kevinveenbirkenbachandClaude Opus 5 c55f508e05 feat(readme): draw mandatory and disabled service relations
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.

Docker Server

Description

This role installs and maintains the Docker service, including Docker Compose, on Linux systems.
It is part of the Infinito.Nexus Project, maintained and developed by Kevin Veen-Birkenbach.

Overview

The role ensures that Docker and Docker Compose are present, integrates essential backup, repair, and health check roles, and supports cleanup or full reset modes for a fresh Docker environment.
When enabled via MODE_CLEANUP or MODE_RESET, it will automatically prune unused Docker resources.
MODE_RESET additionally restarts the Docker service after cleanup.

Cosmos

The diagram places Docker Server 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).

        svc_node["node"]
    end

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.

Features

  • Automated Installation
    Installs Docker and Docker Compose via the system package manager.

  • Integrated Dependencies
    Includes backup, repair, and health check sub-roles

  • Cleanup & Reset Modes

    • MODE_CLEANUP: Removes unused Docker containers, networks, images, and volumes.
    • MODE_RESET: Performs cleanup and restarts the Docker service.
  • Handler Integration
    Restart handler ensures the Docker daemon is reloaded when necessary.
