docker-chrome-session-manager 1.0.4

A Python module for managing Selenium Chrome sessions across multiple Docker containers.

Docker Chrome Session Manager

A Python module for managing Selenium Chrome sessions across multiple Docker containers. It provides dynamic container selection, session configuration persistence, and safe concurrent access for browser automation tasks.

Features

• Dynamic Container Management: Automatically selects available Selenium Chrome containers from a provided list.
• Session Configuration: Supports customizable browser settings such as user agent, locale, screen resolution, timezone, and additional Chrome options.
• Persistent Sessions: Stores session configurations in JSON files for reuse across sessions.
• Concurrent Access: Uses file locking to ensure safe access to session configurations.
• Logging: Comprehensive logging for debugging and monitoring session activities.
• Extensible: Easily integrates with Dockerized Selenium Chrome instances and supports custom configurations.

Installation

Prerequisites

• Python 3.9 or higher
• Docker and Docker Compose
• Poetry (optional, for dependency management)

Steps

Direct installation

Just use pip:

pip install docker-chrome-session-manager

Or Poetry:

poetry add docker-chrome-session-manager

Manual installation

1. Clone the repository:

   git clone https://github.com/FINWAX/docker-chrome-session-manager.py.git
   cd docker-chrome-session-manager
   

2. Install dependencies: Using Poetry (recommended):

   poetry install
   

   Alternatively, using pip:

   pip install -r requirements.txt
   

3. Set up Docker containers: Start the Selenium Chrome containers using the provided docker-compose.yml:

   docker-compose up -d
   

   This will start two Selenium Chrome containers on ports 4444 and 4445, with session data stored in the ./sessions directory.

Usage

The docker_chrome_session_manager module provides a SessionManager class to manage browser sessions. Below is an example of how to use it:

import logging
from docker_chrome_session_manager import SessionManager

# Configure logging
logging.basicConfig(
    level=logging.INFO,
    format='%(asctime)s - %(levelname)s - %(message)s',
    datefmt='%Y-%m-%d %H:%M:%S'
)

# Initialize SessionManager with container URLs
container_paths = ["http://localhost:4444", "http://localhost:4445"]
manager = SessionManager(container_paths=container_paths)

# Create a session configuration
resource_id = "test-session-123"
config = manager.provide_session_config(
    resource_id=resource_id,
    locale="en-US",
    timezone="America/New_York",
    extra_chrome_options=["--disable-notifications"]
)

# Start a browser session
driver = manager.get_remote_driver(resource_id, config)
if driver:
    try:
        driver.get("https://example.com")
        print(f"Page title: {driver.title}")
    finally:
        driver.quit()
        manager.forget_session_config(resource_id)  # Clean up session

See the example/example.py file for a more detailed example that demonstrates multiple sessions with different configurations.

Configuration

The SessionManagerConfig dataclass provides global settings for the SessionManager. Key parameters include:

• config_dir: Directory for storing session configuration files (default: config/sessions).
• session_dir: Directory for browser session data (default: /sessions in Docker containers).
• screen_resolutions: Available screen resolutions (e.g., (1920, 1080), (1280, 720)).
• default_locale: Default browser locale (e.g., en-US).
• user_agent_platforms: Platforms for generating user agents (e.g., desktop).
• file_lock_timeout: Timeout for file locking (default: 10 seconds).
• container_response_timeout: Timeout for container status checks (default: 3 seconds).

The SessionConfig dataclass allows customization of individual sessions, including:

• user_agent: Custom user agent string.
• locale: Browser locale (e.g., en-US, ru-RU).
• resolution: Screen resolution as a tuple (e.g., (1920, 1080)).
• timezone: Timezone ID (e.g., America/New_York).
• extra_chrome_options: Additional Chrome command-line options.

Running the Example

To run the example script provided in example/example.py:

1. Ensure Docker containers are running:

   docker-compose -f example/docker-compose.yml up -d
   

2. Run the example script:

   poetry run python example/example.py
   

   or, if using pip:

   python example/example.py
   

The script will create two browser sessions with different configurations, navigate to specified URLs, and log session details.
