CloudWatch 이벤트 규칙의 대상을 추가하려면

다음 예시에서는 Lambda 함수를 규칙 대상으로 추가합니다.

aws events put-targets --rule DailyLambdaFunction --targets "Id"="1","Arn"="arn:aws:lambda:us-east-1:123456789012:function:MyFunctionName"

이 예시에서는 Amazon Kinesis 스트림을 대상으로 설정하여 이 규칙에 의해 포착된 이벤트가 스트림으로 전달되도록 합니다.

aws events put-targets --rule EC2InstanceStateChanges --targets "Id"="1","Arn"="arn:aws:kinesis:us-east-1:123456789012:stream/MyStream","RoleArn"="arn:aws:iam::123456789012:role/MyRoleForThisRule"

이 예시에서는 두 개의 Amazon Kinesis 스트림을 하나의 규칙 대상으로 설정합니다.

aws events put-targets --rule DailyLambdaFunction --targets "Id"="Target1","Arn"="arn:aws:kinesis:us-east-1:379642911888:stream/MyStream1","RoleArn"="arn:aws:iam::379642911888:role/ MyRoleToAccessLambda"  "Id"="Target2"," Arn"="arn:aws:kinesis:us-east-1:379642911888:stream/MyStream2","RoleArn"="arn:aws:iam::379642911888:role/MyRoleToAccessLambda"
