本指南說明在多地區環境中停用地區的程序。
停用混合型區域
- 將 Kubernetes 結構定義設為需要停用的區域。
列出目前的背景資訊,查看每個叢集的背景資訊名稱:
kubectl config get-contexts
將結構定義設為要停用的叢集和區域:
kubectl config use-context CONTEXT_NAME
其中 CONTEXT_NAME 是叢集和區域的內容名稱。
例如:
kubectl config get-contexts
CURRENT NAME CLUSTER AUTHINFO NAMESPACE gke_example-org-1_us-central1_example-cluster-1 gke_example-org-1_us-central1_example-cluster-1 gke_example-org-1_us-central1_example-cluster-1 apigee * gke_example-org-1_us-central1_example-cluster-2 gke_example-org-1_us-central1_example-cluster-2 gke_example-org-1_us-central1_example-cluster-2 apigee gke_example-org-1_us-west1_example-cluster-2 gke_example-org-1_us-west1_example-cluster-2 gke_example-org-1_us-west1_example-cluster-2 apigeekubectl config use-context gke_example-org-1_us-west1_example-cluster-2
-
驗證區域中所有 Pod 是否處於執行或已完成狀態:
kubectl get pods -n apigee
kubectl get pods -n apigee-system
-
使用 Helm 驗證元件的發布:
helm -n apigee list
helm -n apigee-system list
例如:
helm -n apigee list

驗證 Cassandra 叢集的狀態。
列出 Cassandra Pod:
kubectl get pods -n APIGEE_NAMESPACE -l app=apigee-cassandra
例如:
kubectl get pods -n apigee -l app=apigee-cassandra

逐一刪除元件。
helm -n apigee delete datastore
helm -n apigee delete telemetry
helm -n apigee delete ingress-manager
helm -n apigee delete redis
helm -n apigee delete ORG_NAME
針對每個環境重複執行下列指令:
helm -n apigee delete ENV_NAME
針對每個環境群組重複執行下列指令:
helm -n apigee delete ENV_GROUP_NAME
helm -n apigee-system delete operator
- 確認 Apigee 命名空間中沒有任何剩餘的 Pod:
kubectl get pods -n apigee
kubectl get pods -n apigee-system
- Set the context to other existing regions and make sure the cassandra datacenter is removed
from the existing ring. The output should not show the removed data center details.
kubectl exec apigee-cassandra-default-0 -n apigee -- nodetool -u JMX_USER -pw JMX_PASSWORD status
