module: cloudscale_volume
short_description: Manages volumes on the cloudscale.ch IaaS service
description:
- Create, attach/detach and delete volumes on the cloudscale.ch IaaS service.
- All operations are performed using the cloudscale.ch public API v1.
- "For details consult the full API documentation:
U(https://www.cloudscale.ch/en/api/v1)."
- A valid API token is required for all operations. You can create as many
tokens as you like using the cloudscale.ch control panel at
U(https://control.cloudscale.ch).
notes:
- Instead of the I(api_token) parameter the C(CLOUDSCALE_API_TOKEN) environment
variable can be used.
- To create a new volume at least the I(name) and I(size_gb) options
are required.
- A volume can be created and attached to a server in the same task.
version_added: 2.8
author: "Gaudenz Steinlin (@gaudenz)"
options:
state:
description:
- State of the volume.
default: present
choices: [ present, absent ]
name:
description:
- Name of the volume. Either name or UUID must be present to change an
existing volume.
uuid:
description:
- UUID of the volume. Either name or UUID must be present to change an
existing volume.
size_gb:
description:
- Size of the volume in GB.
type:
description:
- Type of the volume. Cannot be changed after creating the volume.
Defaults to ssd on volume creation.
choices: [ ssd, bulk ]
server_uuids:
description:
- UUIDs of the servers this volume is attached to. Set this to [] to
detach the volume. Currently a volume can only be attached to a
single server.
aliases: [ server_uuid ]
api_token:
description:
- cloudscale.ch API token.
- This can also be passed in the C(CLOUDSCALE_API_TOKEN) environment
variable.
api_timeout:
description:
- Timeout in seconds for calls to the cloudscale.ch API.
default: 30
