OpenStack Object Storage API Client Library

Workspace: tessl
Visibility: Public
Created: 3 months ago
Last updated: 3 months ago
Describes: pkg:pypi/python-swiftclient@4.8.x

To install, run

npx @tessl/cli install tessl/pypi-python-swiftclient@4.8.0

Python SwiftClient

A comprehensive Python client library for the OpenStack Swift Object Storage API, providing both a programmatic Python API and a command-line interface. It enables developers to interact with OpenStack Swift object storage services through a clean, well-documented interface that supports all core Swift operations including object upload/download, container management, metadata handling, and authentication.

Package Information

Package Name: python-swiftclient
Language: Python
Installation: pip install python-swiftclient
Python Requirements: >= 3.7

Core Imports

import swiftclient

For high-level operations:

from swiftclient import Connection

For bulk operations:

from swiftclient.service import SwiftService

For low-level HTTP operations:

from swiftclient import (
    get_auth, get_account, get_container, get_object,
    put_container, put_object, delete_object
)

Basic Usage

High-Level Connection API

from swiftclient import Connection

# Create connection with authentication
conn = Connection(
    authurl='https://identity.example.com:5000/v3',
    user='myuser',
    key='mypassword',
    auth_version='3',
    os_options={
        'project_name': 'myproject',
        'user_domain_name': 'mydomain',
        'project_domain_name': 'mydomain',
    }
)

# Account operations
headers, containers = conn.get_account()

# Container operations
conn.put_container('mycontainer')
headers, objects = conn.get_container('mycontainer')

# Object operations
conn.put_object('mycontainer', 'myobject', 'Hello World!')
headers, content = conn.get_object('mycontainer', 'myobject')
print(content.decode('utf-8'))  # 'Hello World!'

# Cleanup
conn.delete_object('mycontainer', 'myobject')
conn.delete_container('mycontainer')

Bulk Operations with SwiftService

from swiftclient.service import SwiftService, SwiftUploadObject

# Upload multiple objects
with SwiftService() as swift:
    # Upload local files
    upload_objects = [
        SwiftUploadObject('path/to/file1.txt', object_name='file1.txt'),
        SwiftUploadObject('path/to/file2.txt', object_name='file2.txt')
    ]

    for result in swift.upload('mycontainer', upload_objects):
        if result['success']:
            print(f"Uploaded {result['object']}")
        else:
            print(f"Failed to upload {result['object']}: {result['error']}")

Architecture

The python-swiftclient library provides multiple levels of abstraction for Swift operations:

Connection: High-level client with automatic retry, authentication handling, and connection management
Low-level Functions: Direct HTTP operations (get_object, put_object, etc.) for fine-grained control
SwiftService: Bulk operations with multi-threading, progress reporting, and automatic retries
Command Line: Full-featured CLI tool for all Swift operations

This multi-layered architecture allows developers to choose the appropriate abstraction level for their needs, from simple single operations to complex bulk processing workflows.

Capabilities

Command Line Interface

Complete command-line client for all Swift operations including upload, download, container management, and administrative tasks.

swift upload <container> <file>     # Upload objects
swift download <container>          # Download objects
swift list [<container>]           # List containers/objects
swift delete <container> [<object>] # Delete objects/containers
swift stat [<container>] [<object>] # Show statistics
swift post <container> [<object>]   # Update metadata
swift copy <container> <object>     # Copy objects
swift capabilities [<url>]          # Show cluster capabilities
swift auth                          # Show authentication info
swift tempurl <method> <seconds> <path> <key>  # Generate temporary URLs
swift bash_completion               # Enable shell completion

Command Line Interface

Client Connection

High-level Swift client providing automatic authentication, connection pooling, retry logic, and convenient wrapper methods for all Swift operations.

class Connection:
