AWS Cloudformation 为 ec2 用户数据调用 bash 脚本

如何解决AWS Cloudformation 为 ec2 用户数据调用 bash 脚本

我为 EC2 实例创建了一个 cloudformation 模板，它将在用户数据中设置 Tomcat。当脚本嵌入到模板中时，模板工作正常。但我想在单独的 bash 脚本（名为 tomcat.sh）中移动脚本，并使用 userdata 作为来自 AWS CLI 的 cfn 参数调用脚本。但得到错误

aws cloudformation create-stack --stack-name EC2Instance2 --template-url s3://cfn04012021/14-01-CFN-EC2-Instance2.yml --parameters ParameterKey=UserData,ParameterValue=$(base64 -w0 tomcat)

usage: aws [options] <command> <subcommand> [<subcommand> ...] [parameters]
To see help text,you can run:

  aws help
  aws <command> help
  aws <command> <subcommand> help

UnkNown options: -w0,tomcat)

cloudformation模板如下

AWstemplateFormatVersion: 2010-09-09

bash 脚本是
