[ansible-project] Would like to update root passwords using user module, but have a different passwords for each VM and read those from a csv file

[Tibor I]

Hi Ansible gurus,

I have a csv file with a list of hostnames and passwords

eg: 
host1,password1
host2,password2

I can successfully read from that file using the read_csv module.

Now I'd like to use the "user" module to update the root password on each 
host defined in the CSV file. So I've got:

- name: Bulk root password updater
  hosts: {{ groups.infrastructure }}
  become: yes
  gather_facts: False
  tasks:
    - read_csv:
        path: ./passtest.csv
        fieldnames: hostname,password
        delimiter: ','
      delegate_to: localhost
      register: destpasswords


  - debug:
        var: destpasswords.list.0.hostname
        var: destpasswords.list.0.password
            #  msg: '{{destpasswords.list.0.value}}'

#Works up to this point, the debug above prints the first value from the 
file and correctly puts it into a variable. So now I want to use the user 
module to actually update the root passwords to whatever it reads from the 
file:

  - name: Update root password to match what's in CSV file
      user:
      name: root
      update_password: always
      password: "{{ destpasswords.list.hostname.password | 
password_hash('sha512') }}"
    loop: "{{destpasswords.list}}"
    loop_control:
       loop_var: hostname


However that doesn't work. I've been able to update multiple hosts to the 
same root password(which is not what I want). 

Any help much appreciated. I can do it a different way(ie. yaml instead of 
csv) if that's easier.
