+# MariaDB
+
+[MariaDB](https://mariadb.org) is one of the most popular database servers in the world. It’s made by the original developers of MySQL and guaranteed to stay open source. Notable users include Wikipedia, Facebook and Google.
+
+MariaDB is developed as open source software and as a relational database it provides an SQL interface for accessing data. The latest versions of MariaDB also include GIS and JSON features.

+You can copy here your custom .sh, .sql or .sql.gz file so they are executed during the first boot of the image.

charts/mariadb/v5.0.9/templates/NOTES.txt

+
+Please be patient while the chart is being deployed
+
+Tip:
+
+  Watch the deployment status using the command: kubectl get pods -w --namespace {{ .Release.Namespace }} -l release={{ .Release.Name }}
+
+Services:
+
+  echo Master: {{ template "mariadb.fullname" . }}.{{ .Release.Namespace }}.svc.cluster.local:{{ .Values.service.port }}
+{{- if .Values.replication.enabled }}
+  echo Slave:  {{ template "slave.fullname" . }}.{{ .Release.Namespace }}.svc.cluster.local:{{ .Values.service.port }}
+{{- end }}
+
+Administrator credentials:
+
+  Username: root
+  Password : $(kubectl get secret --namespace {{ .Release.Namespace }} {{ template "mariadb.fullname" . }} -o jsonpath="{.data.mariadb-root-password}" | base64 --decode)
+
+To connect to your database:
+
+  1. Run a pod that you can use as a client:
+
+      kubectl run {{ template "mariadb.fullname" . }}-client --rm --tty -i --image  {{ template "mariadb.image" . }} --namespace {{ .Release.Namespace }} --command -- bash
+
+  2. To connect to master service (read/write):
+
+      mysql -h {{ template "mariadb.fullname" . }}.{{ .Release.Namespace }}.svc.cluster.local -uroot -p {{ .Values.db.name }}
+
+{{- if .Values.replication.enabled }}
+
+  3. To connect to slave service (read-only):
+
+      mysql -h {{ template "slave.fullname" . }}.{{ .Release.Namespace }}.svc.cluster.local -uroot -p {{ .Values.db.name }}
+{{- end }}
+
+To upgrade this helm chart:
+
+  1. Obtain the password as described on the 'Administrator credentials' section and set the 'rootUser.password' parameter as shown below:
+
+      ROOT_PASSWORD=$(kubectl get secret --namespace {{ .Release.Namespace }} {{ template "mariadb.fullname" . }} -o jsonpath="{.data.mariadb-root-password}" | base64 --decode)
+      helm upgrade {{ .Release.Name }} stable/mariadb --set rootUser.password=$ROOT_PASSWORD
