Score: 50</p>
<p>Au programme de cette année : lautomatisation ! Il existe plusieurs outils connus pour ça, vous en avez sans aucun doute entendu parler si vous êtes adminsys : <a href="https://puppet.com">Puppet</a>, <a href="https://www.chef.io/chef/">Chef</a>, <a href="https://saltstack.com/">Salt</a> et le petit dernier : <a href="https://www.ansible.com/">Ansible</a>.</p>
<p>Ansible a la réputation dêtre le plus “accessible” avec une courbe dapprentissage assez basse. Il peut être pertinent de lutiliser à partir dun seul serveur pour faciliter des déploiements selon les besoins (configuration des outils basique, serveur web, BDD…).</p>
<p>Au contraire des trois autres, il nutilise pas dagents (<em><a href="https://www.ansible.com/benefits-of-agentless-architecture">agentless</a></em>), cest à dire que rien na besoin de tourner côté serveur pour le faire fonctionner, ce qui le rend <em>de facto</em> plus facile à mettre en place. <strong>Il requiert seulement un accès SSH et python sur les serveur</strong>.</p>
<p>Toujours concernant Ansible (bien entendu), on parle souvent d<strong><a href="https://fr.wikipedia.org/wiki/Idempotence">idempotence</a></strong>, ce qui signifie quune opération a le même effet quon lapplique une ou plusieurs fois.</p>
<p>Les recettes utilisent du <a href="https://docs.ansible.com/ansible/YAMLSyntax.html">YAML</a> et <a href="https://docs.ansible.com/ansible/playbooks_filters.html">Jinja2</a> pour les templates. Lutilisation de YAML permet davoir des recettes normalement facile à lire et à comprendre. À noter aussi que grâce au (ou à cause du) YAML, lindentation est primordiale et source de bug si elle nest pas respecté comme on le verra plus tard.</p>
<p>Au programme aujourdhui :</p>
<ul>
<li>installation dAnsible (<strong>v2.2.0.0</strong>)</li>
<li>tests de connexions aux serveurs</li>
<li>installation de quelques paquets</li>
<li>debug et tests</li>
</ul>
<h2 id="installation">Installation</h2>
<p>Si vous avez besoin dautre chose, ça devrait être dans <a href="https://docs.ansible.com/ansible/intro_installation.html">la documentation</a>.</p>
<h3 id="sur-debian">sur <a href="https://docs.ansible.com/ansible/intro_installation.html#latest-releases-via-apt-debian">Debian</a></h3>
<p>Vous pouvez linstaller directement via les dépôts, mais ce sont évidemment des versions anciennes (cf. <a href="https://packages.debian.org/search?keywords=ansible">packages.debian.org</a>), pour avoir une version plus récente, ajouter la ligne suivante à <code class="language-plaintext highlighter-rouge">/etc/apt/sources.list.d/ansible.list</code> :</p>
<div class="language-plaintext highlighter-rouge"><div class="highlight"><pre class="highlight"><code>deb http://ppa.launchpad.net/ansible/ansible/ubuntu trusty main
</code></pre></div></div>
<p>Puis il suffira de lancer les commandes suivantes :</p>
<div class="language-plaintext highlighter-rouge"><div class="highlight"><pre class="highlight"><code>sudo apt-get update
sudo apt-get install ansible
</code></pre></div></div>
<h3 id="sur-ubuntu">sur<a href="https://docs.ansible.com/ansible/intro_installation.html#latest-releases-via-apt-ubuntu"> Ubuntu</a></h3>
<div class="language-plaintext highlighter-rouge"><div class="highlight"><pre class="highlight"><code>sudo apt-get install software-properties-common
sudo apt-add-repository ppa:ansible/ansible
sudo apt-get update
sudo apt-get install ansible
</code></pre></div></div>
<p>Il suffit ensuite daller dans <code class="language-plaintext highlighter-rouge">/etc/ansible/</code> pour la suite :</p>
