Since http://httpredir.debian.org is unreliable is selecting a mirror to use, we'll now default to http://ftp.us.debian.org/debian. In fact, in openstack-infra we have been overriding httpredir.debian.org for a while, now make this default in diskimage-builder.

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:
|
|
|
|
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://ftp.us.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 it is not recommended to use http://httpredir.debian.org/ for
|
|
`DIB_DISTRIBUTION_MIRROR` due to how unreliable it is. Be sure to
|
|
select a mirror from the official mirror list:
|
|
|
|
https://www.debian.org/mirror/list
|
|
|
|
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`.
|
|
|
|
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.
|
|
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.
|
|
|
|
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.

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`.
