Build Asterisk source into RPM packages as basis of a Docker container image.

NOTE: This is a work in progress. More updates to follow as this stabilizes.

Building the RPM builder image

There are two Dockerfiles; one for building the container image that will result in RPMS, and one that will build the actual Asterisk container image.

To build the RPM builder:

docker build -t username/astbuilder:latest -f Dockerfile.asterisk-builder .

Build RPMS

You can now use your new Docker container image to build yourself a fancy set of Asterisk RPMs. This is done using fedpkg to build RPM dependencies (speex, speexdsp, dahdi-tools, libpri, libresample, libss7) and then builds Asterisk 13.

Then you run the following to build out the RPMs:

docker run -ti username/astbuilder

After a while (probably a good 10-15 minutes), you should have resulting RPMs that have been built from the Fedora SPEC files.

NOTE: At some point this will be enhanced somehow to allow resulting Asterisk RPMs to be

Accessing RPMs when building Asterisk container image

NOTE: Hopefully this process will change soon and be a little more automated.

We need to copy out our resulting RPMs so that we can install them into our new Asterisk container image we're about to build. Copying the RPMs out of the container can be done with the following docker commands.

Get the image name

docker ps -a

CONTAINER ID        IMAGE               COMMAND                  CREATED             STATUS                      PORTS               NAMES
5baee40b62c2        madsen/astbuilder   "/bin/sh -c ./buildit"   34 minutes ago      Exited (0) 22 minutes ago                       hungry_torvalds

Copy the files out

docker cp hungry_torvalds:/buildrpms/localrpms/ ./rpms/

You should now have many RPMs sitting in your local rpms/ directory.

Building Asterisk container image

Last step is to build out your container image. The Dockerfile for our new image will be installing the RPMs that you built within the builder image. These RPMs will get added to the container image on build by mounting the files from the host into the build via volume.

docker build -t username/asterisk:13.3.2-1 -f Dockerfile.asterisk .
