Describes the specified instances or all instances.

If you specify instance IDs, the output includes information for only the specified instances. If you specify filters, the output includes information for only those instances that meet the filter criteria. If you do not specify instance IDs or filters, the output includes information for all instances, which can affect performance. We recommend that you use pagination to ensure that the operation returns quickly and successfully.

If you specify an instance ID that is not valid, an error is returned. If you specify an instance that you do not own, it is not included in the output.

Recently terminated instances might appear in the returned results. This interval is usually less than one hour.

If you describe instances in the rare case where an Availability Zone is experiencing a service disruption and you specify instance IDs that are in the affected zone, or do not specify any instance IDs at all, the call fails. If you describe instances and specify only instance IDs that are in an unaffected zone, the call works normally.

            • PrivateDnsName (string) --

              (IPv4 only) The private DNS hostname name assigned to the instance. This DNS hostname can only be used inside the Amazon EC2 network. This name is not available until the instance enters the running state.

              [EC2-VPC] The Amazon-provided DNS server resolves Amazon-provided private DNS hostnames if you've enabled DNS resolution and DNS hostnames in your VPC. If you are not using the Amazon-provided DNS server in your VPC, your custom domain name servers must resolve the hostname as appropriate.

            • PrivateIpAddress (string) --

              The private IPv4 address assigned to the instance.

            • ProductCodes (list) --

            • PublicIpAddress (string) --

              The public IPv4 address, or the Carrier IP address assigned to the instance, if applicable.

              A Carrier IP address only applies to an instance launched in a subnet associated with a Wavelength Zone.

            • RamdiskId (string) --

              The RAM disk associated with this instance, if applicable.

            • State (dict) --

              The current state of the instance.

              • Code (integer) --

                The state of the instance as a 16-bit unsigned integer.

                The high byte is all of the bits between 2^8 and (2^16)-1, which equals decimal values between 256 and 65,535. These numerical values are used for internal purposes and should be ignored.

                The low byte is all of the bits between 2^0 and (2^8)-1, which equals decimal values between 0 and 255.

                The valid values for instance-state-code will all be in the range of the low byte and they are:

                • 0 : pending

                • 16 : running

                • 32 : shutting-down

                • 48 : terminated

                • 64 : stopping

                • 80 : stopped

                You can ignore the high byte value by zeroing out all of the bits above 2^8 or 256 in decimal.

              • Name (string) --

                The current state of the instance.

ModifyInstanceMetadataOptions (updated) Link ¶
Changes (request, response)
Request
{'HttpProtocolIpv6': 'disabled | enabled'}
Response
{'InstanceMetadataOptions': {'HttpProtocolIpv6': 'disabled | enabled'}}

Modify the instance metadata parameters on a running or stopped instance. When you modify the parameters on a stopped instance, they are applied when the instance is started. When you modify the parameters on a running instance, the API responds with a state of “pending”. After the parameter modifications are successfully applied to the instance, the state of the modifications changes from “pending” to “applied” in subsequent describe-instances API calls. For more information, see Instance metadata and user data in the Amazon EC2 User Guide .

        pending - The metadata options are being updated and the instance is not ready to process metadata traffic with the new selection.

        applied - The metadata options have been successfully applied on the instance.

      • HttpTokens (string) --

        The state of token usage for your instance metadata requests. If the parameter is not specified in the request, the default state is optional .

        If the state is optional , you can choose to retrieve instance metadata with or without a signed token header on your request. If you retrieve the IAM role credentials without a token, the version 1.0 role credentials are returned. If you retrieve the IAM role credentials using a valid signed token, the version 2.0 role credentials are returned.

        If the state is required , you must send a signed token header with any instance metadata retrieval requests. In this state, retrieving the IAM role credential always returns the version 2.0 credentials; the version 1.0 credentials are not available.

      • 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

      • HttpEndpoint (string) --

        This parameter enables or disables the HTTP metadata endpoint on your instances. If the parameter is not specified, the default state is enabled .

        Note

        If you specify a value of disabled , you will not be able to access your instance metadata.

      • HttpProtocolIpv6 (string) --

        Whether or not the IPv6 endpoint for the instance metadata service is enabled or disabled.

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:

  • [EC2-VPC] 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.

  • [EC2-Classic] If don't specify an Availability Zone, we choose one for you.

  • Some instance types must be launched into a VPC. If you do not have a default VPC, or if you do not specify a subnet ID, the request fails. For more information, see Instance types available only in a VPC .

  • [EC2-VPC] 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 .

type BlockDeviceMappings

list

param BlockDeviceMappings

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
