我想通过 Lambda 函数 SSH 到 EC2 实例，我已经为 paramiko 库创建了一个层。 lambda 函数获取了库，但它给了我这个错误：
Response

"errorType": "Runtime.ExitError",
"errorMessage": "RequestId: 26d4c295-51f8-4d98-b698-277a3e43336d Error: Runtime exited with error: exit status 1"
}

我已将内存大小增加到 512 MB，并使用 Amazon Linux 2 创建了 paramiko 层，因此它不会有任何依赖项问题
通过 Lambda 连接到 EC2
我建议的另一个选择是使用 AWS SSM 从 lambda 函数触发 EC2 中的操作。
