Run gRPC TLS C++ Client/Server on Occlum

Step 1:

Downlaod, build and install openssl into /usr/local/occlum/x86_64-linux-musl/lib:

./download_and_install_openssl.sh

Step 2:

Download, build and install cares, protobuf and finally gRPC into /usr/local/occlum/x86_64-linux-musl/lib:

./download_and_install_grpc.sh

Step 3:

Prepare the gRPC TLS C++ Hello World demo Occlum instance, which consists of a client and server:

./prepare_occlum_instance.sh

Then you can see two occlum instance created for server(occlum_server) and client(occlum_client).

Step 4:

Start tls server which will listen on port 50051 on occlum:

cd occlum_server
occlum run /bin/greeter_secure_server

Then you can invoke gRPC service by running tls client in a different terminal on occlum:

cd occlum_client
occlum run /bin/greeter_secure_client

And you will see the "Greeter received: Hello world" in the client side output.
