Install CCF

Requirements

CCF builds and runs on Linux. It is primarily developed and tested on Ubuntu 20.04, with Clang 10. Running CCF with full security guarantees requires SGX hardware with FLC.

Note

A virtual version of CCF can also be run on hardware that does not support SGX. The virtual mode provides no security guarantee and is only useful for development and prototyping.

CCF requires the following dependencies to be first installed on your system:

These dependencies can be conveniently installed using the ansible playbooks in the CCF repository or Install:

$ cd <ccf_path>/getting_started/setup_vm/
$ ./run.sh app-dev.yml

Install

CCF releases are available on the GitHub repository release page.

The CCF Debian package (ccf_<version>_amd64.deb) contains the libraries and utilities to start a CCF service and build CCF applications. CCF can be installed as follows:

# Set CCF_VERSION to most recent release
$ export CCF_VERSION=$(curl -ILs -o /dev/null -w %{url_effective} https://github.com/microsoft/CCF/releases/latest | sed 's/^.*ccf-//')
# Alternatively, set this manually, e.g.
# export CCF_VERSION=1.0.0
$ wget https://github.com/microsoft/CCF/releases/download/ccf-${CCF_VERSION}/ccf_${CCF_VERSION}_amd64.deb
$ sudo apt install ./ccf_${CCF_VERSION}_amd64.deb

Assuming that CCF was installed under /opt, the following commands can be run to verify that CCF was installed successfully:

$ /opt/ccf/bin/cchost --version
CCF host: ccf-<version>

$ /opt/ccf/bin/sandbox.sh

The CCF install notably contains:

  • The cchost binary required to spin up a CCF application

  • The cmake files required to build CCF applications

  • The ansible playbooks required for CCF Development Setup (under getting_started/)

  • Header files and libraries to build CCF applications (under include/ and lib/)

  • A limited set of Python utilities to start a basic CCF service for local testing

  • Various utility scripts (see End-to-end demo)

Uninstall

To remove an installation of CCF, run:

$ sudo apt remove ccf
