MySQL can be accessed via port 3306 on the following DNS name from within your cluster:
{{ template "mysql.fullname" . }}.{{ .Release.Namespace }}.svc.cluster.local

{{- if .Values.mysqlx.port.enabled }}
Connection to the X protocol of MySQL can be done via 33060 on the following DNS name from within your cluster:
{{ template "mysql.fullname" . }}.{{ .Release.Namespace }}.svc.cluster.local
{{- end }}

{{- if .Values.existingSecret }}
If you have not already created the mysql password secret:

   kubectl create secret generic {{ .Values.existingSecret }} --namespace {{ .Release.Namespace }} --from-file=./mysql-root-password --from-file=./mysql-password
{{ else }}

To get your root password run:

    MYSQL_ROOT_PASSWORD=$(kubectl get secret --namespace {{ .Release.Namespace }} {{ template "mysql.fullname" . }} -o jsonpath="{.data.mysql-root-password}" | base64 --decode; echo)
{{- end }}

To connect to your database:

1. Run an Ubuntu pod that you can use as a client:

    kubectl run -i --tty ubuntu --image=ubuntu:16.04 --restart=Never -- bash -il

2. Install the mysql client:

    $ apt-get update && apt-get install mysql-client -y

3. Connect using the mysql cli, then provide your password:
    $ mysql -h {{ template "mysql.fullname" . }} -p

To connect to your database directly from outside the K8s cluster:
    {{- if contains "NodePort" .Values.service.type }}
    MYSQL_HOST=$(kubectl get nodes --namespace {{ .Release.Namespace }} -o jsonpath='{.items[0].status.addresses[0].address}')
    MYSQL_PORT=$(kubectl get svc --namespace {{ .Release.Namespace }} {{ template "mysql.fullname" . }} -o jsonpath='{.spec.ports[0].nodePort}')

    {{- else if contains "ClusterIP" .Values.service.type }}
    MYSQL_HOST=127.0.0.1
    MYSQL_PORT={{ .Values.service.port }}

    # Execute the following command to route the connection:
    kubectl port-forward svc/{{ template "mysql.fullname" . }} {{ .Values.service.port }}

    {{- end }}

    mysql -h ${MYSQL_HOST} -P${MYSQL_PORT} -u root -p${MYSQL_ROOT_PASSWORD}
