Build in Docker

To make sure that the host system configuration does not interfere with a simple-CDD build, it's useful to build the image inside a docker container. The following lists instructions to setup such a docker image.

Install and configure docker

First, install and configure docker. Please refer to the script setup_docker.sh on how to do this.

Dockerfile

First create a file called Dockerfile with the contents below. Replace <dist> with the Debian version for which you'd like to build your image, e.g. buster, bullseye or bookworm:

FROM debian:<dist>-slim

RUN apt-get update
RUN apt-get -y install --install-recommends simple-cdd xorriso gpg distro-info-data

RUN sed -i 's/if a == "amd64" and "i386" not in self.env.get("ARCHES"):/if False and a == "amd64" and "i386" not in self.env.get("ARCHES"):/' /usr/share/simple-cdd/build-simple-cdd  
#(1)!

RUN useradd -ms /bin/bash user
USER user
WORKDIR /home/user
  1. When building with Simple-CDD v0.6.9, this hack is necessary to disable the enforcement of installing the i386 installer for amd64 builds. This will fail, because this installer was removed from Trixie.

Build docker image

Build the docker image with the following command (again replace <dist>): 

docker build -t <dist>-simple-cdd .

Call simple-cdd inside docker

For repeated build attempts, it makes sense to wrap the dockerized simple-CDD call into a bash script e.g. called docker_simple_cdd (don't forget to replace <dist> and make the script executable using chmod +x docker_simple_cdd): 

#!/bin/bash
ARGS="$@"
docker run -it --mount "type=bind,source=$(pwd),destination=/home/user" <dist>-simple-cdd /bin/sh -c "simple-cdd $ARGS"

Now you can build an image e.g. from the desktop profile by issuing:

./docker_simple_cdd --profiles desktop
