Subnet / Action / create_instances

create_instances#

EC2.Subnet.create_instances(**kwargs)#

Launches the specified number of instances using an AMI for which you have permissions.

You can specify a number of options, or leave the default options. The following rules apply:

  • If you don’t specify a subnet ID, we choose a default subnet from your default VPC for you. If you don’t have a default VPC, you must specify a subnet ID in the request.

  • All instances have a network interface with a primary private IPv4 address. If you don’t specify this address, we choose one from the IPv4 range of your subnet.

  • Not all instance types support IPv6 addresses. For more information, see Instance types.

  • If you don’t specify a security group ID, we use the default security group. For more information, see Security groups.

  • If any of the AMIs have a product code attached for which the user has not subscribed, the request fails.

You can create a launch template, which is a resource that contains the parameters to launch an instance. When you launch an instance using RunInstances, you can specify the launch template instead of specifying the launch parameters.

To ensure faster instance launches, break up large requests into smaller batches. For example, create five separate launch requests for 100 instances each instead of one launch request for 500 instances.

An instance is ready for you to use when it’s in the running state. You can check the state of your instance using DescribeInstances. You can tag instances and EBS volumes during launch, after launch, or both. For more information, see CreateTags and Tagging your Amazon EC2 resources.

Linux instances have access to the public key of the key pair at boot. You can use this key to provide secure access to the instance. Amazon EC2 public images use this feature to provide secure access without passwords. For more information, see Key pairs.

For troubleshooting, see What to do if an instance immediately terminates, and Troubleshooting connecting to your instance.

Parameters:

  • BlockDeviceMappings (list) –

    The block device mapping, which defines the EBS volumes and instance store volumes to attach to the instance at launch. For more information, see Block device mappings in the Amazon EC2 User Guide.

    • (dict) –

      Describes a block device mapping, which defines the EBS volumes and instance store volumes to attach to an instance at launch.

      • DeviceName (string) –

        The device name (for example, /dev/sdh or xvdh).

      • VirtualName (string) –

        The virtual device name ( ephemeral``N). Instance store volumes are numbered starting from 0. An instance type with 2 available instance store volumes can specify mappings for ``ephemeral0 and ephemeral1. The number of available instance store volumes depends on the instance type. After you connect to the instance, you must mount the volume.

        NVMe instance store volumes are automatically enumerated and assigned a device name. Including them in your block device mapping has no effect.

        Constraints: For M3 instances, you must specify instance store volumes in the block device mapping for the instance. When you launch an M3 instance, we ignore any instance store volumes specified in the block device mapping for the AMI.

      • Ebs (dict) –

        Parameters used to automatically set up EBS volumes when the instance is launched.

        • DeleteOnTermination (boolean) –

          Indicates whether the EBS volume is deleted on instance termination. For more information, see Preserving Amazon EBS volumes on instance termination in the Amazon EC2 User Guide.

        • Iops (integer) –

          The number of I/O operations per second (IOPS). For gp3, io1, and io2 volumes, this represents the number of IOPS that are provisioned for the volume. For gp2 volumes, this represents the baseline performance of the volume and the rate at which the volume accumulates I/O credits for bursting.

          The following are the supported values for each volume type:

          • gp3: 3,000-16,000 IOPS

          • io1: 100-64,000 IOPS

          • io2: 100-64,000 IOPS

          For io1 and io2 volumes, we guarantee 64,000 IOPS only for Instances built on the Nitro System. Other instance families guarantee performance up to 32,000 IOPS.

          This parameter is required for io1 and io2 volumes. The default for gp3 volumes is 3,000 IOPS. This parameter is not supported for gp2, st1, sc1, or standard volumes.

        • SnapshotId (string) –

          The ID of the snapshot.

        • VolumeSize (integer) –

          The size of the volume, in GiBs. You must specify either a snapshot ID or a volume size. If you specify a snapshot, the default is the snapshot size. You can specify a volume size that is equal to or larger than the snapshot size.

          The following are the supported volumes sizes for each volume type:

          • gp2 and gp3:1-16,384

          • io1 and io2: 4-16,384

          • st1 and sc1: 125-16,384

          • standard: 1-1,024

        • VolumeType (string) –

          The volume type. For more information, see Amazon EBS volume types in the Amazon EC2 User Guide. If the volume type is io1 or io2, you must specify the IOPS that the volume supports.

        • KmsKeyId (string) –

          Identifier (key ID, key alias, ID ARN, or alias ARN) for a customer managed CMK under which the EBS volume is encrypted.

          This parameter is only supported on BlockDeviceMapping objects called by RunInstances, RequestSpotFleet, and RequestSpotInstances.

        • Throughput (integer) –

          The throughput that the volume supports, in MiB/s.

          This parameter is valid only for gp3 volumes.

          Valid Range: Minimum value of 125. Maximum value of 1000.

        • OutpostArn (string) –

          The ARN of the Outpost on which the snapshot is stored.

          This parameter is not supported when using CreateImage.

        • Encrypted (boolean) –

          Indicates whether the encryption state of an EBS volume is changed while being restored from a backing snapshot. The effect of setting the encryption state to true depends on the volume origin (new or from a snapshot), starting encryption state, ownership, and whether encryption by default is enabled. For more information, see Amazon EBS encryption in the Amazon EC2 User Guide.

          In no case can you remove encryption from an encrypted volume.

          Encrypted volumes can only be attached to instances that support Amazon EBS encryption. For more information, see Supported instance types.

          This parameter is not returned by DescribeImageAttribute.

