Knife Rackspace ↑

DESCRIPTION: ↑

This is the official Opscode Knife plugin for Rackspace. This plugin gives knife the ability to create, bootstrap, and manage servers on the Rackspace Cloud.

INSTALLATION: ↑

Be sure you are running the latest version Chef. Versions earlier than 0.10.0 don’t support plugins:

gem install chef

This plugin is distributed as a Ruby Gem. To install it, run:

gem install knife-rackspace

Depending on your system’s configuration, you may need to run this command with root privileges.

CONFIGURATION: ↑

In order to communicate with the Rackspace Cloud API you will have to tell Knife about your Username and API Key. The easiest way to accomplish this is to create some entries in your knife.rb file:

knife[:rackspace_api_username] = "Your Rackspace API username"
knife[:rackspace_api_key] = "Your Rackspace API Key"

If your knife.rb file will be checked into a SCM system (ie readable by others) you may want to read the values from environment variables:

knife[:rackspace_api_username] = "#{ENV['RACKSPACE_USERNAME']}"
knife[:rackspace_api_key] = "#{ENV['RACKSPACE_API_KEY']}"

You also have the option of passing your Rackspace API Username/Key into the individual knife subcommands using the -A (or --rackspace-api-username) -K (or --rackspace-api-key) command options

# provision a new 1GB Ubuntu 10.04 webserver
knife rackspace server create -I 112 -f 3 -A 'Your Rackspace API username' -K "Your Rackspace API Key" -r 'role[webserver]'

This plugin also has support for authenticating against an alternate API Auth URL. This is useful if you are a Rackspace Cloud UK user or OpenStack early adopter. Here is an example of configuring knife for Rackspace Cloud UK:

knife[:rackspace_api_auth_url] = "lon.auth.api.rackspacecloud.com"

Additionally the following options may be set in your ‘knife.rb`:

  • flavor

  • image

  • distro

  • template_file

SUBCOMMANDS: ↑

This plugin provides the following Knife subcommands. Specific command options can be found by invoking the subcommand with a --help flag

knife rackspace server create ↑

Provisions a new server in the Rackspace Cloud and then perform a Chef bootstrap (using the SSH protocol). The goal of the bootstrap is to get Chef installed on the target system so it can run Chef Client with a Chef Server. The main assumption is a baseline OS installation exists (provided by the provisioning). It is primarily intended for Chef Client systems that talk to a Chef server. By default the server is bootstrapped using the ubuntu10.04-gems template. This can be overridden using the -d or --template-file command options.

knife rackspace server delete ↑

Deletes an existing server in the currently configured Rackspace Cloud account by the server/instance id. You can find the instance id by entering ‘knife rackspace server list’. Please note - this does not delete the associated node and client objects from the Chef server.

knife rackspace server list ↑

Outputs a list of all servers in the currently configured Rackspace Cloud account. Please note - this shows all instances associated with the account, some of which may not be currently managed by the Chef server.

knife rackspace flavor list ↑

Outputs a list of all available flavors (available hardware configuration for a server) available to the currently configured Rackspace Cloud account. Each flavor has a unique combination of disk space, memory capacity and priority for CPU time. This data can be useful when choosing a flavor id to pass to the knife rackspace server create subcommand.

knife rackspace image list ↑

Outputs a list of all available images available to the currently configured Rackspace Cloud account. An image is a collection of files used to create or rebuild a server. Rackspace provides a number of pre-built OS images by default. This data can be useful when choosing an image id to pass to the knife rackspace server create subcommand.
