Multiarch FreePBX container(tested with armv7 and amd64).
This is an experimental image, probably not safe for production.
- Asterisk 16
- FreePBX 15
- chan_dongle
See docker-compose.yml.
To use chan_dongle enable the devices: section of docker-compose.yml also check the actual device paths on your machine(I used an udev trick to have them always have the same name, see config/92-dongle.rules)
There are no all-in one tutorials but you can read about multiarch builds https://docs.docker.com/buildx/working-with-buildx/.
You will also need to enable binfmt and have qemu on your system which is the harder part.
If you are on docker 19.03 or later you can use the built in buildx or install the latest version from https://github.com/docker/buildx/.
A good tutorial on enabling binfmt and setting things up: https://community.arm.com/developer/tools-software/tools/b/tools-software-ides-blog/posts/getting-started-with-docker-for-arm-on-linux.
For QEMU use your distro's package or, if you are feeling adventurous(like I did), build it from source and use checkinstall so that it doesn't blow up your system: https://www.qemu.org/download/.
I used qemu 5.0.0 for this build.
If you want to build this yourself then first run build-base.sh to build the base image. Check the script for the --platform flags you need. By default this will output arm/v7 and amd64.
The FreePBX install part does not work on Qemu currently(asterisk crashes) so I manually built the last part on an armv7 machine and then used docker manifest to combine it with the amd64 version.YMMV. Tutorial on manifest https://medium.com/@mauridb/docker-multi-architecture-images-365a44c26be6
