Overview of this book

OpenStack is a widely popular platform for cloud computing. Applications that are built for this platform are resilient to failure and convenient to scale. This book, an update to our extremely popular OpenStack Essentials (published in May 2015) will help you master not only the essential bits, but will also examine the new features of the latest OpenStack release - Mitaka; showcasing how to put them to work straight away. This book begins with the installation and demonstration of the architecture. This book will tech you the core 8 topics of OpenStack. They are Keystone for Identity Management, Glance for Image management, Neutron for network management, Nova for instance management, Cinder for Block storage, Swift for Object storage, Ceilometer for Telemetry and Heat for Orchestration. Further more you will learn about launching and configuring Docker containers and also about scaling them horizontally. You will also learn about monitoring and Troubleshooting OpenStack.

Managing Cinder volumes in the web interface

Now that we have used the command line to manage Cinder volumes, let's take a look at using the web interface to accomplish the same thing:

  1. Log in to the web interface as your non-administrative user and select the Volumes submenu from the Compute menu.

  2. In the top-right corner, click on the Create Volume button.

  3. Fill in the name and size and click on Create Volume on the form:

  4. The web interface will update itself as the volume status changes. Once it becomes available, click on the More menu on the volume page and select Edit Attachments. In this dialog, the volume will be connected to the running instance. The following screenshot captures this step:

  5. In the Attachments dialog, select the instance to attach the volume to and click on the Attach Volume button, as shown in the following screenshot:

  6. Once again, the web interface will get updated as the status of the volume changes. The volume's status will become In-Use when it is attached to the instance...
