问题描述

Docker 和命令 dotnet restore 有问题.我有 docker 文件:

There is problem with Docker and command dotnet restore. I have the docker file:

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

和docker compose文件:

and docker compose file:

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

当我运行命令时

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

我有一个错误

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]
/usr/share/dotnet/sdk/3.1.300/NuGet.targets(128,5): error :   Connection refused [/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

有时它工作正常.有连接被拒绝的警告,但恢复成功.我使用 Windows 10 + Hyper-V + Docker Desktop + Linux Containers + NET Core 3.1.

Sometimes it works fine. There are warning about Connection refused, but restoring is success. I use Windows 10 + Hyper-V + Docker Desktop + Linux Containers + NET Core 3.1.

推荐答案

我遇到了类似的问题.它对我有用:

I had a similar problem. It's works for me:

  1. 在恢复前向 dockerfile 添加 curl 命令:

  • 运行 curl https://api.nuget.org/v3/index.json -k
  • 运行 dotnet 恢复AuthAPI/AuthAPI.csproj"
    1. 构建镜像
    2. 从 dockerfile 中删除 curl 命令
    3. 重新构建镜像
