Dotnet还原码头失败

Question

Docker和命令dotnet还原存在问题。我有码头文件：

FROM mcr.microsoft.com/dotnet/core/aspnet:3.1-buster-slim AS base
WORKDIR /app
EXPOSE 80
EXPOSE 443

FROM mcr.microsoft.com/dotnet/core/sdk:3.1-buster AS build
WORKDIR /src
COPY ["AuthAPI/AuthAPI.csproj", "AuthAPI/"]
COPY ["CommonCoreLibrary/CommonCoreLibrary.csproj", "CommonCoreLibrary/"]
RUN dotnet restore "AuthAPI/AuthAPI.csproj"
COPY . .
WORKDIR "/src/AuthAPI"
RUN dotnet build "AuthAPI.csproj" -c Release -o /app/build

FROM build AS publish
RUN dotnet publish "AuthAPI.csproj" -c Release -o /app/publish

FROM base AS final
WORKDIR /app
COPY --from=publish /app/publish .
COPY wait /wait
RUN chmod +x /wait
COPY /cert /root/.dotnet/https
ENTRYPOINT /wait && dotnet AuthAPI.dll

并编写文件：

  authapi:
    image: ${DOCKER_REGISTRY-}authapi
    build:
      context: .
      dockerfile: AuthAPI/Dockerfile
    networks:
      - peopleapp
    environment:
      WAIT_HOSTS: db:5432
      WAIT_HOSTS_TIMEOUT: 300
    ports:
      - "8002:443"

当我运行命令

docker-compose -f "docker-compose.yml" build

我有个错误

Step 10/23 : RUN dotnet restore "AnalyticAPI/AnalyticAPI.csproj"
 ---> Running in 2d29e1367d51
  Determining projects to restore...
/usr/share/dotnet/sdk/3.1.300/NuGet.targets(128,5): error : Unable to load the service index for source https://api.nuget.org/v3/index.json. [/src/AnalyticAPI/AnalyticAPI.csproj]

ERROR: Service 'analyticapi' failed to build: The command '/bin/sh -c dotnet restore "AnalyticAPI/AnalyticAPI.csproj"' returned a non-zero code: 1

有时效果很好。有关于连接被拒绝的警告，但恢复就是成功。我使用Windows 10 +Hyper+ Desktop + Linux容器+NetCore3.1.

我也有过类似的问题。对我来说很管用：

在restore:

• RUN curl -k
• RUN dotnet还原"AuthAPI/AuthAPI.csproj"

1. Build图像
2. 之前向dockerfile添加curl命令，再次从dockerfile
3. Build图像中删除curl命令
