module: decort_disk
short_description: Manage Disks (virtualized storage resources) in DECORT cloud
description: >
This module can be used to create new disk in DECORT cloud platform, obtain or
modify its characteristics, and delete it.
version_added: "2.2"
author:
- Sergey Shubin <sergey.shubin@digitalenergy.online>
requirements:
- python >= 2.6
- PyJWT Python module
- requests Python module
- netaddr Python module
- decort_utils utility library (module)
- DECORT cloud platform version 3.6.1 or higher
notes:
- Environment variables can be used to pass selected parameters to the module, see details below.
- Specified Oauth2 provider must be trusted by the DECORT cloud controller on which JWT will be used.
- 'Similarly, JWT supplied in I(authenticator=jwt) mode should be received from Oauth2 provider trusted by
the DECORT cloud controller on which this JWT will be used.'
options:
account_id:
description:
- ID of the account, which owns this disk. This is the alternative to I(account_name) option.
- If both I(account_id) and I(account_name) specified, then I(account_name) is ignored.
default: 0
required: no
account_name:
description:
- 'Name of the account, which will own this disk.'
- 'This parameter is ignored if I(account_id) is specified.'
default: empty string
required: no
annotation:
description:
- Optional text description of this disk.
default: empty string
required: no
app_id:
description:
- 'Application ID for authenticating to the DECORT controller when I(authenticator=oauth2).'
- 'Required if I(authenticator=oauth2).'
- 'If not found in the playbook or command line arguments, the value will be taken from DECORT_APP_ID
environment variable.'
required: no
app_secret:
description:
- 'Application API secret used for authenticating to the DECORT controller when I(authenticator=oauth2).'
- This parameter is required when I(authenticator=oauth2) and ignored in other modes.
- 'If not found in the playbook or command line arguments, the value will be taken from DECORT_APP_SECRET
environment variable.'
required: no
authenticator:
description:
- Authentication mechanism to be used when accessing DECORT controller and authorizing API call.
default: jwt
choices: [ jwt, oauth2, legacy ]
required: yes
controller_url:
description:
- URL of the DECORT controller that will be contacted to manage the RG according to the specification.
- 'This parameter is always required regardless of the specified I(authenticator) type.'
required: yes
id:
description:
- `ID of the disk to manage. If I(id) is specified it is assumed, that this disk already
exists. In other words, you cannot create new disk by specifying its ID, use I(name)
when creating new disk.`
- `If non-zero I(id) is specified, then I(name), I(account_id) and I(account_name)
are ignored.`
default: 0
required: no
name:
description:
- `Name of the disk to manage. To manage disk by name you also need to specify either
I(account_id) or I(account_name).`
- If non-zero I(id) is specified, I(name) is ignored.
- `Note that the platform does not enforce uniqueness of disk names, so if more than one
disk with this name exists under the specified account, module will return the first
occurence.`
default: empty string
required: no
force_detach:
description:
- `By default it is not allowed to delete or destroy disk that is currently attached to a compute
instance (e.g. virtual machine or bare metal server). Set this argument to true to change this
behavior.`
- This argument is meaningful for I(state=absent) operations only and ignored otherwise.
default: false
required: no
jwt:
description:
- 'JWT (access token) for authenticating to the DECORT controller when I(authenticator=jwt).'
- 'This parameter is required if I(authenticator=jwt) and ignored for other authentication modes.'
- If not specified in the playbook, the value will be taken from DECORT_JWT environment variable.
required: no
oauth2_url:
description:
- 'URL of the oauth2 authentication provider to use when I(authenticator=oauth2).'
- 'This parameter is required when when I(authenticator=oauth2).'
- 'If not specified in the playbook, the value will be taken from DECORT_OAUTH2_URL environment variable.'
password:
description:
- 'Password for authenticating to the DECORT controller when I(authenticator=legacy).'
- 'This parameter is required if I(authenticator=legacy) and ignored in other authentication modes.'
- If not specified in the playbook, the value will be taken from DECORT_PASSWORD environment variable.
required: no
place_with:
description:
- `This argument can be used to simplify data disks creation along with a new compute, by placing
disks in the same storage, where corresponding OS image is deployed.`
- `Specify ID of an OS image, and the newly created disk will be provisioned from the same
storage, where this OS image is located. You may optionally specify I(pool) to control
actual disk placement within that storage, or leave I(pool=default) to let platform manage
it automatically.`
- This parameter is used when creating new disks and ignored for all other operations.
- This is an alternative to specifying I(sep_id).
default: 0
required: no
pool:
description:
- Name of the pool where to place new disk. Once disk is created, its pool cannot be changed.
- This parameter is used when creating new disk and igonred for all other operations.
default: empty string
required: no
sep_id:
description:
- `ID of the Storage Endpoint Provider (SEP) where to place new disk. Once disk is created,
its SEP cannot be changed.`
- `You may think of SEP as an identifier of a storage system connected to DECORT platform. There
may be several different storage systems and, consequently, several SEPs available to choose from.`
- This parameter is used when creating new disk and igonred for all other operations.
- See also I(place_with) for an alternative way to specify disk placement.
default: 0
required: no
size:
description:
- Size of the disk in GB. This parameter is mandatory when creating new disk.
- `If specified for an existing disk, and it is greater than current disk size, platform will try to resize
the disk on the fly. Downsizing disk is not allowed.`
required: no
limitIO:
description:
- Disk input / output limit, used to limit the speed of interaction with the disk.
required: no
type:
description:
- Type of the disk.
- `Disks can be of the following types: "D"-Data, "B"-Boot, "T"-Tmp.`
default: "D"
required: no
state:
description:
- Specify the desired state of the disk at the exit of the module.
- 'If desired I(state=present):'
- ' - Disk does not exist or is in [DESTROYED, PURGED] states, create new disk according to the specifications.'
- ' - Disk is in DELETED state, restore it and change size if necessary.'
- ' - Disk is in one of [CREATED, ASSIGNED] states, do nothing.'
- ' - Disk in any other state, abort with an error.'
- 'If desired I(state=absent):'
- ' - Disk is in one of [CREATED, ASSIGNED, DELETED] states, destroy it.'
- ' - Disk not found or in [DESTROYED, PURGED] states, do nothing.'

- If not specified in the playbook, the value will be taken from DECORT_USER environment variable.
required: no
verify_ssl:
description:
- 'Controls SSL verification mode when making API calls to DECORT controller. Set it to False if you
want to disable SSL certificate verification. Intended use case is when you run module in a trusted
environment that uses self-signed certificates. Note that disabling SSL verification in any other
scenario can lead to security issues, so please know what you are doing.'
default: True
required: no
workflow_callback:
description:
- 'Callback URL that represents an application, which invokes this module (e.g. up-level orchestrator or
end-user portal) and may except out-of-band updates on progress / exit status of the module run.'
- API call at this URL will be used to relay such information to the application.
- 'API call payload will include module-specific details about this module run and I(workflow_context).'
required: no
workflow_context:
description:
- 'Context data that will be included into the payload of the API call directed at I(workflow_callback) URL.'
- 'This context data is expected to uniquely identify the task carried out by this module invocation so
that up-level orchestrator could match returned information to the its internal entities.'
required: no
