Trying to enable testing specs for 9.0, we've encountered different unavoidable problems with existing checks. For example, it was impossible to have code blocks with line length more than 80 characters. This commit uses docutils and make those changes using AST, so we can avoid some checks for code-blocks or long links. Closes-Bug: #1569929 Change-Id: Ia501754922b3272acd1a865513d5dffa17981331

Remove CentOS bootstrap from Fuel

Problem description
|
|
--------------------
|
|
|
|
At the moment we build Centos bootstrap OS image together with ISO and then
|
|
package it into rpm. Since Fuel 8.0 we switched to Ubuntu bootstrap image
|
|
usage [1]_ and CentOS one became deprecated, so in Fuel 9.0 we can freely
|
|
remove it [2]_.
|
|
|
|
By removing fuel-bootstrap-image [2]_ we:
|
|
|
|
* simplify patching/update story, since we don't need to rebuild/deliver this
|
|
package on changes in dependent packages [3]_.
|
|
|
|
* speed-up ISO build process, since building centos bootstrap image takes ~ 20%
|
|
of build-iso time.
|
|

Proposed changes
|
|
----------------
|
|
|
|
Remove CentOS bootstrap image usage from Fuel projects.

Fuel Library
|
|
============
|
|
|
|
* CentOS cobbler profiles should be removed from fuel-library code
|
|
* The default `bootstrap_profile` should be set to `ubuntu_bootstrap`

|
Alternatives
|
|
------------
|
|
|
|
Currently we build Ubuntu bootstrap OS image on the master node using
|
|
Fuel Agent. Although Fuel Agent does not support building Centos images
|
|
we can implement such functionality.
|
|
|
|
We need to implement build image utilities for Centos and modify Fuel Agent
|
|
build image manager method and probably input data driver so as to make it
|
|
possible to use Fuel Agent to build Centos images.

|
Upgrade impact
|
|
--------------
|
|
|
|
We no longer need to deliver/update fuel-bootstrap-image package [2], this will
|
|
simplify patching/update story, since we don't need to rebuild this package on
|
|
each changes in any dependent packages [3]_:
|
|
|
|
* fuel-agent;
|
|
* nailgun-agent;
|
|
* nailgun-mcagents;
|
|
* network-checker;
|

* rubygem-ffi-yajl;

* rubygem-ffi;

* rubygem-mime-types;
