Create a ConfigMap
Create a ConfigMap in the hive Namespace called honey-config.

Store the following data in the ConfigMap:
```
honey.cfg: |
  There is always money in the honey stand!
```
Challenge

Create a Secret
Create a Secret called hive-sec in the hive Namespace.

Store the following value in the Secret:
```
hiveToken: secretToken!

Note that you will need to base64-encode the secretToken! value.
Challenge

Modify the Deployment To Use the ConfigMap and Secret Data

In the hive Namespace, there is a Deployment called hive-mgr. Edit this Deployment so that the container is able to access the data from the ConfigMap and Secret.

For the Secret, provide the value of the hiveToken key to the container as an environment variable called TOKEN.

For the ConfigMap, load the data from the honey.cfg key using a mounted volume. The data should ultimately be accessible by the container at the path /config/honey.cfg.
