Data Structure for Creating ECSs

Contents

publicip Field Description

This field is used by the following APIs:
  • Creating ECSs /v1/{project_id}/cloudservers
Table 1 publicip field description

Parameter

Mandatory

Type

Description

id

No

String

Specifies the ID of the existing EIP assigned to the ECS to be created. The value is in UUID format.

Only EIPs in DOWN state can be assigned.

eip

No

Object

Specifies an EIP that will be automatically assigned to an ECS.

For details, see Table 3.

delete_on_termination

No

Boolean

Specifies whether the EIP is released when the ECS where the EIP is bound is deleted.

  • true: The EIP is released when the ECS is deleted.
  • false: The EIP is not released when the ECS is deleted.

The default value is false.

Either id or eip in the publicip field can be configured.

security_groups Field Description

This field is used by the following APIs:

Table 2 security_groups field description

Parameter

Mandatory

Type

Description

id

No

String

Specifies the ID of the security group to which an ECS is to be added. The configuration will take effect on the NICs of the ECS. You need to specify the ID of an existing security group in UUID format. Otherwise, the default security group will be used at the underlying layer.

eip Field Description

This field is used by the following APIs:
  • Creating ECSs /v1/{project_id}/cloudservers
Table 3 eip field description

Parameter

Mandatory

Type

Description

iptype

Yes

String

Specifies the EIP type.

For details about the enumerated values, see the publicip field in "Assigning an EIP" in Virtual Private Cloud API Reference.

bandwidth

Yes

Object

Specifies the bandwidth of an EIP.

For details, see bandwidth Field Description.

bandwidth Field Description

This field is used by the following APIs:
  • Creating ECSs /v1/{project_id}/cloudservers
Table 4 bandwidth field description

Parameter

Mandatory

Type

Description

size

Yes

Integer

Specifies the bandwidth size.

Specifies the bandwidth (Mbit/s). The value ranges from 1 to 300.

The specific range may vary depending on the configuration in each region. You can see the bandwidth range of each region on the management console.

The minimum increment for bandwidth adjustment varies depending on the bandwidth range.
  • The minimum increment is 1 Mbit/s if the allowed bandwidth ranges from 0 Mbit/s to 300 Mbit/s (with 300 Mbit/s included).
  • The minimum increment is 50 Mbit/s if the allowed bandwidth ranges from 300 Mbit/s to 1,000 Mbit/s (with 1,000 Mbit/s included).
  • The minimum increment is 500 Mbit/s if the allowed bandwidth is greater than 1,000 Mbit/s.
NOTE:

This parameter is mandatory when sharetype is set to PER and is optional when sharetype is set to WHOLE with an ID specified.

sharetype

Yes

String

Specifies the bandwidth sharing type.

Enumerated values: PER (indicates exclusive bandwidth) and WHOLE (indicates sharing)

chargemode

No

String

Specifies the bandwidth billing mode.

  • If the field value is traffic, the ECS is billed by traffic.
  • If the field value is others, creating the ECS will fail.

ipv6_bandwidth Field Description

This field is used by the following APIs:
  • Creating ECSs /v1/{project_id}/cloudservers
Table 5 ipv6_bandwidth field description

Parameter

Mandatory

Type

Description

id

No

String

Specifies the ID of an IPv6 bandwidth.

extendparam Field Description for Creating Disks

This field is used by the following APIs:

  • Creating ECSs /v1/{project_id}/cloudservers
Table 6 extendparam field description for creating disks

Parameter

Mandatory

Type

Description

resourceSpecCode

No

String

Specifies the code of the disk specifications, such as SATA, SAS, or SSD.

NOTE:

This field has been discarded.

resourceType

No

String

Specifies the resource type.

NOTE:

This field has been discarded.

snapshotId

No

String

Specifies the snapshot ID or ID of the original data disk contained in the full-ECS image.

Application scenarios:

This parameter is used if an ECS is created using a full-ECS image, and the image contains one or more data disks.

If you use a full-ECS image to create an ECS, the system automatically restores the data type and data from the data disks in the image. The snapshotId parameter allows you to specify the disk type for the original data disk after restoration.

NOTE:
  • You are advised to specify snapshotId for each original data disk.
  • If you are required to change a disk size, ensure that the changed disk size is greater than or equal to the size of the original data disk. Otherwise, restoring data of the original data disk will fail.
  • To set disk sharing, you need to specify the sharing attribute.
  • To set disk encryption, you need to specify the encryption attribute in the metadata field.

Working rules:

snapshotId uniquely identifies an original data disk contained in a full-ECS image. You can use snapshotId to obtain the information of the original data disk for data restoration.

Obtaining snapshotId through the management console:

Log in to the management console, choose Elastic Volume Service > Snapshot. Then, use the name of the original data disk to find the snapshot ID or the original disk ID.

Obtaining snapshotId through the API:

If you have obtained the full-ECS image ID, obtain the Cloud Backup and Recovery (CBR) or Cloud Server Backup Service (CSBS) backup ID associated with the full-ECS image ID by following the instructions provided in the API for querying image details.
  • If CBR backup is used, use the CBR backup ID to obtain the backup. The resource_id or snapshot_id contained in the children field in the response is the desired snapshotId. For details, see the API for "Querying a Specified Backup" in Cloud Backup and Recovery User Guide.
  • If CSBS backup is used, use the CSBS backup ID to obtain the backup. The source_volume_id or snapshot_id contained in the volume_backups field in the response is the desired snapshotId. For details, see the API for "Querying a Single Backup" in Cloud Server Backup Service User Guide.

extendparam Field Description for Creating ECSs
