Weirdly, it seems to be missing an "i" in cni ?

--cni-bin-dir=/opt/cni/bin --cni-cache-dir=/var/lib/cn

Looks like the override file got truncated

I don't think that is the problem, because of i already have started it without any error yet. But after I stoped minikube or restarted the server, I always got this error. For some reason, my system can't start the cri-dockered again

afbjorklund commented 2 years ago

OK, maybe you pasted half the line or something. Can you run the command directly (as root), from the ExecStart ?

It might give some better output, especially if you also add the --log-level debug options to the end of cri-dockerd

/usr/bin/cri-dockerd --log-level debug --network-plugin=cni ... (i.e. all the other options, except for the one with fd://)

I'm facing the same issue with minikube version 1.28.0. Any updates for this issue? Thank you.

tuanaac commented 1 year ago

@marverlous811 I think I found the root cause. When I start minikube with minikube start --driver=none --network-plugin=cni --cni=bridge, then minikube creates the folder /etc/systemd/system/cri-docker.service.d containing a cni-config file (if it does not exist). This file contains the path /usr/bin/cri-dockerd used by systemd to start the service.

And I assume that you also followed the official guide to install cri-dockerd, where the executable file cri-dockerd is actually moved to /usr/local/bin (https://github.com/Mirantis/cri-dockerd#build-and-install). That is the reason why cri-dockerd.service cannot be started. image

To resolve this issue, I copied the executable file cri-dockerd to /usr/bin: sudo cp /usr/local/bin/cri-dockerd /usr/bin/ After that minikube can start normally. I hope this answer helps you.

@afbjorklund I would like to ask you a question. Should minikube takes the path to cri-dockerd from /etc/systemd/system/cri-docker.service?
