查看持續驗證記錄

本指南說明如何查看持續驗證 (CV) 透過以檢查為準的平台政策產生的 Cloud Logging 項目。如要查看舊版持續驗證 (已淘汰) 項目，請參閱「查看舊版 CV 記錄」。

CV 記錄會檢查 podEvent 項目中的相關問題。 configErrorEvent項目中與 CV 記錄設定相關的問題，例如平台政策或 IAM 角色設定錯誤。

查看履歷表項目的記錄

您可以搜尋 Cloud Logging 項目，找出CV 設定錯誤和CV 平台政策驗證違規事項。

CV 會在 24 小時內將錯誤和違規事項記錄至 Cloud Logging。通常在幾小時內就能看到記錄項目。

查看 CV 設定錯誤記錄

如要查看 CV 設定錯誤記錄，請執行下列指令：

gcloud logging read \
     --order="desc" \
     --freshness=7d \
     --project=CLUSTER_PROJECT_ID \
    'logName:"binaryauthorization.googleapis.com%2Fcontinuous_validation" "configErrorEvent"'

以下輸出內容顯示設定錯誤，其中找不到 CV 平台政策：

{
  "insertId": "141d4f10-72ea-4a43-b3ec-a03da623de42",
  "jsonPayload": {
    "@type": "type.googleapis.com/google.cloud.binaryauthorization.v1beta1.ContinuousValidationEvent",
    "configErrorEvent": {
      "description": "Cannot monitor cluster 'us-central1-c.my-cluster': Resource projects/123456789/platforms/gke/policies/my-policy does not exist."
    }
  },
  "resource": {
    "type": "k8s_cluster",
    "labels": {
      "cluster_name": "my-cluster",
      "location": "us-central1-c",
      "project_id": "my-project"
    }
  },
  "timestamp": "2024-05-28T15:31:03.999566Z",
  "severity": "WARNING",
  "logName": "projects/my-project/logs/binaryauthorization.googleapis.com%2Fcontinuous_validation",
  "receiveTimestamp": "2024-05-28T16:30:56.304108670Z"
}

查看 CV 平台政策驗證違規事項

如果沒有任何圖片違反您啟用的平台政策，記錄檔中就不會顯示任何項目。

如要查看過去 7 天的 CV 記錄項目，請執行下列指令：

gcloud logging read \
     --order="desc" \
     --freshness=7d \
     --project=CLUSTER_PROJECT_ID \
    'logName:"binaryauthorization.googleapis.com%2Fcontinuous_validation" "policyName"'

將 CLUSTER_PROJECT_ID 替換為叢集專案 ID。

支票類型

CV 記錄會將違規資訊檢查到 checkResults。在項目中，值 checkType 表示檢查。各項檢查的值如下：

  • ImageFreshnessCheck
  • SigstoreSignatureCheck
  • SimpleSigningAttestationCheck
  • SlsaCheck
  • TrustedDirectoryCheck
  • VulnerabilityCheck
