OpenStack

Warning: This page is currently under construction. Information may not be ready for users.

OpenStack is an open-source cloud stack that is currently running on Red Cloud. Also, for more information, see the Official Documentation for OpenStack. If you are looking for information on how to migrate an instance from Eucalyptus to OpenStack, please see OpenStack Migration.

Using the OpenStack Web Interface (Horizon)

There are two ways to manage Red Cloud resources:

1. OpenStack Web Interface
2. OpenStack CLI

Most users will use the OpenStack Web Interface (called Horizon). This web-based interface can be used to manage instances and volumes. For Red Cloud Linux Instances, however, some users may choose to use the OpenStack CLI. This section focuses on the OpenStack Web Interface.

Logging In

Log in to the OpenStack Web Interface to create and manage Red Cloud resources. There are two ways to login:

• CAC Account

Enter cac as the Domain and your CAC username and password, not your Cornell NetID

• Globus Auth

You can use the Authenticate using drop-down to switch between the two options. Neither option requires you to enter a project ID, rather you can switch between the projects you are on once logged in.

Using CAC Account

To authenticate using your CAC account, you must fill in the following information:

Domain - enter cac here

User Name and Password - enter your https://www.cac.cornell.edu/services/myacct.aspx CAC username] and password, not your Cornell NetID

Using Globus Auth

If they can’t log in with globus, they may not have linked their Cornell account (the one on the project) to their globus account

Overview Page

The Overview page is the first place you will be taken upon logging into Red Cloud.

• Provides easy access to main functions, but many functions can be accessed from other pages
• Before creating an instance, you will need to:
  • Create a key pair - for authentication when you log in the first time
  • Create a security group - defines allowable types of port access for an instance
  • Optional: Create and Attach a Volume (can also be done when launching an Instance)
  • Optional: Set up a network - ... TODO
  • TODO - figure out if this should be included: Optional: Allocate an elastic IP address - a fixed IP address that can be assigned to an instance

Key Pairs

This is obviously visible along the top bar when compute is selected: Key Pairs

Can create or upload.

Can't create or upload during Instance setup.

Security Groups

Getting to this is not obvious: Security Groups

Can't create one during Instance setup.

Instances

Launch an Instance

1. Create Key Pair 2.
