Using Overlaybd in Container

[qi0523]

Is it possible to create a overlaybd‘s container in the privileged container which can use ctr command?

[HileQAQ]

Yes, it is possible. Let's assume that you have prepared the overlaybd environment on the host and mounted containerd.sock and the root directory of containerd (by default /var/lib/containerd) in the container. After that, mount /dev/ to the container and use the overlaybd's container by using the rpull command of our custom version of ctr.
