Delete incomplete multipart uploads in S3 for cost optimization

• Created one folder s3-mp and set up the path to work on AWS cli
• Created one file called lifecycle-config.json to create a lifecycle rule

{

  “Rules”: [

    {

      “ID”: “AbortIncompleteMultipartUpload”,

      “Status”: “Enabled”,

      “Filter”: {},

      “AbortIncompleteMultipartUpload”: {

        “DaysAfterInitiation”: 7

      }

    }

  ]

}

• Called that file in each bucket using For loop script.

• For bucket in $(aws s3api list-buckets  –query  ‘Bucket[].Name’  –output text);

                 do

                     echo “Processing $bucket…”

                     aws s3api put-bucket-lifecycle-configuration\

                             –bucket  “$bucket”\

                             –lifecycle-configuration  file://lifecycle-config.json

                    done

• Change each environment keys and ran the script for all the accounts.
