How To Use Docker Toolbox With MPB

This is a quick start guide to get the mod-plugin-plugin working inside docker, running in Windows or MacOS.

If you're not using Linux please install Docker Toolbox, so you can access docker from within a nice pre-setup VM for it.

Recent experience (July-2023) with the Docker setup on an Apple M1 system can be found at the bottom of this page.

Pre-compiled image

NOTE: The current pre-compiled image can only compile plugins for the Duo. There will be a new pre-compiled version available soon that can build plugins for both Duo and Duo X. At this moment (May 29th, 2019), there are Docker files available that can build plugins for both platforms but these are not pre-compiled (see section "Full build (advanced, long)" below)

After you install and run docker toolbox you should be presented with a command-line interface.
This console is actually running Linux inside a virtual machine, but without you having to do any configuration or setup.

To begin, we download the pre-compiled mod-plugin-builder docker image by running:

$ docker run -ti --name mpb -p 9000:9000 moddevices/mod-plugin-builder

If you wish to have a local folder accessible inside the docker environment, use the '-v' argument with the local and docker mapped folder joined by a semi-colon. Like this:

$ docker run -ti --name mpb -p 9000:9000 -v ~/local-mod-folder:/tmp/local-mod-folder moddevices/mod-plugin-builder

Some notes:

  • The image size is around 1Gb, split across several files.
  • The previous commands will create a new docker environment every time you run them. You only need them once.

After you close the console window, you can resume where you left off by running:

$ docker start -i mpb

Full build (advanced, long)

If you don't want to use a pre-compiled image, you can build mod-plugin-builder yourself. To begin, start docker and navigate to the docker directory:

$ git clone --depth 1
$ cd mod-plugin-builder/docker

After that, you can choose to either create an image for compiling plugins for the DUO, the DUO X, or the DWARF.

All the platforms available are: modduo, modduo-debug, modduo-new, modduo-new-debug, modduo-static, modduox, modduox-debug, modduox-new, modduox-new-debug, modduox-static, moddwarf, moddwarf-debug, moddwarf-new, moddwarf-new-debug, raspberrypi4, x86_64 & x86_64-debug.

To create a Duo image run:

$ docker build -t mpb --build-arg platform=modduo .

Or to create a Duo X image run:

$ docker build -t mpb --build-arg platform=modduox .

Or to create a Dwarf image run:

$ docker build -t mpb --build-arg platform=moddwarf .

NOTE: This will take quite some time...

After it's done, we create a container from mod-plugin-builder by running: (adjust as needed)

$ docker run -ti --name mpb -p 9000:9000 -v C:\Users\<local-mod-folder>:/home/<local-mod-folder> mod-plugin-builder
$ exit

That's it, the command to start the mod-plugin-builder environment is:

$ docker start -i mpb

Docker on an Apple M1 system to build Dwarf plugins

These are the steps to get the MOD plugin builder setup on an Apple M1 system.

This was tested in July-2023 on the following system

Host MacBook Pro 13-inch, M1, 2020 16Gb Memory macOS 13.4.1 (22F82)

Docker Docker Desktop 4.21.1 (114176)  All settings default

Install the MOD plugin builder and create a Docker image using the following commands

cd ~
mkdir dwarf
cd dwarf
git clone
cd mod-plugin-builder/docker
docker build -t mpb --build-arg platform=moddwarf-new .

This results in

Checking in the Docker gui you should be able to see a new image mpb.


cd ..
./ moddwarf-new mpb

will fire up an interactive Docker terminal


In this Docker machine, run

git submodule init
git submodule update

And then in the Docker machine, you can perform builds, such as

./build moddwarf-new abgate
./build moddwarf-new portal-lv2
./build moddwarf-new guitarix
./build moddwarf-new x42-midifilter

Back in the MacOS world, you should be able to see the LV2 files on your drive.
