How do I create a role with AWS managed policy using aws-cli?

Question

I am trying to create an IAM role with AWS managed policy, however it asks me for policy document.

aws iam create-role --role-name test-role 
usage: aws [options] <command> <subcommand> [<subcommand> ...] [parameters]
To see help text, you can run:

  aws help
  aws <command> help
  aws <command> <subcommand> help
aws: error: argument --assume-role-policy-document is required

I am trying to attach an aws managed policy like AWSLambdaFullAccess

信任策略定义了哪些主体实体（帐户、用户、角色和联合用户）可以承担该角色。每个 IAM 角色都需要信任策略。

通过 CLI 创建角色时，您必须指定信任策略。之后可以使用attach-role-policy或put-role-policy命令将基于身份的策略（托管/内联）附加到角色。

以下信任策略允许 Lambda 服务承担此角色。您必须提供此文件作为命令 usingassume-role-policy-document选项的输入。

信任策略.json

{
  "Version": "2012-10-17",
  "Statement": [
    {
      "Sid": "",
      "Effect": "Allow",
      "Principal": {
        "Service": "lambda.amazonaws.com"
      },
      "Action": "sts:AssumeRole"
    }
  ]
}

aws iam create-role --role-name Test-Role --assume-role-policy-document file://trust-policy.json

aws iam attach-role-policy --policy-arn arn:aws:iam::aws:policy/AWSLambdaFullAccess --role-name Test-Role
