Unauthorized: authentication required


(Salam Y. ELIAS) #1

Since a couple of days, I am trying to build a docker file but always getting unauthorized: authentication required.

Here is the contents of the Dockerfile:

FROM microsoft/aspnet

# Download and extract BlogEngine.NET project files

RUN powershell -Command
$ErrorActionPreference = ‘Stop’;
Invoke-WebRequest -Method Get -Uri https://blogengine.codeplex.com/downloads/get/1566660 -OutFile c:\BlogEngineNETSrc.zip ;
Expand-Archive -Path c:\BlogEngineNETSrc.zip -DestinationPath c:\inetpub\wwwroot\blogengine ;
Remove-Item c:\BlogEngineNETSrc.zip -Force

Configure Web App

COPY buildapp.ps1 C:/
RUN powershell.exe C:\buildapp.ps1

#FIX DNS issues currently in Windows Containers
RUN powershell set-itemproperty -path ‘HKLM:\SYSTEM\CurrentControlSet\Services\Dnscache\Parameters’ -Name ServerPriorityTimeLimit -Value 0 -Type DWord

Overwrite Web.config file so that web service points to db service

COPY Web.config C:/inetpub/wwwroot/blogengine
EXPOSE 81

Download starts, some completes then I see

In fact, it seems that "Docker for Windows " was corrupt, maybe because of the different upgrades since 2 years. I removed it completely and re-installed it, in Windows containers mode everything works fine but not Linux containers mode. It crashes. I opened a thread at https://github.com/docker/for-win/issues/1589#issuecomment-359322046
since 3 days but no response yet from the team

For some reason, your docker daemon tries to authenticate yourself to docker hub. This happens only with a layer of the docker image.

This is an old discussion but, I’ve encountered an issue like this and I’ve solved logging out from docker windows application.
