personalised.yaml is a basic ansible playbook to personalise the
servers I work with, used with ansible 2.5.3.

ssh-agent should be running, host_vars should be set with
ansible-vault, e.g.:

  ansible-vault create host_vars/example.com.yaml

With contents such as:

  ansible_become_password: examplepassword

Invoked with:

  ansible-playbook --ask-vault-pass ~/.ansible/personalised.yml
