Creating an AS Configuration from an Existing ECS Instance

Scenarios

You can use an existing ECS instance to rapidly create an AS configuration. In such a case, the parameter settings, such as the ECS type, vCPUs, memory, image, and disk settings (including size and type) in the AS configuration are the same as those of the selected instance by default.

Procedure

1. Log in to the management console.
2. Under Computing, click Auto Scaling.
3. Click Create AS Configuration.
4. Set the parameters for the AS configuration. Table 1 lists the AS configuration parameters.

   Table 1 AS configuration parameters

   Parameter	Description	Example Value
   Name	Specifies the name of an AS configuration.	N/A
   Configuration Template	Choose Use specifications of an existing ECS > Select ECS. In such a case, the parameter settings, such as the ECS type, vCPUs, memory, image, and disk settings (including size, type, encryption, and key) in the AS configuration are the same as those of the selected instance by default.	Use specifications of an existing ECS
   EIP	An EIP is a static public IP address bound to an ECS in a VPC. Using the EIP, the ECS provides services externally. The following options are provided: Do not use An ECS without an EIP cannot access the Internet. However, it can still be used as a service ECS or deployed in a cluster on a private network. Automatically assign An EIP with a dedicated bandwidth is automatically assigned to each ECS. The bandwidth size is configurable.	Automatically assign
   Login Mode	An ECS can be authorized using a key pair or a password. Key pair Keys are used for authenticating the users who attempt to log in to ECS instances. If you select this mode, create or import a key pair on the Key Pair page. NOTE: If you use an existing key, make sure that you have saved the key file locally. Without the key, you will not be able to log in to your instance. Password The initial password of user root (for Linux) or user Administrator (for Windows) is used for authentication. You can log in to an ECS instance using a username and password combination.	Admin@123
   User Data	Enables the ECS instance to automatically inject user data when the instance starts for the first time. This configuration is optional.	N/A

5. Click Create Now. The Confirm Specifications page is displayed.
6. Check the AS configuration and click Confirm Application.

   The system displays a message indicating that the AS configuration has been created and switches to the AS Configurations page. You can view the newly created AS configuration on the AS Configurations page.

7. If you want to use the newly created AS configuration, add it to the AS group. For details, see Changing the AS Configuration for an AS Group.
