Nodejs not part of docker in Getting Started Template for JSS to work

Question

Nodejs is a pre-requisite for Sitecore 10 JSS and after setting up the solution for JSS with Getting started template https://doc.sitecore.com/developers/100/developer-tools/en/walkthrough--using-the-getting-started-template.html, an error is shown is experience editor on wiring up the react JSS app.

Is there a suitable option for Sitecore Docker so Nodejs is part of the setup?

Experience editor shows the following exception:

Error Rendering Sitecore.JavaScriptServices.ViewEngine.Presentation.JsLayoutRenderer: 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 environment variable is: C:\Windows\system32;C:\Windows;C:\Windows\System32\Wbem;C:\Windows\System32\WindowsPowerShell\v1.0;C:\Windows\System32\OpenSSH;C:\Windows\system32\config\systemprofile\AppData\Local\Microsoft\WindowsApps Make sure the Node executable is in one of those directories, or update your PATH. [2] See the InnerException for further details of the cause.

Answer 1

Add this at the end of dockerfile

# Download node package we want and unzip to one of search paths
RUN curl.exe -o node.zip https://nodejs.org/dist/v12.14.0/node-v12.14.0-win-x64.zip
RUN tar.exe -xf node.zip -C "C:\Windows" --strip-components=1

Answer 2

It's located in the test folder from the docker-images repo. There is an example to show you how to do that. https://github.com/Sitecore/docker-images/blob/master/build/windows/tests/10.0.x/build/jss-integrated-mode/Dockerfile

There are scenarios where people may prefer to use their own rendering engine instead of integrated mode.
