## 🔄 Add Template Migration to CLI ### Summary This PR introduces a new `migrate` command to the E2B CLI that helps users transition from the legacy Dockerfile + TOML configuration format to the new Template SDK format. The migration tool automatically converts existing `e2b.Dockerfile` and `e2b.toml` configurations into SDK-compatible template files using Handlebars templates. ### What's Changed #### ✨ New Features - **Template Migration Command**: Added `e2b template migrate` command for converting legacy configurations to SDK format - **Multi-Language Support**: Supports migration to TypeScript, Python (sync), and Python (async) formats - **Interactive Language Selection**: CLI prompts for target language when not specified - **Multi-stage Dockerfile Support**: Added fallback handling for complex multi-stage Dockerfiles #### 🔧 Technical Improvements - **Enhanced ENV Handling**: Improved parsing of multiple environment variables from single ENV instructions - **File Name Conflict Resolution**: Automatic unique filename generation to prevent overwriting existing files - **Comprehensive Template Generation**: Creates both development and production build files #### 📁 New Template Files - `typescript-template.hbs` - TypeScript template generation - `typescript-build.hbs` - TypeScript build script template - `python-template.hbs` - Python template generation (supports both sync/async) - `python-build-async.hbs` - Python async build script template - `python-build-sync.hbs` - Python sync build script template ### Usage ```bash # Migrate with interactive language selection e2b template migrate # Migrate to specific language e2b template migrate --language typescript e2b template migrate --language python-sync e2b template migrate --language python-async # Custom paths e2b template migrate --dockerfile custom.dockerfile --config custom.toml ``` ### Generated Output The migration command generates three files per target: - `template.{ts|py}` - Template definition using SDK - `build{.|_}dev.{ts|py}` - Development build script - `build{.|_}prod.{ts|py}` - Production build script ### Migration Process 1. **Parse Configuration**: Reads `e2b.toml` for template settings 2. **Dockerfile Analysis**: Uses E2B SDK to parse Dockerfile instructions 3. **Transformation**: Converts Docker instructions to SDK method calls 4. **Code Generation**: Uses Handlebars templates to generate target language files 5. **File Creation**: Writes template and build files with conflict resolution ### Error Handling - **Graceful Dockerfile Parsing**: Falls back to custom image reference for unparseable Dockerfiles - **Clear User Guidance**: Provides manual build instructions when automatic conversion fails - **Validation**: Ensures required configuration files exist before migration
What is E2B?
E2B is an open-source infrastructure that allows you to run AI-generated code in secure isolated sandboxes in the cloud. To start and control sandboxes, use our JavaScript SDK or Python SDK.
Run your first Sandbox
1. Install SDK
pip install e2b-code-interpreter
2. Get your E2B API key
E2B_API_KEY=e2b_***
3. Execute code with code interpreter inside Sandbox
from e2b_code_interpreter import Sandbox
with Sandbox.create() as sandbox:
sandbox.run_code("x = 1")
execution = sandbox.run_code("x+=1; x")
print(execution.text) # outputs 2
