In this episode of Linux Server Admin with Fexingo, Lucas and Luna dive into the practical side of container runtimes—specifically, how to choose between Docker, containerd, and Podman for production server workloads. They break down the architecture of each runtime, explain how the Open Container Initiative (OCI) standards ensure interoperability, and walk through a real-world scenario: deploying a Python web app on a bare-metal server using containerd directly (without Docker). Lucas shares a surprising benchmark: containerd can reduce memory overhead by 30-40% compared to a full Docker daemon on lightweight servers. Luna asks about security differences, especially around daemonless architectures and rootless containers. By the end, you'll know when to reach for which runtime and how to test them yourself. Perfect for sysadmins tired of Docker defaults or curious about lower-level container orchestration. Produced by Fexingo Business Podcast Network.
