************************
******* Services *******
************************
THRIFT_BINARY:
- To access kyuubi-thrift-binary service within the cluster, use the following URL:
    kyuubi-thrift-binary.kyuubi.svc.cluster.local
- To access kyuubi-thrift-binary service from outside the cluster for debugging, run the following command:
    kubectl port-forward svc/kyuubi-thrift-binary 10009:10009 -n kyuubi
  and use 127.0.0.1:10009

Uninstall the chart#

helm uninstall kyuubi -n kyuubi

Configure chart release#

Specify configuration properties using --set flag. For example, to install the chart with replicaCount set to 1, use the following command:

helm install kyuubi ${KYUUBI_HOME}/charts/kyuubi -n kyuubi --create-namespace --set replicaCount=1

Also, custom values file can be used to override default property values. For example, create myvalues.yaml to specify replicaCount and resources:

replicaCount: 1

resources:
  requests:
    cpu: 2
    memory: 4Gi
  limits:
    cpu: 4
    memory: 10Gi

and use it to override default chart values with -f flag:

helm install kyuubi ${KYUUBI_HOME}/charts/kyuubi -n kyuubi --create-namespace -f myvalues.yaml

Access logs#

List all pods in the release namespace:

kubectl get pod -n kyuubi

Find Kyuubi pods:

NAME                      READY   STATUS    RESTARTS   AGE
kyuubi-5b6d496c98-kbhws   1/1     Running   0          38m
kyuubi-5b6d496c98-lqldk   1/1     Running   0          38m

Then, use pod name to get logs:

kubectl logs kyuubi-5b6d496c98-kbhws -n kyuubi
