How to copy s3 object from one bucket to another using python boto3

How to copy s3 object from one bucket to another using python boto3

You can use the boto3 library to copy an object from one S3 bucket to another. The copy_object() method in the boto3.client('s3') service allows you to accomplish this task. Here's how you can do it:

import boto3 # AWS credentials and configuration aws_access_key_id = 'YOUR_ACCESS_KEY_ID' aws_secret_access_key = 'YOUR_SECRET_ACCESS_KEY' region_name = 'YOUR_REGION_NAME' source_bucket = 'source-bucket' destination_bucket = 'destination-bucket' source_key = 'path/to/source/object.txt' # Specify the source object's key destination_key = 'path/to/destination/object.txt' # Specify the destination object's key # Initialize the S3 client s3 = boto3.client('s3', aws_access_key_id=aws_access_key_id, aws_secret_access_key=aws_secret_access_key, region_name=region_name) # Copy object from source bucket to destination bucket s3.copy_object(Bucket=destination_bucket, CopySource={'Bucket': source_bucket, 'Key': source_key}, Key=destination_key) print(f"Object copied from {source_bucket}/{source_key} to {destination_bucket}/{destination_key}")

Replace the placeholders (YOUR_ACCESS_KEY_ID, YOUR_SECRET_ACCESS_KEY, YOUR_REGION_NAME, source-bucket, destination-bucket, path/to/source/object.txt, path/to/destination/object.txt) with your actual AWS credentials, source and destination bucket information, and object keys.

The copy_object() method copies an object from the source bucket and key to the destination bucket and key. It also supports various additional parameters for controlling the copy behavior, such as metadata, ACLs, and storage class.

As always, ensure that your AWS credentials are kept secure and not hard-coded directly in your code. You can also consider using IAM roles for access to S3 resources.

Examples

  1. How to copy S3 object from one bucket to another using Python boto3?

    • Description: You can use the copy_object method of the boto3 S3 client to copy an object from one bucket to another.
    import boto3 # Initialize S3 client s3 = boto3.client('s3') # Copy object from source_bucket to target_bucket s3.copy_object(Bucket='target_bucket', CopySource={'Bucket': 'source_bucket', 'Key': 'source_key'}, Key='target_key')

  2. How to copy multiple S3 objects from one bucket to another using Python boto3?

    • Description: You can use a loop to copy multiple objects from one bucket to another using the copy_object method.
    import boto3 # Initialize S3 client s3 = boto3.client('s3') # List objects in source_bucket objects = s3.list_objects(Bucket='source_bucket')['Contents'] # Copy each object to target_bucket for obj in objects: copy_source = {'Bucket': 'source_bucket', 'Key': obj['Key']} s3.copy_object(Bucket='target_bucket', CopySource=copy_source, Key=obj['Key'])

  3. How to copy S3 object from one bucket to another with a different key using Python boto3?

    • Description: You can specify a different key in the target bucket while copying the object using the copy_object method.
    import boto3 # Initialize S3 client s3 = boto3.client('s3') # Copy object from source_bucket to target_bucket with different key s3.copy_object(Bucket='target_bucket', CopySource={'Bucket': 'source_bucket', 'Key': 'source_key'}, Key='target_key')

  4. How to copy S3 object from one bucket to another with metadata using Python boto3?

    • Description: You can include metadata while copying the object by specifying the MetadataDirective parameter in the copy_object method.
    import boto3 # Initialize S3 client s3 = boto3.client('s3') # Copy object from source_bucket to target_bucket with metadata s3.copy_object(Bucket='target_bucket', CopySource={'Bucket': 'source_bucket', 'Key': 'source_key'}, Key='target_key', MetadataDirective='COPY')

  5. How to copy S3 object from one bucket to another with server-side encryption using Python boto3?

    • Description: You can specify the ServerSideEncryption parameter in the copy_object method to enable server-side encryption for the copied object.
    import boto3 # Initialize S3 client s3 = boto3.client('s3') # Copy object from source_bucket to target_bucket with server-side encryption s3.copy_object(Bucket='target_bucket', CopySource={'Bucket': 'source_bucket', 'Key': 'source_key'}, Key='target_key', ServerSideEncryption='AES256')

  6. How to copy S3 object from one bucket to another using Python boto3 with versioning?

    • Description: If versioning is enabled on the source bucket, you can copy a specific version of the object using the copy_object method with the VersionId parameter.
    import boto3 # Initialize S3 client s3 = boto3.client('s3') # Copy specific version of object from source_bucket to target_bucket s3.copy_object(Bucket='target_bucket', CopySource={'Bucket': 'source_bucket', 'Key': 'source_key', 'VersionId': 'source_version_id'}, Key='target_key')

  7. How to copy S3 object from one bucket to another preserving ACL using Python boto3?

    • Description: You can preserve the ACL (Access Control List) while copying the object by specifying the ACL parameter in the copy_object method.
    import boto3 # Initialize S3 client s3 = boto3.client('s3') # Copy object from source_bucket to target_bucket preserving ACL s3.copy_object(Bucket='target_bucket', CopySource={'Bucket': 'source_bucket', 'Key': 'source_key'}, Key='target_key', ACL='bucket-owner-full-control')

  8. How to copy S3 object from one bucket to another asynchronously using Python boto3?

    • Description: You can copy the object asynchronously using the copy_object method with the AsyncRequest parameter set to True.
    import boto3 # Initialize S3 client s3 = boto3.client('s3') # Copy object asynchronously from source_bucket to target_bucket s3.copy_object(Bucket='target_bucket', CopySource={'Bucket': 'source_bucket', 'Key': 'source_key'}, Key='target_key', AsyncRequest='true')

  9. How to copy S3 object from one bucket to another with SSE-C encryption using Python boto3?

    • Description: You can specify the SSECustomerAlgorithm and SSECustomerKey parameters in the copy_object method to enable SSE-C (Server-Side Encryption with Customer-Provided Key) encryption for the copied object.
    import boto3 # Initialize S3 client s3 = boto3.client('s3') # Copy object from source_bucket to target_bucket with SSE-C encryption s3.copy_object(Bucket='target_bucket', CopySource={'Bucket': 'source_bucket', 'Key': 'source_key'}, Key='target_key', SSECustomerAlgorithm='AES256', SSECustomerKey='your_customer_key')

  10. How to copy S3 object from one bucket to another with tagging using Python boto3?

    • Description: You can specify the TaggingDirective and TagSet parameters in the copy_object method to add tags to the copied object.
    import boto3 # Initialize S3 client s3 = boto3.client('s3') # Copy object from source_bucket to target_bucket with tagging s3.copy_object(Bucket='target_bucket', CopySource={'Bucket': 'source_bucket', 'Key': 'source_key'}, Key='target_key', TaggingDirective='COPY', Tagging='key1=value1&key2=value2')
