Package update

Description

Operating-system package managers such as apt, pacman and dnf keep installed software in sync with their upstream distribution repositories. Each one ships with a different command surface but they all serve the same goal: refresh the index and upgrade every installed package on the host.

Overview

This role refreshes the package index and upgrades every installed package on the host. tasks/main.yml reads ansible_facts['distribution'] and dispatches to one of three task files grouped by package-manager family. Debian and Ubuntu both use apt, Fedora and CentOS both use dnf, so each pair shares a single task file. A separate unsupported.yml fails loudly with a clear message when a host runs a distribution that this role does not yet cover.

`ansible_facts['distribution']`	Task file	Module
`Archlinux`	`arch.yml`	`community.general.pacman`
`Debian` / `Ubuntu`	`debian.yml`	`ansible.builtin.apt`
`Fedora` / `CentOS`	`fedora.yml`	`ansible.builtin.dnf`
anything else	`unsupported.yml`	`ansible.builtin.fail`

Cosmos

The diagram places Package update 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

Per-family dispatch: Routes by ansible_facts['distribution'] so the caller never has to gate the role with a when: clause.
Five-distro coverage: Supports the five default CI distros (Archlinux, Debian, Ubuntu, Fedora, CentOS) without duplicated task code.
Loud on unsupported hosts: Fails with a clear message instead of silently skipping when the host runs an unmapped distribution.
Once-per-play idempotency: Wraps the dispatch in when: run_once_update is not defined and writes the flag via tasks/utils/once/flag.yml, so repeated invocations within one play are no-ops.

Quick Setup

Development

Clone, set up the workstation, and deploy Package update onto the local stack:

git clone https://github.com/infinito-nexus/core.git
cd core
make onboard
make compose-deploy mode=reinstall apps=update full_cycle=false

Production

Install Package update directly onto the target machine: clone the repository, install the OS prerequisites and the repository toolchain, then deploy against localhost over a local connection (no SSH, no container):

git clone https://github.com/infinito-nexus/core.git
cd core
bash scripts/install/package.sh
make install
source scripts/meta/env/load.sh

APP=update
DOMAIN=<your-domain>
TLS_MODE=self_signed
SSH_PUBLIC_KEY="<your-ssh-public-key>"
INVENTORY=inventories/production
infinito administration inventory provision "$INVENTORY" \
  --inventory-file "$INVENTORY/devices.yml" \
  --host localhost \
  --include "$APP" \
  --vars "{\"TLS_MODE\": \"$TLS_MODE\", \"DOMAIN_PRIMARY\": \"$DOMAIN\", \"users\": {\"administrator\": {\"authorized_keys\": [\"$SSH_PUBLIC_KEY\"]}}}"
infinito administration deploy dedicated "$INVENTORY/devices.yml" \
  --password-file "$INVENTORY/.password" \
  --diff -vv

Developer Notes

To extend support for a new distribution, add the distribution name to the lookup dict in main.yml. When the new distribution shares a package manager with an existing entry, point it at that entry's task file. When it brings a new package manager, add a new family file under tasks/ and keep meta/main.yml platforms in sync.
