Examples

# Interactive mode (prompts for all options)
kernel create

# Create a TypeScript app with the sample template
kernel create --name my-app --language typescript --template sample-app

Next steps

After creating your app:

1. Navigate to the project directory:

   cd my-app

2. Install dependencies:

   • TypeScript: npm install
   • Python: uv venv && source .venv/bin/activate && uv sync

3. Authenticate with Kernel:

   kernel login or export KERNEL_API_KEY=<YOUR_API_KEY>

4. Deploy your app:

   # TypeScript
   kernel deploy index.ts
   
   # Python
   kernel deploy main.py

5. Invoke your app:

   kernel invoke my-app action-name --payload '{"key": "value"}'
