Halaman ini memandu Anda cara membuat bucket penyimpanan Tulis Sekali Baca Banyak (WORM) di lingkungan air gap Google Distributed Cloud (GDC). Bagian ini mencakup prasyarat dan langkah-langkah untuk membuat bucket WORM dengan periode retensi yang ditentukan, dan untuk memberikan izin akses menggunakan binding peran. Informasi ini memungkinkan Anda menerapkan praktik retensi data dan keabadian yang ketat, sehingga memberikan penyimpanan data yang kuat dan sesuai untuk catatan dan kasus penggunaan seperti logging audit.
Halaman ini ditujukan untuk audiens seperti administrator IT dalam grup operator infrastruktur atau developer dalam grup operator aplikasi yang mengelola setelan retensi dan kepatuhan data untuk bucket penyimpanan di lingkungan yang terisolasi dari internet GDC. Untuk mengetahui informasi selengkapnya, lihat dokumentasi Audiens untuk GDC yang terisolasi dari internet.
Sebelum memulai
Namespace project mengelola resource bucket di server Management API. Anda
harus memiliki project untuk menggunakan bucket dan objek.
Anda juga harus memiliki izin bucket yang sesuai untuk melakukan operasi berikut. Lihat Memberikan akses bucket.
Membuat bucket WORM
Bucket WORM memastikan bahwa tidak ada yang menimpa objek dan objek tersebut dipertahankan selama jangka waktu minimum. Logging audit adalah contoh kasus penggunaan untuk bucket WORM.
Lakukan langkah-langkah berikut untuk membuat bucket WORM:
Tetapkan periode retensi saat membuat bucket. Misalnya, bucket contoh berikut memiliki periode retensi 365 hari.

This covers the prerequisites and steps for creating a WORM bucket with a defined retention period, and for granting access permissions using role bindings. This information lets you enforce strict data retention practices and immutability, providing robust and compliant data storage for records and use cases like audit logging.\n\nThis page is for audiences such as IT administrators within the infrastructure operator group or developers within the application operator group who manage data retention and compliance settings for storage buckets in GDC air-gapped environments. For more information, see [Audiences for GDC air-gapped documentation](/distributed-cloud/hosted/docs/latest/gdch/resources/audiences).\n\nBefore you begin\n----------------\n\nA project namespace manages bucket resources in the Management API server. You\nmust have a [project](/distributed-cloud/hosted/docs/latest/gdch/platform/pa-user/project-management) to work with buckets and objects.\n\nYou must also have the appropriate bucket permissions to perform the following\noperation. See [Grant bucket access](/distributed-cloud/hosted/docs/latest/gdch/platform/pa-user/grant-obtain-storage-access#grant_bucket_access).\n\nCreate a WORM bucket\n--------------------\n\nA WORM bucket ensures that nothing else overwrites objects and it retains them for\na minimum period of time. Audit logging is an example use case for a WORM bucket.\n| **Note:** If you attempt to overwrite an object in a WORM bucket, you will add a new version of the object. Only after a WORM object's retention period, as dictated by the bucket locking policy, is over can you proceed with object, bucket, and project deletion.\n\nTake the following steps to create a WORM bucket:\n\n1. Set a retention period when creating the bucket. For example, the following\n example bucket has a retention period of 365 days.\n\n apiVersion: object.gdc.goog/v1\n kind: Bucket\n metadata:\n name: foo logging-bucket\n namespace: foo-service\n spec:\n description: \"Audit logs for foo\"\n storageClass: Standard\n bucketPolicy:\n lockingPolicy:\n defaultObjectRetentionDays: 365\n\n2. Grant the `project-bucket-object-viewer` role to all users who need read-only\n access:\n\n apiVersion: rbac.authorization.k8s.io/v1\n kind: RoleBinding\n metadata:\n namespace: foo-service\n name: object-readonly-access\n roleRef:\n kind: Role\n name: project-bucket-object-viewer\n apiGroup: rbac.authorization.k8s.io\n subjects:\n - kind: ServiceAccount\n namespace: foo-service\n name: foo-log-processor\n - kind: User\n name: bob@example.com\n apiGroup: rbac.authorization.k8s.io\n\n3. Grant the `project-bucket-object-admin` role to users who need to write\n content to the bucket:\n\n apiVersion: rbac.authorization.k8s.io/v1\n kind: RoleBinding\n metadata:\n namespace: foo-service\n name: object-write-access\n roleRef:\n kind: Role\n name: project-bucket-object-viewer\n apiGroup: rbac.authorization.k8s.io\n subjects:\n - kind: ServiceAccount\n namespace: foo-service\n name: foo-service-account"]]
