Prerequisite

Install enable_RDFSBASE Kernel Module

If the Kernel version is before v5.9, please follow this README to install enable_rdfsbase kernel module.

Install Occlum with APT on Ubuntu 20.04

  1. Install Intel® SGX Driver and Intel® SGX PSW

Please follow Intel SGX Installation Guide to install SGX driver and SGX PSW. SGX SDK is not required. Using PSW installer is recommanded.

To install PSW, follow the guide to add Intel® SGX repository to APT source. And then run:

apt-get update
apt-get install -y libsgx-dcap-ql libsgx-epid libsgx-urts libsgx-quote-ex libsgx-uae-service libsgx-dcap-quote-verify-dev

apt-get install -y occlum

Occlum toolchains packages

Besides, users can choose to install the toolchain installer based on the application's language. Currently, Occlum supports only musl-gcc, glibc. Users can install each one on demand.

apt install -y occlum-toolchains-gcc
apt install -y occlum-toolchains-glibc

Occlum Runtime package

If users only expect to run the Occlum instance image, then occlum-runtime package is better choice for size reason.

apt install -y occlum-runtime
