CloudWatch 日志组在 cdk destroy 时未删除

Question

我有这个 CDK 代码：

const logGroup = new LogGroup(this, 'MyAppLogGroup', {
  logGroupName: 'myapp',
  retention: RetentionDays.ONE_DAY
});

当我运行

cdk deploy

时，会在 CloudWatch 中创建日志组，但当我运行

cdk destroy

时，它不会被删除。有什么方法可以启用此功能吗？

Answer 1

请参阅 https://docs.aws.amazon.com/cdk/api/latest/docs/@aws-cdk_aws-logs.LogGroup.html#removalpolicy。您需要将

removalPolicy

的

LogGroup

设置为

DESTROY

，默认为

RETAIN

米兰在这里 100% 正确，我只是添加一些示例和更多关于如何做到这一点的细节..

import { RemovalPolicy } from "aws-cdk-lib";
import { LogGroup, RetentionDays } from "aws-cdk-lib/aws-logs";


const accessLogGroup = new LogGroup(this, 'MyAppLogGroup', {
    logGroupName: 'myapp',
    retention: RetentionDays.ONE_DAY,
    // This does the work:
    removalPolicy: RemovalPolicy.DESTROY
});
