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>

# 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](https://s.infinito.nexus/code), maintained and developed by [Kevin Veen-Birkenbach](https://www.veen.world/).
|
|
|
|
## 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).

subgraph role [sys-svc-container 💻]
|
|
svc_svc_container["svc-container"]
|
|
svc_busybox["busybox"]
|
|
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.
