The computation of image name has been moved to a separate function. This allowed simplification in how work dir for isos is computed, but the result is not changed. The live image phase has some special casing for names of RPM wrapped ISOs. This is moved to the actual phase. Since this is (and has been) undocumented, there should not be many users of this special case. The documentation is updated to describe how image names and volume ids are determined and how the process can be customized. Signed-off-by: Lubomír Sedlář <lsedlar@redhat.com>

Base Product
|
|
============
|
|
Base product options are **optional** and we need
|
|
to them only if we're composing a layered product
|
|
built on another (base) product.
|
|
|
|
|

General Settings
|
|
================
|
|
|
|
Options
|
|
-------
|
|
|
|
**comps_file** [mandatory]
|
|
(*scm_dict*, *str* or None) -- reference to comps XML file with installation groups
|
|
|
|
**variants_file** [mandatory]
|
|
(*scm_dict* or *str*) -- reference to variants XML file that defines release variants and architectures
|
|
|
|
Example
|
|
-------
|
|
::
|
|
|
|
comps_file = {
|
|
"scm": "git",
|
|
"repo": "https://git.fedorahosted.org/git/comps.git",
|

|
|
}
|
|
|
|
|
|
Image Naming
|
|
============
|
|
|
|
Both image name and volume id are generated based on the configuration. Since
|
|
the volume id is limited to 32 characters, there are more settings available.
|
|
The process for generating volume id is to get a list of possible formats and
|
|
try them sequentially until one fits in the length limit. If substitutions are
|
|
configured, each attempted volume id will be modified by it.
|
|
|
|
For layered products, the candidate formats are first
|
|
``image_volid_layered_product_formats`` followed by ``image_volid_formats``.
|
|
Otherwise, only ``image_volid_formats`` are tried.
|
|
|
|
If no format matches the length limit, an error will be reported and compose
|
|
aborted.
|
|
|
|
Options
|
|
-------
|
|
|
|
**image_name_format** [optional]
|
|
(*str*) -- Python's format string to serve as template for image names
|
|
|
|
This format will be used for all phases generating images. Currently that
|
|
means ``createiso``, ``live_images`` and ``buildinstall``.
|
|
|
|
Available keys are:
|
|
* compose_id
|
|
* variant
|
|
* arch
|
|
* disc_type
|
|
* disc_num
|
|
* suffix
|
|
* release_short
|
|
* version
|
|
|
|
**image_volid_formats** [optional]
|
|
(*list*) -- A list of format strings for generating volume id.
|
|
|
|
The available keys are:
|
|
* compose_id
|
|
* variant
|
|
* arch
|
|
* disc_type
|
|
* release_short
|
|
* version
|
|
* base_product_short
|
|
* base_product_version
|
|
|
|
**image_volid_layered_product_formats** [optional]
|
|
(*list*) -- A listof format strings for generating volume id for layered
|
|
products. The keys available are the same as for ``image_volid_formats``.
|
|
|
|
**volume_id_substitutions** [optional]
|
|
(*dict*) -- A mapping of string replacements to shorten the volume id.
|
|
|
|
Example
|
|
-------
|
|
::
|
|
|
|
# Image name respecting Fedora's image naming policy
|
|
image_name_format = "%(release_short)s-%(variant)s-%(disc_type)s-%(arch)s-%(version)s%(suffix)s"
|
|
# Use the same format for volume id
|
|
image_volid_formats = [
|
|
"%(release_short)s-%(variant)s-%(disc_type)s-%(arch)s-%(version)s"
|
|
]
|
|
# No special handling for layered products, use same format as for regular images
|
|
image_volid_layered_product_formats = []
|
|
# Replace "Cloud" with "C" in volume id etc.
|
|
volume_id_substitutions = {
|
|
'Cloud': 'C',

|
|
|
|
|

|
|
|
|
**pkgset_source** [mandatory]
|
|
(*str*) -- "koji" (any koji instance) or "repos" (arbitrary yum repositories)
|
|
|
|

