[KubeCon NA 2020] containerd: Rootless Containers 2020Akihiro Suda
Â
Rootless Containers means running the container runtimes (e.g. runc, containerd, and kubelet) as well as the containers without the host root privileges. The most significant advantage of Rootless Containers is that it can mitigate potential container-breakout vulnerability of the runtimes, but it is also useful for isolating multi-user environments on HPC hosts. This talk will contain the introduction to rootless containers and deep-dive topics about the recent updates such as Seccomp User Notification. The main focus will be on containerd (CNCF Graduated Project) and its consumer projects including Kubernetes and Docker/Moby, but topics about other runtimes will be discussed as well.
