Docker. Its how any software can be packaged with its dependencies. Best for linux serverside/webapp software.

Install and run a docker with one console command, just provide a network-port and folder mapping.

Or use a webinterface, i like how Unraid does this. If you have a old server/PC to spare, definitely try Unraid.net by just booting it from USB stick.
