Deploy TEE program on WeTEE

Prepare machines that support SGX

CPU Support

• Intel 8th generation (Cannon Lake) Core i3, i5, i7, and i9 processors

• Intel 9th generation (Cascade Lake) Core i3, i5, i7, and i9 processors

• Intel 10th generation (Comet Lake) Core i3, i5, i7, and i9 processors

• 2nd Generation Xeon Scalable processors (Cascade Lake) and later generations generally provide - SGX capabilities.

Install Ubuntu 20.04/22.04 and the ego programming environment

1. Install base pkg

sudo apt install curl build-essential libssl-dev

2. Install sgx repp key

sudo curl -s https://download.01.org/intel-sgx/sgx_repo/ubuntu/intel-sgx-deb.key | sudo tee /etc/apt/keyrings/intel-sgx-keyring.asc > /dev/null
sudo echo "deb [signed-by=/etc/apt/keyrings/intel-sgx-keyring.asc arch=amd64] https://download.01.org/intel-sgx/sgx_repo/ubuntu focal main" | sudo tee /etc/apt/sources.list.d/intel-sgx.list

3. Install sgx driver

sudo apt-get update && sudo1 apt-get install -y libsgx-dcap-ql libsgx-dcap-default-qpl  libsgx-enclave-common 

sudo mkdir -p /etc/apt/keyrings
wget -qO- https://download.01.org/intel-sgx/sgx_repo/ubuntu/intel-sgx-deb.key | sudo tee /etc/apt/keyrings/intel-sgx-keyring.asc > /dev/null
echo "deb [signed-by=/etc/apt/keyrings/intel-sgx-keyring.asc arch=amd64] https://download.01.org/intel-sgx/sgx_repo/ubuntu $(lsb_release -cs) main" | sudo tee /etc/apt/sources.list.d/intel-sgx.list
sudo apt update
EGO_DEB=ego_1.5.3_amd64_ubuntu-$(lsb_release -rs).deb
wget https://github.com/edgelesssys/ego/releases/download/v1.5.3/$EGO_DEB
sudo apt install ./$EGO_DEB build-essential libssl-dev

Initialize a Golang project

go mod init xxx/ego-demo

Add SGX SDK to the project

go get github.com/wetee-dao/libos-entry@v0.1.0

Write demo code named hello

package main

import (
	"net/http"

	"github.com/wetee-dao/libos-entry/entry/ego"
)

func main() {
	// ADD TEE sdk
	err := ego.InitEgo()
	if err != nil {
		panic(err)
	}

	http.HandleFunc("/", resourceHandler)
	err = http.ListenAndServe(":8999", nil)
	if err != nil {
		panic(err)
	}
}

func resourceHandler(w http.ResponseWriter, req *http.Request) {
	w.WriteHeader(http.StatusOK)
	w.Write([]byte("hello world"))
}

Compile into a binary program

ego-go build hello.go

Sign the binary program

ego sign hello

Run the program using ego

ego run hello

Edit Dockerfile and build docker

FROM registry.cn-hangzhou.aliyuncs.com/wetee_dao/ego-ubuntu-deploy:22.04
WORKDIR /

# Add the hello 
ADD hello  /hello
# Add the hello end

EXPOSE 8999 65535

ENTRYPOINT ["/bin/sh", "-c" ,"ego run hello"]

docker build xxxx/ego-hello:dev .
docker push xxxx/ego-hello:dev
