Basically username has the hostname as a variable.

% O3 V" \0 @% N; i8 TNow our inventory has just IPs with group web.

9 ]$ O9 {1 m. ]& ^172.16.2.8
172.16.x.y
172.16.y.z
My playbook yml has ansible user as following.

> cat uptime.yml
- hosts: host
  vars:
    ansible_ssh_port: xxxx
    ansible_user: bob~1234~{{inventory_hostname}}

However, when I use following ansible-playbook command, it gives error for incorrect username.