<div class="language-plaintext highlighter-rouge"><div class="highlight"><pre class="highlight"><code>cd /etc/ansible/
</code></pre></div></div>
<p>nous avons normalement 2 fichiers et un dossier :</p>
<ul>
<li><strong><a href="https://docs.ansible.com/ansible/intro_configuration.html">ansible.cfg</a></strong> : la configuration dansible, celle par défaut nous convient parfaitement bien pour le moment, mais ça peut valoir le coup dy jeter un coup doeil pour voir ce que lon peut faire.</li>
<li><strong><a href="https://docs.ansible.com/ansible/intro_inventory.html">hosts</a></strong> : cest dans ce fichier que nous allons indiquer nos serveurs, étape obligatoire pour la suite.</li>
<li><strong><a href="https://docs.ansible.com/ansible/playbooks_roles.html">roles</a></strong> : ce dossier nous servira surtout par la suite quand on commencera à avoir plusieurs rôles à nos <em><a href="https://docs.ansible.com/ansible/playbooks_roles.html">playbooks</a></em>.</li>
</ul>
<h2 id="inventory--hosts">Inventory / hosts</h2>
<p>Dans <code class="language-plaintext highlighter-rouge">/etc/ansible/</code>, donc, éditons notre fichier <code class="language-plaintext highlighter-rouge">hosts</code>. Nous pouvons y déclarer nos serveurs individuellement ou par groupe, par exemple :</p>
<div class="language-plaintext highlighter-rouge"><div class="highlight"><pre class="highlight"><code>serveur1.exemple.org
serveur2.exemple.org
preprod.elysee.org
8.253.9.125
[web]
skhn-web-nginx-01
skhn-web-nginx-02
[seedbox]
skhn-seedbox-01
</code></pre></div></div>
<p>Voici ma configuration actuelle, à noter que jai modifié mon <code class="language-plaintext highlighter-rouge">/etc/hosts</code> et mon <code class="language-plaintext highlighter-rouge">.ssh/config</code> pour que ça pointe vers les bons serveurs <strong>avec les bonnes clés SSH</strong> :</p>
<div class="language-plaintext highlighter-rouge"><div class="highlight"><pre class="highlight"><code>[scaleway]
skhn-001
skhn-002
[seedbox]
sb
</code></pre></div></div>
<p>Par la suite, je pourrai ainsi lancer des tâches sur tous les serveurs avec loption générique <code class="language-plaintext highlighter-rouge">all</code> ou par groupe selon vos besoins (web, bdd, wordpress, etc…). Si vous vous posez la question, le premier groupe sappelle <a href="https://www.scaleway.com/">scaleway</a> car jai pris 2 serveurs chez eux pour tester Ansible ^^).</p>
<h3 id="ping">ping</h3>
<ul>
<li>Avant toute chose, est ce que lon arrive bien à joindre les serveurs :</li>
</ul>
<div class="language-yaml highlighter-rouge"><div class="highlight"><pre class="highlight"><code><span class="s">ansible -m ping all --one-line</span>
</code></pre></div></div>
<p>Ce qui me donne :</p>
<div class="language-plaintext highlighter-rouge"><div class="highlight"><pre class="highlight"><code>skhn-002 | SUCCESS =&gt; {"changed": false, "ping": "pong"}
skhn-001 | SUCCESS =&gt; {"changed": false, "ping": "pong"}
sb | SUCCESS =&gt; {"changed": false, "ping": "pong"}
</code></pre></div></div>
<h3 id="test-ssh">test SSH</h3>
<p>Mais est ce que lon arrive à se connecter au groupe <code class="language-plaintext highlighter-rouge">scaleway</code> ? On va en profiter pour récupérer quelques infos :</p>
<div class="language-plaintext highlighter-rouge"><div class="highlight"><pre class="highlight"><code>ansible scaleway -m setup --tree /tmp/facts_servers/
</code></pre></div></div>
