Possible Solution

Steps to Reproduce (for bugs)

1. look at doc
2. modify the net-conf.json section and deploy linux flannel
3. get flannel for window yaml
4. use Dockerfile to build latest version docker image and use this version image to deploy the flannel for windows
5. the pod will occurred error

the microsoft official doesn't provide the v0.21.5 image. so i build the latest image with Dockerfile,but it occurred the error

[jidaojiuyou]

when i use the Dockerfile to build v0.21.5 image, it works.

what‘s trouble with the v0.25.1 flanneld.exe ?

[rbrtbnfgl]

@manuelbuil Do you have any idea on this?

[manuelbuil]

Not really, it is working in my env but I am executing flanneld directly, not using the Dockerfile or guide mentioned in this issue. That one belongs to sig-windows and it was never tested in Flannel, so it might be that it is outdated, but this is just a guess 🤷
