The cosmos generator linked a consumer to its provider only through an '<role>' in group_names reference or an explicit provides: name. A hard dependency has neither -- pinning the provider on unconditionally is exactly what removes the Jinja reference the generator was reading -- so web-svc-asset's bond to web-svc-file vanished from the diagram the moment it became binding. Match a service key against the provider's own primary key from the registry, in both directions. Services the role turns off drew a solid 1:1 edge, claiming a mandatory relationship for something that carries nothing at deploy time. They now render as a red 0..0 edge; edge merging gained a real precedence so a provider consumed through two keys stays live when only one is off. Named colour, not hex: a '#' opens an entity code in the mermaid lexer and turns the whole diagram into a parse error on GitHub. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>

# Administrator User
|
||
|
||
## Description
|
||
|
||
This role creates a dedicated administrator user for local administrative tasks. The administrator account is configured to require a password when executing [sudo](https://en.wikipedia.org/wiki/Sudo), ensuring secure privilege escalation. For security reasons, it is recommended to use this dedicated administrator user instead of the default root account.
|
||
|
||
SSH key management follows a **single point of truth**: keys must be provided via `lookup('users', 'administrator').authorized_keys` (**must contain at least one SSH public key**), and are deployed to the administrator’s `authorized_keys` file.
|
||
|
||
## Overview
|
||
|
||
Optimized for secure system management, this role performs the following:
|
||
|
||
- Creates an administrator user with a home directory.
|
||
- Configures proper permissions for the administrator’s home directory and associated scripts.
|
||
- Deploys SSH `authorized_keys` from `lookup('users', 'administrator').authorized_keys`, leveraging [SSH](https://en.wikipedia.org/wiki/Secure_Shell) best practices.
|
||
- Grants [sudo](https://en.wikipedia.org/wiki/Sudo) privileges to the administrator user with password authentication using a dedicated sudoers file.
|
||
|
||
## Cosmos
|
||
|
||
The diagram places Administrator User 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 provide a secure and dedicated administrator account solely for running local administration tasks. This approach minimizes security risks associated with using the root account and enforces best practices in user privilege management.
|
||
|
||
Requiring at least one SSH public key ensures that the administrator account is always accessible via secure, key-based authentication and avoids insecure or unusable configurations.
|
||
|
||
## Features
|
||
|
||
- **User Creation:** Establishes an administrator user with a home directory and generated SSH keys.
|
||
- **Home Directory Configuration:** Sets secure permissions on the administrator’s home directory and script folder.
|
||
- **SSH Authorized Keys:** Deploys keys from `lookup('users', 'administrator').authorized_keys` (**SPOT-only, must contain at least one key**).
|
||
- **Sudo Privileges:** Deploys a dedicated sudoers configuration to grant the administrator user [sudo](https://en.wikipedia.org/wiki/Sudo) rights with password prompt.
|
||
- **Modular Integration:** Integrates with common routines and roles to further enhance system security.