<p>La sortie de cette commande sera recopiée pour chaque serveur dans <code class="language-plaintext highlighter-rouge">/tmp/facts_servers/</code>, vous devriez avoir toutes les informations que vous souhaitez avoir sur vos serveurs ;-)</p>
<h3 id="et-mon-uptime-">et mon uptime ?</h3>
<div class="language-plaintext highlighter-rouge"><div class="highlight"><pre class="highlight"><code>ansible all -m command -u root --args "uptime" --one-line
</code></pre></div></div>
<p>résultat :</p>
<div class="language-plaintext highlighter-rouge"><div class="highlight"><pre class="highlight"><code>sb | SUCCESS | rc=0 | (stdout) 17:33:14 up 410 days, 21:59, 1 user, load average: 0.21, 0.16, 0.14
skhn-001 | SUCCESS | rc=0 | (stdout) 16:33:14 up 1 day, 2:05, 1 user, load average: 0.00, 0.00, 0.00
skhn-002 | SUCCESS | rc=0 | (stdout) 16:33:14 up 1 day, 2:05, 1 user, load average: 0.00, 0.00, 0.00
</code></pre></div></div>
<h2 id="installation-dune-liste-de-paquets">Installation dune liste de paquets</h2>
<p>Jaime bien avoir certains paquets installé sur tout mes serveurs, Ansible me permet de lautomatiser facilement. On commence par éditer notre nouveau fichier <code class="language-plaintext highlighter-rouge">/etc/ansible/roles/skhn_common.yml</code> pour y mettre le bloc suivant :</p>
<div class="language-yaml highlighter-rouge"><div class="highlight"><pre class="highlight"><code><span class="nn">---</span>
<span class="pi">-</span> <span class="na">hosts</span><span class="pi">:</span> <span class="s">all</span>
<span class="na">remote_user</span><span class="pi">:</span> <span class="s">root</span>
<span class="na">tasks</span><span class="pi">:</span>
<span class="pi">-</span> <span class="na">name</span><span class="pi">:</span> <span class="s">install common packages for all servers</span>
<span class="na">apt</span><span class="pi">:</span>
<span class="s">update_cache=yes</span>
<span class="s">state=latest</span>
<span class="s">name=</span>
<span class="na">with_items</span><span class="pi">:</span>
<span class="pi">-</span> <span class="s">curl</span>
<span class="pi">-</span> <span class="s">htop</span>
<span class="pi">-</span> <span class="s">ncdu</span>
<span class="pi">-</span> <span class="s">pwgen</span>
<span class="pi">-</span> <span class="s">strace</span>
<span class="pi">-</span> <span class="s">sudo</span>
<span class="pi">-</span> <span class="s">tar</span>
<span class="pi">-</span> <span class="s">unzip</span>
<span class="pi">-</span> <span class="s">vim</span>
<span class="pi">-</span> <span class="s">wget</span>
<span class="pi">-</span> <span class="s">whois</span>
<span class="pi">-</span> <span class="s">screen</span>
</code></pre></div></div>
<p>Après lavoir enregistré, il suffira de lancer la commande suivante pour installer cette liste de paquets sur tout les serveurs :</p>
<div class="language-plaintext highlighter-rouge"><div class="highlight"><pre class="highlight"><code>ansible-playbook -i hosts /etc/ansible/roles/skhn_common.yml
</code></pre></div></div>
<p>Et cétait donc notre premier rôle, yay \o/</p>
<p>Vous avez peut être remarqué 2/3 trucs :</p>
<ul>
<li>un rôle commence toujours par <code class="language-plaintext highlighter-rouge">---</code>,</li>
<li><code class="language-plaintext highlighter-rouge">hosts: all</code> est ici directement dans le fichier et non dans la commande,</li>
