.NET Core docker image doesn't support JavaScriptServices

[SirwanAfifi]

I have added webpack as part of my project using UseWebpackMiddleware:

app.UseWebpackDevMiddleware(new WebpackDevMiddlewareOptions
{
    HotModuleReplacement = true
});

But once the image is built (docker-compose up) I get following error message in the console:

Unhandled Exception: System.AggregateException: One or more errors occurred. (Failed to start Node process. To resolve this:.

[1] Ensure that Node.js is installed and can be found in one of the PATH directories.
    Current PATH enviroment variable is: /usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin
    Make sure the Node executable is in one of those directories, or update your PATH.

Dockerfile:

# Copy compiled app to runtime container
FROM base AS final
COPY --from=build /app .
CMD ["dotnet", "MyProject.Web.dll"]

Any idea?
