Creating ECSs
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 is an asynchronous API. After the ECS creation request is issued, the system will return job_id. The ECS creation is still in progress. Therefore, you need to call the API described in Querying Task Execution Status to obtain the task status. When the status changes to SUCCESS, the ECS has been created.
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.
- 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.
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
- Ensure that your account has sufficient balance because this API does not support coupons. If the account balance is insufficient, a pending order will be generated.
