Wiki Modernization
|
||||
==================
|
||||
|
||||
https://storyboard.openstack.org/#!/story/2000641
|
||||
|
||||
The OpenStack wiki at wiki.openstack.org needs to be fully Puppetized,
|
||||
upgraded to the current stable version of MediaWiki and upgraded to a
|
||||
newer Ubuntu LTS version.
|
||||
|
||||
Problem Description
|
||||
===================
|
||||
|
||||
Vandalism to the wiki this year has highlighted the fact that we need to
|
||||
upgrade the wiki in order to apply modern security fixes and begin using
|
||||
modern spam fighting tools. In the short term, we have disabled new
|
||||
account creation but this is restricting the value of the wiki and
|
||||
unfairly disadvantaging new contributors.
|
||||
|
||||
It is current running on Ubuntu 12.04 and dependencies dictate that we
|
||||
upgrade to 14.04 in order to get the most recent version of MediaWiki.
|
||||
|
||||
The installation is also not fully Puppetized, so some parts of our
|
||||
maintenance and upgrade process are manual and not fully documented.
|
||||
|
||||
Proposed Change
|
||||
===============
|
||||
|
||||
This modernization effort has several components.
|
||||
|
||||
The full process of installation has to be Puppetized. Investigation
|
||||
needs to be done into the existing puppet-mediawiki modules to see if we
|
||||
should use and contribute to those, or continue building our in house
|
||||
module. The mediawiki package for Ubuntu will continue to not be used,
|
||||
since it's been dropped from Debian and the packaging and mediawiki
|
||||
community has indicated a preference for source-based installation.
|
||||
|
||||
Create new instance running Ubuntu 14.04 in order to move the wiki off
|
||||
of 12.04. Backups will need to be made of the current state of the wiki
|
||||
and data moved as needed.
|
||||
|
||||
Using our new Puppetized installation process, migrate the wiki content
|
||||
to the new version of mediawiki our module is using.
|
||||
|
||||
Optional: Evaluate continued use of the Ubuntu SSO mechanism for the
|
||||
wiki as we have no control over the compromised spam accounts coming in
|
||||
from that service..
|
||||
|
||||
Alternatives
|
||||
------------
|
||||
|
||||
Work with the community to move away from using a wiki at all and
|
||||
evaluate tooling to replace it.
|
||||
|
||||
Continue to use a wiki, but evaluate alternatives to MediaWiki and do a
|
||||
migration to that new platform.
|
||||
|
||||
Implementation

|
||||
Gerrit Topic
|
||||
------------
|
||||
|
||||
Use Gerrit topic "wiki-upgrade" for all patches related to this spec.
|
||||
|
||||
.. code-block:: bash
|
||||
|
||||
git-review -t wiki-upgrade
|
||||
|
||||
Work Items
|
||||
----------
|
||||
|
||||
* Evaluate state of PuppetForge puppet-mediawiki modules compared to
|
||||
ours.
|
||||
* Work to modernize selected puppet-mediawiki module so it fully meets
|
||||
our needs.
|
||||
* Bring up new wiki-dev.o.o instance running Ubuntu 14.04 to begin
|
||||
testing the new wiki, and use in the longer term to coordinate
|
||||
upgrades and new features.
|
||||
* Bring up new wiki.o.o instance running Ubuntu 14.04.
|
||||
* Come up with migration and rollback plan for data to new server and
|
||||
new version of MediaWiki.
|
||||
* Notification to the community around changes with new version and any
|
||||
changes to logging in to or using the wiki.
|
||||
* Complete final cutover to new server
|
||||
* Evaluate and try the popular, modern spam fighting plugins and
|
||||
techniques on the new server.
|
||||
|
||||
Repositories
|
||||
------------
|
||||
|
||||
Our existing puppet-mediawiki repository may be improved upon if we
|
||||
don't find a better third party module. No new repositories should be
|
||||
required.
|
||||
|
||||
Servers
|
||||
-------
|
||||
|
||||
A new wiki-dev.o.o server will be created.
|
||||
|
||||
The current wiki.o.o server will be replaced with a new one running
|
||||
Ubuntu 14.04.
|
||||
|
||||
|
||||
DNS Entries
|
||||
-----------
|
||||
|
||||
New wiki-dev.openstack.org A/AAAA records will need to be created.
|
||||
|
||||
Documentation
|
||||
-------------
|
||||
|
||||
Updates to our system-config documentation for the wiki will need to be
|
||||
completed.
|
||||
|
||||
Security
|
||||
--------
|
||||
|
||||
The goal is for security to be increased by this modernization work.
|
||||
|
||||
Testing
|
||||
-------
|
||||
|
||||
The introduction of the wiki-dev server will help us be more effective
|
||||
with changes made to the wiki server overall. Standard testing of Puppet
|
||||
modules will continue with the puppet-mediawiki module as before.
|
||||
|
||||
Automated tooling that updates the wiki will need to be tested and
|
||||
confirmed working.
