Most of the default distro images disallow root ssh connections, as a potential security measure. This Ansible role reverts back the changes in cloud-init configuration, same as the changes in root's authorized_keys file.
Btw, if you hate the error messages:
Please login as the user "centos" rather than the user "root".
Please login as the user "fedora" rather than the user "root"
Please login as the user "cloud-user" rather than the user "root".
Then you'll probably love this role.
Basic wrapper playbook (default remote_user == 'root'):
- hosts: all
gather_facts: False
roles:
- role: ansible-fix-ssh-root
Have a look at ./example directory.
