Déploiement d'applications sur Amazon EC2 avec AWS CloudFormation
Vous pouvez utiliser AWS CloudFormation pour installer, configurer et lancer automatiquement des applications dans des instances Amazon EC2. Cette approche vous permet de dupliquer facilement les déploiements et de mettre à jour les installations existantes sans avoir à vous connecter directement à l'instance. Vous évitez ainsi de perdre du temps et de l'énergie.
CloudFormation comprend un ensemble de scripts d'assistant (cfn-init, cfn-signal, cfn-get-metadata et cfn-hup) qui sont basés sur cloud-init. Vous appelez ces scripts d'assistant à partir de vos modèles CloudFormation pour installer, configurer et mettre à jour des applications dans les instances Amazon EC2 qui font partie du même modèle.
La procédure suivante décrit comment créer un modèle qui lance une pile LAMP en utilisant des scripts d'assistant cfn pour installer, configurer et lancer Apache, MySQL et PHP. Vous commencez par un modèle simple qui configure une instance Amazon EC2 de base sur Amazon Linux, puis continuez à ajouter des données au modèle jusqu'à ce qu'il décrive une pile LAMP complète.
Instance Amazon EC2 de base
Vous commencez avec un modèle de base qui définit une instance Amazon EC2 unique avec un groupe de sécurité qui autorise le trafic SSH sur le port 22 et le trafic HTTP sur le port 80, comme illustré dans l'exemple suivant :

En plus de l'instance Amazon EC2 et du groupe de sécurité, nous créons trois paramètres d'entrée qui spécifient le type d'instance, une paire de clés Amazon EC2 à utiliser pour l'accès SSH et une plage d'adresses IP qui permet d'accéder à l'instance. La section des mappages garantit qu'CloudFormation utilise l'ID d'AMI correct pour le type d'instance Amazon EC2 et la région de la pile. Enfin, la section Outputs génère l'URL publique du serveur web.
Installation LAMP
Vous utilisez le modèle Amazon EC2 de base précédent comme support pour installer automatiquement Apache, MySQL et PHP. Pour installer ces applications, vous ajouterez les propriétés UserData et Metadata. Toutefois, le modèle ne configurera pas et ne démarrera pas les applications avant la section suivante.
Dans l'exemple suivant, les sections marquées d'une ellipse (...) sont omises pour plus de facilité.

La propriété UserData exécute deux commandes shell : installation des scripts d'assistant CloudFormation et exécution du script d'assistant cfn-init. Etant donné que les scripts d'assistant sont mis à jour régulièrement, l'exécution de la commande yum install -y
aws-cfn-bootstrap garantit que vous obtenez les derniers scripts d'assistant. Lorsque vous exécutez cfn-init, il lit les métadonnées à partir de la ressource AWS::CloudFormation::Init, qui décrit les actions à effectuer par cfn-init. Par exemple, vous pouvez utiliser cfn-init et AWS::CloudFormation::Init pour installer les packages, écrire des fichiers sur le disque ou démarrer un service. Dans notre cas, cfn-init installe les packages énumérés (httpd, mysql et php) et crée le fichier /var/www/html/index.php (exemple d'application PHP).
Configuration LAMP
Maintenant que nous disposons d'un modèle qui installe Linux, Apache, MySQL et PHP, nous devons le développer de sorte qu'il configure et exécute automatiquement Apache, MySQL et PHP. Dans l'exemple suivant, nous développons la section Parameters, la ressource AWS::CloudFormation::Init et la propriété UserData afin de terminer la configuration. Comme avec le modèle précédent, les sections marquées d'une ellipse (...) sont omises pour plus de facilité. Les ajouts apportés au modèle sont affichés sous la forme de texte rouge en italique.
L’exemple définit les paramètres DBUsername et DBPassword avec la propriété NoEcho définie sur true. Si vous définissez l'attribut NoEcho sur true, CloudFormation renvoie la valeur du paramètre masquée sous forme d'astérisques (*****) pour tous les appels qui décrivent la pile ou les événements de pile, à l'exception des informations stockées dans les emplacements spécifiés ci-dessous.
Important
L'utilisation de l'attribut NoEcho ne masque aucune information stockée dans les lieux suivants :
La section de modèle
MetadataCloudFormation ne transforme pas, ne modifie pas, ne rédige aucune information que vous incluez dans la sectionMetadata. Pour de plus amples informations, veuillez consulter Métadonnées.La section de modèle
OutputsPour de plus amples informations, veuillez consulter SortiesL’attribut
Metadatad'une définition de ressource. Pour de plus amples informations, veuillez consulter Attribut de métadonnées.
Nous vous recommandons vivement de ne pas utiliser ces mécanismes pour inclure des informations sensibles, telles que des mots de passe ou des secrets.
Important
Plutôt que d'intégrer des informations sensibles directement dans vos modèles CloudFormation, nous vous recommandons d'utiliser des paramètres dynamiques dans le modèle de pile pour faire référence aux informations sensibles stockées et gérées en dehors de CloudFormation, par exemple dans AWS Systems Manager Parameter Store ou AWS Secrets Manager.

