module: rax
short_description: create / delete an instance in Rackspace Public Cloud
description:
- creates / deletes a Rackspace Public Cloud instance and optionally
waits for it to be 'running'.
version_added: "1.2"
options:
auto_increment:
description:
- Whether or not to increment a single number with the name of the
created servers. Only applicable when used with the I(group) attribute
or meta key.
default: yes
choices:
- "yes"
- "no"
version_added: 1.5
boot_from_volume:
description:
- Whether or not to boot the instance from a Cloud Block Storage volume.
If C(yes) and I(image) is specified a new volume will be created at
boot time. I(boot_volume_size) is required with I(image) to create a
new volume at boot time.
default: "no"
choices:
- "yes"
- "no"
version_added: 1.9
boot_volume:
description:
- Cloud Block Storage ID or Name to use as the boot volume of the
instance
version_added: 1.9
boot_volume_size:
description:
- Size of the volume to create in Gigabytes. This is only required with
I(image) and I(boot_from_volume).
default: 100
version_added: 1.9
boot_volume_terminate:
description:
- Whether the I(boot_volume) or newly created volume from I(image) will
be terminated when the server is terminated
default: false
version_added: 1.9
config_drive:
description:
- Attach read-only configuration drive to server as label config-2
default: no
choices:
- "yes"
- "no"
version_added: 1.7
count:
description:
- number of instances to launch
default: 1
version_added: 1.4
count_offset:
description:
- number count to start at
default: 1
version_added: 1.4
disk_config:
description:
- Disk partitioning strategy
choices:
- auto
- manual
version_added: '1.4'
default: auto
exact_count:
description:
- Explicitly ensure an exact count of instances, used with
state=active/present. If specified as C(yes) and I(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 I(count)
additional servers will be added.
default: no
choices:
- "yes"
- "no"
version_added: 1.4
extra_client_args:
description:
- 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.
version_added: 1.6
extra_create_args:
description:
- 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.
version_added: 1.6
files:
description:
- Files to insert into the instance. remotefilename:localcontent
default: null
flavor:
description:
- flavor to use for the instance
default: null
group:
description:
- host group to assign to server, is also used for idempotent operations
to ensure a specific number of instances
version_added: 1.4
image:
description:
- image to use for the instance. Can be an C(id), C(human_id) or C(name).
With I(boot_from_volume), a Cloud Block Storage volume will be created
with this image
default: null
instance_ids:
description:
- list of instance ids, currently only used when state='absent' to
remove instances
version_added: 1.4
key_name:
description:
- key pair to use on the instance
default: null
aliases:
- keypair
meta:
description:
- A hash of metadata to associate with the instance
default: null
name:
description:
- Name to give the instance
default: null
networks:
description:
- The network to attach to the instances. If specified, you must include
ALL networks including the public and private interfaces. Can be C(id)
or C(label).
default:
- public
- private
version_added: 1.4
state:
description:
- Indicate desired state of the resource
choices:
- present
- absent
default: present
user_data:
description:
- Data to be uploaded to the servers config drive. This option implies
I(config_drive). Can be a file path or a string
version_added: 1.7
wait:
description:
- wait for the instance to be in state 'running' before returning
default: "no"
choices:
- "yes"
- "no"
wait_timeout:
description:
- how long before wait gives up, in seconds
default: 300
author:
- "Jesse Keating (@j2sol)"
- "Matt Martz (@sivel)"
notes:
- I(exact_count) can be "destructive" if the number of running servers in
the I(group) is larger than that specified in I(count). In such a case, the
I(state) is effectively set to C(absent) and the extra servers are deleted.
In the case of deletion, the returned data structure will have C(action)
set to C(delete), and the oldest servers in the group will be deleted.
