I'm trying to add docker to template angular spa with .NET Core 2.0. I added docker support with Visual Studio 2017 and when I launch the application with docker-compose I have an error in

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

This is the exception:

One or more errors occurred. (Failed to start Node process. To resolve this:.\n\n[1] Ensure that Node.js is installed and can be found in one of the PATH directories.\n Current PATH environment variable is: /usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin\n Make sure the Node executable is in one of those directories, or update your PATH.\n\n[2] See the InnerException for further details of the cause.)

The dockerfile has:

FROM microsoft/aspnetcore:2.0 AS base
WORKDIR /app
EXPOSE 80

I've modified the Dockfile with:

FROM microsoft/aspnetcore:2.0 AS base
RUN curl -sL https://deb.nodesource.com/setup_8.x
RUN bash -
RUN apt-get -y update
RUN apt-get install -y build-essential nodejs
RUN ln -s /usr/bin/nodejs /usr/bin/node
WORKDIR /app
EXPOSE 80

When I launch Dockercompose I have the following error on the same line:

System.AggregateException

  Message=One or more errors occurred. (Unexpected token {

Of course i'd like to use HMR with webpack and Docker
