title: Add specific JRE to .Net Dockerfile
body: <p>I'm setting up a .net Docker image, with some .net code within it. The code, however, needs access to a very specific version of Java Runtime (<code>jre-7u9-windowsx64.exe</code>). </p>
  
  <p>I don't know exactly where to start in adding this executable into my dotnet Dockerfile.</p>
  
  <p>The current Dockerfile for dotnet</p>
  
  <pre><code>FROM mcr.microsoft.com/dotnet/core/sdk:2.2 AS build-env
  WORKDIR /name
  
  # Copy csproj and restore as distinct layers
  COPY *.csproj ./
  RUN dotnet restore
  
  # Copy everything else and build
  COPY . ./
  RUN dotnet publish -c Release -o out
  
  # Build runtime image
  FROM mcr.microsoft.com/dotnet/core/aspnet:2.2
  WORKDIR /app
  COPY --from=build-env /app/out .
  ENTRYPOINT ["dotnet", "name.dll"]
  </code></pre>
  
  <p>I would just like to get the JRE added to the Dockerfile so it is installed or available when Docker spins up.</p>
