CLI

AWS CLI

Untuk membuat aturan CloudWatch Acara

Contoh ini membuat aturan yang dipicu setiap hari pada pukul 9:00 pagi (UTC). Jika Anda menggunakan put-target untuk menambahkan fungsi Lambda sebagai target aturan ini, Anda dapat menjalankan fungsi Lambda setiap hari pada waktu yang ditentukan:

aws events put-rule --name "DailyLambdaFunction" --schedule-expression "cron(0 9 * * ? *)"

Contoh ini membuat aturan yang memicu ketika setiap EC2 instance di wilayah mengubah status:

aws events put-rule --name "EC2InstanceStateChanges" --event-pattern "{\"source\":[\"aws.ec2\"],\"detail-type\":[\"EC2 Instance State-change Notification\"]}"  --role-arn "arn:aws:iam::123456789012:role/MyRoleForThisRule"

Contoh ini membuat aturan yang memicu ketika setiap EC2 instance di wilayah dihentikan atau dihentikan:

aws events put-rule --name "EC2InstanceStateChangeStopOrTerminate" --event-pattern "{\"source\":[\"aws.ec2\"],\"detail-type\":[\"EC2 Instance State-change Notification\"],\"detail\":{\"state\":[\"stopped\",\"terminated\"]}}" --role-arn "arn:aws:iam::123456789012:role/MyRoleForThisRule"
