Instance Attribute Details

#address ⇒ Hash<String, Array[Hash]> (readonly)

Returns IP addresses allocated for server by network.

Examples:

{ 
   "public" => [
        {"version"=>4, "addr"=>"166.78.105.63"}, 
        {"version"=>6, "addr"=>"2001:4801:7817:0072:0fe1:75e8:ff10:61a9"}
               ], 
  "private"=> [{"version"=>4, "addr"=>"10.177.18.209"}]
}

Returns:

  • (Hash<String, Array[Hash]>) —

    IP addresses allocated for server by network

attribute :addresses

#bandwidth ⇒ Array (readonly)

Returns The amount of bandwidth used for the specified audit period.

Returns:

  • (Array) —

    The amount of bandwidth used for the specified audit period.

# File 'lib/fog/rackspace/models/compute_v2/server.rb', line 111

attribute :bandwidth, :aliases => 'rax-bandwidth:bandwidth'

#created ⇒ String (readonly)

Returns The time stamp for the creation date.

Returns:

  • (String) —

    The time stamp for the creation date.



35
 
# File 'lib/fog/rackspace/models/compute_v2/server.rb', line 35

attribute :created

#disk_config ⇒ String<AUTO, MANUAL>

The disk configuration value.

* AUTO -   The server is built with a single partition the size of the target flavor disk. The file system is automatically adjusted to fit the entire partition. 
           This keeps things simple and automated. AUTO is valid only for images and servers with a single partition that use the EXT3 file system. 
           This is the default setting for applicable Rackspace base images.

* MANUAL - The server is built using whatever partition scheme and file system is in the source image. If the target flavor disk is larger, 
           the remaining disk space is left unpartitioned. This enables images to have non-EXT3 file systems, multiple partitions, 
           and so on, and enables you to manage the disk configuration.

Returns:

  • (String<AUTO, MANUAL>) —

    The disk configuration value.

#host Id(Id) ⇒ Object (readonly)

The host Id. The compute provisioning algorithm has an anti-affinity property that attempts to spread customer VMs across hosts. Under certain situations, VMs from the same customer might be placed on the same host. hostId represents the host your server runs on and can be used to determine this scenario if it is relevant to your application. HostId is unique per account and is not globally unique.

Note:

Rescue mode is only guaranteed to be active for 90 minutes.

#resize(flavor_id) ⇒ Boolean

Note:

All resizes are automatically confirmed after 24 hours if you do not explicitly confirm or revert the resize.

Resize existing server to a different flavor, in essence, scaling the server up or down. The original server is saved for a period of time to allow rollback if there is a problem. All resizes should be tested and explicitly confirmed, at which time the original server is removed. All resizes are automatically confirmed after 24 hours if they are not confirmed or reverted.

  • Status Transition:
