Jitsi Meet on Docker

Jitsi is a set of Open Source projects that allows you to easily build and deploy secure videoconferencing solutions.

Jitsi Meet is a fully encrypted, 100% Open Source videoconferencing solution that you can use all day, every day, for free — with no account needed.

This repository contains the necessary tools to run a Jitsi Meet stack on Docker using Docker Compose.

NOTE: This setup is experimental.

Quick start

In order to quickly run Jitsi Meet on a machine running Docker and Docker Compose, follow these steps:

• Create a .env file by copying and adjusting env.example.
• Run docker-compose up -d.
• Access the web UI at https://localhost:8443 (or a different port, in case you edited the compose file yourself.

Architecture

A Jitsi Meet installation can be broken down into the following components:

• A web interface
• An XMPP server
• A conference focus component
• A video router (could be more than one)

This project separates each of the components above into interlinked containers. To this end, several container images are provided.

TODO: image.

Images

• base: Debian stable base image with the S6 Overlay for process control and the Jitsi repositories enabled. All other images are based off this one.
• base-java: Same as the above, plus Java (OpenJDK).
• web: Jitsi Meet web UI, served with nginx.
• prosody: Prosody, the XMPP server.
• jicofo: Jicofo, the XMPP focus component.
• jvb: Jitsi Videobridge, the video router.

Note: see the README on each image for a description of all possible configuration options. Not all of them need to be set for a compose setup, please check docker-compose.yml and env.example for the required ones.

Design considerations

Jitsi Meet uses XMPP for signalling, thus the need for the XMPP server. The setup provided by these containers does not expose the XMPP server to the outside world. Instead, it's kept completely sealed, and routing of XMPP traffic only happens on a user defined network.

The XMPP server can be exposed to the outside world, but that's out of the scope of this project.

Configuration

The following variables can be set in the .env file to customize the installation:

• CONFIG=/opt/jitsi-meet-cfg - Volume where the configuration of all the containers will be stored.
• TZ=Europe/Amsterdam - System time zone.
• XMPP_DOMAIN=meet.jitsi - Domain for the XMPP server. The default works fine, since the server is only accessible via the internal container network.
• JVB_COMPONENT_SECRET=s3cr3t - Password used by the Jitsi Videobridge when connecting to the XMPP server as a component.
• JVB_STUN_SERVERS=stun.l.google.com:19302,stun1.l.google.com:19302,stun2.l.google.com:19302 - STUN servers used to harvest the public IP address.
• JICOFO_COMPONENT_SECRET=s3cr37 - Password used by Jicodo when connecting to the XMPP server as a component.
• JICOFO_AUTH_USER=focus - Username used by Jocofo when connecting to the XMPP server as a client.
• JICOFO_AUTH_PASSWORD=passw0rd - Password used by Jicofo when connecting to the XMPP server as a client.

Limitations

Currently a single Jitsi Videobridge is supported, and it has to run in host mode, that is, directly connected to the host's network.

Multiple container replicas are not supported.

Docker Swarm mode is not yet supported.
