Operation description

Usage notes

  • Preparations:

    • Cost estimation: Learn about the billing methods of ECS resources. For more information, see Billing overview.
    • Instance type selection: Call the DescribeInstanceTypes operation to query the performance data of instance types, or see Best practices for instance type selection to learn about how to select instance types.
    • Query of available resources: Call the DescribeAvailableResource operation to query resources available in a specific region or zone.
    • Network planning: Make sure that you have security groups available for use. For more information, see CreateSecurityGroup . Before you create an instance of the Virtual Private Cloud (VPC) type, create a VPC in the region where you want to create the instance. For more information, see Create a VPC.
  • Comparison with CreateInstance:

    RunInstances has the following advantages over CreateInstance:

    • You can call the RunInstances operation to create up to 100 instances at a time, instead of repeatedly calling the CreateInstance operation.
    • After an instance is created, the instance enters the Starting state and then transitions to the Running state. You do not need to call the StartInstance operation to start the instance.
    • When you create an instance, you can specify InternetMaxBandwidthOut to assign a public IP address to the instance, without the need to call the AllocatePublicIpAddress operation.
    • You can use AutoReleaseTime to set the time when to automatically release the instances, without the need to call the ModifyInstanceAutoReleaseTime operation.
    • You can specify LaunchTemplateId and LaunchTemplateVersion to use a launch template. This way, you do not need to configure a large number of parameters every time you create instances.
    • You can specify UniqueSuffix to batch configure sequential names or hostnames for multiple instances for easy management and retrieval.
    • When you call the RunInstances operation to create instances, you can configure the enclave-based confidential computing mode and the trusted system mode for the instances.
    • You can set NetworkOptions.EnableJumboFrame to true to enable the Jumbo Frames feature when you create instances. For more information, see MTUs .
  • Considerations:

    • You can create up to 100 instances at a time.

    • You can use AutoReleaseTime to set the time when to automatically release the instances.

    • After you create instances and obtain their IDs, you can call the DescribeInstances operation to check the status of the instances.

    • By default, instances automatically start after they are created. Instances are ready for use when they are in the Running (Running) state.

    • Starting November 27, 2020, the maximum bandwidth value that is available for you to create ECS instances or change ECS instance configurations is subject to the throttling policy of your account. To increase the maximum bandwidth value, submit a ticket. The throttling policy imposes the following constraints: In a single region, the total maximum bandwidth value of all instances that use the pay-by-traffic billing method for network usage cannot exceed 5 Gbit/s and the total maximum bandwidth value of all instances that use the pay-by-bandwidth billing method for network usage cannot exceed 50 Gbit/s.

    • Different from the CreateInstance operation, the RunInstances operation allows the system to assign public IP addresses to new instances if you set InternetMaxBandwidthOut to a value greater than 0.

    • When you call the RunInstances operation to create an instance, you can use one of the following methods to attach a primary elastic network interface (ENI) to the instance. Take note that you can use only one of the methods to configure the primary ENI in each call. Otherwise, the call fails and an error message is returned. - Specify parameters such as SecurityGroupId, VSwitchId, PrivateIpAddress, NetworkInterfaceQueueNumber, and Ipv6AddressCount to configure the primary ENI. - Specify parameters that start with NetworkInterface.N. to configure the primary and secondary ENIs. If NetworkInterface.N.InstanceType is set to Primary, the primary ENI is attached to the instance. If NetworkInterface.N.InstanceType is set to Secondary or left empty, a secondary ENI is attached to the instance.

    • If a parameter is invalid or available resources are insufficient, an error is returned after you call the RunInstances operation. For more information, see the "Error codes" section of this topic.

       - If the maximum number of instances of the specified instance type that can be created in the specified region or the maximum number of vCPUs for all instance types in a zone is exceeded, the QuotaExceed.ElasticQuota error is returned when you call the operation. You can go to the ECS console (https://ecs.console.aliyun.com/?spm=a2c8b.12215451.favorites.decs.5e3a336aMGTtzy#/privileges/quota) or Quota Center (https://quotas.console.aliyun.com/products/ecs/quotas) to request a quota increase. If the capacity of disks that belong to the specified disk category exceeds the quota limit for the specified zone, the QuotaExceed.DiskCapacity error is returned when you call the operation. You can go to the Quota Center (https://quotas.console.aliyun.com/products/disk/quotas) to view and increase the disk capacity quota.
      
  • Best practices:

    • We recommend that you use auto provisioning groups in the following scenarios: Resources are insufficient to create more than 100 instances at a time, you want to quickly create instances regardless of resource configurations such as instance types or zones, or you want to create instances to consume a specific total number of vCPUs regardless of the number of instances. You can call the CreateAutoProvisioningGroup operation to create an auto provisioning group to deploy an instance cluster across different zones and by using different billing methods and instance families. For more information, see Use auto provisioning group-related API operations to create multiple ECS instances at the same time.
    • You can call the RunInstances operation to batch create instances. To better manage and search for the instances, we recommend that you add tags to the instances by specifying Tag.N.Key and Tag.N.Value. You can also append incremental suffixes (UniqueSuffix) to the hostname (HostName) and to the instance name (InstanceName).
    • A launch template contains parameters required to create an instance so that you do not have to specify these parameters every time you create instances. You can call the CreateLaunchTemplate operation to create a launch template. Then, in your request to call the RunInstances operation, you can specify LaunchTemplateId and LaunchTemplateVersion to use the launch template.
