如何从fargate任务设置/写入aws日志组

Question

我已经通过cloudformation模板设置了一个fargate任务(见下面的示例(，该任务的代码在下面的script.py文件中。我成功地设置了任务，现在我想向cloudwatch写入日志。在设置fargate任务的同时，我已经建立了一个日志组，并计划使用python中的logger来编写日志。如何使用python中的logger从script.py向我用fargate任务创建的aws日志组写入。

您只需要将Python记录器配置为输出到STDOUT/STDERR(我认为这是默认情况下它所做的(。ECS中docker容器主进程的控制台输出是发送到CloudWatch日志的内容。
