🛠️Phala Cloud CLI Reference

A command-line tool for managing Trusted Execution Environment (TEE) deployments on Phala Cloud, from local development to cloud deployment.

Phala Command Line Interface (CLI) Reference

Usage

• 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)

Install Prerequisites:

# Install Bun
curl -fsSL https://bun.sh/install | bash

# Verify Docker is installed
docker --version

Install TEE Cloud CLI:

Install via npm or use npx/bunx

# Install the CLI globally
npm install -g phala

NOTE

# Use npx/bunx

npx phala help
bunx phala help

You can use npx or bunx to call the phala command

# Phala CLI help menu
npx phala help

Sign Up and Get API Key:

To deploy applications to Phala Cloud, you'll need an API key:

• Visit Phala Cloud to log into your Phala Cloud account. If you do not have an account, register with this link with PROMO_CODE.

• 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:

  phala auth login [your-phala-cloud-api-key]
  phala auth status

#   ℹ App ID: e15c1a29a9dfb522da528464a8d5ce40ac28039f
#   ℹ App URL: <https://cloud.phala.network/dashboard/cvms/app_e15c1a29a9dfb522da528464a8d5ce40ac28039f>
#    ℹ
#    ℹ Your CVM is being created. You can check its status with:
#    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)

Check the CVM's Attestation:

🏗️ Development Workflow

1️⃣ Local Development

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

# 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

# Generate and run Docker Compose
phala docker build-compose --image my-tee-app --tag v1.0.0 --env-file ./.env
phala docker run -c ./phala-compose.yaml -e ./.env

2️⃣ Cloud Deployment

Deploy your application to Phala's decentralized TEE Cloud:

# 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

🧩 Project Structure

The Phala Cloud CLI is organized around core workflows:

1. Authentication: Connect to your Phala Cloud account

2. TEEPod Info: Fetch information about TEEPods (TEEPods are where your docker apps deploy to)

3. Docker Management: Build and manage Docker images for TEE

4. TEE Simulation: Local development environment

5. Cloud Deployment: Deploy to production and manage TEE Cloud deployments

📋 Example Dstack Applications

Explore these example dstack applications to understand different use cases for TEE deployment:

• Timelock Encryption: Encrypt messages that can only be decrypted after a specified time

• Light Client: A lightweight blockchain client implementation

• SSH Over TEE Proxy: Secure SSH tunneling through a TEE

• Web Shell: Browser-based secure terminal

• Custom Domain: Deploy with your own domain name

• Private Docker Image: Deploy using private Docker registries

🔒 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
