Delete All S3 Object Versions

README.md

Delete All S3 Object Versions

Use this script to delete all object versions in a S3 bucket. For very large object version counts it may be more effective to use Object Lifecycle Management instead to expire versions.

Usage

python delete-object-versions.py (s3-bucket-name)

delete-object-versions.py

#!/usr/bin/env python

import sys

import boto3

BUCKET = sys.argv[1]

print(f'Deleting all object for bucket:"{BUCKET}"')

client = boto3.client('s3')

paginator = client.get_paginator('list_object_versions')

for page in paginator.paginate(Bucket=BUCKET):
    versions = []

    for version_type in ('DeleteMarkers', 'Versions'):
        try:
            for version in page[version_type]:
                version_tuple = (version['Key'], version['VersionId'])
                versions.append(version_tuple)

        except KeyError:
            # Ignore missing version type keys as there is nothing to do
            pass

    for key, version_id in versions:
        print(f'Deleting key:"{key}" version_id:"{version_id}"')
        client.delete_object(
            Bucket=BUCKET,
            Key=key,
            VersionId=version_id,
        )
