sys-service

Description

Role to manage systemd service units for Infinito.Nexus software stacks. It installs or removes unit files, configures runtime behavior, and ensures services are properly deployed.

Overview

  • Resets service units by removing old or obsolete definitions.

  • Deploys new service unit files and service scripts.

  • Optionally sets up timers linked to the services.

  • Ensures correct reload/restart behavior across the stack.

  • Provides the shared files/debug.sh SPOT for reusable service-failure diagnostics.

  • Exposes tasks/utils/debug.yml as the canonical Ansible wrapper around that script.

Cosmos

The diagram places sys-service 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.

Features

  • Unit Cleanup: Automated removal of old service units.

  • Custom Templates: Supports both systemctl.service.j2 and systemctl@.service.j2.

  • Timers: Integrates with sys-timer for scheduled execution.

  • Runtime Limits: Configurable RuntimeMaxSec per service.

  • Handlers: Automatic reload/restart of services when definitions change.

  • Shared Diagnostics: Centralized systemctl/journalctl/unit-file diagnostics via files/debug.sh.

  • Wrapper Task: Reusable Ansible include in tasks/utils/debug.yml for calling and printing the shared diagnostics.
