Create a volume

This call creates a new volume. Currently, volumes may be created using three types of cloud storage repository:

Amazon Web Services' (AWS) S3 buckets
Google Cloud Storage (GCS) buckets
Other types of cloud storage, through an S3-compatible API (read-only). This cloud storage type requires an additional API layer that the storage employs, which must use the same "language" as the AWS S3 API.

📘
If your are using a cloud storage provider other than Amazon Web Services S3 or Google Cloud Storage, please make sure you have met the following requirements:

There is an additional API layer implemented on your cloud storage, compatible with the AWS S3 API. This means that you need to use an additional service or software on top of your storage, that will emulate the behavior and interaction of AWS S3 storage.

You or your cloud storage administrator can provide S3-compatible storage endpoint and credentials that are required to connect the storage to CAVATICA. These should be available for creation or obtaining when you have met the previous prerequisite.

Header Fields

Key	Description of value
`X-SBG-Auth-Token` required	Your CAVATICA authentication token.
`Content-type` required	`application/json`

Request body

In the body, you should enter a list of key-value pairs. The keys and the values they take are described in the following table.

Key	Data type of value	Description of value
`name` required	String	The name of the volume. It must be unique from all other volumes for this user.
`access_mode`	String	Signifies whether this volume should be used for read-write (`"RW"`) or read-only (`"RO"`) operations. The access mode is consulted independently of the credentials granted to Seven Bridges when the volume was created, so it is possible to use a read-write credentials to register both read-write and read-only volumes using it. default: `"RW"`
`description`	String	An optional description of this volume.
`service` required	Object	This object should contain the information about the cloud service that this volume represents. See the `service` object section below for an explanation of its structure.

The `service` object

Key	Data type of value	Description of value
`type`	string	The type of cloud service supported. Currently the only valid values are `"s3"` for Amazon Web Services or an S3-compatible endpoint and `"gcs"` for Google Cloud Storage.
`prefix`	String	A service-specific prefix to prepend to all objects created in this volume. If the service supports folders, and this prefix includes them, the API will attempt to create any missing folders when it outputs a file. default: `""`
`bucket` applies to type: `s3` and `gcs` required	String	The name of the bucket you wish to register as a volume.
`root_url` default: https://s3.amazonaws.com for `s3`, https://www.googleapis.com/ for `gcs`, or a custom endpoint if you are connecting cloud storage through an S3-compatible endpoint.	String	Cloud provider API endpoint to use when accessing this bucket. For a list of AWS-supported endpoints, see AWS Regions and Endpoints.
`credentials`	Object	Contains credentials for the underlying cloud provider. AWS IAM user, or S3-compatible endpoint: `access-key-id` `secret_access-key` For Google Cloud Storage, these credentials are: `client_email` * `private_key`
`access_key_id` applies to type: `s3` required	String	AWS access key ID of the IAM user shared with Seven Bridges to access this bucket.
`secret_access_key` applies to type: `s3` required	String	AWS secret access key of the IAM user shared with Seven Bridges to access this bucket.
`client_email` applies to type: `gcs` required	String	Google Cloud Platform user email.
`private_key` applies to type: `gcs` required	String	Google Cloud Platform private key.
`properties`	Object	Contains properties of specific service.
`sse_algorithm` applies to type: `s3`	String	Use default AES256 server-side encryption or AWS KMS encryption when writing to this bucket. Can be: AES256 (default) aws:kms default: AES256
`sse_aws_kms_key_id` applies to type: `s3`	String	If AWS KMS encryption is used, this should be set to the required KMS key. If not set and `aws:kms` is set as `sse_algorithm`, default KMS key is used.

Note that you cannot view volumes that you have created via the visual interface. However, you can see all your volumes by making the call to list volumes.
