我有一个ASP.net核心Web APP，并希望通过devops IC进行构建，但是这里出现错误:步骤12/13:COPY --from = build-env / app / out。
标志值build-env中的值无效:build-env的拉取访问被拒绝，存储库不存在或可能需要“docker登录”
像这样的dockerfile:
#Depending on the operating system of the host machines(s) that will build or run the containers, the image specified in the FROM statement may need to be changed.
#For more information, please see https://aka.ms/containercompat
FROM microsoft/dotnet:2.1-aspnetcore-runtime-nanoserver-1809 AS base
WORKDIR /app
EXPOSE 80
FROM microsoft/dotnet:2.1-sdk-nanoserver-1809 AS build
WORKDIR /src
# Copy csproj and restore as distinct layers
COPY *.csproj ./
RUN dotnet restore
# Copy everything else and build
COPY . ./
RUN dotnet publish -c Release -o out
# Build runtime image
FROM base AS final
WORKDIR /app
COPY --from=build-env /app/out .
ENTRYPOINT ["dotnet", "AzureIoTEdgeWebAPI.dll"]谢谢你的帮助。
有输出消息

##[section]Finishing: Build an image最佳答案
在此行build-env之前，我看不到任何引用COPY --from=build-env /app/out .的内容，而是看到了对build的引用。我认为将该行更改为COPY --from=build /app/out .应该可以解决您的问题。
关于azure - 生成器拒绝Azure DevOps CI拉访问，存储库不存在或可能需要 'docker login'，我们在Stack Overflow上找到一个类似的问题：https://stackoverflow.com/questions/57067970/
