kevinveenbirkenbachandClaude Opus 5.5 cb4d340de9 test(lint): demand a package-install nocheck on every role package_install
The batch lint cannot see the conditions an include or a role invocation puts
around a task file, so an install there could pass as unconditional and be
dropped onto every host. Every package_install task in a role now has to say
why it cannot ride the deploy-start batch; the 26 existing ones name their
reason (needed before update, repository first, task or include condition,
conditional role, removal, controller delegation).

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.

Cosmos

The diagram places Sudo in the Infinito.Nexus cosmos: the components it deploys (capabilities), the central services it consumes (dependencies), and its outward reach (federation and bridged external networks).

Solid 1:1 edges are fixed relationships; dashed 0..1 edges are conditional (enabled only in matching deployments); red 0..0 edges are turned off in this role. Node markers show the role's deploy modes (💻 host, 🐳 compose, 🐝 swarm); ❌ marks a service that is explicitly turned off, and ⚙️ an Ansible role dependency declared in meta/main.yml.

Purpose

The primary purpose of this role is to ensure that the target system has a reliable sudo configuration. By installing the sudo package and deploying a standard sudoers file, the role facilitates proper administrative access and minimizes potential security risks.

Features

  • Sudo Package Installation: Installs the sudo package if it is not already present.
  • Default Sudoers Configuration: Deploys a default sudoers file with best-practice settings.
  • Drop-in Inclusion: Ensures that configuration files from /etc/sudoers.d are included.
  • Security Focus: Provides commented guidelines to avoid common sudo misconfigurations.
