Confidential Container Tools and Components

This repository includes tools and components for confidential container images.

Components

Attestation Agent An agent for facilitating attestation protocols. Can be built as a library to run in a process-based enclave or built as a process that runs inside a confidential vm.

image-rs Rust implementation of the container image management library.

ocicrypt-rs Rust implementation of the OCI image encryption library.

api-server-rest CoCo Restful API server.

coco-keyprovider CoCo Keyprovider. Used to encrypt the container images.

Build

A Makefile is provided to quickly build Attestation Agent/Api Server Rest/Confidential Data Hub for a given platform.

make build TEE_PLATFORM=$(TEE_PLATFORM)
make install DESTDIR=/usr/local/bin

The TEE_PLATFORM parameter can be

• none: for tests with non-confidential guests
• all: for all following platforms
• fs: for platforms with encrypted root filesystems (i.e. s390x)
• tdx: for Intel TDX
• az-tdx-vtpm: for Intel TDX with Azure vTPM
• sev: for AMD SEV(-ES)
• snp: for AMD SEV-SNP
• amd: for both AMD SEV(-ES) and AMD SEV-SNP
• az-snp-vtpm: for AMD SEV-SNP with Azure vTPM

by default, kbs/sev as a resource provider will be built in Confidential Data Hub. If you do not want enable any default except for only builtin offline-fs-kbc, you can build with NO_RESOURCE_PROVIDER flag set to true.

make build TEE_PLATFORM=$(TEE_PLATFORM) NO_RESOURCE_PROVIDER=true
