module: decort_osimage
short_description: Locate OS image in DCORT cloud by its name and return image ID
description: >
This module can be used to obtain image ID of an OS image in DECORT cloud to use with subsequent calls to
decort_vm module for batch VM provisioning. It will speed up VM creation and save a bunch of extra calls to
DECORT cloud controller on each VM creation act.
Note that this module is effectively an information provisioner. It is not designed to and does not manage
nor change state of OS image (or any other) objects in DECORT cloud.
version_added: "2.2"
author:
- Sergey Shubin <sergey.shubin@digitalenergy.online>
requirements:
- python >= 2.6
- PyJWT module
- requests module
- decort_utils utility library (module)
- DECORT cloud platform version 3.4.0 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:
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 obtain OS image details.
- 'This parameter is always required regardless of the specified I(authenticator) type.'
required: yes
image_name:
description:
- Name of the OS image to use. Module will return the ID of this image.
- 'The specified image name will be looked up in the target DECORT controller and error will be generated if
no matching image is found.'
required: yes
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
pool:
description:
- 'Name of the storage pool, where the image should be found.'
- 'Omit this option if no matching by pool name is required. The first matching image will be returned."
required: no
sep_id:
description:
- 'ID of the SEP (Storage End-point Provider), where the image should be found.'
- 'Omit this option if no matching by SEP ID is required. The first matching image will be returned."
required: no
account_name:
description:
- 'Name of the account for which the specified OS image will be looked up.'
- 'This parameter is required for listing OS images.'
required: yes
user:
description:
- 'Name of the legacy user for authenticating to the DECORT controller when I(authenticator=legacy).'
- 'This parameter is required when I(authenticator=legacy) and ignored for other authentication modes.'
- If not specified in the playbook, the value will be taken from DECORT_USER environment variable.
required: no
vdc_id:
description:
- ID of the VDC to limit the search of the OS image to.
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
