Base element for creating minimal debian-based images.
This element is incomplete by itself, you’ll want to use elements like debian-minimal or ubuntu-minimal to get an actual base image.
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://deb.debian.org/debian)
main) a comma separated list of components. For Debian this can be e.g.
By default only the
maincomponent is used. If
DIB_DEBIAN_COMPONENTS(comma separated) from the
debootstrapelement has been set, that list of components will be used instead.
Backports, updates and security are included unless
Complete configuration given in the variable
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
.listautomatically appended), followed by a colon
:, followed by the complete repository specification.
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_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.
DIB_OFFLINE or more specific
variables can be set to prefer the use of a pre-cached root filesystem
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 used in
it will override
DIB_APT_KEYRING if that is used as well.
For further information about
please consult “README.rst” of the debootstrap element.
/etc/network/interfaces.d/eth[0|1] files will be
created and enabled with DHCP networking. If you do not wish this to
be done, set
0. If you
need different interface names than
DIB_NETWORK_INTERFACE_NAMES to a space separated list of network
interface names like:
export DIB_NETWORK_INTERFACE_NAMES="ens3 ens4"
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
linux-image-mx5 package installed, set
