For more information about the supported operating systems, see AWS OpsWorks Stacks Operating Systems .

The default option is the current Amazon Linux version. If you set this parameter to Custom , you must use the CreateInstance action's AmiId parameter to specify the custom AMI that you want to use. Block device mappings are not supported if the value is Custom . For more information about supported operating systems, see Operating Systems For more information about how to use custom AMIs with AWS OpsWorks Stacks, see Using Custom AMIs .

--ami-id (string)

A custom AMI ID to be used to create the instance. The AMI should be based on one of the supported operating systems. For more information, see Using Custom AMIs .

Note

If you specify a custom AMI, you must set Os to Custom .

--ssh-key-name (string)

The instance's Amazon EC2 key-pair name.

--availability-zone (string)

The instance Availability Zone. For more information, see Regions and Endpoints .

--virtualization-type (string)

The instance's virtualization type, paravirtual or hvm .

--subnet-id (string)

--block-device-mappings (list)

An array of BlockDeviceMapping objects that specify the instance's block devices. For more information, see Block Device Mapping . Note that block device mappings are not supported for custom AMIs.

(structure)

Describes a block device mapping. This data type maps directly to the Amazon EC2 BlockDeviceMapping data type.

DeviceName -> (string)

The device name that is exposed to the instance, such as /dev/sdh . For the root device, you can use the explicit device name or you can set this parameter to ROOT_DEVICE and AWS OpsWorks Stacks will provide the correct device name.

NoDevice -> (string)

Suppresses the specified device included in the AMI's block device mapping.

VirtualName -> (string)

The virtual device name. For more information, see BlockDeviceMapping .

Ebs -> (structure)

An EBSBlockDevice that defines how to configure an Amazon EBS volume when the instance is launched.

SnapshotId -> (string)

The snapshot ID.

Iops -> (integer)

The number of I/O operations per second (IOPS) that the volume supports. For more information, see EbsBlockDevice .

VolumeSize -> (integer)

The volume size, in GiB. For more information, see EbsBlockDevice .

VolumeType -> (string)

The volume type. gp2 for General Purpose (SSD) volumes, io1 for Provisioned IOPS (SSD) volumes, st1 for Throughput Optimized hard disk drives (HDD), sc1 for Cold HDD,and standard for Magnetic volumes.

If you specify the io1 volume type, you must also specify a value for the Iops attribute. The maximum ratio of provisioned IOPS to requested volume size (in GiB) is 50:1. AWS uses the default volume size (in GiB) specified in the AMI attributes to set IOPS to 50 x (volume size).

DeleteOnTermination -> (boolean)

Whether the volume is deleted on instance termination.

Shorthand Syntax:

DeviceName=string,NoDevice=string,VirtualName=string,Ebs={SnapshotId=string,Iops=integer,VolumeSize=integer,VolumeType=string,DeleteOnTermination=boolean} ...

JSON Syntax:

[
  {
    "DeviceName": "string",
    "NoDevice": "string",
    "VirtualName": "string",
    "Ebs": {
      "SnapshotId": "string",
      "Iops": integer,
      "VolumeSize": integer,
      "VolumeType": "gp2"|"io1"|"standard",
      "DeleteOnTermination": true|false
    }
  }
  ...
]

--install-updates-on-boot | --no-install-updates-on-boot (boolean)

Whether to install operating system and package updates when the instance boots. The default value is true . To control when updates are installed, set this value to false . You must then update your instances manually by using CreateDeployment to run the update_dependencies stack command or by manually running yum (Amazon Linux) or apt-get (Ubuntu) on the instances.

Note

We strongly recommend using the default value of true to ensure that your instances have the latest security updates.

--ebs-optimized | --no-ebs-optimized (boolean)

Whether to create an Amazon EBS-optimized instance.

--agent-version (string)

The default AWS OpsWorks Stacks agent version. You have the following options:

  • INHERIT - Use the stack's default agent version setting.
  • version_number - Use the specified agent version. This value overrides the stack's default setting. To update the agent version, edit the instance configuration and specify a new version. AWS OpsWorks Stacks then automatically installs that version on the instance.

The default setting is INHERIT . To specify an agent version, you must use the complete version number, not the abbreviated number shown on the console. For a list of available agent version numbers, call DescribeAgentVersions . AgentVersion cannot be set to Chef 12.2.

--tenancy (string)

The instance's tenancy option. The default option is no tenancy, or if the instance is running in a VPC, inherit tenancy settings from the VPC. The following are valid values for this parameter: dedicated , default , or host . Because there are costs associated with changes in tenancy options, we recommend that you research tenancy options before choosing them for your instances. For more information about dedicated hosts, see Dedicated Hosts Overview and Amazon EC2 Dedicated Hosts . For more information about dedicated instances, see Dedicated Instances and Amazon EC2 Dedicated Instances .

--cli-input-json (string) Performs service operation based on the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton. If other arguments are provided on the command line, the CLI values will override the JSON-provided values. It is not possible to pass arbitrary binary values using a JSON-provided value as the string will be taken literally.

--generate-cli-skeleton (string) Prints a JSON skeleton to standard output without sending an API request. If provided with no value or the value input, prints a sample input JSON that can be used as an argument for --cli-input-json. If provided with the value output, it validates the command inputs and returns a sample output JSON for that command.

Global Options

--debug (boolean)

Turn on debug logging.

--endpoint-url (string)

Override command's default URL with the given URL.

--no-verify-ssl (boolean)

The maximum socket read time in seconds. If the value is set to 0, the socket read will be blocking and not timeout. The default value is 60 seconds.

--cli-connect-timeout (int)

The maximum socket connect time in seconds. If the value is set to 0, the socket connect will be blocking and not timeout. The default value is 60 seconds.

Examples

Note

To use the following examples, you must have the AWS CLI installed and configured. See the Getting started guide in the AWS CLI User Guide for more information.

Unless otherwise stated, all examples have unix-like quotation rules. These examples will need to be adapted to your terminal's quoting rules. See Using quotation marks with strings in the AWS CLI User Guide .

To create an instance

The following create-instance command creates an m1.large Amazon Linux instance named myinstance1 in a specified stack. The instance is assigned to one layer.

aws opsworks --region us-east-1 create-instance --stack-id 935450cc-61e0-4b03-a3e0-160ac817d2bb --layer-ids 5c8c272a-f2d5-42e3-8245-5bf3927cb65b --hostname myinstance1 --instance-type m1.large --os "Amazon Linux"

To use an autogenerated name, call get-hostname-suggestion, which generates a hostname based on the theme that you specified when you created the stack. Then pass that name to the hostname argument.

Output:

{
  "InstanceId": "5f9adeaa-c94c-42c6-aeef-28a5376002cd"
}
