Nowadays, in the time of Predictable Network Interface Names, the network interface names 'ethX' are not used that often any more. Depending on the virtualization layer and the guest OS names like 'ens3', 'enp1s0' or 'enp0s31f6' are used. This patch enables the user to set DIB_NETWORK_INTERFACE_NAMES to a list of network interfaces which are brought up using DHCP during (first) boot.

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:
|
|
|
|
1. 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>`__)
|
|
* ``DIB_DEBIAN_COMPONENTS``: (default: ``main``) a comma
|
|
separated list of components. For Debian this can be
|
|
e.g. ``main,contrib,non-free``.
|
|
|
|
By default only the ``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``.
|
|
|
|
2. 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.
|
|
|
|
.. code-block:: bash
|
|
|
|
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 used in ``DIB_DEBOOTSTRAP_EXTRA_ARGS``,
|
|
it will override ``DIB_APT_KEYRING`` if that is used as well.
|
|
|
|
For further information about ``DIB_DEBIAN_DEBOOTSTRAP_SCRIPT`` ,
|
|
``DIB_DEBIAN_USE_DEBOOTSTRAP_CACHE`` and ``DIB_DEBOOTSTRAP_EXTRA_ARGS``
|
|
please consult "README.rst" of the debootstrap element.

----------
|
|
|
|
By default ``/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 ``DIB_APT_MINIMAL_CREATE_INTERFACES`` to ``0``. If you
|
|
need different interface names than ``eth[0|1]`` set
|
|
``DIB_NETWORK_INTERFACE_NAMES`` to a space separated list of network
|
|
interface names like:
|
|
|
|
.. code-block:: bash
|
|
|
|
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
|
|
the ``linux-image-mx5`` package installed, set ``DIB_ARM_KERNEL`` to ``mx5``.
