我正在使用cloudformation启动ec2实例。我使用的是我在网上找到的模板

然后我运行命令
aws cloudformation create-stack --stack-name newteststack777 --template-body file://launch-instance.json --parameters ParameterKey=KeyName,ParameterValue=StagingKey ParameterKey=InstanceType,ParameterValue=t3.medium
这将创建一个实例，但使用亚马逊的ami，但我想使用ubuntu启动一个实例。我应该在模板中的什么位置以及在什么位置上获得理想的结果。我是cloudformation的新手，所以这对我来说有点困惑
任何帮助将不胜感激。
