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

Comments

api_key

aliases: password

string

Rackspace API key, overrides credentials.

auth_endpoint

string

The URI of the authentication service.

If not specified will be set to https://identity.api.rackspacecloud.com/v2.0/

auto_increment

boolean

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.

Choices:

  • false

  • true ← (default)

boot_from_volume

boolean

Whether or not to boot the instance from a Cloud Block Storage volume. If true 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.

Choices:

  • false ← (default)

  • true

boot_volume

string

Cloud Block Storage ID or Name to use as the boot volume of the instance

boot_volume_size

integer

Size of the volume to create in Gigabytes. This is only required with image and boot_from_volume.

Default: 100

boot_volume_terminate

boolean

Whether the boot_volume or newly created volume from image will be terminated when the server is terminated

Choices:

  • false ← (default)

  • true

config_drive

boolean

Attach read-only configuration drive to server as label config-2

Choices:

  • false ← (default)

  • true

count

integer

number of instances to launch

Default: 1

count_offset

integer

number count to start at

Default: 1

credentials

aliases: creds_file

path

File to find the Rackspace credentials in. Ignored if api_key and username are provided.

disk_config

string

Disk partitioning strategy

If not specified it will assume the value auto.

Choices:

  • "auto"

  • "manual"

env

string

Environment as configured in ~/.pyrax.cfg, see https://github.com/rackspace/pyrax/blob/master/docs/getting_started.md#pyrax-configuration.

exact_count

boolean

Explicitly ensure an exact count of instances, used with state=active/present. If specified as true 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.

Choices:

  • false ← (default)

  • true

extra_client_args

dictionary

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.

Default: {}

extra_create_args

dictionary

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.

Default: {}

files

dictionary

Files to insert into the instance. remotefilename:localcontent

Default: {}

flavor

string

flavor to use for the instance

group

string

host group to assign to server, is also used for idempotent operations to ensure a specific number of instances

identity_type

string

Authentication mechanism to use, such as rackspace or keystone.

Default: "rackspace"

image

string

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 / elements=string

list of instance ids, currently only used when state=’absent’ to remove instances

key_name

aliases: keypair

string

key pair to use on the instance

meta

dictionary

A hash of metadata to associate with the instance

Default: {}

name

string

Name to give the instance

networks

list / elements=string

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.

Default: ["public", "private"]

region

string

Region to create an instance in.

state

string

Indicate desired state of the resource

Choices:

  • "present" ← (default)

  • "absent"

tenant_id

string

The tenant ID used for authentication.

tenant_name

string

The tenant name used for authentication.

user_data

string

Data to be uploaded to the servers config drive. This option implies config_drive. Can be a file path or a string

username

string

Rackspace username, overrides credentials.

validate_certs

aliases: verify_ssl

boolean

Whether or not to require SSL validation of API endpoints.

Choices:

  • false

  • true

wait

boolean

wait for the instance to be in state ‘running’ before returning

Choices:

  • false ← (default)

  • true

wait_timeout

integer

how long before wait gives up, in seconds

Default: 300

Attributes

Attribute

Support

Description

check_mode

Support: none

Can run in check_mode and return changed status prediction without modifying target.

diff_mode

Support: none

Will return details on what has changed (or possibly needs changing in check_mode), when in diff mode.

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, …)
