Creating an AS Configuration¶

Function¶

This API is used to create an AS configuration.

An AS configuration is a template specifying specifications for the instances to be added to an AS group.
The AS configuration is decoupled from the AS group. An AS configuration can be used by multiple AS groups.
Up to 100 AS configurations can be created for each user.

**Table 1** Parameter description¶
Parameter	Mandatory	Type	Description
project_id	Yes	String	Specifies the project ID.

Request Message¶

Request parameters

**Table 2** Request parameters¶
Parameter	Mandatory	Type	Description
scaling_configuration_name	Yes	String	Specifies the AS configuration name. The name contains only letters, digits, underscores (_), and hyphens (-), and cannot exceed 64 characters.
instance_config	Yes	Object	Specifies the ECS configuration. For details, see Table 3.

**Table 3** **instance_config** field description¶
Parameter	Mandatory	Type	Description
instance_id	No	String	Specifies the ECS ID. When you want to create an AS configuration from an ECS, specify this parameter. In this case, the flavorRef, imageRef, disk, and security_groups fields do not take effect. If the instance_id field is not specified, flavorRef, imageRef, and disk fields are mandatory.
flavorRef	No	String	Specifies the ECS flavor ID. A maximum of 10 flavors can be selected. Use a comma (,) to separate multiple flavor IDs. You can obtain an ECS flavor ID from the API for querying details about flavors and extended flavor information.
imageRef	No	String	Specifies the image ID. Its value is the same as that of image_id for specifying the image selected during ECS creation. You can obtain an image ID by calling the IMS API for querying images.
disk	No	Array of disk objects	Specifies the disk group information. System disks are mandatory and data disks are optional. For details, see Table 4.
key_name	Yes	String	Specifies the name of the SSH key pair used to log in to the ECS.
personality	No	Array of personality objects	Specifies information about the injected file. Only text files can be injected. A maximum of five files can be injected at a time and the maximum size of each file is 1 KB. For details, see Table 6.
public_ip	No	public_ip object	Specifies the EIP of the ECS. The EIP can be configured in two ways. For details, see Table 7. Do not use an EIP. In this case, this parameter is unavailable. Automatically assign an EIP. You need to specify the information about the new EIP.
user_data	No	String	Specifies the user data to be injected during the ECS creation process. Text, text files, and gzip files can be injected. Constraints: The content to be injected must be encoded with base64. The maximum size of the content to be injected (before encoding) is 32 KB. Examples: Linux #! /bin/bash echo user_test >> /home/user.txt Windows rem cmd echo 111 > c:\aaa.txt
metadata	No	metadata object	Specifies the ECS metadata. For details, see Table 10.
security_groups	No	Array of security_groups objects	Specifies security groups. For details, see Table 11. If the security group is specified both in the AS configuration and AS group, scaled ECS instances will be added to the security group specified in the AS configuration. If the security group is not specified in either of them, scaled ECS instances will be added to the default security group. For your convenience, you are advised to specify the security group in the AS configuration.
market_type	No	String	This parameter is reserved.

**Table 4** **disk** field description¶
Parameter	Mandatory	Type	Description
size	Yes	Integer	Specifies the disk size. The unit is GB. The system disk size ranges from 1 to 1024 and must be greater than or equal to the minimum size (min_disk value) of the system disk specified in the image. The data disk size ranges from 10 to 32768.
volume_type	Yes	String	Specifies the ECS system disk type. The disk type must match the available disk type. SATA: common I/O disk type SAS: high I/O disk type SSD: ultra-high I/O disk type co-p1: high I/O (performance-optimized I) disk type uh-l1: ultra-high I/O (latency-optimized) disk type If the specified disk type is not available in the AZ, the disk will fail to create. Note For HANA, HL1, and HL2 ECSs, use co-p1 and uh-l1 disks. For other ECSs, do not use co-p1 or uh-l1 disks.
disk_type	Yes	String	Specifies a disk type. The options are as follows: DATA: indicates a data disk. SYS: indicates a system disk. Note System disk encryption is not supported.
dedicated_storage_id	No	String	Specifies a DSS device ID for creating an ECS disk. Note Specify DSS devices for all disks in an AS configuration or not. If DSS devices are specified, all the data stores must belong to the same AZ, and the disk types supported by a DSS device for a disk must be the same as the volume_type value.
data_disk_image_id	No	String	Specifies the ID of a data disk image used to export data disks of an ECS.
snapshot_id	No	String	Specifies the disk backup snapshot ID for restoring the system disk and data disks using a full-ECS backup when a full-ECS image is used. Note Each disk in an AS configuration must correspond to a disk backup in the full-ECS backup by snapshot_id.
metadata	No	metadata object	Specifies the metadata for creating disks. For details, see Table 5.

**Table 5** **metadata** Field Description for Creating Disks¶
Parameter	Mandatory	Type	Description
__system__encrypted	No	String	Specifies encryption in metadata. The value can be 0 (encryption disabled) or 1 (encryption enabled). If this parameter does not exist, the disk will not be encrypted by default. Note System disk encryption is not supported.
__system__cmkid	No	String	Specifies the CMK ID, which indicates encryption in metadata. This parameter is used with __system__encrypted. Note For details about how to obtain the CMK ID, see "Querying the List of CMKs" in Key Management Service API Reference. System disk encryption is not supported.

**Table 6** **personality** field description¶
Parameter	Mandatory	Type	Description
path	Yes	String	Specifies the path of the injected file. For Linux OSs, specify the path, for example, /etc/foo.txt, for storing the injected file. For Windows, the injected file is automatically stored in the root directory of drive C. You only need to specify the file name, for example, foo. The file name contains only letters and digits.
content	Yes	String	Specifies the content of the injected file. The value must be the information after the content of the injected file is encoded using Base64.

**Table 7** **public_ip** field description¶
Parameter	Mandatory	Type	Description
eip	Yes	eip object	Specifies the EIP automatically assigned to the ECS. For details, see Table 8.

**Table 8** **eip** field description¶
Parameter	Mandatory	Type	Description
ip_type	Yes	String	Specifies the EIP type. Enumerated value of the IP address type: 5_bgp (indicates dynamic BGP)
bandwidth	Yes	bandwidth object	Specifies the bandwidth of an IP address. For details, see Table 9.

**Table 9** **bandwidth** field description¶
Parameter	Mandatory	Type	Description
size	Yes	Integer	Specifies the bandwidth (Mbit/s). The value ranges from 1 to 500. Note 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 unit for bandwidth varies depending on the bandwidth range. The minimum unit is 1 Mbit/s if the allowed bandwidth size ranges from 0 to 300 Mbit/s (with 300 Mbit/s included). The minimum unit is 50 Mbit/s if the allowed bandwidth size ranges 300 Mbit/s to 500 Mbit/s (with 500 Mbit/s included).
share_type	Yes	String	Specifies the bandwidth sharing type. Enumerated values of the sharing type: PER: dedicated Only dedicated bandwidth is available.
charging_mode	Yes	String	Specifies the bandwidth billing mode. traffic: billed by traffic. If the parameter value is out of the preceding options, creating the ECS will fail.
