Rootless Containers with Podman

This article provides a security-focused overview of containerization centered on Podman, highlighting its daemonless, rootless design, SELinux enforcement, user namespaces, and OCI standards for portability and reduced attack surface; it contrasts containers with VMs and Docker, discusses container escape risks and mitigations (seccomp, namespaces, capabilities), and offers practical guidance on networking/packet capture requirements, basic commands, Podman Compose, and integrations with Kubernetes and GUI tools to support secure, resilient deployments.
