## Usage

- [Dstack-TEE: Dstack](https://github.com/Dstack-TEE/dstack)
- Bun for runtime and package management
- TypeScript for type safety
- Commander.js for CLI interface
- Zod for runtime validation

## 🚀 Quick Start (5 Minutes)

1. **Install Prerequisites**:
   ```bash
   # Install Bun
   curl -fsSL https://bun.sh/install | bash
   
   # Verify Docker is installed
   docker --version
   ```

2. **Install TEE Cloud CLI**:

   Install via npm or use npx/bunx
   ```bash
   # Install the CLI globally
   npm install -g phala
   ```

   > **NOTE**
   >
   > You can use `npx` or `bunx` to call the `phala` command
   >
   > ```bash
   > # Use npx/bunx
   >
   > npx phala help
   > bunx phala help
   > ```
   
   ```bash
   # Phala CLI help menu
   npx phala help
   ```

3. **Sign Up and Get API Key**:
   
   To deploy applications to Phala Cloud, you'll need an API key:

   - Visit [Phala Cloud](https://cloud.phala.network/login) to log into your Phala Cloud account. If you do not have an account, register with this link with [PROMO_CODE](https://cloud.phala.network/register?invite=PHALACLI) or run `npx phala free` in the terminal.
   - After logging in, navigate to the "API Keys" section in your profile
   - Create a new API key with an appropriate name (e.g., "CLI Access")
   - Copy the generated API key - you'll need it for authentication
   - You can verify your API key using:
     ```bash
     phala auth login [your-phala-cloud-api-key]
     phala auth status
     ```

4. **Deploy Your First Confidential App**:
   Clone the [Dstack Examples](https://github.com/Dstack-TEE/dstack-examples) repo and cd into the webshell directory
   ```bash
   git clone https://github.com/Dstack-TEE/dstack-examples.git && cd dstack-examples/webshell
   ```
   
   ```bash
   # Deploy the webshell Dstack example
   phala cvms create
   ```

   Provide a name and select from the drop down of examples

   ```bash
   # ? Enter a name for the CVM: webshell
   # ℹ Detected docker compose file: ./docker-compose.yml

   # ? Enter the path to your Docker Compose file:(docker-compose.yml)
   #   ✔ Enter number of vCPUs (default: 1): 1

   #   ✔ Enter memory in MB (default: 2048): 2048

   #    ℹ phala cvms status e15c1a29a9dfb522da528464a8d5ce40ac28039f
   ```

   Now interact with your application in Phala Cloud by going to the url on port 7681 (Example of what a url at port 7681 would look like https://e15c1a29a9dfb522da528464a8d5ce40ac28039f-7681.dstack-prod5.phala.network)

5. **Check the CVM's Attestation**:
   ```bash
   phala cvms attestation

   # ℹ No CVM specified, fetching available CVMs...
   # ⟳ Fetching available CVMs... ✓
   # ✔ Select a CVM: testing (88721d1685bcd57166a8cbe957cd16f733b3da34) - Status: running

## 🏗️ Development Workflow

### 1️⃣ Local Development

Develop and test your application locally with the built-in TEE simulator:

```bash
# Start the TEE simulator
phala simulator start

# Build your Docker image
phala docker build --image my-tee-app --tag v1.0.0

# Create an environment file
echo "API_KEY=test-key" > .env
echo "DEBUG=true" >> .env
```

### 2️⃣ Cloud Deployment

Deploy your application to Phala's decentralized TEE Cloud:

```bash
# Set your Phala Cloud API key
phala auth login

# Login to Docker and Push your image to Docker Hub
phala docker login
phala docker build --image my-tee-app --tag v1.0.0
phala docker push --image my-tee-app --tag v1.0.0

# Deploy to Phala Cloud
phala cvms create --name my-tee-app --compose ./docker-compose.yml --env-file ./.env

# Access your app via the provided URL
```

## 🛠️ Advanced Features

### Docker Compose Templates

> This feature is still being developed. Best to build your own docker-compose file for now.

(WIP) Choose from docker compose file for your application:

```bash
phala docker generate --image my-app --tag v1.0.0 --env
```

### Customizing Resource Allocation

Resize specific resources for your existing CVM:

```bash
phala cvms resize e15c1a29a9dfb522da528464a8d5ce40ac28039f --name resource-intensive-app --compose ./compose.yml \
  --vcpu 4 --memory 8192 --disk-size 50 -r true -y
```

### Environment Variables Management

```bash
# Using env file
phala cvms create --name env-app --compose ./compose.yml --env-file ./.env
```


## 🔒 Security

The TEE Cloud CLI employs several security measures:

1. **Encrypted Credentials**: API keys and Docker credentials are stored with encryption using a machine-specific key
2. **Restricted Permissions**: All credential files are stored with 0600 permissions (user-only access)
3. **No Validation Storage**: API keys are not validated during login, preventing unnecessary transmission
4. **Local Storage**: All credentials are stored locally in the `~/.phala-cloud/` directory

## 🔍 Troubleshooting

Common issues and solutions:

1. **Docker Build Fails**
   - Verify Docker daemon is running
   - Check Dockerfile path
   - Ensure proper permissions

2. **Simulator Issues**
   - Check if port 8090 is available
   - Verify Docker permissions

3. **Cloud Deployment Fails**
   - Validate API key
   - Confirm image exists on Docker Hub
   - Check environment variables
