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

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.
