Creating an ECS

Function

This API is used to create one or more ECSs.

The V1.1 API supports all functions (see Creating an ECS (Pay-per-Use)) provided by the V1 API. Additionally, the V1.1 API supports the creation of yearly/monthly ECSs.

This API is an asynchronous API. After the creation request is successfully delivered, a job ID is returned. This does not mean the creation is complete. You need to call the API by referring to Querying Task Execution Status to query the job status. The SUCCESS status indicates that the creation is successful.

This API allows you to set the X-Client-Token request header in the HTTP request header to ensure the request idempotence. For details, see Idempotent Requests.

Huawei Cloud no longer provides Windows images. This API cannot be used to create ECSs using Windows images, including public Windows images, private Windows images, shared Windows images, and Marketplace Windows images.

Logging in to an ECS can be authenticated using either a key pair or password. The login using a key pair is more secure than using a password, so the key pair authentication is recommended.
  • Key pair

    A key pair is used for ECS login authentication.

    Method of calling APIs: Use the key_name field to specify the key file used for logging in to the ECS. For details, see Table 2.

  • Password

    If you choose the initial password for authentication in an ECS, you can log in to the ECS using the username and its initial password. The initial password of user root is used for authentication in Linux, while that of user Administrator is used for authentication in Windows.

    Method of calling APIs: Use the adminPass field to specify the initial login password of the administrator account. For details about how to use the adminPass field, see Table 2. If an encrypted password is required for logging in to a Linux ECS that is created using an image with Cloud-Init installed, you can use the user_data field to inject the password. For details, see Table 2.

    If the user_data field is specified for a Linux ECS that is created using an image with Cloud-Init installed, the adminPass field becomes invalid.

  • Image password

    If you use a Linux private image to create an ECS, you can use the image password for login authentication.

    Method of calling APIs: If the image password is used, the key_name and adminPass fields do not need to be specified.

Constraints

  • When creating a yearly/monthly ECS, you can pay for it automatically or manually.
    • If isAutoPay in the request is set to true, automatic payments are used. The system automatically pays for order using the supported payment methods.
      • Discounts and cash coupons can be used in the following sequence:

        Discounts (only one at a time) > Cash coupons (only one at a time) > Account balance (first cash balance and then available credit) or monthly settlement

      • If the preceding payment methods cannot be used to accomplish the payment, the system automatically generates an unpaid order. You need to manually select a payment method on the console and pay for the order.

      For details, see Automatic Payments.

    • If isAutoPay in the request is set to false, manual payments are used. The system generates an unpaid order. You need to manually select a payment method on the console and pay for the order.
  • When you create a pay-per-use ECS, the system automatically uses available cash coupons.
  • If you want to unsubscribe from yearly/monthly resources, see Unsubscribing from Yearly/Monthly Resources.

A name must comply with the following rules:

  • The parameter value consists of 1 to 128 characters, including letters, digits, underscores (_), hyphens (-), and periods (.).
  • If more than one ECS is to be created (the count value is greater than 1), the system automatically adds a hyphen followed by a four-digit incremental number, such as -0000, to the end of each ECS name. If you specify a number, the name of the first new ECS will start from the specified number. In this case, the ECS name contains a maximum of 59 characters.
    NOTE:

    ECS hostnames comply with RFC 952 and RFC 1123 naming rules. It is recommended that you configure hostnames using digits, lowercase letters, and hyphens (-). Underscores (_) are converted into hyphens (-) by default.

  • If chargingMode in the extendparam parameter is set to prePaid, the ECS is billed in yearly/monthly payments, and a tenant can create a maximum of 100 ECSs. A maximum of 400 resources can be purchased at a time. For example, a purchased ECS includes mandatory resources, such as one cloud server and one system disk, and other optional resources, such as data disks, EIP, and bandwidth. All of these are included in 400 resources. The system will report an error when the number of resources exceeds 400.

  • The value of the tag can contain only uppercase letters, lowercase letters, digits, underscores (_), hyphens (-), and periods (.).
NOTE:
  • When you create ECSs, one ECS supports up to 10 tags.
  • The server_tags field provides the same functions as those of tags, but supports more keys and values, so the server_tags field is recommended.
