"We want more!"

• Anaconda is the most comprehensive OS installer in the world.
• People still come up with ideas on what should be added.
• We are quite a small team with quite a huge and complex codebase.
• We don't know every corner of the system.
• Should the OS installer just install the OS or configure it thoroughly as well?
• Want to see something more in the installer?
  • Write an addon!

"Okay, okay, where should I start?"

• Attend the Extending the Anaconda installer DevConf 2014 workshop!
• the Anaconda Addon Development Guide (AADG)
• the HelloWorld Anaconda addon
• the OSCAP Anaconda addon
• ask on the anaconda-devel mailing list

"Any appetizer?"

• Let's have a look at the HelloWorld addon

$ git clone https://github.com/vpodzime/hello-world-anaconda-addon.git
$ cd hello-world-anaconda-addon
$ ll -R | less

...and of course browse the sources.

"Wait, is it really that simple?"

• Yes, it is!
• This is how pylint sees the org_fedora_hello_world/gui/spokes/hello_world.py file:

+----------+-------+------+
|type      |number |%     |
+==========+=======+======+
|code      |61     |26.18 |
+----------+-------+------+
|docstring |104    |44.64 |
+----------+-------+------+
|comment   |40     |17.17 |
+----------+-------+------+
|empty     |28     |12.02 |
+----------+-------+------+

• So ~50 lines of code are required and everything else is up to you.
• For example the OSCAP Anaconda Addon's spoke now has 387 lines of code, overall 4179 lines in python source files (including 70 unit tests).

"I really miss boot loader password configuration"

• install anaconda, anaconda-widgets, anaconda-widgets-devel packages
• create the directory structure and the __init__.py files
• Glade up your spoke
• write the necessary code
• Let's code! (https://github.com/vpodzime/boot-loader-anaconda-addon)
• Let's test it!
• submit patches for the Anaconda

Addons wish list

• subscription management, kdump
• realmd, firewalld addons
• easy setup of popular 3rd party repositories
• Copr, software collections
• upload assistant (screen shots, etc.)
• web browser addon
• IRC client addon
• package selection
• Emacs addon

"Where can I reach you, guys?"

• Right here, right now
• vpodzime@redhat.com
• anaconda-devel-list@redhat.com
• #anaconda @ Freenode
• Red Hat, Brno1, 4th floor
• Remember: Collaboration works!

Thank you for your attention!
