Jitsi with Docker

Build Your Own Free Video Conference System

This post “Jitsi with Docker” was updated by: Syed Umar Bukhari on September 29, 2021

Jitsi is an open source video conference application that is installed on its server. This video conferencing application provides an SDK for those of you to create video conference applications for mobile. In this post we will build a video conferencing system on Jitsi with Docker. There are many ways to do so; one of the main ways is by using Jitsi as a distributor of IFRAME API JITSI while others deal with LIB-JITSI-MEET API integration into the applications.

One ring to rule them all.

How To Configure Jitsi With Docker?

You can create a custom application suitable for the UI you create and integrate it with Jitsi API. You can find API docs on Jitsi docs. As such, An active support community make Jitsi increasingly popular.

In this post, you will create a video conference app with Jitsi that will run on Docker and learn about the many ways you can do so.

Why Use Docker To Build Jitsi?

We will run the server on AWS, but you can run on other Cloud services.. In this case, use Ubuntu Server 18.04 to run Jitsi on Docker. After that, you need to install Alsa-loopback module.

In addition, you need to install Docker and Docker-Compose. I will assume you have already installed Docker and Docker-Compose on the server before proceeding.

Add Alsa-Loopback Kernel Module On Ubuntu

Alsa-loopback module requires Jibri to make live streaming and recording possible on the Jitsi video conference server. This module is not present on AWS Ubuntu Server by default. Hence, we need to add and enable it manually. To do so, use a generic kernel to make alsa-loopback work on the server.

Upgrade & share files freely!

Get everything you wanted in cloud storage by signing up for a subscription.

With this deal you will get a cloud that works in China, USA Europe and more.

After that, the next few steps are to provide guidance to replace the AWS kernel with a generic AWS kernel. In this case, select Ubuntu on AWS; we recommend doing so in order follow along.

If you have created an EC2 machine with this version, log in to the server and install alsa-utils with this command:

sudo apt install alsa-utils -y

To ensure installation of alsa-loopback, enter this command:

arecord -L

If there is an error when running the command, we must make changes in the AWS kernel to get a GENERIC kernel:

If output : null
Discard all samples (playback) or generate zero samples (capture)

Then, for the next step, search for a generic Linux module with the following command:

apt search

sudo apt search linux-modules-5.4.0 | grep generic

Install Kernel Generic AWS

If you find a generic Linux module– linux-modules-5.4.0-77-generic, use it. After that, install it on the EC2 machine.

Now NEW reduced price of ondemand Cloud Storage and collaboration for team work.

Start and pay as go only! The Cloud Storage you will use. works where even if your team is; in China, America, Eurpe and more and all of them at the same time!

sudo apt install linux-image-5.4.0-77-generic linux-modules-5.4.0-77-generic linux-modules-extra-5.4.0-77-generic -y

Then, next step is to try to find the menu entry in the Linux grub– so that the AWS kernel can be changed to the newly installed GENERIC kernel.

sudo grep -A100 submenu /boot/grub/grub.cfg | grep menuentry

This is it: we’ve got the menu entry for generic kernel modules.

After that, we need to change GRUB_DEFAULT on the EC2 machine to use generic kernel modules in the file /etc/default/grub. We will replace GRUB_DEFAULT with the sed command on linux.

sudo sed -i -e 's/GRUB_DEFAULT=0/GRUB_DEFAULT="gnulinux-advanced-6156ec80-9446-4eb1-95e0-9ae6b7a46187>gnulinux-5.4.0-77-generic-advanced-6156ec80-9446-4eb1-95e0-9ae6b7a46187"/' /etc/default/grub

Since GRUB_DEFAULT has been replaced with generic Linux modules, update Linux grub using the command:

update-grub

sudo update-grub

Therefore, Linux grub has updated successfully.

You landed the Cloud Storage of the future internet. Cloud Storage Services Sesame Disk by NiHao Cloud

Use it NOW and forever!

Support the growth of a Team File sharing system that works for people in China, USA, Europe, APAC and everywhere else.

Now, reboot the server to see if the kernel changed from AWS to the generic kernel. Use this command to reboot the server:

reboot

Reboot Server

After rebooting the server, check if the kernel changed from AWS to GENERIC with this command:

uname -r

Since the kernel has been successfully changed to GENERIC, it’s time to activate the alsa-loopback module.

Activate it with this command:

modprobe snd-aloop

Hence, the alsa-loopback module has been activated. After that, check if the module is active on the server.

arecord -L

Since the alsa-loopback module is already active on the server, move to next step.

For the next step, use Jitsi Docker from the Jitsi Github repository– Jitsi has provided a docker configuration in its repository.

git clone https://github.com/jitsi/docker-jitsi-meet.git

After that, move to the docker-jitsi-meet directory for configuration of some files. You can enable recording and streaming on Jitsi here.

cd docker-jitsi-meet/

Docker-Compose & Jitsi

To configure the env file in Docker Jitsi, it is necessary to pay attention here.

Create a Jitsi Docker using a network with its own domain. Firstly, change the network and its alias from meet.jitsi to your own domain. Let’s edit docker-compose.yml to do so.

We have edited the docker-compose.yml file according to our own network. You can edit it according to your server; first you need to copy env.example to .env with the command “cp env.example .env”.

cp env.example .env

Let’s edit something on the env file; you can read the use cases of each function contained in the env file in the Jitsi docker documentation.

Redirect Env File To HTTPS

# Redirect HTTP traffic to HTTPS
# Necessary for Let's Encrypt, relies on standard HTTPS port (443)
ENABLE_HTTP_REDIRECT=1

Create a high-security password in env file. To generate it, use the command below.

./gen-passwords.sh

In addition, we are required to create the config directory jitsi.

mkdir -p ~/.jitsi-meet-cfg/{web/letsencrypt,transcripts,prosody/config,prosody/prosody-plugins-custom,jicofo,jvb,jigasi,jibri}

Setting The jibri.yml

In this step, configure jibri in the jibri.yml file to replace network with your own domain.

Jibri functions to make recording and livestreaming on Jitsi seamless. Without a further ado, let’s edit the jibri.yml file.

version: '3'

services:
    jibri:
        image: jitsi/jibri:latest
        restart: ${RESTART_POLICY}
        volumes:
            - ${CONFIG}/jibri:/config:Z

The configuration is done. Therefore, you can build container now.

docker-compose -f docker-compose.yml -f jibri.yml up -d

You can use this command to check whether container is already running and up:

docker-compose -f docker-compose.yml -f jibri.yml ps

As visible, Jitsi services are running well in the containers. After that, try to access the video conference page to conference.

To do so, open this URL in a browser according to the domain you configured in the env file.:

https://meet.domainname.tld

Jitsi front page is already successfully installed on server; let’s try to start conference.

To conclude, building Jitsi on Docker is done– you can now start video conferencing with your own server.
