Containers have taken off as one of the foundational technologies that enabled cloud native application development and deployment. But despite their widespread adoption through Docker, Kubernetes and other tools, there has been a significant security risk: users have effectively needed root privileges in order to run containers on a host. Recently there have been significant advances to enable “rootless containers” - containers that can be run without requiring root privileges. This talk will use live-coding in Go to illustrate how rootless containers are created, exploring why root was originally required and what has changed to enable rootless operation. This talk assumes that you have some familiarity with how containers are built using namespaces, cgroups and chroot.
