+## Docker Occlum runtime
+
+To run the project in Docker, you need to install the docker first.
+On Ubuntu, you can use the following commands:
+
+```bash
+# Add docker official GPG key
+sudo apt update
+sudo apt install ca-certificates curl
+sudo install -m 0755 -d /etc/apt/keyrings
+sudo curl -fsSL https://download.docker.com/linux/ubuntu/gpg -o /etc/apt/keyrings/docker.asc
+sudo chmod a+r /etc/apt/keyrings/docker.asc
+
+# Add docker repository to apt sources
+echo \
+  "deb [arch=$(dpkg --print-architecture) signed-by=/etc/apt/keyrings/docker.asc] https://download.docker.com/linux/ubuntu \
+  $(. /etc/os-release && echo "$VERSION_CODENAME") stable" | \
+  sudo tee /etc/apt/sources.list.d/docker.list > /dev/null
+sudo apt update
+
+# Install docker packages
+sudo apt install docker-ce docker-ce-cli containerd.io docker-buildx-plugin docker-compose-plugin
+
+# Add your user to the docker group
+sudo groupadd docker
+sudo usermod -aG docker $USER
+newgrp docker
+```
+
+Next run the occlum image in the docker environment:
+
+```bash
+docker run --rm -it --device /dev/sgx/enclave --device /dev/sgx/provision -v /path/to/occlum-ratls:/root/occlum-ratls occlum/occlum:latest-ubuntu20.04
+
+# Inside the docker container do env preparation
+rustup install stable-x86_64-unknown-linux-gnu
+rustup default stable
+rustup target add x86_64-unknown-linux-musl
+# edit /etc/sgx_default_qcnl.conf, so that the PCCS URL is set correctly
+# "pccs_url": "https://api.trustedservices.intel.com/sgx/certification/v4/"
+
+cd /root/occlum-ratls
+./build_server.sh grpcs --run
+
+# In another terminal exec /bin/bash into the same container
+cd /root/occlum-ratls
+./build_client.sh grpcs --run
+```
