Este guia explica o procedimento para desativar uma região num ambiente de várias regiões.
Desative uma região híbrida
- Defina os contextos do Kubernetes para a região que tem de ser desativada.
Liste os seus contextos atuais para ver o nome do contexto de cada cluster:
kubectl config get-contexts
Defina o contexto para o cluster e a região que quer desativar:
kubectl config use-context CONTEXT_NAME
Onde CONTEXT_NAME é o nome do contexto para o cluster e a região.
Por exemplo:
kubectl config get-contextsCURRENT 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 -
Valide se todos os pods na região estão em estado de execução ou concluído:
kubectl get pods -n apigee
kubectl get pods -n apigee-system
-
Valide a versão dos componentes com o Helm:
helm -n apigee list
helm -n apigee-system list
Por exemplo:
helm -n apigee listNAME NAMESPACE REVISION UPDATED STATUS CHART APP VERSION datastore apigee 2 2024-03-29 17:08:07.917848253 +0000 UTC deployed apigee-datastore-1.12.0 1.12.0 ingress-manager apigee 2 2024-03-29 17:21:02.917333616 +0000 UTC deployed apigee-ingress-manager-1.12.0 1.12.0 redis apigee 2 2024-03-29 17:19:51.143728084 +0000 UTC deployed apigee-redis-1.12.0 1.12.0 telemetry apigee 2 2024-03-29 17:16:09.883885403 +0000 UTC deployed apigee-telemetry-1.12.0 1.12.0 exampleor apigee 2 2024-03-29 17:21:50.899855344 +0000 UTC deployed apigee-org-1.12.0 1.12.0 -
Valide o estado do cluster do Cassandra.
Apresente os pods do Cassandra:
kubectl get pods -n APIGEE_NAMESPACE -l app=apigee-cassandra
Por exemplo:
kubectl get pods -n apigee -l app=apigee-cassandraNAME READY STATUS RESTARTS AGE apigee-cassandra-default-0 1/1 Running 0 2h apigee-cassandra-default-1 1/1 Running 0 2h apigee-cassandra-default-2 1/1 Running 0 2h apigee-cassandra-default-3 1/1 Running 0 16m apigee-cassandra-default-4 1/1 Running 0 14m apigee-cassandra-default-5 1/1 Running 0 13m apigee-cassandra-default-6 1/1 Running 0 9m apigee-cassandra-default-7 1/1 Running 0 9m apigee-cassandra-default-8 1/1 Running 0 8m - Elimine a instância do Apigee no contexto que acabou de selecionar:
Elimine os componentes um de cada vez.
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
Repita o seguinte comando para cada ambiente:
helm -n apigee delete ENV_NAME
Repita o seguinte comando para cada grupo de ambientes:
helm -n apigee delete ENV_GROUP_NAME
helm -n apigee-system delete operator
- Verifique se não existem pods restantes nos espaços de nomes do 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
