public class LaunchTemplate
extends Resource
implements ILaunchTemplate, IGrantable, IConnectable

This represents an EC2 LaunchTemplate.

Example:

 UserData bootHookConf = UserData.forLinux();
 bootHookConf.addCommands("cloud-init-per once docker_options echo 'OPTIONS=\"${OPTIONS} --storage-opt dm.basesize=40G\"' >> /etc/sysconfig/docker");
 UserData setupCommands = UserData.forLinux();
 setupCommands.addCommands("sudo yum install awscli && echo Packages installed らと > /var/tmp/setup");
 MultipartUserData multipartUserData = new MultipartUserData();
 // The docker has to be configured at early stage, so content type is overridden to boothook
 multipartUserData.addPart(MultipartBody.fromUserData(bootHookConf, "text/cloud-boothook; charset=\"us-ascii\""));
 // Execute the rest of setup
 multipartUserData.addPart(MultipartBody.fromUserData(setupCommands));
 LaunchTemplate.Builder.create(this, "")
         .userData(multipartUserData)
         .blockDevices(List.of())
         .build();
