This is a containerized standalone songbook server for OpenKJ. The fonts and CSS files it pulled from Google servers have been included, so the server can run 100% off-grid.

Get the server up and running:

docker run -d --name openkj-songbook -p 80:8000 -v openkj-db:/db -e VENUE="City Karaoke" --rm git.alfter.us/salfter/openkj-request-docker

docker compose up -d

(customize VENUE to suit)

Start up OpenKJ
Select Tools -> Settings and go to the Network tab
Set Server URL to http://localhost/api.php (assuming you're running this alongside OpenKJ)
Click Test to verify that the server is running, then click Close
Select Karaoke -> Incoming Requests
Make sure Accept Requests is checked
Make sure Automatically show this dialog on new requests is checked
Click Update Remote DB

For off-grid use, linux-wifi-hotspot works pretty well...set up an open access point and scribble the IP address on a whiteboard so people can use their phones to search songs and make requests, or point a 2nd computer at it for the purpose.
