Il se peut que l'imprimante ne soit pas reconnue dans l'interface de Cups (imprimantes locales). Ceci est dû au fait que le noyau cré un composant qui se trouve dans /dev/usb/lp0. Une règles udev résout ce problème et permet de faire un lien symbolique /dev/lp0 → /dev/usb/lp0.

Ansible inventory script - inventaire dynamique 1

Voir :

Voir aussi :

In Ansible 2.10 and later, inventory scripts moved to their associated collections. Many are now in the ansible-community/contrib-scripts repository. We recommend you use Inventory plugins instead.

Source : https://docs.ansible.com/ansible/latest/inventory_guide/intro_dynamic_inventory.html#intro-dynamic-inventory

Nous allons coder un inventory script en bash en mode “hello world”

Voici le script bash avec des données codés en dures dedans, c'est moche mais c'est juste pour un PoC.

inv.sh

#! /bin/bash
 
set -euo pipefail

srv-db2 db=2
 
[plop]
test-ansible
EOF
}
 
arg_list() {
        mk_ini_tmp_inv
        ansible-inventory -i "$TMP_INV_INI" --list
}
 
arg_host() {
        mk_ini_tmp_inv
        ansible-inventory -i "$TMP_INV_INI" --host "$1"
}
 
usage() {
        ansible-doc -t inventory script
}
 
while [ "${1-}" != "" ]; do
    case $1 in
        --list )                        shift
                                        arg_list
                                ;;
        --host )                        shift
                                        arg_host "$1"
                                ;;
        -h | --help )                   usage
                                        exit 0
                                ;;

                                        shift
                                        break
                                ;;
        -*)                             echo "SCRIPT_NAME: invalid option" >&2
                                        echo "Try '$SCRIPT_NAME --help' for more information." >&2
                                        exit 1
                                ;;
        *)
                                        usage
                                ;;
    esac
    shift
done

Rendons le script exécutable

chmod +x inv.sh

Nous testons la sortie de notre script bash

./inv.sh --list

{
    "_meta": {
        "hostvars": {
            "srv-db1": {
                "db": 1,
                "os": "linux"
            },
            "srv-db2": {
                "db": 2,
                "os": "linux"
            },
            "srv-web1": {
                "os": "linux",
                "web": 1
            },
            "srv-web2": {
                "os": "linux",
                "web": 2
            },
            "test-ansible": {
                "os": "linux"
            }
        }
    },
    "all": {
        "children": [
            "db",
            "plop",
            "ungrouped",
            "web"
        ]
    },
    "db": {
        "hosts": [
            "srv-db1",
            "srv-db2"
        ]
    },
    "plop": {
        "hosts": [
            "test-ansible"
        ]
    },
    "web": {
        "hosts": [
            "srv-web1",
            "srv-web2"
        ]
    }
}

Nous testons de nouveau la sortie de notre script mais pour un host spécifique cette fois

./inv.sh --host srv-web1

{
    "os": "linux",
    "web": 1
}

A présent testons avec Ansible :

$ ansible -i inv.sh -m ping plop
[WARNING]:  * Failed to parse /home/jean/tmp/inv.sh with script plugin: Inventory script (/home/jean/tmp/inv.sh) had an execution error:
[WARNING]:  * Failed to parse /home/jean/tmp/inv.sh with ini plugin: /home/jean/tmp/inv.sh:3: Expected key=value host variable assignment, got: -euo
[WARNING]: Unable to parse /home/jean/tmp/inv.sh as an inventory source
[WARNING]: No inventory was parsed, only implicit localhost is available
[WARNING]: provided hosts list is empty, only localhost is available. Note that the implicit localhost does not match 'all'
[WARNING]: Could not match supplied host pattern, ignoring: plop

Ça ne marche pas. Ansible s'attend à trouver un inventaire au format ini et à la place il a du bash.

Les inventory script doivent être en Python. J'ai essayé de renommer ce script inv.sh en inv.py mais ça ne marche pas.

Nous allons coder un wrapper Python qui lance notre script bash.

inv.py

#! /usr/bin/env python3
 
import os
import argparse
 
parser = argparse.ArgumentParser()
parser.add_argument('--list', action='store_true')
parser.add_argument('--host')
 
args = parser.parse_args()
 
if args.list:
    os.system('bash ./inv.sh --list')
elif args.host:
    os.system(f'bash ./inv.sh --host {args.host}')

Rendons ce script Python exécutable

chmod +x inv.py

Et ça marche :

$ ansible -i inv.py -m ping plop
test-ansible | SUCCESS => {
    "ansible_facts": {
        "discovered_interpreter_python": "/usr/libexec/platform-python"
    },
    "changed": false,
    "ping": "pong"
}
