Prerequisites

This image assumes that you are using a reverse proxy such as jwilder/nginx-proxy and optionally the Let's Encrypt Proxy Companion @ https://github.com/JrCs/docker-letsencrypt-nginx-proxy-companion in order to serve your pages. However, it will run just fine on it's own if you map appropriate ports.

You will also need an external MySQL/MariaDB Container

Installation

Automated builds of the image are available on Docker Hub and is the recommended method of installation.

docker pull tiredofit/freepbx

Quick Start

• The quickest way to get started is using docker-compose. See the examples folder for a working docker-compose.yml that can be modified for development or production use.

• Set various environment variables to understand the capabilities of this image.

• Map persistent storage for access to configuration and data files for backup.

• Make networking ports available for public access if necessary

The first boot can take from 3 minutes - 30 minutes depending on your internet connection as there is a considerable amount of downloading to do!

Login to the web server and enter in your admin username, admin password, and email address and start configuring the system!

Configuration

Data-Volumes

The container supports data persistence and during Dockerfile Build creates symbolic links for /var/lib/asterisk, /var/spool/asterisk, /home/asterisk, and /etc/asterisk. Upon startup configuration files are copied and generated to support portability.

The following directories are used for configuration and can be mapped for persistent storage.

Directory	Description
/certs	Drop your Certificates here for TLS w/PJSIP / UCP / HTTPd/ FOP
/www/freepbx	FreePBX web files
/var/log/	Apache, Asterisk and FreePBX Log Files
/data	Data Persistence for Asterisk and Freepbx and FOP
/assets/custom	OPTIONAL - If you would like to overwrite some files in the container, put them here following the same folder structure for anything underneath the /var/www/html directory

Environment Variables

Along with the Environment Variables from the Base image, below is the complete list of available options that can be used to customize your installation.

DB_PORT	MySQL Port - Default 3306
DB_NAME	MySQL Database name e.g. asterisk
DB_USER	MySQL Username for above Database e.g. asterisk
DB_PASS	MySQL Password for above Database e.g. password
ENABLE_FAIL2BAN	Enable Fail2ban to block the bad guys - Default TRUE
ENABLE_FOP	Enable Flash Operator Panel - Default TRUE
ENABLE_SSL	Enable HTTPd to serve SSL requests - Default FALSE
HTTP_PORT	HTTP Listening Port - Default 80
HTTPS_PORT	HTTPS Listening Port - Default 443
FOP_DIRECTORY	What folder to access FOP - Default /fop
RTP_START	What port to start RTP Transmissions - Default 18000
RTP_FINISH	What port to start RTP Transmissions - Default 20000
UCP_FIRST	Load UCP as web frontpage TRUE/FALSE - Default TRUE
TLS_CERT	TLS Certificate to drop in /certs for HTTPS if no reverse proxy
TLS_KEY	TLS Key to drop in /certs for HTTPS if no reverse proxy
WEBROOT	If you wish to install to a subfolder use this. Example: /var/www/html/pbx Default '/var/www/html'

ADMIN_DIRECTORY and FOP_DIRECTORY may not work correctly if WEBROOT is changed or UCP_FIRST=FALSE

Networking

The following ports are exposed.

Port	Description
80	HTTP
443	HTTPS
4445	FOP
4569	IAX
5060	PJSIP
5160	SIP

8008	UCP
8009	UCP SSL
18000-20000/udp	RTP Ports

Maintenance

• There seems to be a problem with the CDR Module when updating where it refuses to update when using an external DB Server. If that happens, simply enter the container (as shown below) and execute upgrade-cdr, which will download the latest CDR module, apply a tweak, install, and reload the system for you.

Known Bugs

• When installing Parking Lot or Feature Codes you sometimes get SQLSTATE[22001]: String data, right truncated: 1406 Data too long for column 'helptext' at row 1. To resolve login to your SQL server and issue this statement: alter table featurecodes modify column helptext varchar(500);
• If you find yourself needing to update the framework or core modules and experience issues, enter the container and run upgrade-core which will truncate the column and auto upgrade the core and framework modules.

Shell Access

For debugging and maintenance purposes you may want access the containers shell.

docker exec -it (whatever your container name is e.g. freepbx) bash
