@Random-Liu - Working on getting the CLA signed. |
It seems that the library we are using already supported windows. https://github.com/kubernetes/kubernetes/tree/master/pkg/kubelet/util @jterry75 Doesn't it work? And I think the dockershim windows support today is using that. |
@Random-Liu - Only supports TCP see util_windows.go#L48. Given that CRI is local only it should use npipe on Windows. |
@jterry75 I see. If containerd is going to provide npipe on Windows, we should eventually update the kubelet util library to support it, thus kubelet can use it. But I'm fine with starting from crictl/critest for development first. :) /cc @feiskyer who knows more about windows. Does |
@Random-Liu - I pushed and update that keep the old behavior if indeed people need tcp support for crictl on Windows. This will just inspect the EP and return an dialer for NamedPipes if the EP is a pipe path otherwise uses the util package as it used to. |
dockershim on Windows listens to We should update util package to support both tcp and npipe on Windows, so that containerd would work for kubelet. |
@feiskyer - I can update it there that's fine. This change would support both tcp and npipe on Windows now though. Do you see any issues with that? |
@feiskyer @Random-Liu Here is a change in my private fork of Kubernetes as well: jterry75/kubernetes:a2f144. I assume this is the right long term solution that you were looking for? |
@feiskyer - Changes the default to tcp as you requested but leaves support for npipe |

@feiskyer - PTAL. Rebased on latest master and added comments as requested. I will also make these comments when updating the kubernetes repo as they don't have any currently. |
