Questa guida spiega la procedura per il ritiro di una regione in un ambiente multiregione.
Dismissione di un'area geografica ibrida
- Imposta i contesti Kubernetes per la regione che deve essere ritirata.
Elenca i tuoi contesti attuali per vedere il nome del contesto per ogni cluster:
kubectl config get-contexts
Imposta il contesto del cluster e della regione che vuoi ritirare:
kubectl config use-context CONTEXT_NAME
dove CONTEXT_NAME è il nome del contesto per il cluster e la regione.
Ad esempio:
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
-
Verifica che tutti i pod nella regione siano in stato di esecuzione o completamento:
kubectl get pods -n apigee
kubectl get pods -n apigee-system
-
Convalida la release dei componenti utilizzando Helm:
helm -n apigee list
helm -n apigee-system list
Ad esempio:
helm -n apigee list

Convalida lo stato del cluster Cassandra.
Elenca i pod Cassandra:
kubectl get pods -n APIGEE_NAMESPACE -l app=apigee-cassandra
Ad esempio:
kubectl get pods -n apigee -l app=apigee-cassandra

Elimina i componenti uno alla volta.
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
Ripeti il seguente comando per ogni ambiente:
helm -n apigee delete ENV_NAME
Ripeti il comando seguente per ogni gruppo di ambienti:
helm -n apigee delete ENV_GROUP_NAME
helm -n apigee-system delete operator
- Verifica che non ci siano pod rimanenti negli spazi dei nomi Apigee:
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
