Release
=======
Following **mandatory** options describe a release.
Options
-------
**release_name** [mandatory]
(*str*) -- release name
**release_short** [mandatory]
(*str*) -- release short name, without spaces and special characters
**release_version** [mandatory]
(*str*) -- release version
**release_type** = "ga"
(*str*) -- release type, "ga" or "updates"
**release_is_layered** = False
(*bool*) -- typically False for an operating system, True otherwise
Example
-------
::
release_name = "Fedora"
release_short = "Fedora"
release_version = "23"
# release_type = "ga"
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.
Options
-------
**base_product_name**
(*str*) -- base product name
**base_product_short**
(*str*) -- base product short name, without spaces and special characters
**base_product_version**
(*str*) -- base product **major** version
Example
-------
::
release_name = "RPM Fusion"
release_short = "rf"
release_version = "23.0"
release_is_layered = True
base_product_name = "Fedora"
base_product_short = "Fedora"
base_product_version = "23"
**tree_arches**
([*str*]) -- list of architectures which should be included; if undefined, all architectures from variants.xml will be included
**tree_variants**
([*str*]) -- list of variants which should be included; if undefined, all variants from variants.xml will be included
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
**failable_deliverables** [optional]
(*list*) -- list which deliverables on which variant and architecture can
fail and not abort the whole compose
Currently handled deliverables are:
* buildinstall
* iso
* live
* image-build
* live-media
* atomic_installer
.. note::
Image building is not run per-architecture. If you want to mark it
as failable, specify it in a block with arch set as ``*``.
Please note that ``*`` as a wildcard matches all architectures but ``src``.
tree_arches = ["x86_64"]
tree_variants = ["Server"]
**comps_filter_environments** [optional]
(*bool*) -- When set to ``False``, the comps files for variants will not
have their environments filtered to match the variant.
**keep_original_comps** [optional]
(*list*) -- List of variants for which the original comps file will be
copied without any modifications. Overwrites `comps_filter_environments`.
Example
-------
::
comps_file = {
"scm": "git",
"repo": "https://git.fedorahosted.org/git/comps.git",
"branch": None,
"file": "comps-f23.xml.in",
}
variants_file = {
"scm": "git",
"repo": "https://pagure.io/pungi-fedora.git ",
"branch": None,
"file": "variants-fedora.xml",
}
failable_deliverables = [
('^.*$', {
# Buildinstall can fail on any variant and any arch
'*': ['buildinstall'],
'src': ['buildinstall'],
# Nothing on i386 blocks the compose
'i386': ['buildinstall', 'iso', 'live'],
})
]
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
-------
There a couple common format specifiers available for both the options:
* ``compose_id``
* ``release_short``
* ``version``
* ``date``
* ``respin``
* ``type``
* ``type_suffix``
* ``label``
* ``label_major_version``
* ``variant``
* ``arch``
* ``disc_type``
**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 extra keys are:
* ``disc_num``
* ``suffix``
**image_volid_formats** [optional]
(*list*) -- A list of format strings for generating volume id.
The extra available keys are:
* ``base_product_short``
* ``base_product_version``
**image_volid_layered_product_formats** [optional]
(*list*) -- A list of 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.
**disc_types** [optional]
(*dict*) -- A mapping for customizing ``disc_type`` used in image names.
Available keys are:
* ``boot`` -- for ``boot.iso`` images created in *buildinstall* phase
* ``live`` -- for images created by *live_images* phase
* ``dvd`` -- for images created by *createiso* phase
Default values are the same as the keys.
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',
'Alpha': 'A',
'Beta': 'B',
'TC': 'T',
}
disc_types = {
'boot': 'netinst',
'live': 'Live',
'dvd': 'DVD',
}
Signing
=======
If you want to sign deliverables generated during pungi run like RPM wrapped
images. You must provide few configuration options:
**signing_command** [optional]
(*str*) -- Command that will be run with a koji build as a single
argument. This command must not require any user interaction.