          For CreateImage and RegisterImage, whether you can include this parameter, and the allowed values differ depending on the type of block device mapping you are creating.

          • If you are creating a block device mapping for a new (empty) volume, you can include this parameter, and specify either true for an encrypted volume, or false for an unencrypted volume. If you omit this parameter, it defaults to false (unencrypted).

          • If you are creating a block device mapping from an existing encrypted or unencrypted snapshot, you must omit this parameter. If you include this parameter, the request will fail, regardless of the value that you specify.

          • If you are creating a block device mapping from an existing unencrypted volume, you can include this parameter, but you must specify false. If you specify true, the request will fail. In this case, we recommend that you omit the parameter.

          • If you are creating a block device mapping from an existing encrypted volume, you can include this parameter, and specify either true or false. However, if you specify false, the parameter is ignored and the block device mapping is always encrypted. In this case, we recommend that you omit the parameter.

      • NoDevice (string) –

        To omit the device from the block device mapping, specify an empty string. When this property is specified, the device is removed from the block device mapping regardless of the assigned value.

    • Network interfaces

    To tag a resource after it has been created, see CreateTags.

    • (dict) –

      The tags to apply to a resource when the resource is being created. When you specify a tag, you must specify the resource type to tag, otherwise the request will fail.

      Note

      The Valid Values lists all the resource types that can be tagged. However, the action you’re using might not support tagging all of these resource types. If you try to tag a resource type that is unsupported for the action you’re using, you’ll get an error.

  • CapacityReservationSpecification (dict) –

    Information about the Capacity Reservation targeting option. If you do not specify this parameter, the instance’s Capacity Reservation preference defaults to open, which enables it to run in any open Capacity Reservation that has matching attributes (instance type, platform, Availability Zone).

    • CapacityReservationPreference (string) –

      Indicates the instance’s Capacity Reservation preferences. Possible preferences include:

      • open - The instance can run in any open Capacity Reservation that has matching attributes (instance type, platform, Availability Zone).

  • MetadataOptions (dict) –

    The metadata options for the instance. For more information, see Instance metadata and user data.

    • HttpTokens (string) –

      IMDSv2 uses token-backed sessions. Set the use of HTTP tokens to optional (in other words, set the use of IMDSv2 to optional) or required (in other words, set the use of IMDSv2 to required).

      • optional - When IMDSv2 is optional, you can choose to retrieve instance metadata with or without a session token in your request. If you retrieve the IAM role credentials without a token, the IMDSv1 role credentials are returned. If you retrieve the IAM role credentials using a valid session token, the IMDSv2 role credentials are returned.

      • required - When IMDSv2 is required, you must send a session token with any instance metadata retrieval requests. In this state, retrieving the IAM role credentials always returns IMDSv2 credentials; IMDSv1 credentials are not available.

      Default: optional

    • HttpPutResponseHopLimit (integer) –

      The desired HTTP PUT response hop limit for instance metadata requests. The larger the number, the further instance metadata requests can travel.

      Default: 1

      Possible values: Integers from 1 to 64

  • EnclaveOptions (dict) –

    Indicates whether the instance is enabled for Amazon Web Services Nitro Enclaves. For more information, see What is Amazon Web Services Nitro Enclaves? in the Amazon Web Services Nitro Enclaves User Guide.

    You can’t enable Amazon Web Services Nitro Enclaves and hibernation on the same instance.

    • Enabled (boolean) –

      To enable the instance for Amazon Web Services Nitro Enclaves, set this parameter to true.

  • PrivateDnsNameOptions (dict) –

    The options for the instance hostname. The default values are inherited from the subnet. Applies only if creating a network interface, not attaching an existing one.

    • HostnameType (string) –

      The type of hostname for EC2 instances. For IPv4 only subnets, an instance DNS name must be based on the instance IPv4 address. For IPv6 only subnets, an instance DNS name must be based on the instance ID. For dual-stack subnets, you can specify whether DNS names use the instance IPv4 address or the instance ID.

    • EnableResourceNameDnsARecord (boolean) –

      Indicates whether to respond to DNS queries for instance hostnames with DNS A records.

    • EnableResourceNameDnsAAAARecord (boolean) –

      Indicates whether to respond to DNS queries for instance hostnames with DNS AAAA records.

  • MaintenanceOptions (dict) –

    The maintenance and recovery options for the instance.

    • AutoRecovery (string) –

      Disables the automatic recovery behavior of your instance or sets it to default. For more information, see Simplified automatic recovery.

  • DisableApiStop (boolean) – Indicates whether an instance is enabled for stop protection. For more information, see Stop protection.

  • EnablePrimaryIpv6 (boolean) – If you’re launching an instance into a dual-stack or IPv6-only subnet, you can enable assigning a primary IPv6 address. A primary IPv6 address is an IPv6 GUA address associated with an ENI that you have enabled to use a primary IPv6 address. Use this option if an instance relies on its IPv6 address not changing. When you launch the instance, Amazon Web Services will automatically assign an IPv6 address associated with the ENI attached to your instance to be the primary IPv6 address. Once you enable an IPv6 GUA address to be a primary IPv6, you cannot disable it. When you enable an IPv6 GUA address to be a primary IPv6, the first IPv6 GUA will be made the primary IPv6 address until the instance is terminated or the network interface is detached. If you have multiple IPv6 addresses associated with an ENI attached to your instance and you enable a primary IPv6 address, the first IPv6 GUA address associated with the ENI becomes the primary IPv6 address.
