A bucket resource.
For details about the concept, see documentation.

Field	Description
id	string ID of the bucket. Always equal to `name`, which has priority.
name	string Name of the bucket. The name is unique within the platform. For naming limitations and rules, see documentation.
folderId	string ID of the folder that the bucket belongs to.
anonymousAccessFlags	AnonymousAccessFlags Flags for configuring public (anonymous) access to the bucket's content and settings. For details, see documentation.
defaultStorageClass	string Default storage class for objects in the bucket. Supported classes are standard storage (`STANDARD`), cold storage (`COLD`, `STANDARD_IA`, `NEARLINE` all synonyms), and ice storage (`ICE` and `GLACIER` are synonyms). For details, see documentation.
versioning	enum Versioning Bucket versioning status. For details, see documentation. `VERSIONING_UNSPECIFIED` `VERSIONING_DISABLED`: The bucket is unversioned, i.e. versioning has never been enabled for the bucket, including at its creation. Objects that are stored in the bucket have a version ID of `null`. To enable versioning, change status to `VERSIONING_ENABLED` via a BucketService.Update request. Note that this action is irreversible, and a bucket with versioning enabled can never return to `VERSIONING_DISABLED` state. `VERSIONING_ENABLED`: Bucket versioning is enabled, i.e. all new objects are versioned and given a unique version ID, and objects that already existed at the time versioning was enabled will be versioned and given a unique version ID when modified by future requests. To suspend versioning, change status to `VERSIONING_SUSPENDED` via a BucketService.Update request. You cannot disable versioning altogether for a bucket that already had it enabled; objects that had version IDs will keep them. `VERSIONING_SUSPENDED`: Bucket versioning is suspended, i.e. new objects are not versioned, but objects that already existed at the time versioning was suspended are still versioned and keep their version IDs. To resume versioning, change status to `VERSIONING_ENABLED` via a BucketService.Update request.
maxSize	int64 Maximum size of the bucket, in bytes. For details, see documentation.
policy	google.protobuf.Struct Bucket policies that set permissions for actions with the bucket, its objects, and groups of objects. For details, see documentation.
acl	ACL Access control list (ACL) of the bucket. For details, see documentation.
createdAt	google.protobuf.Timestamp Creation timestamp.
cors[]	CorsRule List of rules for cross-domain requests to objects in the bucket (cross-origin resource sharing, CORS). For details, see documentation.
websiteSettings	WebsiteSettings Configuration for hosting a static website in the bucket. For details, see documentation.
lifecycleRules[]	LifecycleRule List of object lifecycle rules for the bucket. For details, see documentation.
tags[]	Tag List of tags for the bucket. For details, see documentation.
objectLock	ObjectLock Configuration for object lock on the bucket. For details about the concept, see documentation.
encryption	Encryption Configuration for bucket's encryption For detauls, see documentation

Field

Description

Field	Description
permission	enum Permission Required field. Permission granted by the grant. `PERMISSION_UNSPECIFIED` `PERMISSION_FULL_CONTROL`: Allows grantee the `PERMISSION_WRITE`, `PERMISSION_WRITE_ACP`, `PERMISSION_READ`, and `PERMISSION_READ_ACP` on the bucket. Maps to `x-amz-grant-full-control` header for bucketPutAcl method of Amazon S3-compatible HTTP API. `PERMISSION_WRITE`: Allows grantee to create new objects in the bucket. For the bucket and object owners of existing objects, also allows deletions and overwrites of those objects. Maps to `x-amz-grant-write` header for bucketPutAcl method of Amazon S3-compatible HTTP API. `PERMISSION_WRITE_ACP`: Allows grantee to write the ACL for the bucket. Maps to `x-amz-grant-write-acp` header for bucketPutAcl method of Amazon S3-compatible HTTP API. `PERMISSION_READ`: Allows grantee to list the objects in the bucket. Maps to `x-amz-grant-read` header for bucketPutAcl method of Amazon S3-compatible HTTP API. `PERMISSION_READ_ACP`: Allows grantee to read the bucket ACL Maps to `x-amz-grant-read-acp` header for bucketPutAcl method of Amazon S3-compatible HTTP API.
grantType	enum GrantType Required field. The grantee type for the grant. `GRANT_TYPE_UNSPECIFIED` `GRANT_TYPE_ACCOUNT`: A grantee is an account on the platform. For this grantee type, you need to specify the user ID in `Bucket.acl.grants.granteeId` field. To get user ID, see instruction. Maps to using `id=""` value for `x-amz-grant-` header (bucketPutAcl method of Amazon S3-compatible HTTP API). `GRANT_TYPE_ALL_AUTHENTICATED_USERS`: Grantees are all authenticated users, both from your clouds and other users' clouds. Access permission to this group allows any account on the platform to access the resource via a signed (authenticated) request. Maps to using `uri="http://acs.amazonaws.com/groups/global/AuthenticatedUsers"` value for `x-amz-grant-` header (bucketPutAcl method of Amazon S3-compatible HTTP API). `GRANT_TYPE_ALL_USERS`: Grantees are all internet users. Access permission to this group allows anyone in the world access to the resource via signed (authenticated) or unsigned (anonymous) requests. Maps to using `uri="http://acs.amazonaws.com/groups/global/AllUsers"` value for `x-amz-grant-` header (bucketPutAcl method of Amazon S3-compatible HTTP API).

If there is a match, all the allowed methods are listed in the `Access-Control-Allow-Methods` header of the response. `METHOD_UNSPECIFIED` `METHOD_GET`: HTTP `GET` method. `METHOD_HEAD`: HTTP `HEAD` method. `METHOD_POST`: HTTP `POST` method. `METHOD_PUT`: HTTP `PUT` method. `METHOD_DELETE`: HTTP `DELETE` method.
allowedHeaders[]	string List of HTTP headers allowed by the CORS rule. When a client sends a CORS-preflight `options` request with the `Access-Control-Request-Headers` header (see S3-compatible API reference), the specified headers are checked against the list of the allowed headers. If there is a match, the specified headers that are allowed are listed in the `Access-Control-Allow-Headers` header of the response. Each string in the list can contain at most one `` wildcard character that matches 0 or more characters. For example, `x-amz-` value will allow all Amazon S3-compatible headers.
allowedOrigins[]	string List of request origins allowed by the CORS rule. Each string in the list can contain at most one `` wildcard character that matches 0 or more characters. For example, `http://.example.com` value will allow requests originating from all subdomains of `example.com`.