If you need to pass a password for a signing key to the command,
do this via command line option of the command and use string
formatting syntax ``%(signing_key_password)s``.
(See **signing_key_password_file**).
**signing_key_id** [optional]
(*str*) -- ID of the key that will be used for the signing.
This ID will be used when crafting koji paths to signed files
(``kojipkgs.fedoraproject.org/packages/NAME/VER/REL/data/signed/KEYID/..``).
**signing_key_password_file** [optional]
(*str*) -- Path to a file with password that will be formatted
into **signing_command** string via ``%(signing_key_password)s``
string format syntax (if used).
Because pungi config is usualy stored in git and is part of compose
logs we don't want password to be included directly in the config.
Note: If ``-`` string is used instead of a filename, then you will be asked
for the password interactivelly right after pungi starts.
Example
-------
::
signing_command = '~/git/releng/scripts/sigulsign_unsigned.py -vv --password=%(signing_key_password)s fedora-24'
signing_key_id = '81b46521'
signing_key_password_file = '~/password_for_fedora-24_key'
Git URLs
========
In multiple places the config requires URL of a Git repository to download
kickstart file from. This URL is passed on to *Koji*. It is possible to which
commit to use using this syntax: ::
git://git.example.com/git/repo-name.git?#<rev_spec>
The ``<rev_spec>`` pattern can be replaced with actual commit SHA, a tag name,
``HEAD`` to indicate that tip of default branch should be used or
``origin/<branch_name>`` to use tip of arbitrary branch.
If the URL specifies a branch or ``HEAD``, *Pungi* will replace it with the
actual commit SHA. This will later show up in *Koji* tasks and help with
tracing what particular inputs were used.
.. note::
The ``origin`` must be specified because of the way *Koji* works with the
repository. It will clone the repository then switch to requested state
with ``git reset --hard REF``. Since no local branches are created, we need
to use full specification including the name of the remote.
Createrepo Settings
===================
Options
-------
**createrepo_checksum** [mandatory]
(*str*) -- specify checksum type for createrepo; expected values: sha256, sha
**createrepo_c** = True
(*bool*) -- use createrepo_c (True) or legacy createrepo (False)
**createrepo_deltas** = False
(*bool*) -- generate delta RPMs against an older compose. This needs to be
used together with `--old-composes`` command line argument.
Example
-------
::
createrepo_checksum = "sha256"
Package Set Settings
====================
Options
-------
**sigkeys**
([*str* or None]) -- priority list of sigkeys, *None* means unsigned
**pkgset_source** [mandatory]
(*str*) -- "koji" (any koji instance) or "repos" (arbitrary yum repositories)
**pkgset_koji_tag** [mandatory]
(*str*) -- tag to read package set from
**pkgset_koji_inherit** = True
(*bool*) -- inherit builds from parent tags; we can turn it off only if we have all builds tagged in a single tag
Example
-------
::
sigkeys = [None]
pkgset_source = "koji"
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.
Gather Settings
===============
Options
-------
**gather_source** [mandatory]
(*str*) -- from where to read initial package list; expected values: "comps", "none"
**gather_method** [mandatory]
(*str*) -- "deps", "nodeps"
**greedy_method**
(*str*) -- see :doc:`gather`, recommended value: "build"
**multilib_methods** [deprecated]
([*str*]) -- use ``multilib`` instead to configure this per-variant
**multilib_arches** [deprecated]
([*str*] or None) -- use ``multilib`` to implicitly configure this: if a
variant on any arch has non-empty multilib methods, it is automatically
eligible
**multilib**
(*list*) -- mapping of variant regexes and arches to list of multilib
methods
Available methods are:
* ``none``
* ``all``
* ``runtime``
* ``file``
* ``kernel``
* ``yaboot``
**additional_packages**
(*list*) -- additional packages to be included in a variant and
architecture; format: ``[(variant_uid_regex, {arch|*: [package_globs]})]``
**filter_packages**
(*list*) -- packages to be excluded from a variant and architecture;
format: ``[(variant_uid_regex, {arch|*: [package_globs]})]``
**filter_system_release_packages**
(*bool*) -- for each variant, figure out the best system release package
and filter out all others. This will not work if a variant needs more than
one system release package. In such case, set this option to ``False``.
