Sudo¶

Description¶

This role installs the sudo package and deploys a default sudoers file to ensure secure and consistent privilege escalation on the target system. It uses a preconfigured sudoers file that follows best practices and includes directives to read drop-in files from /etc/sudoers.d.

Overview¶

Optimized for security and ease of administration, this role guarantees that sudo is installed and configured according to recommended practices. The provided sudoers file includes essential comments, host/user aliases, and defaults to help prevent misconfigurations.
