Puppet class browser
Version 3 (Paul Kelly, 05/10/2010 04:42 pm)
h1. Puppet class browser
There are links labeled "Documentation" on the *settings/puppet classes* page, which will direct your browser to the html documentation for a particular puppet module.
The documentation is generated by a rake task that uses the puppetdoc utility and may need some customization to work at a particular site.
h3. Document root
There is an optional entry in the config/settings.yaml which overrides the location of the generated HTML pages. The default value is *RAILS_ROOT/public* which relies upon the rails built-in web server.
The documentation will be written into *document_root*/puppet/rdoc and this location must be in an area that is served by a web server. Any location that is served by apache or webrick/mongrel will do, and foreman's *public* directory is the default.
h3. manifest cleanup
The puppetdoc utility is sensitive to the layout of the manifests and modules directories. In particular, it cannot handle circular or broken symlinks. If you have problems running puppetdoc then move *extras/rdoc/rdoc_prepare_script.rb* to *scripts/rdoc_prepare_script.rb* and then edit it to suit your site. Most sites will not require a scripts/rdoc_prepare_script.rb file.
h2. Generating the documentation.
h3. Simple case
This is performed by running
h3. Complex case
If the puppetdoc utility fails to process your manifests then you will have to sanitize your puppet modules directory. The rake puppet:rdoc:generate task will check for the existence of *scripts/rdoc_prepare_script.rb*, and runs this before the the puppetdoc command is executed. This script is expected to copy the source files for your modules to another location, fix any issues and then terminate, passing back the location of the copied directory tree.
A fairly complex example is provided in *extras/rdoc/rdoc_prepare_script.rb*.
The final command to generate the documentation is then the same as for the simple case
