version: '3.3'
services:
  jvbz:
    build: .
    volumes:
      - "./src:/jvb:rw"
      - "./.m2:/root/.m2:rw"
    working_dir: /jvb
    ports:
      - "8086:1999"

Jitsi Videobridge is an XMPP server component that allows for multiuser video communication. Unlike the expensive dedicated hardware videobridges, Jitsi Videobridge does not mix the video channels into a composite video stream, but only relays the received video channels to all call participants. Therefore, while it does need to run on a server with good network bandwidth, CPU horsepower is not that critical for performance.

Can someone please help me with this.
