Question:
I have my directory structure as this
|
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 |
└── digitalocean ├── README.md ├── play.yml └── roles ├── bootstrap_server │ └── tasks │ └── main.yml ├── create_new_user │ └── tasks │ └── main.yml ├── update │ └── tasks │ └── main.yml └── vimserver ├── files │ └── vimrc_server └── tasks └── main.yml |
When I am creating a user under the role create_new_user, I was hard coding the user name as
|
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 |
--- - name: Creating a user named username on the specified web server. user: name: username state: present shell: /bin/bash groups: admin generate_ssh_key: yes ssh_key_bits: 2048 ssh_key_file: .ssh/id_rsa - name: Copy .ssh/id_rsa from host box to the remote box for user username become: true copy: src: ~/.ssh/id_rsa.pub dest: /home/usernmame/.ssh/authorized_keys mode: 0600 owner: username group: username |
One way of solving this may be to create a var/main.yml and put the username there. But I wanted something through which I can specify the username at play.yml level. As I am also using the username in the role vimrcserver.
I am calling the roles using play.yml

1 2 3 4 5 6 7 8 |
--- - hosts: testdroplets roles: - update - bootstrap_server - create_new_user - vimserver |
Would a template work here in this case? Couldn’t find much from these!
Answer:
I got it working by doing a
|
1 2 3 4 5 6 7 8 9 10 |
--- - hosts: testdroplets roles: - update - bootstrap_server - role: create_new_user username: username - role: vimserver username: username |
on play.yml
Although would love to see a different approach then this

I finally settled with a directory structure like
|
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 |
$ tree . ├── README.md ├── ansible.cfg ├── play.yml └── roles ├── bootstrap_server │ └── tasks │ └── main.yml ├── create_new_user │ ├── defaults │ │ └── main.yml │ └── tasks │ └── main.yml ├── update │ └── tasks │ └── main.yml └── vimserver ├── defaults │ └── main.yml ├── files │ └── vimrc_server └── tasks └── main.yml |
Where I am creating a defaults/main.yml file inside the roles where I need the usage of {{username}}
If someone is interested in the code,