**multilib_blacklist**
(*dict*) -- multilib blacklist; format: ``{arch|*: [package_globs]}``. The
patterns are tested with ``fnmatch``, so shell globbing is used (not
regular expression).
**multilib_whitelist**
(*dict*) -- multilib blacklist; format: ``{arch|*: [package_names]}``. The
whitelist must contain exact package names; there are no wildcards or
pattern matching.
**gather_lookaside_repos** = []
(*list*) -- lookaside repositories used for package gathering; format:
``[(variant_uid_regex, {arch|*: [repo_urls]})]``
**hashed_directories** = False
(*bool*) -- put packages into "hashed" directories, for example
``Packages/k/kernel-4.0.4-301.fc22.x86_64.rpm``
Example
-------
::
gather_source = "comps"
gather_method = "deps"
greedy_method = "build"
check_deps = False
hashed_directories = True
additional_packages = [
# bz#123456
('^(Workstation|Server)$', {
'*': [
'grub2',
'kernel',
],
}),
]
filter_packages = [
# bz#111222
('^.*$', {
'*': [
'kernel-doc',
],
}),
]
multilib = [
('^Server$', {
'x86_64': ['devel', 'runtime']
})
]
multilib_blacklist = {
"*": [
"gcc",
],
}
multilib_whitelist = {
"*": [
"alsa-plugins-*",
],
}
# gather_lookaside_repos = [
# ('^.*$', {
# 'x86_64': [
# "https://dl.fedoraproject.org/pub/fedora/linux/releases/22/Everything/x86_64/os/",
# "https://dl.fedoraproject.org/pub/fedora/linux/releases/22/Everything/source/SRPMS/",
# ]
# }),
# ]
.. note::
It is a good practice to attach bug/ticket numbers
to additional_packages, filter_packages, multilib_blacklist and multilib_whitelist
to track decisions.
Koji Settings
=============
Options
-------
**koji_profile**
(*str*) -- koji profile name
**runroot** [mandatory]
(*bool*) -- run some tasks such as buildinstall or createiso in koji build root (True) or locally (False)
**runroot_channel**
(*str*) -- name of koji channel
**runroot_tag**
(*str*) -- name of koji **build** tag used for runroot
Example
-------
::
koji_profile = "koji"
runroot = True
runroot_channel = "runroot"
runroot_tag = "f23-build"
Extra Files Settings
====================
Options
-------
**extra_files**
(*list*) -- references to external files to be placed in os/ directory and media; format: [(variant_uid_regex, {arch|*: [scm_dicts]})]
Example
-------
::
extra_files = [
('^.*$', {
'*': [
# GPG keys
{
"scm": "rpm",
"repo": "fedora-repos",
"branch": None,
"file": [
"/etc/pki/rpm-gpg/RPM-GPG-KEY-22-fedora",
],
"target": "",
},
# GPL
{
"scm": "git",
"repo": "https://pagure.io/pungi-fedora",
"branch": None,
"file": [
"GPL",
],
"target": "",
},
],
}),
]
Productimg Settings
===================
Product images are placed on installation media and provide additional branding
and Anaconda changes specific to product variants.
Options
-------
**productimg** = False
(*bool*) -- create product images; requires bootable=True
**productimg_install_class**
(*scm_dict*, *str*) -- reference to install class **file**
**productimg_po_files**
(*scm_dict*, *str*) -- reference to a **directory** with po files for install class translations
Example
-------
::
productimg = True
productimg_install_class = {
"scm": "git",
"repo": "http://git.example.com/productimg.git",
"branch": None,
"file": "fedora23/%(variant_id)s.py",
}
productimg_po_files = {
"scm": "git",
"repo": "http://git.example.com/productimg.git",
"branch": None,
"dir": "po",
}
CreateISO Settings
==================
Options
-------
**createiso_skip** = False
(*list*) -- mapping that defines which variants and arches to skip during createiso; format: [(variant_uid_regex, {arch|*: True})]
**create_jigdo** = True
(*bool*) -- controls the creation of jigdo from ISO
.. note::
Source architecture needs to be listed explicitly.
