為儲存空間值區設定物件生命週期政策

本頁說明如何為 Google Distributed Cloud (GDC) 實體隔離儲存空間值區設定物件生命週期政策。

事前準備

專案命名空間可管理 Management API 伺服器中的 bucket 資源。您必須擁有專案，才能使用 bucket 和物件。

您也必須具備適當的 bucket 權限，才能執行下列作業。請參閱「授予 bucket 存取權」。

在值區中設定物件生命週期政策

您可以使用物件生命週期政策，自動管理值區中的物件。這有助於您在資料的整個生命週期內，更有效率地儲存資料。生命週期設定是一系列規則，可根據特定比對條件，讓一組物件過期。

您可以建立有或沒有物件生命週期政策的值區。建立值區後，您可以套用新的生命週期政策、更新現有政策或移除現有政策。

對於未啟用版本控管的值區，到期表示系統會非同步永久移除物件。

如果是已啟用版本管理功能的 bucket，如果目前的物件版本不是刪除標記，到期會使目前的版本成為非現行版本，然後在目前的版本中新增刪除標記。

如要設定及修改物件生命週期政策，請更新 Bucket.spec.bucketPolicy.lifecyclePolicy 欄位。

CLI

以下是幾個值區資源的範例，這些資源設定了不同的物件生命週期政策：

apiVersion: object.gdc.goog/v1
kind: Bucket
metadata:
  name: BUCKET_NAME
  namespace: NAMESPACE_NAME
spec:
  description: "Bucket with lifecycle rule to expire all objects after 365 days"

  bucketPolicy:
    lifecyclePolicy:
      enable: true
      lifecycleRules:
      - expiration:
          days: 365
        id: expire-all-after-365-days
        status: Enabled
----------
apiVersion: object.gdc.goog/v1

      - expiration:
          days: 30
        id: expire-logs-dir-after-30-days
        status: Enabled
        filter:

apiVersion: object.gdc.goog/v1

  bucketPolicy:
    lifecyclePolicy:
      enable: true
      lifecycleRules:
      - noncurrentExpiration:
          noncurrentDays: 90
        id: expire-noncurrent-after-90-days
        status: Enabled
----------
apiVersion: object.gdc.goog/v1

  storageClass: Standard
  bucketPolicy:
    lifecyclePolicy:
      enable: true
      lifecycleRules:
      - expiration:
          date: "2027-01-01T00:00:00Z"
        id: expire-on-specific-date
        status: Enabled
----------
apiVersion: object.gdc.goog/v1
kind: Bucket
metadata:
  name: BUCKET_NAME
  namespace: NAMESPACE_NAME
spec:
  description: "Bucket with multiple lifecycle rules and advanced filters"
  storageClass: Standard
  bucketPolicy:
    lifecyclePolicy:
      enable: true
      lifecycleRules:
      # Rule 1: Expire objects in 'tmp/' directory AND tagged with 'status=ready' after 7 days
      - expiration:
          days: 7
        id: expire-ready-tmp-objects
        status: Enabled
        filter:
          prefixFilter: "tmp/"
          tagFilters:
          - key: status
            value: ready
      # Rule 2: Expire all objects in 'logs/' directory after 90 days
      - expiration:
          days: 90
        id: expire-logs-after-90-days
        status: Enabled
        filter:
          prefixFilter: "logs/"

生命週期政策更新後，會套用至現有物件和更新後上傳的物件。

如果值區也設定了物件鎖定，系統會在保留天數結束前，保護物件不會過期。
