rax – create / delete an instance in Rackspace Public Cloud

Synopsis

  • creates / deletes a Rackspace Public Cloud instance and optionally waits for it to be ‘running’.

Requirements

The below requirements are needed on the host that executes this module.

  • python >= 2.6

  • pyrax

Parameters

Parameter Choices/Defaults Comments
api_key
-
Rackspace API key, overrides credentials.

aliases: password
auth_endpoint
-
Default:
"https://identity.api.rackspacecloud.com/v2.0/"
The URI of the authentication service.
auto_increment
boolean
    Choices:
  • no
  • yes ←
Whether or not to increment a single number with the name of the created servers. Only applicable when used with the group attribute or meta key.
boot_from_volume
boolean
    Choices:
  • no ←
  • yes
Whether or not to boot the instance from a Cloud Block Storage volume. If yes and image is specified a new volume will be created at boot time. boot_volume_size is required with image to create a new volume at boot time.
boot_volume
-
Cloud Block Storage ID or Name to use as the boot volume of the instance
boot_volume_size
-
Default:
100
Size of the volume to create in Gigabytes. This is only required with image and boot_from_volume.
boot_volume_terminate
boolean
    Choices:
  • no ←
  • yes
Whether the boot_volume or newly created volume from image will be terminated when the server is terminated
config_drive
boolean
    Choices:
  • no ←
  • yes
Attach read-only configuration drive to server as label config-2
count
-
Default:
1
number of instances to launch
count_offset
-
Default:
1
number count to start at
credentials
-
File to find the Rackspace credentials in. Ignored if api_key and username are provided.

aliases: creds_file
disk_config
-
    Choices:
  • auto ←
  • manual
Disk partitioning strategy
env
-
Environment as configured in ~/.pyrax.cfg, see
exact_count
boolean
    Choices:
  • no ←
  • yes
Explicitly ensure an exact count of instances, used with state=active/present. If specified as yes and count is less than the servers matched, servers will be deleted to match the count. If the number of matched servers is fewer than specified in count additional servers will be added.
extra_client_args
-
A hash of key/value pairs to be used when creating the cloudservers client. This is considered an advanced option, use it wisely and with caution.
extra_create_args
-
A hash of key/value pairs to be used when creating a new server. This is considered an advanced option, use it wisely and with caution.
files
-
Files to insert into the instance. remotefilename:localcontent
flavor
-
flavor to use for the instance
group
-
host group to assign to server, is also used for idempotent operations to ensure a specific number of instances
identity_type
-
Default:
"rackspace"
Authentication mechanism to use, such as rackspace or keystone.
image
-
image to use for the instance. Can be an id, human_id or name. With boot_from_volume, a Cloud Block Storage volume will be created with this image
instance_ids
-
list of instance ids, currently only used when state='absent' to remove instances
key_name
-
key pair to use on the instance

aliases: keypair
meta
-
A hash of metadata to associate with the instance
name
-
Name to give the instance
networks
-
Default:
["public", "private"]
The network to attach to the instances. If specified, you must include ALL networks including the public and private interfaces. Can be id or label.
region
-
Default:
"DFW"
Region to create an instance in.
state
-
    Choices:
  • present ←
  • absent
Indicate desired state of the resource
tenant_id
-
The tenant ID used for authentication.
tenant_name
-
The tenant name used for authentication.
user_data
-
Data to be uploaded to the servers config drive. This option implies config_drive. Can be a file path or a string
username
-
Rackspace username, overrides credentials.
validate_certs
boolean
    Choices:
  • no
  • yes
Whether or not to require SSL validation of API endpoints.

aliases: verify_ssl
wait
boolean
    Choices:
  • no ←
  • yes
wait for the instance to be in state 'running' before returning
wait_timeout
-
Default:
300
how long before wait gives up, in seconds

Notes

Note

  • exact_count can be “destructive” if the number of running servers in the group is larger than that specified in count. In such a case, the state is effectively set to absent and the extra servers are deleted. In the case of deletion, the returned data structure will have action set to delete, and the oldest servers in the group will be deleted.

  • The following environment variables can be used, RAX_USERNAME, RAX_API_KEY, RAX_CREDS_FILE, RAX_CREDENTIALS, RAX_REGION.

  • RAX_CREDENTIALS and RAX_CREDS_FILE points to a credentials file appropriate for pyrax. See https://github.com/rackspace/pyrax/blob/master/docs/getting_started.md#authenticating

  • RAX_USERNAME and RAX_API_KEY obviate the use of a credentials file

  • RAX_REGION defines a Rackspace Public Cloud region (DFW, ORD, LON, …)
