+MariaDB-Galera service can be accessed via port 3306 on the following DNS name from within your cluster:
+{{ include "common.fullname" . }}.{{ .Release.Namespace }}.svc.cluster.local
+
+To connect to your database:
+
+1. Run a pod that you can use as a client:
+
+ kubectl run {{ include "common.fullname" . }}-client --rm --tty -i --image mariadb --command -- bash
+
+2. Connect using the mysql cli, then provide your password:
+ $ mysql -h {{ include "common.fullname" . }} {{- if .Values.mysqlRootPassword }} -p {{ .Values.mysqlRootPassword }}{{- end -}}
