This repo was created to help you better understand the benefits you can get from Trident, for both the end-user & the admin teams. You will find several exercises, described in a step-by-step fashion, that you can use on the NetApp Lab-on-Demand or on your own environment.

The section has been tested with the Lab-on-Demand Using "Trident with Kubernetes and ONTAP v4.0" which comes with Trident 🔱 20.07.1 already installed on Kubernetes 1.18.6.

Most labs will be done by connecting with Putty to the RHEL3 host (root/Netapp1!).
I assume each scenario will be run in its own directory. Also, you will find a README file for each scenario.

Last, there are plenty of commands to write or copy/paste.
Try using some of the shortcuts you will find in the the Addenda0 !

- You may have seen that starting in November 2020, there are now limits on how many pull requests can be done on the Docker Hub.  
- As this lab was created with an _anonymous_ user, please read carefully the Addenda08 before starting this lab.
