What are Confidential Containers?
Confidential Containers (CoCo) is a new sandbox project of the Cloud Native Computing Foundation (CNCF) that enables cloud-native confidential computing by taking advantage of a variety of hardware platforms and technologies. The project brings together software and hardware companies including Alibaba-cloud, AMD, ARM, IBM, Intel, Microsoft, Red Hat, Rivos and others.
The CoCo project builds on existing and emerging hardware security technologies such as Intel SGX, Intel TDX, AMD SEV and IBM Z Secure Execution, in combination with new software frameworks to help better secure user data in use. This will establish a new level of confidentiality, which does not rely on trust in the cloud providers and their employees, but on hardware-level cryptography. CoCo will support multiple environments including public clouds, on-premise and edge computing.
The goal of the CoCo project is to standardize confidential computing at the container level and simplify its consumption in Kubernetes. This is in order to enable Kubernetes users to deploy confidential container workloads using familiar workflows and tools without extensive knowledge of underlying confidential computing technologies.

This article describes the hardware-based attestation flows and processes that the Confidential Containers project is built upon. With hardware-based attestation, a confidential computing processor generates cryptographic evidence for a workload-running environment. Provided that the workload owner trusts that piece of hardware, they can then remotely verify that evidence and decide if the workload’s execution environment is trustworthy or not…Read full post

The CoCo community recognizes that not every developer has access to TEE-capable machines and we don't want this to be a blocker for contributions. So version 0.1.0 and later come with a custom runtime that lets developers play with CoCo on either a simple virtual or bare-metal machine. In this tutorial you will learn: How to install CoCo and create a simple confidential pod on Kubernetes, and the main features that keep your pod confidential…Read full post
