This guide explains the procedure to decommission a region in a multi region environment.
Decommission a hybrid region
- Set the kubernetes contexts to the region that needs to be decommissioned.
List your current contexts to see the context name for each cluster:
kubectl config get-contexts
Set the context to the cluster and region you want to decommission:
kubectl config use-context CONTEXT_NAME
Where CONTEXT_NAME is the context name for the cluster and region.
For example:
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
- Delete the Apigee instance in the context you just selected with the
apigeectl
command:apigeectl delete --all -f overrides.yaml
- Check the current Kubernetes pods:
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
