External connections
To expose Charmed Apache Kyuubi K8s externally, use the expose-external configuration option. Possible values are: false, nodeport, and loadbalancer.
Enable external connections
By default (when expose-external=false), Charmed Apache Kyuubi K8s creates a K8s service of type ClusterIP which it provides as endpoints to the related client applications.
These endpoints are only accessible from within the K8s namespace (or Juju model) where the Charmed Apache Kyuubi K8s is deployed.
To make Charmed Apache Kyuubi K8s accessible from outside of Kubernetes, set the expose-external parameter to loadbalancer or nodeport.
We recommend exposing the service using the loadbalancer option.
When expose-external is set to loadbalancer, Charmed Apache Kyuubi K8s will provide as endpoint the K8s LoadBalancer service IP (or hostname, depending on your K8s cluster provider) and port.
juju config kyuubi-k8s expose-external=loadbalancer
Wait for the application to settle up with the active / idle status and retrieve credentials:
juju run data-integrator/0 get-credentials
The output of this command contains both the endpoint and credentials, for example:
kyuubi:
data: '{"database": "test", "external-node-connectivity": "true", "provided-secrets":
"[\"mtls-cert\"]", "requested-secrets": "[\"username\", \"password\", \"tls\",
\"tls-ca\", \"uris\", \"read-only-uris\"]"}'
database: test