Excluding '*' applies only on binary arches.
Jigdo causes significant increase of time to ISO creation.
Example
-------
::
createiso_skip = [
('^Workstation$', {
'*': True,
'src': True
}),
]
Live Images Settings
====================
**live_target**
(*str*) -- Koji build target for which to build the images. This gets
passed to ``koji spin-livecd``.
**live_images**
(*list*) -- Configuration for the particular image. The elements of the
list should be tuples ``(variant_uid_regex, {arch|*: config})``. The config
should be a dict with these keys:
* ``kickstart`` (*str*)
* ``ksurl`` (*str*) [optional] -- where to get the kickstart from
* ``name`` (*str*)
* ``version`` (*str*)
* ``additional_repos`` (*list*) -- external repos specified by URL
* ``repo_from`` (*list*) -- repos from other variants
* ``specfile`` (*str*) -- for images wrapped in RPM
* ``scratch`` (*bool*) -- only RPM-wrapped images can use scratch builds,
but by default this is turned off
* ``type`` (*str*) -- what kind of task to start in Koji. Defaults to
``live`` meaning ``koji spin-livecd`` will be used. Alternative option
is ``appliance`` corresponding to ``koji spin-appliance``.
* ``sign`` (*bool*) -- only RPM-wrapped images can be signed
**live_images_no_rename**
(*bool*) -- When set to ``True``, filenames generated by Koji will be used.
When ``False``, filenames will be generated based on ``image_name_format``
configuration option.
Live Media Settings
===================
**live_media**
(*dict*) -- configuration for ``koji spin-livemedia``; format:
``{variant_uid_regex: [{opt:value}]}``
Required options:
* ``name`` (*str*)
* ``version`` (*str*)
* ``target`` (*str*)
* ``arches`` (*[str]*) -- what architectures to build the media for; by default uses
all arches for the variant.
* ``kickstart`` (*str*) -- name of the kickstart file
Available options:
* ``ksurl`` (*str*)
* ``ksversion`` (*str*)
* ``scratch`` (*bool*)
* ``release`` (*str*) -- a string with the release, or explicit ``None``
for using compose date and respin.
* ``skip_tag`` (*bool*)
* ``repo`` (*[str]*) -- external repo
* ``repo_from`` (*[str]*) -- list of variants to take extra repos from
* ``title`` (*str*)
* ``install_tree_from`` (*str*) -- variant to take install tree from
If many of your media use the same value for one of ``ksurl``, ``release``,
``target`` or ``version``, consider using these options to set the value in one
place and have all media inherit it.
**live_media_ksurl**
(*str*) -- Provides a fallback for media that do not specify ``ksurl`` in
the ``live_media`` block.
**live_media_release**
(*str*) -- Provides a fallback for media that do not specify ``release`` in
the ``live_media`` block. Please note that if you set this, there is no way
to unset it for a particular media. This is important if you want the
release generated by Koji.
**live_media_target**
(*str*) -- Provides a fallback for media that do not specify ``target`` in
the ``live_media`` block.
**live_media_version**
(*str*) -- Provides a fallback for media that do not specify ``version`` in
the ``live_media`` block.
Image Build Settings
====================
**image_build**
(*dict*) -- config for ``koji image-build``; format: {variant_uid_regex: [{opt: value}]}
By default, images will be built for each binary arch valid for the
variant. The config can specify a list of arches to narrow this down.
