Photon is not an "app" that you "install", and that tarball is just the source code, equivalent to git clone
ing the main repo. The docker image is for a prebuilt server.
Here's what thearch said on how to run the server yourself:
You'll need node.js and npm for the minimum node server.
- Run npm install to fetch the dependencies.
- Build the app with ADAPTER=node npm run build
- There should be a new directory, build.
- To run the app, do node build/index.js. You can set the documented environment variables, and use PORT= to change the port.
