NOTES:
The NFS Provisioner service has now been installed.
A storage class named 'nfs' has now been created
and is available to provision dynamic volumes.
You can use this storageclass by creating a `PersistentVolumeClaim` with the
correct storageClassName attribute. For example:
    ---
    kind: PersistentVolumeClaim
    apiVersion: v1
    metadata:
      name: test-dynamic-volume-claim
    spec:
      storageClassName: "nfs"
      accessModes:
        - ReadWriteOnce
      resources:
        requests:
          storage: 100Mi

NOTES:
MySQL can be accessed via port 3306 on the following DNS name from within your cluster:
mysqldb.default.svc.cluster.local
To get your root password run:
    MYSQL_ROOT_PASSWORD=$(kubectl get secret --namespace default mysqldb -o jsonpath="{.data.mysql-root-password}" | base64 --decode; echo)
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 mysqldb -p
To connect to your database directly from outside the K8s cluster:
    MYSQL_HOST=127.0.0.1
    MYSQL_PORT=3306
    # Execute the following command to route the connection:
    kubectl port-forward svc/mysqldb 3306
    mysql -h ${MYSQL_HOST} -P${MYSQL_PORT} -u root -p${MYSQL_ROOT_PASSWORD}
