Dynamic value for create_multipart_upload

1. Create a Configuration for Each Bucket: Define the required parameters for each bucket in a dictionary.
2. Construct the Parameters Dynamically: Use Python's dictionary to pass the parameters to the create_multipart_upload function.
3. Call the create_multipart_upload Function: Pass the dynamically constructed dictionary as arguments to the function.

Here’s a complete example:

Step 1: Define the Configuration

Create a configuration dictionary that contains the required parameters for each bucket.

buckets_config = {
    'bucket1': {
        'Bucket': 'bucket1-name',
        'Key': 'object-key',
        'ServerSideEncryption': 'aws:kms',
        'SSEKMSKeyId': 'kms-key-id'
    },
    'bucket2': {
        'Bucket': 'bucket2-name',
        'Key': 'object-key',
        'ACL': 'public-read'
    },
    'bucket3': {
        'Bucket': 'bucket3-name',
        'Key': 'object-key',
        'ACL': 'private',
        'ServerSideEncryption': 'aws:kms',
        'SSEKMSKeyId': 'kms-key-id'
    },
    'bucket4': {
        'Bucket': 'bucket4-name',
        'Key': 'object-key'
    }
}

Step 2: Construct the Parameters Dynamically

Use a function to construct and call the create_multipart_upload function dynamically based on the provided configuration.

import boto3

s3_client = boto3.client('s3')

def create_multipart_upload_dynamic(bucket_config):
    response = s3_client.create_multipart_upload(**bucket_config)
    return response

# Example usage
for bucket_name, config in buckets_config.items():
    print(f"Starting multipart upload for {bucket_name}")
    response = create_multipart_upload_dynamic(config)
    print(response)

Explanation

1. Configuration Dictionary:

The buckets_config dictionary holds the configuration for each bucket. The keys are the bucket identifiers, and the values are dictionaries containing the parameters required for the create_multipart_upload function.

2. Dynamic Parameter Construction:

The create_multipart_upload_dynamic function accepts the bucket configuration as an argument and unpacks it using **bucket_config. This dynamically passes the parameters to the create_multipart_upload function.

3. Iterating and Calling the Function:

The example usage iterates over the buckets_config dictionary and calls the create_multipart_upload_dynamic function for each bucket configuration.

4. Handling Errors

You might want to add error handling to deal with any issues that arise during the upload process.

def create_multipart_upload_dynamic(bucket_config):
    try:
        response = s3_client.create_multipart_upload(**bucket_config)
        return response
    except Exception as e:
        print(f"Error during multipart upload for {bucket_config['Bucket']}: {e}")
        return None
