Run multiple Asterisk instances on the same box. Run regression tests. Simulate clusters. All on Docker.
This project was born as a simple way to do regression testing on WombatDialer, our nice intelligent dialer that just works with any existing Asterisk PBX, and QueueMetrics, our well-known call-center reporting and monitoring suite. But you can use it to test any AMI/ARI application or piece of dialplan.
So you want to run an Asterisk 13 box and expose AMI on port 12345 of your host?
docker run -p 12345:5038 -P -d lenz/asterisk-load-test-13
And you also want to run an Asterisk 1.8 and expose its AMI on port 12346 of the same box?
docker run -p 12346:5038 -P -d lenz/asterisk-load-test-1.8
This makes it very easy to develop AMI / ARI applications.
Want to run WombatDialer to put some load on those images?
docker run -p 8080:8080 -P -d loway/wombatdialer
And connect to it over HTTP http://server.ip:8080/wombat (login as 'demoadmin' password 'demo'). See https://registry.hub.docker.com/u/loway/wombatdialer/

Extension | What |
---|---|
any @ wdtrunk | Waits between 1 and 5 seconds, then answers 70% of the calls with a length of 10-30 secs. All other calls are BUSY. |
any @ wdtkallanswered | Waits 1 second, andswers and waits 10 seconds before hanging up. |
100 @ wdep | Answers and plays MOH indefinitely. |
20XXX @ wdep | Fake agent. Answers in 1 to 5 seconds and keeps the call up for 100 to 200 seconds. |
30XXX @ wdep | Fake short agent. Answers in 1 second and keeps the call up for 15 seconds. |
301 @ wdep | Routes calls to queue q1 |
302 @ wdep | Routes calls to queue q2 |
100 @ wdivr | Plays back "" and at the end of the file sets the WombatDialer's EXTSTATUS to 123. |
As these are standard Whaleware images, you can use them as base images and then inject your own dialplan / configuration files. Whaleware offers a complete lifecycle management you can hook into, though in most cases you will simply add a few more files.
Copy the appropriate Dockerfile into build/
docker build -tag=ast11 .
docker run -p 2000:5038 a11
will add port 5038 (AMI) as port 2000
Running
docker run -p 2010:5038 -P -d lenz/asterisk-load-test-13
Note where your AMI port is:
[root@localhost ~]# telnet 127.0.0.1 2004
Trying 127.0.0.1...
Connected to 127.0.0.1.

Action: logoff
Response: Goodbye
Message: Thanks for all the fish.
Connection closed by foreign host.
Note where your ARI port is.
curl -u ari4java:yothere -X GET "http://localhost:49156/ari/asterisk/info"
Running a shell:
docker exec -it 52af95db1e52 /bin/bash
docker exec -it 52af95db1e52 /usr/sbin/asterisk -r
or just to run a command:
docker exec 52af95db1e52 /usr/sbin/asterisk -rx reload
Please note that at the moment you cannot run too many channels on a Docker instance, because you cannot set ulimit within a Docker image:
This should be fixed in Docker 1.6 - see https://blog.docker.com/2015/04/docker-release-1-6/
So it should be possible to run:
docker run -p 12345:5038 -P -d --default-ulimit nofile=1000:1000 lenz/asterisk-load-test-13
To set the soft and hard max files to 1000. But I have not tested this yet.
