The apt-sources element did not work with debian-minimal, because the later one overwrote the /etc/apt/sources.list file created by the apt-sources element. Two changes were made: o the debian-minimal uses now files inside the /etc/apt/sources.list.d directory. Therefore there is no possibilty for clashes between those two elements any more. o instead of only adding backports, also the updates and the security repository is added by default which gives perfect initial configuration for a stable system. If you want to use local mirrors with other naming schemas or an unstable tree, there is the possibility to fully specify the repositories.

debian-minimal
Create a minimal image based on Debian. We default to unstable but DIB_RELEASE can be set to any series of Debian.
There are two ways to configure apt-sources:
Using the standard way of defining the default, backports, updates and security repositories is the default. In this case you can overwrite the two environment variables to adapt the behavior: `DIB_DISTRIBUTION_MIRROR`: the mirror to use default: http://httpredir.debian.org/debian `DIB_DEBIAN_COMPONENTS`: (default) main a comma separated list of components. For Debian this can be e.g. main,contrib,non-free.
Note that the default Debian series is unstable, and the default mirrors for Debian can be problematic for unstable. Because apt does not handle changing Packages files well across multiple out of sync mirrors, it is recommended that you choose a single mirror of Debian, and pass it in via DIB_DISTRIBUTION_MIRROR.
By default only main component is used. If DIB_DEBIAN_COMPONENTS (comma separated) from the debootstrap element has been set, that list of components will be used instead.
Backports, updates and security are included unless DIB_RELEASE is unstable.
Complete configuration given in the variable DIB_APT_SOURCES_CONF. Each line contains exactly one entry for the sources.list.d directory. The first word must be the logical name (which is used as file name with .list automatically appended), followed by a colon :, followed by the complete repository specification. Example: DIB_APT_SOURCES_CONF= "default:deb http://10.0.0.10/ stretch main contrib mysecurity:deb http://10.0.0.10/ stretch-security main contrib"
If necessary, a custom apt keyring and debootstrap script can be supplied to the debootstrap command via DIB_APT_KEYRING and DIB_DEBIAN_DEBOOTSTRAP_SCRIPT respectively. Both options require the use of absolute rather than relative paths.
Use of this element will also require the tool 'debootstrap' to be available on your system. It should be available on Ubuntu, Debian, and Fedora. It is also recommended that the 'debian-keyring' package be installed.
The DIB_OFFLINE or more specific DIB_DEBIAN_USE_DEBOOTSTRAP_CACHE variables can be set to prefer the use of a pre-cached root filesystem tarball.
The DIB_DEBOOTSTRAP_EXTRA_ARGS environment variable may be used to pass extra arguments to the debootstrap command used to create the base filesystem image. If --keyring is is used in DIB_DEBOOTSTRAP_EXTRA_ARGS, it will override DIB_APT_KEYRING if that is used as well.
Note on ARM systems
Because there is not a one-to-one mapping of ARCH to a kernel package, if you are building an image for ARM on debian, you need to specify which kernel you want in the environment variable DIB_ARM_KERNEL. For instance, if you want the linux-image-mx5 package installed, set DIB_ARM_KERNEL to mx5.
