|  | 5 | +## Development Environment Setup | 
|  | 6 | + | 
|  | 7 | +### Using Dev Containers (Recommended) | 
|  | 8 | + | 
|  | 9 | +This repository includes a complete development environment using Docker containers that provides everything you need to start contributing immediately. The devcontainer setup includes: | 
|  | 10 | + | 
|  | 11 | +- **Python 3.9** development environment with all necessary dependencies | 
|  | 12 | +- **YDB server** running locally in a container | 
|  | 13 | +- **Pre-configured tools**: Git, GitHub CLI, YDB CLI, and essential Python packages | 
|  | 14 | +- **VS Code extensions**: Python development tools, linting, formatting, and debugging support | 
|  | 15 | + | 
|  | 16 | +#### Prerequisites | 
|  | 17 | + | 
|  | 18 | +- [Docker](https://www.docker.com/get-started) installed and running | 
|  | 19 | +- [VS Code](https://code.visualstudio.com/) with the [Dev Containers extension](https://marketplace.visualstudio.com/items?itemName=ms-vscode-remote.remote-containers) | 
|  | 20 | + | 
|  | 21 | +#### Quick Start with Dev Containers | 
|  | 22 | + | 
|  | 23 | +1. Clone the repository: | 
|  | 24 | +   ```bash | 
|  | 25 | +   git clone https://github.com/ydb-platform/ydb-python-sdk.git | 
|  | 26 | +   cd ydb-python-sdk | 
|  | 27 | +   ``` | 
|  | 28 | + | 
|  | 29 | +2. Open in VS Code: | 
|  | 30 | +   ```bash | 
|  | 31 | +   code . | 
|  | 32 | +   ``` | 
|  | 33 | + | 
|  | 34 | +3. When prompted, click "Reopen in Container" or use the Command Palette (`Ctrl+Shift+P` / `Cmd+Shift+P`) and select "Dev Containers: Reopen in Container" | 
|  | 35 | + | 
|  | 36 | +4. Wait for the container to build and start (first time may take a few minutes) | 
|  | 37 | + | 
|  | 38 | +5. The development environment is ready! You can now run tests, debug code, and develop new features. | 
|  | 39 | + | 
|  | 40 | +### Using GitHub Codespaces | 
|  | 41 | + | 
|  | 42 | +GitHub Codespaces provides a cloud-based development environment that works directly in your browser or VS Code. It's perfect for quick contributions without setting up a local environment. | 
|  | 43 | + | 
|  | 44 | +#### Quick Start with Codespaces | 
|  | 45 | + | 
|  | 46 | +1. Navigate to the [repository on GitHub](https://github.com/ydb-platform/ydb-python-sdk) | 
|  | 47 | +2. Click the green "Code" button | 
|  | 48 | +3. Select the "Codespaces" tab | 
|  | 49 | +4. Click "Create codespace on main" (or your desired branch) | 
|  | 50 | +5. Wait for the environment to initialize (usually 2-3 minutes) | 
|  | 51 | +6. Start coding directly in the browser or connect with your local VS Code | 
|  | 52 | + | 
|  | 53 | +#### What's Included in the Development Environment | 
|  | 54 | + | 
|  | 55 | +When you use either dev containers or Codespaces, the following environment is automatically set up: | 
|  | 56 | + | 
|  | 57 | +**Container Services:** | 
|  | 58 | +- **SDK Container (`sdk`)**: Your main development environment running Python 3.9 on Debian Bookworm | 
|  | 59 | +- **YDB Container (`ydb`)**: Local YDB server (version 25.1) for testing and development | 
|  | 60 | + | 
|  | 61 | +**Development Tools:** | 
|  | 62 | +- **YDB CLI**: Pre-installed and configured to connect to the local YDB instance | 
|  | 63 | +- **Python Environment**: All project dependencies installed via `pip install -e .` | 
|  | 64 | +- **Git Configuration**: Automatic setup for signed commits (if configured) | 
|  | 65 | +- **VS Code Extensions**: Python development stack including linting, formatting, and debugging | 
|  | 66 | + | 
|  | 67 | +**Network Configuration:** | 
|  | 68 | +- **Port 2135**: YDB gRPC with TLS | 
|  | 69 | +- **Port 2136**: YDB gRPC without TLS | 
|  | 70 | +- **Port 8765**: YDB Monitoring interface | 
|  | 71 | +- These ports are automatically forwarded and accessible from your local machine | 
|  | 72 | + | 
|  | 73 | +**Environment Variables:** | 
|  | 74 | +The following environment variables are pre-configured for immediate use: | 
|  | 75 | +- `YDB_CONNECTION_STRING=grpc://ydb:2136/local` - Standard connection | 
|  | 76 | +- `YDB_CONNECTION_STRING_SECURE=grpcs://ydb:2135/local` - Secure connection | 
|  | 77 | +- `YDB_SSL_ROOT_CERTIFICATES_FILE=/ydb_certs/ca.pem` - SSL certificates | 
|  | 78 | +- `YDB_STATIC_CREDENTIALS_USER=root` and `YDB_STATIC_CREDENTIALS_PASSWORD=1234` - Test credentials | 
|  | 79 | + | 
|  | 80 | +**Automatic Setup Process:** | 
|  | 81 | +1. **Initialize**: Git configuration for signed commits and user settings | 
|  | 82 | +2. **Post-Create**: YDB CLI profile setup and GPG configuration for SSH signing | 
|  | 83 | +3. **Post-Start**: Installation of Python dependencies, SDK package, and testing tools (tox) | 
|  | 84 | + | 
|  | 85 | +#### Running Tests in the Development Environment | 
|  | 86 | + | 
|  | 87 | +Once your environment is ready, you can run the test suite: | 
|  | 88 | + | 
|  | 89 | +```bash | 
|  | 90 | +# Run all tests | 
|  | 91 | +tox | 
|  | 92 | + | 
|  | 93 | +# Run specific test categories | 
|  | 94 | +python -m pytest tests/ | 
|  | 95 | + | 
|  | 96 | +# Run with specific Python version | 
|  | 97 | +tox -e py39 | 
|  | 98 | +``` | 
|  | 99 | + | 
|  | 100 | +#### Connecting to the Local YDB Instance | 
|  | 101 | + | 
|  | 102 | +The YDB CLI is pre-configured to connect to the local instance: | 
|  | 103 | + | 
|  | 104 | +```bash | 
|  | 105 | +# Run a simple query | 
|  | 106 | +echo "SELECT 1;" | ydb | 
|  | 107 | + | 
|  | 108 | +# Access the web interface | 
|  | 109 | +# Open http://localhost:8765 in your browser (when using local dev containers) | 
|  | 110 | +# In codespaces you can access it via the provided URL in the terminal output. | 
|  | 111 | +``` | 
|  | 112 | + | 
|  | 113 | +## Manual Setup (Alternative) | 
|  | 114 | + | 
|  | 115 | +If you prefer to set up your development environment manually without using dev containers: |
