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).

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.
