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
```

Deploy Your First Confidential App: Clone the Dstack Examples repo and cd into the webshell directory

git clone https://github.com/Dstack-TEE/dstack-examples.git && cd dstack-examples/webshell

🛠️ 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:

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

Customizing Resource Allocation

Resize specific resources for your existing CVM:

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

Environment Variables Management

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

🔒 Security

The TEE Cloud CLI employs several security measures:

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

🔍 Troubleshooting

Common issues and solutions:

Docker Build Fails
- Verify Docker daemon is running
- Check Dockerfile path
- Ensure proper permissions
Simulator Issues
- Check if port 8090 is available
- Verify Docker permissions
Cloud Deployment Fails
- Validate API key
- Confirm image exists on Docker Hub
- Check environment variables
