Learn Docker even if you have a single app. I do the same with a Minecraft server.

• No dependency issues
• All configuration (storage/network/application management) can be done via a single file (compose file)
• Easy roll-backs possible
• Maintain multiple versions of the app while keeping them separate
• Recreate the server on a different server/machine using only the single configuration file
• Config is standardized so easy to read

You will save a huge amount of time managing your app.

PS: I would like to give a shout out to podman as the rootless version of Docker

Nice
