Thanks for this report. Looks like there is a difference in the oci spec. Which docker version is this? It works correctly on 17.05 for me.

$ docker version

Also if you could check to see if there is a config.json at /var/run/containerd/677dbdda10bab368e63fc641c96d1367230294170d2cb930e8030c985a469c9d/config.json and paste it here it would be helpful.

Thanks

this config.json is generate by using runc runtime

vishvananda commented 7 years ago

thanks. It looks like capabilities changed from a list into a map of lists. Will update.

vishvananda commented 7 years ago

The linked pr fixes the issue you are seeing. Unfortunately docker 17.06 switched to making the oci backend create the pseudo-terminal, which railcar doesn't yet support. That will be added next, but in the meantime, if you want to actually use the containers stdio with railcar, you should use 17.05

vishvananda commented 7 years ago

The pr also adds support for the updated seccomp configuration and console-socket. Everything should work properly for docker 17.06 now. Please remember to pass -t to docker run in order to give it access to the process' console.
