The CLI uses a langgraph.json configuration file with these key settings:

{
  "dependencies": ["langchain_openai", "./your_package"],  // Required: Package dependencies
  "graphs": {
    "my_graph": "./your_package/file.py:graph"            // Required: Graph definitions
  },
  "env": "./.env",                                        // Optional: Environment variables
  "python_version": "3.11",                               // Optional: Python version (3.11/3.12)
  "pip_config_file": "./pip.conf",                        // Optional: pip configuration
  "dockerfile_lines": []                                  // Optional: Additional Dockerfile commands
}