|
|
|
|
**pkgset_koji_inherit** = True
|

|
::
|
|
|

pkgset_koji_tag = "f23"
|
|
|
|
|
|
Buildinstall Settings
|
|
=====================
|
|
Script or process that creates bootable images with
|
|
Anaconda installer is historically called
|
|
`buildinstall <https://git.fedorahosted.org/cgit/anaconda.git/tree/scripts/buildinstall?h=f15-branch>`_.
|
|
|
|
Options:
|
|
--------
|
|
|
|
**bootable**
|
|
(*bool*) -- whether to run the buildinstall phase
|
|
**buildinstall_method**
|
|
(*str*) -- "lorax" (f16+, rhel7+) or "buildinstall" (older releases)
|
|
**buildinstall_upgrade_image** [deprecated]
|
|
(*bool*) -- use ``noupgrade`` with ``lorax_options`` instead
|
|
**lorax_options**
|
|
(*list*) -- special options passed on to *lorax*.
|
|
|
|
Format: ``[(variant_uid_regex, {arch|*: {option: name}})]``.
|
|
|
|
Recognized options are:
|
|
* ``bugurl`` -- *str* (default ``None``)
|
|
* ``nomacboot`` -- *bool* (default ``True``)
|
|
* ``noupgrade`` -- *bool* (default ``True``)
|
|
|
|
Example
|
|
-------
|
|
::
|
|
|
|
bootable = True
|
|
buildinstall_method = "lorax"
|
|
|
|
# Enables macboot on x86_64 for all variants and builds upgrade images
|
|
# everywhere.
|
|
lorax_options = [
|
|
("^.*$", {
|
|
"x86_64": {
|
|
"nomacboot": False
|
|
}
|
|
"*": {
|
|
"noupgrade": False
|
|
}
|
|
})
|
|
]
|
|
|
|
|
|
.. note::
|
|
|
|
It is advised to run buildinstall (lorax) in koji,
|
|
i.e. with **runroot enabled** for clean build environments, better logging, etc.
|
|
|
|
|
|
.. warning::
|
|
|
|
Lorax installs RPMs into a chroot. This involves running %post scriptlets
|
|
and they frequently run executables in the chroot.
|
|
If we're composing for multiple architectures, we **must** use runroot for this reason.

|
to additional_packages, filter_packages, multilib_blacklist and multilib_whitelist
|
|
to track decisions.

Productimg Settings
|
|
===================
|
|
Product images are placed on installation media and provide additional branding
|
|
and Anaconda changes specific to product variants.
|
|
|
|
Options
|
|
-------
|
|
|
|
**productimg** = False
|
|
(*bool*) -- create product images; requires bootable=True

CreateISO Settings
|
|
==================
|
|
|
|
Options
|
|
-------
|
|
|
|
**createiso_skip** = False
|
|
(*list*) -- mapping that defines which variants and arches to skip during createiso; format: [(variant_uid_regex, {arch|*: True})]
|
|
|
|
**create_jigdo** = True
|
|
(*bool*) -- controls the creation of jigdo from ISO
|
|
|
|
.. note::
|
|
|
|
Source architecture needs to be listed explicitly.
|
|
Excluding '*' applies only on binary arches.
|
|
Jigdo causes significant increase of time to ISO creation.
|
|
|
|
|
|
Example
|
|
-------
|
|
::
|
|

Image Build Settings
|
|
====================
|
|
|
|
**image_build**
|
|
(*list*) -- config for koji image-build; format: [(variant_uid_regex, {arch|*: [{opt: value}])]
|
|
|
|
.. note::
|
|
Config can contain anything what is accepted by
|
|
``koji image-build --config configfile.ini``
|
|
|
|
Repo is currently the only option which is being automatically transformed
|
|
into a string.
|
|
|
|
Please don't set install_tree as it would get overriden by pungi.
|
|
The 'format' attr is [('image_type', 'image_suffix'), ...].
|
|
productmd should ideally contain all of image types and suffixes.
|
|
|
|
If ``ksurl`` ends with ``#HEAD``, Pungi will figure out the SHA1 hash of
|
|
current HEAD and use that instead.
|
|
|
|
|
|
Example
|
|
-------

Media Checksums Settings
|
|
========================
|
|
|
|
**media_checksums**
|
|
(*list*) -- list of checksum types to compute, allowed values are ``md5``,
|
|
``sha1`` and ``sha256``
|
|
|
|
**media_checksum_one_file**
|
|
(*bool*) -- when ``True``, only one ``CHECKSUM`` file will be created per
|
|
directory; this option requires ``media_checksums`` to only specify one
|
|
type
|
|
|
|
**media_checksum_base_filename**
|
|
(*str*) -- when not set, all checksums will be save to a file named either
|
|
``CHECKSUM`` or based on the digest type; this option allows adding any
|
|
prefix to that name
|
|
|
|
It is possible to use format strings that will be replace by actual values.
|
|
The allowed keys are ``%(release_showrt)s``, ``%(release_short)s``,
|
|
``%(release_id)s``, ``%(variant)s``, ``%(version)s``, ``%(date)s``,
|
|
``%(type_suffix)s`` and ``%(respin)s``
|
|
|
|
For example, for Fedora the prefix should be
|
|
``%(release_short)s-%(variant)s-%(version)s-%(date)s%(type_suffix)s.%(respin)s``.
|
|
|
|
|
|
Translate Paths Settings
|
|
========================
|
|
|
|
**translate_paths**
|
|
(*list*) -- list of paths to translate; format: [(path,translated_path)]
|
|
|
|
.. note::
|
|
This feature becomes useful when you need to transform compose location
|
|
into e.g. a http repo which is can be passed to koji image-build.
|
|
Translation needs to be invoked by a function call in pungi.
|
|
os.path.normpath() is applied on both path and translated_path
|
|
|
|
|
|
Example config
|
|
--------------
|
|
::
|
|
|
|
translate_paths = [
|
|
("/mnt/a", "http://b/dir"),
|
|
]
|
|
|
|
Example usage
|
|
-------------
|
|
::
|
|
|
|
>>> from pungi.paths import translate_paths
|
|
>>> print translate_paths(compose_object_with_mapping, "/mnt/a/c/somefile")
|
|
http://b/dir/c/somefile
