Environment presets

[chavezdf]

Questions:
-It is important to know how control node and remote nodes are preset.
-All remote nodes should have the same root password? All these commands will been executed by root on remote hosts, because automation user has not been created yet. Does root user on remote nodes should be configured passwordless?
-Why you use sudo instead of using -u root -k?
-First you should add the inventory hosts in known_hosts, because always request validation, unless you deactivate this first. Did you?

sudo ansible all -m user -a "name=automation password={{ 'devops' | password_hash('sha512', 'salt')}}"
sudo ansible all -m authorized_key -a "key={{ lookup('file', '/home/automation/.ssh/id_rsa.pub') }} user=automation"
sudo ansible all -m copy -a 'content="automation ALL=(ALL) NOPASSWD:ALL" dest=/etc/sudoers.d/automation'