.. note::
Config can contain anything what is accepted by
``koji image-build --config configfile.ini``
Repo can be specified either as a string or a list of strings. It will be
automatically transformed into format suitable for ``koji``. A repo for the
currently built variant will be added as well.
If you explicitly set ``release`` to ``None``, it will be replaced with
``DATE.RESPIN`` of the current compose.
You can also add extra variants to get repos from with key ``repo_from``.
The value should be a list of variant names.
Please don't set ``install_tree``. This gets automatically set by *pungi*
based on current variant. You can use ``install_tree_from`` key to use
install tree from another variant.
The ``format`` attr is [('image_type', 'image_suffix'), ...].
See productmd documentation for list of supported types and suffixes.
If ``ksurl`` ends with ``#HEAD``, Pungi will figure out the SHA1 hash of
current HEAD and use that instead.
Setting ``scratch`` to ``True`` will run the koji tasks as scratch builds.
Example
-------
::
image_build = {
'^Server$': [
{
'image-build': {
'format': [('docker', 'tar.gz'), ('qcow2', 'qcow2')]

}
]
}
OSTree Settings
===============
The ``ostree`` phase of *Pungi* can create ostree repositories in a Koji
runroot environment.
**ostree**
(*dict*) -- a variant/arch mapping of configuration. The format should be
``[(variant_uid_regex, {arch|*: config_dict})]``.
The configuration dict for each variant arch pair must have these keys:
* ``treefile`` -- (*str*) Filename of configuration for ``rpm-ostree``.
* ``config_url`` -- (*str*) URL for Git repository with the ``treefile``.
* ``source_repo_from`` -- (*str*) Name of variant serving as source repository.
* ``atomic_repo`` -- (*str*) Where to put the atomic repository
These keys are optional:
* ``config_branch`` -- (*str*) Git branch of the repo to use. Defaults to
``master``.
Example config
--------------
::
ostree = [
("^Atomic$", {
"x86_64": {

Atomic Installer Settings
=========================
The ``atomic_installer`` phase of *Pungi* can produce installer image bundling
an OSTree repository. This always runs in Koji as a ``runroot`` task.
**atomic**
(*dict*) -- a variant/arch mapping of configuration. The format should be
``[(variant_uid_regex, {arch|*: config_dict})]``.
The configuration dict for each variant arch pair must have this key:
* ``source_repo_from`` -- (*str*) Name of variant serving as source
repository.
These keys are optional:
* ``release`` -- (*str*) Release value to set for the installer image. Set
to ``None`` to use the date.respin format.
* ``filename`` -- (*str*) What to name the installer iso. This is a
template with options listed in Image naming section. If not specified,
global naming format will be used.
These optional keys are passed to ``lorax`` to customize the build.
* ``installpkgs`` -- (*[str]*)
* ``add_template`` -- (*[str]*)
* ``add_arch_template`` -- (*[str]*)
* ``add_template_var`` -- (*[str]*)
* ``add_arch_template_var`` -- (*[str]*)
Example config
--------------
::
atomic = [
("^Atomic$", {
"x86_64": {
"source_repo_from": "Everything",
"release": None,
"filename": "%(release_short)s-%(variant)s-%(arch)s-%(version)s-%(compose_date)s.iso",
"installpkgs": ["fedora-productimg-atomic"],
"add_template": ["/spin-kickstarts/atomic-installer/lorax-configure-repo.tmpl"],
"add_template_var": [
"ostree_osname=fedora-atomic",
"ostree_ref=fedora-atomic/Rawhide/x86_64/docker-host",
],
"add_arch_template": ["/spin-kickstarts/atomic-installer/lorax-embed-repo.tmpl"],
"add_arch_template_var": [
"ostree_repo=https://kojipkgs.fedoraproject.org/compose/atomic/Rawhide/",
"ostree_osname=fedora-atomic",
"ostree_ref=fedora-atomic/Rawhide/x86_64/docker-host",
]
}
})
]
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``, ``%(label)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``.
The ``path`` part is normalized via ``os.path.normpath()``.
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
