inclavare-containers is a set of tools for running trusted applications in containers with the hardware-assisted enclave technology. Enclave, referred to as a protected execution environment, prevents the untrusted entity from accessing the sensitive and confidential assets in use.
rune is a CLI tool for spawning and running enclaves in containers according to the OCI specification. The codebase of
rune is a fork of runc, so
rune can be used as
runc if enclave is not configured or available.
rune currently supports the Linux platform with x86-64 architecture only. It must be built with Go version 1.14 or higher.
rune depends on protobuf compiler. Please refer to this guide to install it on your platform. Additionally,
rune by default enables seccomp support as runc so you need to install libseccomp on your platform. Note that the libseccomp is also required in container environment, and the host version should be equal or higher than the one in container.
# create $WORKSPACE folder mkdir -p "$WORKSPACE" cd "$WORKSPACE" git clone https://github.com/alibaba/inclavare-containers cd inclavare-containers/rune # install Go protobuf plugin for protobuf3 go get firstname.lastname@example.org # build and install rune make sudo make install
rune will be installed to
/usr/local/sbin/rune on your system.
shim-rune resides in between
rune, conducting enclave signing and management beyond the normal
rune can compose a basic enclave containerization stack for the cloud-native ecosystem. Please refer to this guide for the details.
The backend of
rune is a component called enclave runtime, which is responsible for loading and running protected applications inside enclaves. The interface between
rune and enclave runtime is Enclave Runtime PAL API, which allows invoking enclave runtime through well-defined functions. The software for confidential computing may benefit from this interface to interact with OCI runtime.
One typical class of enclave runtime implementations is based on library OSes. Currently, the default enclave runtime interacting with
rune is Occlum, a memory-safe, multi-process library OS for Intel SGX.
In addition, you can write your own enclave runtime with any programming language and SDK (e.g, Intel SGX SDK) you prefer as long as it implements Enclave Runtime PAL API.
sgx-tools is a commandline tool, used to interact Intel SGX aesm service to retrieve various materials such as launch token, Quoting Enclave's target information, enclave quote and enclave remote attestation report from IAS. Refer to this guide for the details about its usage.
Please refer to this doc for the details.
Please refer to this guide to run
Skeleton is an example of enclave runtime, interfacing with Enclave Runtime PAL API for easy interfacing with
rune. Skeleton sample code is helpful to write your own enclave runtime.

Reference container image
The reference container images are available for the demonstration purpose to show how a Confidential Computing Kubernetes Cluster with Inclavare Containers works. Currently, web application demos based on OpenJDK 11, Dragonwell, and Golang are provided.
