Adding power user with ansible

create_user.yml

# 
# Simple playbook to create passwordless sudo user with pubkey authentication for future ansible use
# This assumes you know some other user login/pass
#
# Three simple steps:
# 1. Create some public key: ssh-keygen -t rsa -C "me@example.com"
# 2. Add some inventory into inventory file
# 3. Run playbook: ansible-playbook -i inventory create_user.yml -e "createuser=myuser pubkey_file=~/.ssh/my_pubkey.pub" -u someotheruser -k
