|
||
|
||
Anaconda is the installation program used by Fedora, Red Hat Enterprise Linux and link:anaconda_distros.html[some other distributions].
|
||
|
||
During installation, a target computer's hardware is identified and configured, and the appropriate file systems for the system's architecture are created.
|
||
Finally, Anaconda allows the user to install the operating system software on the target computer.
|
||
Anaconda can also upgrade existing installations of earlier versions of the same distribution.
|
||
After the installation is complete, you can reboot into your installed system and continue doing customization using https://fedoraproject.org/wiki/InitialSetup[initial setup].
|
||
|
||
Anaconda is a fairly sophisticated installer.
|
||
It supports installation from local and remote sources such as CDs and DVDs, images stored on a hard drive, NFS, HTTP, and FTP.
|
||
Installation can be scripted with http://pykickstart.readthedocs.io/en/latest/[kickstart] to provide a fully unattended installation that can be duplicated on scores of machines.
|
||
It can also be run over VNC on headless machines.
|
||
A variety of advanced storage devices including LVM, RAID, iSCSI, and multipath are supported from the partitioning program.
|
||
Anaconda provides advanced debugging features such as remote logging, access to the python interactive debugger, and remote saving of exception dumps.

== Users
|
||
|
||
If you are a user having problems with Anaconda, please use the user support forum for your distribution such as http://forums.fedoraforum.org/forumdisplay.php?f=6[Fedora Forum] or https://lists.fedoraproject.org/admin/lists/users.lists.fedoraproject.org/[the fedora-users mailing list].
|
||
|
||
From time to time, we may distribute updates for Anaconda to fix problems in Fedora releases.
|
||

== Mailing Lists
|
||
|
||
There are two mailing lists for Anaconda.
|
||
The first is the development mailing list.
|
||
This list is used to discuss development issues, submit patches, and other activities related to extending Anaconda.
|
||
The sign up for the development list is located at https://listman.redhat.com/mailman/listinfo/anaconda-devel-list[anaconda development list site].
|
||
Past discussions can be found in the https://www.redhat.com/archives/anaconda-devel-list[anaconda development archives].
|
||
|
||
The second list is a user oriented list on how to create kickstart files.
|
||
The kickstart list is the place to discuss automated installation issues.
|
||
The sign up for the kickstart list is located at https://www.redhat.com/mailman/listinfo/kickstart-list[anaconda kickstart list site].
|
||
Past discussions can be found in the https://www.redhat.com/archives/kickstart-list[anaconda kickstart archives].
|
||
|
||
Patch review used to take place on a mailing list dedicated to submitting and reviewing patches.
|
||
Patch review now takes place on https://github.com/rhinstaller/anaconda/pulls[GitHub] via pull requests.
|
||
Past discussions of patches can be found in the https://lists.fedorahosted.org/pipermail/anaconda-patches/[anaconda-patches archives], which is the main purpose this mailing list now serves.
|
||
|
||
[id="irc"]
|
||
== IRC
|
||
|
||
There is also an IRC channel on link:http://freenode.net[FreeNode].
|
||
This resource is for discussion of Anaconda development, not for distribution customization questions.
|
||
|

[id="how-to-contribute"]
|
||
== How to Contribute
|
||
|
||
For how to contribute to Anaconda and related projects, see the https://anaconda-installer.readthedocs.io/en/latest/contributing.html[Contributing to Anaconda and related projects] documentation.
|
||
|
||
Please note that useful contributions are not limited to submitting patches for source code.
|
||
You can also help with https://anaconda-installer.readthedocs.io/en/latest/testing.html[testing], reporting bugs, improving translations or extending the Anaconda documentation.
|
||
|
||
[id="developers-guide"]
|
||
== Developers' Guide
|
||
|
||
Anaconda is now almost entirely written in Python 3.
|
||
The graphical front end uses GTK+ 3 via gobject-introspection, and as much of the interface as possible is written using the glade interface builder.
|
||
The earliest parts of Anaconda are in shell for integration with dracut, and there's still a little bit of C thrown in for interfacing with certain libraries.
|
||
|
||
Here are some documents if you are planning on working on Anaconda.
|
||
More are in the works:
|
||
|
||
* Anaconda/Devel/Translation
|
||
* If you want to work on Anaconda, you should start with the Anaconda/SourceOverview[Source Overview], which contains a high level discussion of the source files and what they do.
|
||
|
||
Then look at the https://anaconda-installer.readthedocs.io/en/latest/[online documentation] for information on how to test, debug, and develop anaconda.
|
||
|
||
Familiarize yourself with the tools that Anaconda uses.
|
||
Check out the following external reference documents:
|
||
|
||
* https://developer.gnome.org/gtk3/stable/[GTK+ reference]
|
||
* https://docs.python.org/3/tutorial/[Python tutorial]
|
||
* https://docs.python.org/3/py-modindex.html[Python module reference]

|
||
== Getting the Source
|
||
|
||
The primary methods of distributing the Anaconda source are source RPMs in the http://dl.fedoraproject.org/pub/fedora/linux/development/rawhide/source/SRPMS/[Fedora development tree] and git.
|
||
To access the current source code in in non-rpm format, you'll need to install git.
|
||
|
||
[source,bash]
|
||
----
|
||
$ dnf install git
|
||
----
|
||
|
||
Note that several related packages will be installed as well.
|
||
After the git source code management tool has been installed, then you use anonymous git access to the Anaconda repository.
|
||
|
||
If you would just like to browse the Anaconda git repository via the web, then please use the following https://github.com/rhinstaller/anaconda.git[Anaconda git URL].
|
||
|
||
[source,bash]
|
||
----
|
||
$ git clone https://github.com/rhinstaller/anaconda.git
|
||
----
|
||
|
||
The output may look similar to the following:
|
||
|
||
----
|
||

|
||
If you have committer access to Anaconda, then you will want to use the git+ssh access url.
|
||
(GitHub also supports pushing changes via HTTPS, but may require you to re-authenticate every time you push your changes.)
|
||
|
||
[source,bash]
|
||
----
|
||
$ git clone git+ssh://git@github.com/rhinstaller/anaconda.git
|
||
----
|
||
|
||
Once you've committed changes locally, you can push them with
|
||
|
||
[source,bash]
|
||
----
|
||
$ git push
|
||
----
|
||
|
||
|
||
Anaconda has an https://github.com/rhinstaller/kickstart-tests[extensive suite of tests] that is still growing.
|
||
If you contribute new functionality, it's good practice to include some tests along with that.
|
||
We have a https://anaconda-installer.readthedocs.io/en/latest/testing.html[document that outlines the test suite infratructure and describes how to run tests].
|
||
|
||
To contribute you should read our https://anaconda-installer.readthedocs.io/en/latest/contributing.html[guidelines for contributing].
