+Cassandra CQL can be accessed via port {{ .Values.config.ports.cql }} on the following DNS name from within your cluster:
+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 "cassandra.name" . }},release={{ .Release.Name }} -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=$(kubectl get --namespace {{ .Release.Namespace }} -o jsonpath="{.spec.ports[0].nodePort}" services {{ template "cassandra.fullname" . }})
+- export CQL_HOST=$(kubectl get nodes --namespace {{ .Release.Namespace }} -o jsonpath="{.items[0].status.addresses[0].address}")
+- cqlsh $CQL_HOST $CQL_PORT
+
+{{- else if contains "LoadBalancer" .Values.service.type }}
+  NOTE: It may take a few minutes for the LoadBalancer IP to be available.
+        Watch the status with: 'kubectl get svc --namespace {{ .Release.Namespace }} -w {{ template "cassandra.fullname" . }}'
+- export SERVICE_IP=$(kubectl get svc --namespace {{ .Release.Namespace }} {{ template "cassandra.fullname" . }} -o jsonpath='{.status.loadBalancer.ingress[0].ip}')

+  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 "cassandra.name" . }},release={{ .Release.Name }} -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 "cassandra.name" . }},release={{ .Release.Name }} -o jsonpath='{ .items[0].metadata.name }')
+
+{{- if not .Values.persistence.enabled }}
+
+Note that the cluster is running with node-local storage instead of PersistentVolumes. In order to prevent data loss,
+pods will be decommissioned upon termination. Decommissioning may take some time, so you might also want to adjust the
+pod termination gace period, which is currently set to {{ .Values.podSettings.terminationGracePeriodSeconds }} seconds.
