Hi,

I am a beginner with ansible; I couldn’t find the answer yet.
I want to bootstrap virgin raspberry pi’s (raspbian based);

It all works fine as intended, except for one step,
I have to change the ansible hosts file manually half way between two playbooks to make it work.

What I want to fully automated:

  1. Start with pi:raspberry account
  2. Add a new admin account & add admin’s public key to authorized hosts file
  3. Change default password of “pi”
  4. Some other stuff, install a few packages
  5. reboot
  6. Continue configuration via admin account & public key authentication

Question: how can I change midway in a playbook from username:password to public key (with admin account?)
or…I am fine to split in 2 playbooks, how can I have one playbook with pi:raspberry username/password
(as it is configured in hosts) and 2nd playbook with with admin:

hosts
…
…
[pi:vars]
ansible_connection=ssh

Disable below after new admin account with public key is created

ansible_user=pi
ansible_ssh_pass=raspberry

I suppose you can set these variables through a set_fact task, e.g.

set_fact:
  ansible_user: admin

Please note that these changes only apply to the current play.
