How to debug confidential containers securely

This article discusses how to securely debug workloads running in confidential containers (CoCo) in cloud-native environments, particularly utilizing Kubernetes. It highlights the challenges of debugging without violating the security principles of CoCo, where cluster administrators are considered untrusted. The article presents four approaches that developers can take to debug without exposing sensitive data, including deploying a new pod with a relaxed policy, using logging sidecars, and leveraging SSH access with strict policies. It emphasizes the trade-offs of each method to maintain security while enabling effective debugging.
