記錄

Kf 提供多種記錄類型。本文將說明這些記錄和存取方式。

應用程式記錄檔

所有寫入標準輸出 stdout 和標準錯誤 stderr 的記錄都會上傳至 Cloud Logging，並儲存在記錄名稱 user-container 下。

開啟 Cloud Logging 並執行下列查詢：

resource.type="k8s_container"
log_name="projects/YOUR_PROJECT_ID/logs/user-container"
resource.labels.project_id=YOUR_PROJECT_ID
resource.labels.location=GCP_COMPUTE_ZONE (e.g. us-central1-a)
resource.labels.cluster_name=YOUR_CLUSTER_NAME
resource.labels.namespace_name=YOUR_KF_SPACE_NAME
resource.labels.pod_name:YOUR_KF_APP_NAME

您應該會看到所有應用程式記錄，這些記錄會寫入標準 stdout 和標準錯誤 stderr。

應用程式的存取記錄

Kf 會使用 Istio 補充物注入功能提供存取記錄。存取記錄會儲存在記錄名稱 server-accesslog-stackdriver 下。

開啟 Cloud Logging 並執行下列查詢：

resource.type="k8s_container"
log_name="projects/YOUR_PROJECT_ID/logs/server-accesslog-stackdriver"
resource.labels.project_id=YOUR_PROJECT_ID
resource.labels.location=GCP_COMPUTE_ZONE (e.g. us-central1-a)
resource.labels.cluster_name=YOUR_CLUSTER_NAME
resource.labels.namespace_name=YOUR_KF_SPACE_NAME
resource.labels.pod_name:YOUR_KF_APP_NAME

您應該會看到應用程式的存取記錄。存取記錄範例：

稽核記錄

稽核記錄會依時間順序記錄對 Kubernetes API 伺服器做出的呼叫。Kubernetes 稽核記錄項目適合用於調查可疑的 API 要求、收集統計資料，或是針對不想要的 API 呼叫建立監控快訊。

開啟 Cloud Logging 並執行下列查詢：

resource.type="k8s_container"
log_name="projects/YOUR_PROJECT_ID/logs/cloudaudit.googleapis.com%2Factivity"
resource.labels.project_id=YOUR_PROJECT_ID
resource.labels.location=GCP_COMPUTE_ZONE (e.g. us-central1-a)
resource.labels.cluster_name=YOUR_CLUSTER_NAME
protoPayload.request.metadata.name=YOUR_APP_NAME
protoPayload.methodName:"deployments."

您應該會看到對 Kubernetes API 伺服器做出的呼叫追蹤記錄。

記錄存取權控管

請按照這裡的操作說明，為開發人員和團隊其他成員提供記錄存取權。roles/logging.viewer 角色可提供記錄檔的唯讀存取權。

記錄檔路由器

您也可以使用記錄檔路由器，將記錄檔轉送至支援的目的地。