Cet exemple ajoute davantage de paramètres pour obtenir des informations de configuration de la base de données MySQL, telles que le nom de la base de données, le nom d'utilisateur, le mot de passe et le mot de passe racine. Les paramètres contiennent également des contraintes qui détectent les valeurs mal formatées avant que CloudFormation crée la pile.
Dans la ressource AWS::CloudFormation::Init, nous avons ajouté un fichier de configuration MySQL, contenant le nom de la base de données, le nom d'utilisateur et le mot de passe. Cet exemple ajoute également une propriété services pour s'assurer que les services httpd et mysqld sont exécutés (la valeur ensureRunning est définie sur true) et qu'ils seront redémarrés en cas de redémarrage de l'instance (la valeur enabled est définie sur true). Nous vous conseillons d'inclure également le script d'assistant cfn-hup, qui vous permet d'apporter des mises à jour de configuration aux instances exécutées en mettant à jour le modèle de la pile. Par exemple, vous pouvez modifier l'exemple d'application PHP, puis exécuter une mise à jour de la pile pour déployer cette modification.
Pour exécuter les commandes MySQL une fois l'installation terminée, l'exemple ajoute une autre jeu de configuration. Les jeux de configuration sont particulièrement utiles lorsqu'une série de tâches doivent être exécutées dans un ordre spécifique. Cet exemple exécute d'abord le jeu de configuration Install, puis le jeu de configuration Configure. Le jeu de configuration Configure spécifie le mot de passe racine de la base de données, puis crée une base de données. Dans la section Commands, les commandes sont traitées par ordre alphabétique en fonction de leur nom. Dès lors, l'exemple ajoute un nombre avant de chaque nom de commande pour indiquer son ordre d'exécution souhaité.
Attribut CreationPolicy
Enfin, vous devez faire en sorte que CloudFormation ne termine la création de la pile que lorsque tous les services (par exemple, Apache et MySQL) sont en cours d'exécution, et non pas après que toutes les ressources de la pile sont créées. En d'autres termes, si vous utilisez le modèle de la section précédente pour lancer une pile, CloudFormation définit le statut CREATE_COMPLETE pour cette dernière après avoir créé toutes les ressources. Toutefois, si un ou plusieurs services n'ont pas démarré, CloudFormation définit tout de même le statut CREATE_COMPLETE pour la pile. Pour éviter la définition de l'état CREATE_COMPLETE tant que tous les services n'ont pas démarré avec succès, vous pouvez ajouter un attribut Attribut CreationPolicy à l'instance. Cet attribut active le statut CREATE_IN_PROGRESS pour l'instance jusqu'à ce qu'CloudFormation reçoive le nombre de signaux de réussite requis ou jusqu'à ce que le délai expire. Vous pouvez ainsi déterminer quand l'instance a été créée avec succès.
L'exemple suivant ajoute une politique de création à l'instance Amazon EC2 afin de garantir que cfn-init termine l'installation et la configuration LAMP avant la fin de la création de la pile. Outre la politique de création, cet exemple doit exécuter le script d'assistant cfn-signal pour signaler à CloudFormation que toutes les applications sont installées et configurées.

L'attribut de la politique de création utilise le format ISO 8601 pour définir un délai d'expiration de 5 minutes. Et comme il ne s'agit ici que de la configuration d'une instance, vous ne devez attendre qu'un signal de réussite, qui est le nombre par défaut.
Dans la propriété UserData, le modèle exécute le script cfn-signal pour envoyer un signal de réussite avec un code de sortie si tous les services sont configurés et s'ils ont tous démarré. Lorsque vous utilisez le script cfn-signal, vous devez inclure l'ID ou le nom de la pile et l'ID logique de la ressource que vous souhaitez signaler. En cas d'échec de la configuration, cfn-signal envoie un signal d'échec qui entraîne l'échec de la création des ressources. La création de ressource échoue également si CloudFormation ne reçoit pas de signal de réussite avant l'expiration du délai d'attente.
L'exemple suivant présente le modèle complet final.
