Jitsi Videobridge Integrated with Node Exporter

This is a project rolled back to stable-4548 version for compatibility with podium jisti patch file. Also, this includes the modified jvb container with node exporter for monitoring the system informations, not its colibri stats. The original README is README-orig.md.

This project is already patched. Don't patch this file.

The docker images built in this project are for k8s/OCP, not docker environment.

I added rootfs/etc/services.d/run script file to s6-overlay tree to run node_exporter binary.

#!/usr/bin/with-contenv bash

if [[ -z "$EXPORTER_TCP_PORT" ]]; then
  EXPORTER_TCP_PORT=9100
fi

exec /bin/bash -c '/node_exporter --web.listen-address=":$EXPORTER_TCP_PORT"'

You can change the port number by setting the EXPORTER_TCP_PORT environment variable.

Workflow

Build

$ git clone https://github.com/kkh913/docker-jitsi-meet.git
$ cd docker-jitsi-meet
$ chmod +x base/rootfs/*.sh
$ FORCE_REBUILD=1 make
$ docker images

(Optional) Push

Your quay.io ID is needed for the followings.

docker login quay.io 
docker tag jitsi/jvb:latest quay.io/<your id>/<your project name>:<version> 
docker push quay.io/<your id>/<your project name>:<version>

Pull test

For user permissions, because this image works on non-root mode.

# if your system don't have uid 1001, 
useradd -u 1001 -r -s /bin/false user
cp env.example .env 
./gen-passwords.sh 
mkdir -p ~/.jitsi-meet-cfg/{prosody/config,prosody/prosody-plugins-custom,jvb}
chown -R 1001:0 ~/.jitsi-meet-cfg

Add EXPORTER_TCP_PORT=9888 in .env

EXPORTER_TCP_PORT=9888

Edit docker-compose.yaml

...
# Video bridge
jvb:
  image: quay.io/<your id>/<your project name>:<version>
  restart: ${RESTART_POLICY}
  ports:
    - '${JVB_PORT}:${JVB_PORT}/udp'
    - '${JVB_TCP_MAPPED_PORT}:${JVB_TCP_PORT}'
    - '${EXPORTER_TCP_PORT}:${EXPORTER_TCP_PORT}/tcp'
  volumes:
    ...
  environment:
      - EXPORTER_TCP_PORT
      ...

I strongly recommend you comment out all services except prosody and jvb for test.

docker-compose up -d 
curl localhost:9888/metrics
