jitsi

Module for installing Jitsi Server (via docker-compose) and Client (as AppImage)

Description

This module acts as a wrapper around a wrapper. On the server, it clones a stable version of the docker-composer file, performs some minor modifications and starts the server. By default it expects you to install a reverse proxy which exposes jitsi to the internet.

On the client it downloads a stable version of the AppImage from GitHub and saves it on /usr/local/bin.

Client and server classes are completely unrelated but, of course, deal with connected subjects.

Usage

Client

The class for the client does not need any further parameters but can work with the defaults. Just assign it to your node and it will download the AppImage from the GitHub Releases.

include jitsi::client

You can also specify the version you want to download. In that case make sure you also specify the corresponding checksum and checksum type.

class { 'jitsi::client':
  version       => 'v2.8.5',
  checksum      => 'a5a97217d72c7711efe9a1dffa51f75f93105cdfdf951e7dcc90724b89feb41b964cc664d7f9b6df5662ba6841a40e6b6613e07d6c9f08510ef32fadb1bdb242',
  checksum_type => 'sha512',

Containerized Server

To install the containerized version of the Jitsi server part no more input parameters are required. Secrets are determined automatically.

class { 'jitsi::containerized_server': }

You can set all parameters using hiera:

classes:
  - jitsi::containerized_server

There are several files governing the behaviour of your jitsi server. Most of the settings are passed to the containers as environment variable using the file .env Settings concerning the web frontend are changed in ${CONFIG_DIR}/web/config.js. Both are rendered from templates.

You can add environment variables (see Self-Hosting Guide - Docker) via custom_variables parameter, if they aren't represented as a parameter itself:

jitsi::containerized_server::custom_variables:
  DISABLE_AUDIO_LEVELS: 0
  ENABLE_END_CONFERENCE: 0

Changing ports

You can, for instance, change the ports the containers expose. By default they are running on 30799 for HTTP and 30800 for HTTPS. The HTTP port is relevant if you place your jitsi behind a reverse proxy. In that case it is also recommended to set your public url:

jitsi::containerized_server::http_port: 30032
jitsi::containerized_server::https_port: 30033
jitsi::containerized_server::public_url: "https://your.jitsi.domain

Note that so far, no testing of the Let's Encrypt Integration have been done.

Changing web frontend

On the server side we set several values:

• default video resolution is set to 720p
• layer suspension is enabled
• you have several options to control audio processing.

Jitsi by default does some audio processing. You can turn it off completely by passing

jitsi::containerized_server::disable_all_audio_processing: true

Note the inverse structure: The parameters are meant to disable features, so setting the parameters to false activates the function. By default this setup disables auto gain controll and high pass filters while enabling echo cancellation and noise suppression

jitsi::containerized_server::disable_echo_cancellation: false
jitsi::containerized_server::disable_noise_supression: false
jitsi::containerized_server::disable_auto_gain_control: true
jitsi::containerized_server::disable_high_pass_filter: true

Starting additional containers

You can add additional container to compose process (like Jigasi, Jibri and Etherpad) using these parameters:

jitsi::containerized_server::compose_jigasi: false
jitsi::containerized_server::compose_jibri: false
jitsi::containerized_server::compose_etherpad: false

Notes

This is an experiment on how to handle standalone containerized applications.
