Getting Started With Rackspace

Rackspace is a major public cloud platform and is one of the core platforms that Salt Cloud has been built to support.

  • Using the old format, set up the cloud configuration at /etc/salt/cloud:
# Set the location of the salt-master
#
minion:
  master: saltmaster.example.com

# Configure Rackspace using the OpenStack plugin
#
OPENSTACK.identity_url: 'https://identity.api.rackspacecloud.com/v2.0/tokens'
OPENSTACK.compute_name: cloudServersOpenStack
OPENSTACK.protocol: ipv4

# Set the compute region:
#
OPENSTACK.compute_region: DFW

# Configure Rackspace authentication credentials
#
OPENSTACK.user: myname
OPENSTACK.tenant: 123456
OPENSTACK.apikey: xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
  • Using the new format, set up the cloud configuration at /etc/salt/cloud.providers or /etc/salt/cloud.providers.d/rackspace.conf:
my-rackspace-config:
  # Set the location of the salt-master
  #
  minion:
    master: saltmaster.example.com

  # Configure Rackspace using the OpenStack plugin
  #
  identity_url: 'https://identity.api.rackspacecloud.com/v2.0/tokens'
  compute_name: cloudServersOpenStack
  protocol: ipv4

  # Set the compute region:
  #
  compute_region: DFW

  # Configure Rackspace authentication credentials
  #
  user: myname
  tenant: 123456
  apikey: xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx

  provider: openstack

Compute Region

Rackspace currently has five compute regions which may be used:

DFW -> Dallas/Forth Worth
ORD -> Chicago
SYD -> Sydney
LON -> London
IAD -> Northern Virginia

Note: Currently the LON region is only avaiable with a UK account, and UK accounts cannot access other regions

Authentication

The user is the same user as is used to log into the Rackspace Control Panel. The tenant and apikey can be found in the API Keys area of the Control Panel. The apikey will be labeled as API Key (and may need to be generated), and tenant will be labeled as Cloud Account Number.

An initial profile can be configured in /etc/salt/cloud.profiles or /etc/salt/cloud.profiles.d/rackspace.conf:

  • Using the old cloud configuration format:
openstack_512:
    provider: openstack
    size: 512MB Standard Instance
    image: Ubuntu 12.04 LTS (Precise Pangolin)
  • Using the new cloud configuration format and the example configuration from above:
openstack_512:
    provider: my-rackspace-config
    size: 512MB Standard Instance
    image: Ubuntu 12.04 LTS (Precise Pangolin)

To instantiate a machine based on this profile:

# salt-cloud -p openstack_512 myinstance

This will create a virtual machine at Rackspace with the name myinstance. This operation may take several minutes to complete, depending on the current load at the Rackspace data center.

Once the instance has been created with salt-minion installed, connectivity to it can be verified with Salt:

# salt myinstance test.ping

RackConnect Environments

Rackspace offers a hybrid hosting configuration option called RackConnect that allows you to use a physical firewall appliance with your cloud servers. When this service is in use the public_ip assigned by nova will be replaced by a NAT ip on the firewall. For salt-cloud to work properly it must use the newly assigned “access ip” instead of the Nova assigned public ip. You can enable that capability by adding this to your profiles:

openstack_512:
    provider: my-openstack-config
    size: 512MB Standard Instance
    image: Ubuntu 12.04 LTS (Precise Pangolin)
    rackconnect: True

Managed Cloud Environments

Rackspace offers a managed service level of hosting. As part of the managed service level you have the ability to choose from base of lamp installations on cloud server images. The post build process for both the base and the lamp installations used Chef to install things such as the cloud monitoring agent and the cloud backup agent. It also takes care of installing the lamp stack if selected. In order to prevent the post installation process from stomping over the bootstrapping you can add the below to your profiles.

openstack_512:
    provider: my-rackspace-config
    size: 512MB Standard Instance
    image: Ubuntu 12.04 LTS (Precise Pangolin)
    managedcloud: True

First and Next Generation Images

Rackspace provides two sets of virtual machine images, first and next generation. As of 0.8.9 salt-cloud will default to using the next generation images. To force the use of first generation images, on the profile configuration please add:

FreeBSD-9.0-512:
  provider: my-rackspace-config
  size: 512MB Standard Instance
  image: FreeBSD 9.0
  force_first_gen: True
