ANSIBLE: using variables on a hosts file (ssh)

Question

I´m newbie with this fantastic automation engine, and have a little issue with the vars file:

By the momment, I must connect via SSH without keypars using an specifics users and password.

hosts file

[all:vars]
connection_mode1=ssh 
ssh_user1=user1
ssh_pass1=pass1

[serverstest]
host1 ansible_connection=connection_mode1 ansible_ssh_user=ssh_user1 ansible_ssh_pass=ssh_pass1

I'm also trying wrap with "" and {} but doesn't works.

How can I use variables on this parameters?

why not just define ansible_connection and other params in [all:vars]? — Konstantin Suvorov

ansible_ssh_user has been deprecated since v. 2.0. It becomes ansible_user. See here.

Never store ansible_ssh_pass variable in plain text; always use a vault. See Variables and Vaults.

Anyway, having a mytest.inventory file as follows

[all:vars]
ssh_user1=user1

[serverstest]
host1 ansible_user="{{ ssh_user1 }}"

it works, e.g.

ansible -i mytest.inventory serverstest -m ping -k

Option -k asks for the password.

If you still want to write the password in the inventory you can leave the password variable definition and add ansible_ssh_pass="{{ ssh_pass1 }}"

[serverstest]
192.168.15.201 ansible_user="{{ ssh_user1 }}" ansible_ssh_pass="{{ ssh_pass1 }}"

thank you! I´m only testing the possibilities in a lab´environment to implement this solutions. By the momment, the security has not a high priority but your appointment is gratefully accepted :) Im test the following

[all:vars]   ssh_user1=user   ssh_pass1=password   [serverstest]   machine1 ansible_ssh_user="{{ ssh_user1 }}" ansible_ssh_pass="{{ ssh_pass1 }}"   machine2 ansible_user="{{ ssh_user1 }}" ansible_ssh_pass="{{ ssh_pass1 }}"

Right comment: Im test the following

[all:vars]      ssh_user1=user     ssh_pass1=password     [serverstest]     machine1 ansible_ssh_user="{{ ssh_user1 }}" ansible_ssh_pass="{{ ssh_pass1 }}"     machine2 ansible_user="{{ ssh_user1 }}" ansible_ssh_pass="{{ ssh_pass1 }}"

the machine 2 (without "ssh" in the user) not works. But it doesn´t matter Thank you so much for your feedback

May be it depends from the Ansible version. If it is less than 2.0 anslibe_ssh_user is right.
