When I use crictl,it can not work on my environment.

# crictl info
DEBU[0000] StatusRequest: &StatusRequest{Verbose:true,}
DEBU[0000] StatusResponse: nil
FATA[0000] getting status of runtime failed: rpc error: code = Unimplemented desc = unknown service runtime.v1alpha2.RuntimeService

Seems CRI v1alpha2 is not supported in conatinerd v1.1.0. Maybe upgrade it to a new version?

All of the binaries are make by myself through repos,may be I confused the containerd and cri version.When I download cri-containerd from release tarball and install on redhat:

wget https://storage.googleapis.com/cri-containerd-release/cri-containerd-${VERSION}.linux-amd64.tar.gz

crictl can work now.
Thanks:)

@hmtai Cool!

@Random-Liu may give more details of building containerd.

[Random-Liu]

@hmtai Seems to be a version skew. You are either using an old crictl with new containerd, or old containerd with new crictl.

[hmtai]

Yes,the containerd and crictl version does not match.Actually I build the same containerd crictlversion as above on s390x and crictl can work well.When I build by myself I don't know what version containerd runc crictl should I use that can make them work together.

I think we can close this one.
