Ansible Role: Secure SSH

Configure SSH to follow better security practices.

Requirements

SSH key logins.

By default, this role will prevent password logins in favor of ssh keys. Running the login-user role first will set this up for you. If you aren't going to use that role, you will want to either achieve a similar result by another means or override this role's behavior (by means of a mechanism not yet written).

Role Variables

This role sets sane OS-specific defaults and is not yet very configurable, so the variables are simple and few:

ssh_service: ssh

The name of the service that provides SSH on your OS. Typically, ssh for Debian family and sshd of RedHat family. These two will be detected by the role. Override this variable to support other OSes, if necessary. Better yet, submit a pull request to fix it proper.

ssh_config: "/etc/ssh/sshd_config"

Location of the system-wide (not per-user) SSH configuration file on your OS (see above).

Dependencies

None, per se, but see "Requirements" above.

Example Playbook

- name: secure SSH
  hosts: all
  become: true

  roles:
     - { role: secure-ssh }
