname, shell. For groupname variable I want to use username's value as a default value, but when I wrote default: {{username}} in my script I got syntax error, (I tried to write default: "{{username}}" , default: '{{username}}' but in this cases script doesn't understand that this is variable.

- hosts: servers

  vars_prompt:

    - name: "username"

      prompt: "Enter new username"

      private: no

    - name: "groupname"

      prompt: "Please enter group name for user"

      private: no

      default: {{username}}

    - name: "usershell"

      prompt: "Please enter shell name for user"

      private: no

      default: "/bin/bash"

Hi,

I'm not getting a syntax error with

default: "{{ username }}"

It works (the default value is assigned if no input),
but the default value is not templated in the prompt.
This is printed instead:

Please enter group name for user: [{{ username }}]:

I believe it's related to this issue:

Cheers,
Marko

Hi Marko,

When script printed "Please enter group name for user: [{{ username
}}]:" I thought that it understood {{ username }} as a string, but after
your reply I tried to debug groupname value it works thank you, but now
I have other issue I want to use {{ username }} in my group's prompt
msg, when I wrote:

- name: "groupname"
prompt: "Please enter group name for user {{ username }}"
private: no
default: "{{ username }}"

msg of promt is:

Please enter group name for user {{ username }} [{{ username }}]:

I want to see typed user name instead of {{ username }}

You don't have hostvars available at that point, you can use extra_vars though.

If you want to default to the user currently running Ansible, you can do this:

default: "{{lookup('env', 'USER')}}"
