The podman tool manages pods, container images, and containers. It is part of the libpod library, which is for applications that use container pods. Container pods is a concept in Kubernetes. The runC tool is a lightweight, portable implementation of the Open Container Format that provides container runtime. The skopeo command lets you inspect images from container image registries, get images and image layers, and use signatures to create and verify files. Issues addressed include information leakage, man-in-the-middle, and traversal vulnerabilities.
