How to Use Linux Namespaces for Process Isolation

What this episode covers

In episode 50 of Linux Server Admin with Fexingo, Lucas and Luna dive into Linux namespaces for process isolation, focusing on the PID and network namespaces. They walk through real commands — unshare, nsenter, ip netns — to show how to create isolated environments without Docker. Lucas shares a story about using namespaces to run a legacy application in isolation on a production server, avoiding the overhead of full containerization. They also cover how to inspect existing namespaces and common pitfalls like namespace leaks. Perfect for sysadmins who want lightweight isolation without pulling in container runtimes. Tune in for practical, copy-paste-ready commands. #Linux #Namespaces #ProcessIsolation #Sysadmin #Bash #ServerEngineering #ContainerSecurity #Unshare #Nsenter #PIDNamespace #NetNS #Tech #Podcast #FexingoBusiness #BusinessPodcast #DevOps #Infrastructure #SystemAdministration Keep every episode free: buymeacoffee.com/fexingo
