Dotnet restore fails when build docker

Question

I have a problem with dotnet restore command used in docker container.

I am using standard Dockerfile generated by VS2022 for simple console project in .net 7. DockerFile is generated by Visual Studio.

Docker Engine v24.0.7 Docker Desktop v4.26.1

DockerFile :

FROM mcr.microsoft.com/dotnet/runtime:7.0 AS base
WORKDIR /app

FROM mcr.microsoft.com/dotnet/sdk:7.0 AS build
ARG BUILD_CONFIGURATION=Release
WORKDIR /src
COPY ["ConsoleApp1.csproj", "."]
#RUN curl -i -k -X GET https://api.nuget.org/v3/index.json 
RUN dotnet restore "./././ConsoleApp1.csproj"
COPY . .
WORKDIR "/src/."
RUN dotnet build "./ConsoleApp1.csproj" -c $BUILD_CONFIGURATION -o /app/build

FROM build AS publish
ARG BUILD_CONFIGURATION=Release
RUN dotnet publish "./ConsoleApp1.csproj" -c $BUILD_CONFIGURATION -o /app/publish /p:UseAppHost=false

FROM base AS final
WORKDIR /app
COPY --from=publish /app/publish .
ENTRYPOINT ["dotnet", "ConsoleApp1.dll"]

Output :

docker build -f Dockerfile --force-rm -t consoleapp1:dev --target build .

I try this request from container and I could hit nuget :

curl -v -k https://api.nuget.org/v3/index.json

I try severals solutions (link) posted in stackoverflow and the web but I have same issue...

UPDATE 1 :

I fixed the problem, my company use a proxy. We have disabled the proxy for tests and dotnet restore command not failed. All I have to do is import my company certificate in the container.

UPDATE 2 :

Import certificates and update :

...

ARG BUILD_CONFIGURATION=Release
WORKDIR /src
COPY ["ConsoleApp1.csproj", "."]
COPY ["./Certificate/myCertificate.crt", "/usr/local/share/ca-certificates/myCertificate.crt"]
