What you expected to happen: Pull windows container image and start the pod

How to reproduce it (as minimally and precisely as possible):

• The image is a ASP.NET (full) application built for Windows Container on Windows 10 laptop.
• The image is pushed to Azure Container Image registry. tag: winpoc.azurecr.io/app1:v1
• Deploy with KubeCtl create -f deployoment.yaml:

apiVersion: apps/v1beta1 kind: Deployment metadata: name: asp-windows spec: replicas: 1 strategy: rollingUpdate: maxSurge: 1 maxUnavailable: 1 template: metadata: labels: app: app1 spec: containers:

• name: app1 image: winpoc.azurecr.io/app1:v1

Anything else we need to know:

Also tried pulling the same image from Docker Hub, but getting timeout error.

Looks like it might be https://github.com/moby/moby/issues/32838, for which a fix was submitted to the docker daemon in https://github.com/moby/moby/pull/35924. The issue was the some weird unicode chars were left in the layer, which was causing Golang to fail to open the file. In the linked case, it was files left in the recycle bin.

@alexxie, I'm new on this development & landed with same error as mentioned by you.

• Installed Docker version 18.03.1-ce, build 9ee9f40. the exposed service shows up with External-IP, but could not browse API. any help will be appreciated.

@bublai Our focus is now .net core and Linux container image which seems to be more stable then the Windows container image. I have not received further update on this issue and have'nt tested it further.
