[newbie] connecting to remote hosts and adding packages

[Mario Giammarco]

Hello,

I am trying ansible because it seems it is very simple in usage.

I have the following use case: 

- several ubuntu an debian servers (all permit login to non root users)

- user and password is different in each server

- I need to install a deb sources.list parametrized deb http://xxxxxxx/yyyyyy/ $(lsb_release -cs) main

It seems to me that this use case is very simple but I am confused:

1) I cannot find an easy way to manage the passwordless sudo use case

2) I cannot find how to parametrize sources.list

Thanks in advance for any suggestion!

Mario

True. At least if you compare against the right thing...

I would do the following:

Set up ansible vault so you can store variables in encrypted files (I
have a file that holds my vault-password, but you can also get
prompted for it if you prefer)

Put user and password for the host foobar in
host_vars/foobar/encrypted.yml via "ansible-vault create ...":

--- snip ---
---
ansible_user: your_username
ansible_become_pass: very_secret_password
--- snip ---

Repeat for each of your hosts.

Use a playbook that is run as non-root and uses sudo:
--- snip ---
- hosts: whatever
become: true
become_method: sudo

tasks:
...
--- snip ---

Template it:
https://docs.ansible.com/template_module.html

I would guess some variable like ansible_distribution could match
whatever "$(lsb_release -cs)" spits out...
