CHPC Cloud Resources
How can I use an OpenStack cloud?
As an OpenStack cloud end user, you can provision your own resources within the limits set by cloud administrators.
The examples in this guide show you how to perform tasks by using the following methods:
- OpenStack dashboard: Use this web-based graphical interface, code named horizon, to view, create, and manage resources.
- OpenStack command-line clients: Each core OpenStack project has a command-line client that you can use to run simple commands to view, create, and manage resources in a cloud and automate tasks by using scripts.
Introduction - Volumes
Openstack volumes are logical block devices that can be attached to a single instance to provide a persistent location for data storage. Unlike a virtual machine's local disk which is destroyed along with the VM, volumes are decoupled from instances so that they may be attached and reattached to different instances. This allows you to create & destroy instances as you see fit while maintaining a persistent store for data.
1. Create Volume.
From the Openstack dashboard, click Compute > Volumes > Create Volume, fill out the form by providing a meaningful name, description and size. Once this is done, click ‘Create Volume’. Your volume will be created and you can move on to the next step, ‘Attach a volume to an instance’.
2. Attach a volume to an Instance.
3. Identify A volume within Instance.
4. Formatting the Volume.
