I am using Azure DevOps Pipelines to create a Docker image from my github repo. It is having issue however accessing the nuget package that I have hosted in Azure Artifacts. It returns unauthorized (401). As Azure Pipelines seems to be relativly new, there does not seem to be much help, and the help that is out there that is not specifically for Artifacts has not worked for me.

azure-pipelines.yml

pool:

  vmImage: 'Ubuntu 16.04'



variables:

  imageName: 'dockerRepoName:$(build.buildId)'



steps:

- script: docker build -f dockerRepoName -t $(imageName) .

  displayName: 'docker build'

Dockerfile

FROM microsoft/dotnet:2.1-sdk AS build

WORKDIR /src

COPY MyWebsite.Website/MyWebsite.Website.csproj MyWebsite.Website/

COPY NuGet.config ./

RUN dotnet restore MyWebsite.Website/MyWebsite.Website.csproj

COPY . .

WORKDIR /src/MyWebsite.Website

RUN dotnet build MyWebsite.Website.csproj -c Release -o /app



FROM build AS publish

RUN dotnet publish MyWebsite.Website.csproj -c Release -o /app



FROM base AS final

WORKDIR /app

COPY --from=publish /app .

ENTRYPOINT ["dotnet", "MyWebsite.Website.dll"]

Took out the actual user and passwords, so that obviously was not what I used for those. The urls are also updated to "companyName" since it a private repo so the url will not work.

   • Grant Read access to the Package section of the Scopes
   
   
   
   


2. Modify the dockerfile


3. Specify the PAT build argument as docker build --build-arg PAT="{access token}"
