Packages required by kpm as a built-in

[marrrcin]

I've tried to build the ASP.NET vNext Starter Web application (default Visual Studio Project) using docker, however the tutorial provided on the site
http://blogs.msdn.com/b/webdev/archive/2015/01/14/running-asp-net-5-applications-in-linux-containers-with-docker.aspx
didn't cover or even mention lots of issues that may occur. Project as simple as the HelloWeb app with barely 3 files inside built correctly, but the Visual Studio project didn't.

The issue was caused by missing npm (also bower and grunt) in the microsoft/aspnet docker package. KPM restored lots of packages and then just threw an exception "Cannot find npm".

Stacktrace:

System.ComponentModel.Win32Exception: ApplicationName='npm', CommandLine='install', CurrentDirectory='/app', Native error= Cannot find the specified file at System.Diagnostics.Process.Start_noshell (System.Diagnostics.ProcessStartInfo startInfo, System.Diagnostics.Process process) [0x00000] in <filename unknown>:0 at System.Diagnostics.Process.Start_common (System.Diagnostics.ProcessStartInfo startInfo, System.Diagnostics.Process process) [0x00000] in <filename unknown>:0 at System.Diagnostics.Process.Start (System.Diagnostics.ProcessStartInfo startInfo) [0x00000] in <filename unknown>:0 at Microsoft.Framework.PackageManager.ScriptExecutor.Execute (Microsoft.Framework.Runtime.Project project, System.String scriptName, System.Func2 getVariable) [0x00000] in <filename unknown>:0 at Microsoft.Framework.PackageManager.RestoreCommand+<RestoreForProject>d__1.MoveNext () [0x00000] in <filename unknown>:0 --- End of stack trace from previous location where exception was thrown --- at System.Runtime.ExceptionServices.ExceptionDispatchInfo.Throw () [0x00000] in <filename unknown>:0 at System.Runtime.CompilerServices.TaskAwaiter1[System.Boolean].GetResult () [0x00000] in <filename unknown>:0 at Microsoft.Framework.PackageManager.RestoreCommand+<ExecuteCommand>d__1.MoveNext () [0x00000] in <filename unknown>:0

I've resolved this issue on my environment by creating custom Dockerfile to build the project. You can it find here:

My environment : Ubuntu 14.0.1 LTS.
