问题
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
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"
When I run command
docker-compose -f "docker-compose.yml" build
I have a error
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
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.
回答1:
I had a similar problem. It's works for me:
- Add curl command to dockerfile before restore:
- RUN curl https://api.nuget.org/v3/index.json -k
- RUN dotnet restore "AuthAPI/AuthAPI.csproj"
- Build image
- Remove curl command from dockerfile
- Build image again
