create-launch-template

Description

Creates a launch template. A launch template contains the parameters to launch an instance. When you launch an instance using RunInstances , you can specify a launch template instead of providing the launch parameters in the request. For more information, see Launching an instance from a launch template in the Amazon Elastic Compute Cloud User Guide .

See also: AWS API Documentation

See 'aws help' for descriptions of global parameters.

--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.

See 'aws help' for descriptions of global parameters.

Examples

Example 1: To create a launch template

The following create-launch-template example creates a launch template that specifies the subnet in which to launch the instance , assigns a public IP address and an IPv6 address to the instance, and creates a tag for the instance.

aws ec2 create-launch-template \
    --launch-template-name TemplateForWebServer \
    --version-description WebVersion1 \
    --launch-template-data '{"NetworkInterfaces":[{"AssociatePublicIpAddress":true,"DeviceIndex":0,"Ipv6AddressCount":1,"SubnetId":"subnet-7b16de0c"}],"ImageId":"ami-8c1be5f6","InstanceType":"t2.small","TagSpecifications":[{"ResourceType":"instance","Tags":[{"Key":"purpose","Value":"webserver"}]}]}'

Output:

{
    "LaunchTemplate": {
        "LatestVersionNumber": 1,
        "LaunchTemplateId": "lt-01238c059e3466abc",
        "LaunchTemplateName": "TemplateForWebServer",
        "DefaultVersionNumber": 1,
        "CreatedBy": "arn:aws:iam::123456789012:user/Bob",
        "CreateTime": "2019-01-27T09:13:24.000Z"
    }
}

For more information, see Launching an Instance from a Launch Template in the Amazon Elastic Compute Cloud User Guide. For information about quoting JSON-formatted parameters, see Quoting Strings in the AWS Command Line Interface User Guide.

Example 2: To create a launch template for Amazon EC2 Auto Scaling

The following create-launch-template example creates a launch template with multiple tags and a block device mapping to specify an additional EBS volume when an instance launches. Specify a value for Groups that corresponds to security groups for the VPC that your Auto Scaling group will launch instances into. Specify the VPC and subnets as properties of the Auto Scaling group.

aws ec2 create-launch-template \
    --launch-template-name TemplateForAutoScaling \
    --version-description AutoScalingVersion1 \
    --launch-template-data '{"NetworkInterfaces":[{"DeviceIndex":0,"AssociatePublicIpAddress":true,"Groups":["sg-7c227019,sg-903004f8"],"DeleteOnTermination":true}],"ImageId":"ami-b42209de","InstanceType":"m4.large","TagSpecifications":[{"ResourceType":"instance","Tags":[{"Key":"environment","Value":"production"},{"Key":"purpose","Value":"webserver"}]},{"ResourceType":"volume","Tags":[{"Key":"environment","Value":"production"},{"Key":"cost-center","Value":"cc123"}]}],"BlockDeviceMappings":[{"DeviceName":"/dev/sda1","Ebs":{"VolumeSize":100}}]}' --region us-east-1

Output:

{
    "LaunchTemplate": {
        "LatestVersionNumber": 1,
        "LaunchTemplateId": "lt-0123c79c33a54e0abc",
        "LaunchTemplateName": "TemplateForAutoScaling",
        "DefaultVersionNumber": 1,
        "CreatedBy": "arn:aws:iam::123456789012:user/Bob",
        "CreateTime": "2019-04-30T18:16:06.000Z"
    }
}

For more information, see Creating a Launch Template for an Auto Scaling Group in the Amazon EC2 Auto Scaling User Guide. For information about quoting JSON-formatted parameters, see Quoting Strings in the AWS Command Line Interface User Guide.

Example 3: To create a launch template that specifies encryption of EBS volumes

The following create-launch-template example creates a launch template that includes encrypted EBS volumes created from an unencrypted snapshot. It also tags the volumes during creation. If encryption by default is disabled, you must specify the "Encrypted" option as shown in the following example. If you use the "KmsKeyId" option to specify a customer managed CMK, you also must specify the "Encrypted" option even if encryption by default is enabled.

aws ec2 create-launch-template \
  --launch-template-name TemplateForEncryption \
  --launch-template-data file://config.json