<li>on nomme ensuite nos tâches (<code class="language-plaintext highlighter-rouge">tasks</code>) avec <code class="language-plaintext highlighter-rouge">name</code>, ça permet de sy retrouver plus facilement et davoir un libellé humainement compréhensible à lire pendant le déroulement du rôle (on sait donc plus facilement où on en est et ce qui est en train de se passer).</li>
<li><code class="language-plaintext highlighter-rouge">update_cache=yes</code> permet de faire un <code class="language-plaintext highlighter-rouge">apt-get update</code></li>
<li>jai choisi de mettre <code class="language-plaintext highlighter-rouge">state=latest</code> et non <code class="language-plaintext highlighter-rouge">state=present</code>, jai envie que ce genre de paquet soit à jour sans que jai besoin de men occuper.</li>
</ul>
<h2 id="debug">Debug</h2>
<p>Le plus gros problème que jai eu pour le moment concerne lindentation qui est vicieuse et la syntaxe YAML.</p>
<h3 id="lindentation">Lindentation</h3>
<p>Si vous voulez vous éviter des prises de têtes qui vous font perdre quelques heures facilement, <strong>faites des indentations de DEUX espaces</strong> ! Pourquoi ? Parce que :</p>
<ul>
<li>ça, cest <strong>VALIDE</strong> (DEUX espaces) :</li>
</ul>
<div class="language-plaintext highlighter-rouge"><div class="highlight"><pre class="highlight"><code>---
- hosts: all
remote_user: root
tasks:
- name: install common packages for all servers
apt:
update_cache=yes
state=latest
name=
with_items:
- curl
- htop
</code></pre></div></div>
<ul>
<li>ça, cest <strong>INVALIDE</strong> (QUATRE espaces) :</li>
</ul>
<div class="language-plaintext highlighter-rouge"><div class="highlight"><pre class="highlight"><code>---
- hosts: all
remote_user: root
tasks:
- name: install common packages for all servers
apt:
update_cache=yes
state=latest
name=
with_items:
- curl
- htop
</code></pre></div></div>
<ul>
<li>et ça, cest <strong>VALIDE</strong> (QUATRE espaces) :</li>
</ul>
<div class="language-plaintext highlighter-rouge"><div class="highlight"><pre class="highlight"><code>---
- hosts: all
remote_user: root
tasks:
- name: install common packages for all servers
apt:

- htop
</code></pre></div></div>
<p>VOUS LA VOYEZ LA DIFFÉRENCE ? CEST CE #### DESPACEMENT ET DALIGNEMENT AVEC LE RESTE DE <code class="language-plaintext highlighter-rouge">hosts: all</code> ! Bon, une fois quon le sait, pourquoi pas, mais à cause de ça jai perdu plus dune heure hier après-midi, merci le message <code class="language-plaintext highlighter-rouge">ERROR! Syntax Error while loading YAML.</code> absolument pas parlant…</p>
<h3 id="la-syntaxe-yaml">La syntaxe YAML</h3>
<p>Si vous avez un doute sur ce que vous avez fait, ou si vos collègues sont des adeptes de la fameuse méthode “gruiiiiiik et je me casse en vacances sans vérifier si ça marche en prod”, lutilisation de <a href="https://yamllint.readthedocs.io/en/latest/">yamllint</a> est recommandée (ça, et le non moins fameux <a href="https://www.youtube.com/watch?v=7mmuQteX1qA">coup-de-clavier-dans-la-gueule</a>). Idéal en pré-commit (yamllint, pas le clavier).</p>
<p>Ansible propose aussi un check : <code class="language-plaintext highlighter-rouge">--syntax-check</code>, que lon peut utiliser de cette manière là :</p>
<div class="language-plaintext highlighter-rouge"><div class="highlight"><pre class="highlight"><code>ansible-playbook --syntax-check example-playbook.yml
ansible-playbook --syntax-check roles/*
</code></pre></div></div>
<p>Oh, et évidemment, je vous conseille beaucoup de lire les <strong><a href="https://docs.ansible.com/ansible/playbooks_best_practices.html">best practices</a></strong>.</p>
