@hlb-source @cuisongliu Sorry, but we don't have the documentation for it. Could you contribute? It will probably help you. https://github.com/containers/youki/blob/28269200a5b0daf30f3d68c3f675db33bbfcf95a/tests/k8s/Dockerfile#L25-L32

If you are using containerd through docker you can follow this guide: https://docs.docker.com/engine/alternative-runtimes/#youki

@hlb-source I've found that ctr supports a straightforward method for using youki instead of runc.

sudo ctr run -t --runc-binary /path/to/youki docker.io/library/ubuntu:latest youki-hello

You can also verify that it indeed uses youki by executing the command in another shell:

sudo ps auxf | grep -i youki
