Anda harus memastikan bahwa IAM peran yang Anda gunakan untuk kebijakan tersebut memberikan izin kepada Amazon Data Lifecycle Manager untuk melakukan SSM tindakan yang diperlukan untuk menjalankan skrip pra dan pasca pada instans yang ditargetkan oleh kebijakan.

Amazon Data Lifecycle Manager menyediakan kebijakan terkelola (AWSDataLifecycleManagerSSMFullAccess) yang menyertakan izin yang diperlukan. Anda dapat melampirkan kebijakan ini ke IAM peran Anda untuk mengelola snapshot guna memastikan bahwa kebijakan tersebut menyertakan izin.

Atau, Anda dapat membuat kebijakan khusus secara manual atau menetapkan izin yang diperlukan langsung ke IAM peran yang Anda gunakan. Anda dapat menggunakan izin yang sama yang ditentukan dalam kebijakan AWSDataLifecycleManagerSSMFullAccess terkelola, namun, kunci aws:ResourceTag kondisi bersifat opsional. Jika Anda memutuskan untuk tidak menggunakan kunci kondisi itu, maka Anda tidak perlu menandai SSM dokumen AndaDLMScriptsAccess:true.

Gunakan salah satu metode berikut untuk menambahkan AWSDataLifecycleManagerSSMFullAccesskebijakan ke IAM peran Anda.
