I have a docker file that essentially looks like this.
FROM mcr.microsoft.com/windows/servercore:1809 as base
SHELL ["powershell", "-Command", "$ErrorActionPreference = 'Stop'; $ProgressPreference = 'SilentlyContinue';"]
RUN iex ((New-Object System.Net.WebClient).DownloadString('https://chocolatey.org/install.ps1')); \
choco install dotnetcore-runtime --version 2.2.6 -y; \
choco install aspnetcore-runtimepackagestore --version 2.2.6 -y
ENV ASPNETCORE_URLS http://*:80
WORKDIR /app
EXPOSE 80
FROM mcr.microsoft.com/dotnet/core/sdk:2.2-nanoserver-1809 AS build
USER Administrator

RUN mkdir "C:\\Program Files\\node" && \
tar.exe -xf C:\\build\\node-v10.7.0-win-x64.zip -C "C:\\Program Files\\node" --strip-components=1
RUN setx /M PATH "C:\Program Files\node;%PATH%"
RUN RMDIR /s /q c:\\build
WORKDIR /src

COPY .nuget/nuget.config .
RUN dotnet restore "something.csproj" --configfile nuget.config
# COPY . .
WORKDIR "/src/something.csproj folder"
RUN dotnet build "something.csproj" -c Release -o /app
FROM build AS publish
RUN dotnet publish "something.csproj" -c Release -o /app
FROM base AS final
WORKDIR /app
COPY --from=publish /app .
copy buildnumber.html /app/wwwroot
ENTRYPOINT ["dotnet", "something.dll"]
the command Copy . . sometimes takes 10 min
The command RUN dotnet build "something.csproj" -c Release -o /app took 25 min with the copy to the /app folder taking 20 min
build 01-Oct-2019 12:04:05 Something.csproj -> C:\app\
build 01-Oct-2019 12:23:26 Removing intermediate container d31f13da795d
Any ideas on why this takes some long and what can be done to optimize?
