| **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",

|
| **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

|
| **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
|
|
|
