Steps related to ECS instances

Step	Description	Input parameter	Output parameter
Create an instance with the same configuration as an existing instance	You can use this step to create an instance with the same configuration as an existing instance. tip You cannot use this step to associate an EIP with an instance. For information about how to associate an EIP with a new instance, see Associating EIP.	Instance ID: The instance serving as a template to create an instance. Agent: Select whether to install the Cloud assistant Agent when creating the instance. Number of instances: The number of new instances that you want to purchase. Purchase duration: When you create a subscription instance, you need to specify this parameter. tip When the source instance uses password-based login, you need to specify the login password for the new instance: Login password: Enter the login password for the new instance. Confirm password: Re-enter the login password. If the source instance uses key pair-based login, the new instance automatically uses the key pair of the source instance for login.	Instance ID: The IDs of new instances, arranged in a list.
Create an instance	You can use this step to create an ECS instance. tip A successfully created instance is in the Running status and does not need to be started manually.	Billing method: Select a billing method for the instance. Availability zone: Select the availability zone where the new instance is created. Computing specification: Select the computing specification that meets your business requirements. Image: Select the required image. VPC: Select an existing VPC based on your business requirements. You can also manually create a new VPC. For more information, see Creating VPCs. Subnet: Select a subnet to assign a primary private IP address to the primary network interface of the instance. You can manage the instance network by using the network interface. Secondary network interface: Select a subnet to assign a secondary network interface to the instance. After the instance is created, enable the secondary network interface and configure the network interface route. For more information, see Configuring network routes. Security group: Select the security group where the instance resides. Login credentials: Select the security credentials for logging in to the ECS instance. Instance name: Specify the name of the ECS instance. By default, the system automatically generates instance names based on the product name. You can also change the name based on your needs. Custom data: Configure custom data for the instance. You can use instance custom data to make the system automatically configure the instance or pass in data when the instance starts up. Number of instances: The number of instances that you want to purchase. warning To reduce parameter configuration time, the system automatically assigns some parameters. You can modify these parameters based on your business requirements after the instance is created. The following items describe the parameters automatically assigned by the system and the parameters that are not automatically configured. Region: The region of the new instance is the region displayed before you go to the "Create orchestration task" or "Create orchestration plan" page. EBS Volume: By default, the instance is allocated a 40 GiB ESSD as the system volume. No data volumes are allocated. Project: The default project is automatically used. Parameters such as the EIP, Tag, and Deployment set parameters are not configured.	Instance ID: The IDs of new instances, arranged in a list.
Delete multiple ECS instances at one time	You can use this step to delete multiple ECS instances at one time.	Instance ID: The ID of the instance that you want to delete. warning You can delete only pay-as-you-go instances. If you select "Custom input", you can select multiple instances.	-
Stop multiple instances at one time	You can use this step to stop multiple ECS instances at one time.	Instance ID: The ID of the instance that you want to stop. How to stop: The method used to stop the instance. The following options are supported: Stop: the default and regular method that follows the standard procedure for stopping ECS instances. Forced stop: The running ECS instances are forced to stop, which is equivalent to a power-off operation. Bare metal instances currently only support forced stop. Performing a forced stop will cause all cached data not stored to storage devices to be lost. We recommend that you do not perform this operation on instances running normally. Stop mode: The stop mode. The following options are supported. Normal Mode: After the instance is stopped, the instance is retained and you are charged for the instance. Economical Mode: If you have enabled the allowlist policy and the selected instances include pay-as-you-go instances without mounted local volumes, you can select Economical Mode. For more information, see Economical Mode description. Subscription instances, bare metal instances, and HPC-optimized instances do not currently support Economical Mode.	Stop result: Whether each instance is stopped, arranged in a list.
Start multiple instances at one time	You can use this step to start multiple ECS instances at one time.	Instance ID: Specify the ID of the instance that you want to start.	Start results: Whether each instance is started, arranged in a list.
Change the operating system for multiple instances at one time	You can use this step to change the operating system of multiple existing instances at one time.	Instance ID: The ID of the instance for which you want to change the operating system. Image: The new image. You can select "Public Image", "Custom Image", or "Shared Image". Login credentials: The credentials for logging in to the new system. You can select "Password", "Key pair" or "Keep image logged in". tip Before you change the operating system, stop the target instance.	Instance status: The status of each instance, arranged in a list.
Restart multiple instances at one time	You can use this step to restart multiple ECS instances at one time.	Instance ID: Specify the ID of the instance that you want to restart. How to restart: Specify the restart method for the instance. The following options are supported: Restart: the default and standard restart mode. Forced restart: Forcibly power off the running instance and then restart it. For instances other than bare metal instances, performing a forced restart will result in the loss of all cached data not stored to storage devices to be lost. Therefore, we recommend against performing this operation on instances running normally. tip Bare metal instances currently can only be restarted in forced restart mode.	Start result: Whether each instance is restarted, arranged in a list.
Change the billing method to subscription for multiple instances at one time	You can use this step to change the billing method of multiple instances from pay-as-you-go to subscription at one time. tip For information on the conditions and restrictions, see Changing from pay-as-you-go to subscription.	Instance ID: The ID of the instance for which you want to change the billing method. Purchase duration: Select a subscription duration. Automatic renewal: Select whether to enable automatic renewal. This option is not selected by default. Storage Volume: Select whether to convert the pay-as-you-go data volumes mounted on the instance to subscription data volumes. This option is not selected by default.	Instance ID: The IDs of instances for which you want to change the billing method, arranged in a list. Billing method: The current billing methods of instances, arranged in a list. Order ID: The order IDs corresponding to this change, arranged in a list.
Change the types of multiple instances at one time	You can use this step to upgrade or downgrade the configuration of multiple instances at one time. tip Before you change the type of an instance, stop the instance first. When you change the type of an instance, the instance starts immediately. Confirm the impact on your business and proceed with caution. Before the instance type change is completed, do not perform any other operations on the instance. Otherwise, the instance type change may fail. For more information on conditions and restrictions, see Changing instance types.	Instance ID: Specify the ID of the instance whose type you want to change. Billing method: Confirm the billing method of the selected instance. After the step is executed, you cannot change the billing method.
