Pour déployer votre application sur App Engine, vous devez créer un projet Google Cloud et les ressources de votre application App Engine.
Le projet Google Cloud est un conteneur de niveau supérieur qui contient votre application App Engine et d'autres ressources Google Cloud .
L'application App Engine est une ressource que vous devez créer pour activer App Engine. La ressource d'application App Engine définit la région dans laquelle vous souhaitez exécuter votre service Web et stocker les paramètres, identifiants et métadonnées associés. Une seule ressource d'application App Engine peut être créée par projet Google Cloud , et la région spécifiée ne peut plus être modifiée une fois ces ressources créées.
Si vous disposez déjà d'un projet Google Cloud avec App Engine et l'API Cloud Build activée, vous pouvez passer à la page Écrire un service Web.
Créer un projet Google Cloud
Sign in to your Google Cloud account. If you're new to
Google Cloud,
create an account to evaluate how our products perform in
real-world scenarios. New customers also get $300 in free credits to
run, test, and deploy workloads.
In the Google Cloud console, on the project selector page,
select or create a Google Cloud project.
Pour initialiser la gcloud CLI, exécutez la commande suivante :
gcloudinit
Exécutez la commande gcloud suivante pour activer App Engine et créer les ressources d'application associées. Notez que l'emplacement que vous sélectionnez ne peut pas être modifié ultérieurement.
App Engine est régional, ce qui signifie que l'infrastructure qui exécute vos applications est située dans une région spécifique, et que Google la gère de sorte qu'elle soit disponible de manière redondante dans toutes les zones de cette région.
Lors de la sélection d'une région dans laquelle exécuter vos applications, vous devez tout d'abord considérer vos exigences en matière de latence, de disponibilité et de durabilité. Vous pouvez généralement sélectionner la région la plus proche des utilisateurs de votre application, mais pensez aussi aux emplacements où App Engine est disponible ainsi qu'aux emplacements des autres produits et servicesGoogle Cloud que votre application utilise. L'utilisation de services situés dans des emplacements différents peut avoir des répercussions sur la latence de votre application, ainsi que sur les tarifs.
Une fois que vous avez défini la région d'une application, vous ne pouvez plus la modifier.
Si vous avez déjà créé une application App Engine, vous pouvez afficher sa région en effectuant l'une des opérations suivantes :

You can generally\nselect the region nearest to your app's users, but you should consider [the\nlocations where App Engine is available](/about/locations#region)\nas well as the [locations](/about/locations#region) of the other\nGoogle Cloud products and services that your app uses. Using services\nacross multiple locations can affect your app's latency as well as its\n[pricing](/appengine/pricing).\n\nYou cannot change an app's region after you set it.\n| **Note:** Two locations, which are called `europe-west` and `us-central` in App Engine commands and in the Google Cloud console, are called `europe-west1` and `us-central1`, respectively, elsewhere in Google documentation.\n\nIf you already created an App Engine application, you can view its\nregion by doing one of the following:\n\n- Run the `gcloud app describe` command.\n\n- Open the\n [App Engine Dashboard in the Google Cloud console](https://console.cloud.google.com/appengine).\n The region appears near the top of the page.\n\nOK\n\nNext steps\n\nNow that your Google Cloud project is set up, you're ready to\nwrite a basic web service."]]
