Asterisk 17 PBX

docker login docker build -t domonapapp/asterisk:20 . docker system prune docker push domonapapp/asterisk:20

Since COPY copies files including their metadata, you can also simply change the permissions of the file in the host machine (the one building the Docker image): $ chmod +x entrypoint.sh

chown asterisk /etc To change all the directories to 755 (drwxr-xr-x):

find /asterisk -type d -exec chmod 755 {} ; To change all the files to 644 (-rw-r--r--):

find /asterisk -type f -exec chmod 644 {} ;

cdchown -R asterisk:asterisk asterisk

Uses debian:buster-slim because uuid-dev is not available in Alpine.

Builds Asterisk 17 from git master.

Multi-stage Dockerfile uses build-essential and git to clone from the git repository https://github.com/asterisk/asterisk.git

First stage installs the prerequisites and builds Asterisk from source. Second stage copies the compiled assets from the first, sets up the asterisk user and sets permissions.

Includes the Festival Text-To-Speach Server and LDAP support.

Now with opus codec from https://downloads.digium.com/pub/telephony/codec_opus/ and with res_rtsp as it was missing from earlier builds because of a non-included librtsp2-dev.

/etc/asterisk is populated with the config samples from make samples. Mount your own folder to overwrite the samples.

Build

$ docker build -t domonapapp/asterisk:20 .

Usage

$ docker run -v ${PWD}/etc/asterisk/:/etc/asterisk:rw ${PWD}/log/:/var/log/asterisk:rw domonapapp/asterisk bash

docker-compose.yml

Note: Use network_mode: "host" as the RTP service requires a large port range and it takes a long time to setup thousands of iptable rules if it uses a docker network.

LDAP Support

You will need to import the asterisk.ldif schema into your LDAP configuration. This is an olc format file, if you need the older schema format you'll find it in the link below.

Full details are here: Asterisk LDAP Integration

ODBC and PostgreSQL Support

Now build with ODBC and the postgresql-client to enble the use of real-time databases.

Festival TTS

Festival is a default install listening on TCP port 1314 - but does not need to be exposed.

Supervisor

Supervisor is used to start the two programs (festival and asterisk) within the container. The supervisor configuration is included as asterisk.conf

Minor change to the asterisk startup to put it into non-colour console.
