En esta página, se describe cómo determinar el diseño de almacenamiento de tu bucket. El diseño
de almacenamiento hace referencia a cómo se organizan los objetos dentro de un bucket, ya sea en un espacio de nombres
plano o en un espacio de nombres jerárquico. El diseño es importante para
las aplicaciones que interactúan con el bucket, ya que los métodos de acceso y manipulación
de objetos varían según el diseño. El diseño de almacenamiento también incluye información
acerca de la ubicación del bucket.
Con la API de getStorageLayout, tu aplicación puede adaptar su
comportamiento de acuerdo con si un bucket usa o no espacios de nombres jerárquicos, lo que garantiza
una compatibilidad óptima y aprovecha las funciones adecuadas según la
configuración del bucket.
Funciones necesarias
Para obtener los permisos necesarios para obtener el diseño de almacenamiento de un bucket de Cloud Storage, pídele a tu administrador que te otorgue el rol de usuario de objetos de almacenamiento (roles/storage.objectUser) en el bucket.
El rol contiene el permiso storage.objects.list, que se
requiere para obtener el diseño de almacenamiento del bucket.

Storage\nlayout refers to how objects are organized within a bucket, either in a flat\nnamespace or a [hierarchical namespace](/storage/docs/hns-overview). The layout is important for\napplications that interact with the bucket, as object access and manipulation\nmethods vary depending on the layout. Storage layout also includes information\nabout the bucket's location.\n\nBy using the [`getStorageLayout`](/storage/docs/json_api/v1/buckets/getStorageLayout) API, your application can adapt its\nbehavior based on whether a bucket uses hierarchical namespace or not, ensuring\noptimal compatibility and leveraging the appropriate features based on the\nbucket configuration.\n\n#### Roles required\n\nIn order to get the required permissions for getting the storage layout of a Cloud Storage bucket , ask your administrator to grant you the Storage Object User (`roles/storage.objectUser`) role on the bucket.\n\nThe role contains the `storage.objects.list` permission, which is\nrequired to get the storage layout of the bucket.\n\nYou might also be able to get this permission with other [custom roles](/iam/docs/creating-custom-roles) or\n[predefined roles](/iam/docs/understanding-roles#predefined). To see which roles are associated with which permissions, refer to [IAM roles for Cloud Storage.](/storage/docs/access-control/iam-roles)\n\nFor instructions on granting roles on buckets, see [Use IAM with buckets.](/storage/docs/access-control/using-iam-permissions)\n\nGet a bucket's storage layout\n-----------------------------\n\n### Command line\n\nUse the [`gcloud alpha storage buckets describe`](/sdk/gcloud/reference/alpha/storage/buckets/describe) command with the `--format` flag: \n\n```\ngcloud alpha storage buckets describe gs://BUCKET_NAME --raw --format=\"default(hierarchicalNamespace)\"\n```\n\nWhere:\n\n- \u003cvar translate=\"no\"\u003eBUCKET_NAME\u003c/var\u003e is the name of the relevant bucket. For example, `my-bucket`.\n\nIf successful and hierarchical namespace is enabled, the response looks\nsimilar to the following example: \n\n```\n hierarchicalNamespace:\n enabled: true\n```\n\n### JSON API\n\n1. Have gcloud CLI [installed and initialized](/sdk/docs/install), which lets\n you generate an access token for the `Authorization` header.\n\n\n2.\n\n Use [`cURL`](http://curl.haxx.se/) to call the [JSON API](/storage/docs/json_api)\n with a [`getStorageLayout`](/storage/docs/json_api/v1/buckets/getStorageLayout) request: \n\n ```\n curl -X GET \\\n -H \"Authorization: Bearer $(gcloud auth print-access-token)\" \\\n \"https://storage.googleapis.com/storage/v1/b/BUCKET_NAME/storageLayout\"\n ```\n\n Where \u003cvar translate=\"no\"\u003eBUCKET_NAME\u003c/var\u003e is the name of the\n relevant bucket. For example, `my-bucket`.\n\n If successful, the response looks like the following example:\n\n \u003cbr /\u003e\n\n ```json\n {\n \"kind\": \"storage#storageLayout\",\n \"bucket\": \"my-bucket\",\n \"location\": \"us-central1\",\n \"locationType\": \"region\",\n \"hierarchicalNamespace\":{enabled: true},\n }\n ```\n\n \u003cbr /\u003e\n\nWhat's next\n-----------\n\n- [Understand folders](/storage/docs/folders-overview).\n- [Create and manage folders](/storage/docs/create-folders).\n- [Rename folders](/storage/docs/rename-hns-folders).\n\nTry it for yourself\n-------------------\n\n\nIf you're new to Google Cloud, create an account to evaluate how\nCloud Storage performs in real-world\nscenarios.
