Cassandra Thrift can be accessed via port {{ .Values.config.ports.thrift }} on the following DNS name from within your cluster:

If you want to connect to the remote instance with your local Cassandra CQL cli. To forward the API port to localhost:9042 run the following:
- kubectl port-forward --namespace {{ .Release.Namespace }} $(kubectl get pods --namespace {{ .Release.Namespace }} -l app={{ template "fullname" . }} -o jsonpath='{ .items[0].metadata.name }') 9042:{{ .Values.config.ports.cql }}
- kubectl port-forward --namespace {{ .Release.Namespace }} $(kubectl get pods --namespace {{ .Release.Namespace }} -l app={{ template "cassandra.fullname" . }} -o jsonpath='{ .items[0].metadata.name }') 9042:{{ .Values.config.ports.cql }}

If you want to connect to the Cassandra CQL run the following:
{{- if contains "NodePort" .Values.service.type }}
- export CQL_PORT=$(kubectl get --namespace {{ .Release.Namespace }} -o jsonpath="{.spec.ports[0].nodePort}" services {{ template "fullname" . }})
- export CQL_PORT=$(kubectl get --namespace {{ .Release.Namespace }} -o jsonpath="{.spec.ports[0].nodePort}" services {{ template "cassandra.fullname" . }})
- export CQL_HOST=$(kubectl get nodes --namespace {{ .Release.Namespace }} -o jsonpath="{.items[0].status.addresses[0].address}")
- cqlsh $CQL_HOST $CQL_PORT

{{- else if contains "LoadBalancer" .Values.service.type }}
NOTE: It may take a few minutes for the LoadBalancer IP to be available.
Watch the status with: 'kubectl get svc --namespace {{ .Release.Namespace }} -w {{ template "fullname" . }}'
- export SERVICE_IP=$(kubectl get svc --namespace {{ .Release.Namespace }} {{ template "fullname" . }} -o jsonpath='{.status.loadBalancer.ingress[0].ip}')
Watch the status with: 'kubectl get svc --namespace {{ .Release.Namespace }} -w {{ template "cassandra.fullname" . }}'
- export SERVICE_IP=$(kubectl get svc --namespace {{ .Release.Namespace }} {{ template "cassandra.fullname" . }} -o jsonpath='{.status.loadBalancer.ingress[0].ip}')
- echo cqlsh $SERVICE_IP
{{- else if contains "ClusterIP" .Values.service.type }}
- kubectl port-forward --namespace {{ .Release.Namespace }} $(kubectl get pods --namespace {{ .Release.Namespace }} -l "app={{ template "fullname" . }}" -o jsonpath="{.items[0].metadata.name}") 9042:{{ .Values.config.ports.cql }}
- kubectl port-forward --namespace {{ .Release.Namespace }} $(kubectl get pods --namespace {{ .Release.Namespace }} -l "app={{ template "cassandra.fullname" . }}" -o jsonpath="{.items[0].metadata.name}") 9042:{{ .Values.config.ports.cql }}
echo cqlsh 127.0.0.1 9042
{{- end }}

You can also see the cluster status by run the following:
- kubectl exec -it --namespace {{ .Release.Namespace }} $(kubectl get pods --namespace {{ .Release.Namespace }} -l app={{ template "fullname" . }} -o jsonpath='{.items[0].metadata.name}') nodetool status
- kubectl exec -it --namespace {{ .Release.Namespace }} $(kubectl get pods --namespace {{ .Release.Namespace }} -l app={{ template "cassandra.fullname" . }} -o jsonpath='{.items[0].metadata.name}') nodetool status

To tail the logs for the Cassandra pod run the following:
- kubectl logs -f --namespace {{ .Release.Namespace }} $(kubectl get pods --namespace {{ .Release.Namespace }} -l app={{ template "fullname" . }} -o jsonpath='{ .items[0].metadata.name }')
- kubectl logs -f --namespace {{ .Release.Namespace }} $(kubectl get pods --namespace {{ .Release.Namespace }} -l app={{ template "cassandra.fullname" . }} -o jsonpath='{ .items[0].metadata.name }')
