ECS 日志保留设置

Question

我想通过

CDK

设置 ecs fargate 服务 logretantion

该服务有两个容器和一个LogGroup。

var logRetention = logs.RetentionDays.ONE_DAY 

const logGroup = new logs.LogGroup(this, 'ServiceLogGroup', {
  logGroupName: ecsInfos['logGroup'],
  removalPolicy: RemovalPolicy.DESTROY,

});
const nginxContainer = taskDefinitionAdmin.addContainer("NginxContainer", {
  image: nginxImage,
  containerName:ecsInfos['containerNginx'],
  logging: ecs.LogDriver.awsLogs({
    streamPrefix: "log-nginx",
    logRetention:logRetention,
    logGroup,
  }),
});

const djangoContainer = taskDefinitionAdmin.addContainer("DjangoContainer", {
  image: djangoImage,
  containerName:ecsInfos['containerDjango'],
  logging: ecs.LogDriver.awsLogs({
    streamPrefix: "log-django",
    logRetention:logRetention,
    logGroup,
  }),
});

此代码显示以下错误。

Error: Cannot specify both `logGroup` and `logRetentionDays`.

我想我应该在

logRetention

中设置

logs.LogGroup

，但是没有

logRetantion

属性。

我该如何解决这个问题？

Answer 1

如果您要创建

LogGroup

，那么您需要在 日志组 本身上设置保留：

const logGroup = new logs.LogGroup(this, 'ServiceLogGroup', {
  logGroupName: ecsInfos['logGroup'],
  removalPolicy: RemovalPolicy.DESTROY,
  retention: logRetention 
});

在任务定义中指定日志配置时，您可以指定现有日志组，也可以指定将为您创建的新日志组的所有其他设置。
