Attestation Agent (aka AA) is a service for the attestation procedure in Confidential Computing. It provides several kinds of service APIs related to attestation.

This repository packages AA into an easy-to-use image.

Build Image

# download the source
git clone --recurse-submodules \
    https://github.com/inclavare-containers/attestation-agent.git && \
    cd attestation-agent

# build AA image with gRPC interface
make build-grpc

# build AA image with ttrpc interface
make build-ttrpc

In order to build AA with the specific commit, please set the environment variable AA_COMMIT to build. Run make help to get the full help information.
