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 http://localhost:8000 for HTTP, or a different port, in case you edited the compose file).

If you want to use jigasi too, first configure your env file with SIP credentials and then run Docker Compose as follows: docker-compose -f docker-compose.yml -f jigasi.yml up -d

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)
• A SIP gateway for audio calls

The diagram shows a typical deployment in a host running Docker. This project separates each of the components above into interlinked containers. To this end, several container images are provided.

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.
• jigasi: Jigasi, the SIP (audio only) gateway.

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 configuration is performed via environment variables contained in a .env file. You can copy the provided env.example file as a reference.

IMPORTANT: At the moment, configuration is not regenerated on every container boot, so if you make any changes to your .env file, make sure you remove the configuration directory before starting your containers again.

Variable	Description	Example
CONFIG	Directory where all configuration will be stored	/opt/jitsi-meet-cfg
TZ	System Time Zone	Europe/Amsterdam
HTTP_PORT	Exposed port for HTTP traffic	8000
HTTPS_PORT	Exposed port for HTTPS traffic	8443
DOCKER_HOST_ADDRESS	IP address of the Docker host, needed for LAN environments	192.168.1.1

NOTE: The mobile apps won't work with self-signed certificates (the default) see below for instructions on how to obtain a proper certificate with Let's Encrypt.

Let's Encrypt configuration

If you plan on exposing this container setup to the outside traffic directly and want a proper TLS certificate, you are in luck because Let's Encrypt support is built right in. Here are the required options:

Variable	Description	Example
ENABLE_LETSENCRYPT	Enable Let's Encrypt certificate generation	1
LETSENCRYPT_DOMAIN	Domain for which to generate the certificate	meet.example.com
LETSENCRYPT_EMAIL	E-Mail for receiving important account notifications (mandatory)	alice@atlanta.net

In addition, you will need to set HTTP_PORT to 80 and HTTPS_PORT to 443.

SIP gateway configuration

If you want to enable the SIP gateway, these options are required:

Variable	Description	Example
JIGASI_SIP_URI	SIP URI for incoming / outgoing calls	test@sip2sip.info
JIGASI_SIP_PASSWORD	Password for the specified SIP account	passw0rd
JIGASI_SIP_SERVER	SIP server (use the SIP account domain if in doubt)	sip2sip.info
JIGASI_SIP_PORT	SIP server port	5060
JIGASI_SIP_TRANSPORT	SIP transport	UDP

Authentication

Authentication can be controlled with the environment variables below. If guest access is enabled, unauthenticated users will need to wait until a user authenticates before they can join a room. If guest access is not enabled, every user will need to authenticate before they can join.

Variable	Description	Example
ENABLE_AUTH	Enable authentication	1
ENABLE_GUESTS	Enable guest access	1

Users must be created with the prosodyctl utility in the prosody container. In order to do that, first execute a shell in the corresponding container:

docker-compose exec prosody /bin/bash

Once in the container, run the following command to create a user:

prosodyctl --config /config/prosody.cfg.lua register user meet.jitsi password

Advanced configuration

These configuration options are already set and generally don't need to be changed.

Variable	Description	Default value
XMPP_DOMAIN	Internal XMPP domain	meet.jitsi
XMPP_AUTH_DOMAIN	Internal XMPP domain for authenticated services	auth.meet.jitsi
XMPP_MUC_DOMAIN	XMPP domain for the MUC	muc.meet.jitsi
XMPP_INTERNAL_MUC_DOMAIN	XMPP domain for the internal MUC	internal-muc.meet.jitsi
XMPP_GUEST_DOMAIN	XMPP domain for unauthenticated users	guest.meet.jitsi
XMPP_MODULES	Custom Prosody modules for XMPP_DOMAIN (comma separated)	mod_info,mod_alert
XMPP_MUC_MODULES	Custom Prosody modules for MUC component (comma separated)	mod_info,mod_alert
XMPP_INTERNAL_MUC_MODULES	Custom Prosody modules for internal MUC component (comma separated)	mod_info,mod_alert
JICOFO_COMPONENT_SECRET	XMPP component password for Jicofo	s3cr37
JICOFO_AUTH_USER	XMPP user for Jicofo client connections	focus
JICOFO_AUTH_PASSWORD	XMPP password for Jicofo client connections	passw0rd
JVB_AUTH_USER	XMPP user for JVB MUC client connections	jvb
JVB_AUTH_PASSWORD	XMPP password for JVB MUC client connections	passw0rd
JVB_STUN_SERVERS	STUN servers used to discover the server's public IP	stun.l.google.com:19302, stun1.l.google.com:19302, stun2.l.google.com:19302
JVB_PORT	UDP port for media used by Jitsi Videobridge	10000
JVB_TCP_HARVESTER_DISABLED	Disable the additional harvester which allows video over TCP (rather than just UDP)	true
JVB_TCP_PORT	TCP port for media used by Jitsi Videobridge when the TCP Harvester is enabled	4443
JVB_BREWERY_MUC	MUC name for the JVB pool	jvbbrewery
JVB_ENABLE_APIS	Comma separated list of JVB APIs to enable	none
JIGASI_XMPP_USER	XMPP user for Jigasi MUC client connections	jigasi
JIGASI_XMPP_PASSWORD	XMPP password for Jigasi MUC client connections	passw0rd
JIGASI_BREWERY_MUC	MUC name for the Jigasi pool	jigasibrewery
JIGASI_PORT_MIN	Minimum port for media used by Jigasi	20000
JIGASI_PORT_MAX	Maximum port for media used by Jigasi	20050
DISABLE_HTTPS	Disable HTTPS, this can be useful if TLS connections are going to be handled outside of this setup	1
ENABLE_HTTP_REDIRECT	Redirects HTTP traffic to HTTPS	1

Running on a LAN environment

If running in a LAN environment (as well as on the public Internet, via NAT) is a requirement, the DOCKER_HOST_ADDRESS should be set. This way, the Videobridge will advertise the IP address of the host running Docker instead of the internal IP address that Docker assigned it, thus making ICE succeed.

The public IP address is discovered via STUN. STUN servers can be specified with the JVB_STUN_SERVERS option.

TODO

• Support container replicas (where applicable).
• Docker Swarm mode.
• More services:
  • Jibri.
  • TURN server.
