I find it a bit difficult to navigate the open source alternatives. Some needs a lot of work for downloading / transforming the data, and others are split into multiple software components.

Are there any plug-and-play options where I can just download a docker image and get a simple backend that can be used for frontend maps and an address auto-complete? Alternatively a separate docker image for the tile server (if that is the right terminology). Preferably with an option to only include data for certain geographical areas to save space.
