Asterisk in Docker

Read the Docker page if you don't know what Docker is.

Notes on building a current executable, the old way: Building Asterisk

Building a docker container

I used with the github respoke/asterisk image as my starting point.

git clone [email protected]:respoke/asterisk-docker.git

Then I broke respoke's image out into two parts, so that it would build faster.

Currently I work logged into Bellman.

I have a Debian Stretch container wildsong/build that has all the tools in it, when the container builds it downloads sources and configures and compiles them.

cd source/docker/docker-build

Once the 'build' container is working, check in changes to github and a new copy will build at hub.docker.com.

Configuration

Put environment settings into Dockerfile and add j2 config files that I created for Fogg.

The configuration is entirely file based because my home phone system is relatively static.

The docker-asterisk container configures Asterisk based on templates in etc_asterisk.

cd source/docker/docker-asterisk
edit Dockerfile to adjust environment
cd etc_asterisk
edit files
cd ..
docker rm -f asterisk
docker build -t asterisk .

Launch server

Using the --net=host option is not a best practice because it exposes every port running on the docker machine. It means it looks like Asterisk is just running on Bellman, not inside a container.

docker run -d --net=host --name=asterisk asterisk

I don't think I need any -p port mappings or --expose if I use --net=host, and though it's not "best practices" it will make Asterisk networking problems go away pretty much.

Console

You can connect to the Asterisk console directly with this command

docker exec -it asterisk asterisk -r

Or you can connect the usual way via a bash shell

docker exec -it asterisk bash

tcpdump -n not port 22 and not arp and not host 192.168.123.159

Connected phones

I don't know how to see what phones are registered with pjsip!??

I started a separate page for it, PJSIP.
