Hi Antonio,
First of all, thank you for your contribution. I would like to share with
you some comments ragarding this component.
In OpenNebula 4.2 we included the OneFlow [1] in the distribution. OneFlow
allows users and administrators to define, execute and manage multi-tiered
applications, or services composed of interconnected Virtual Machines with
deployment dependencies between them. Each group of Virtual Machines is
deployed and managed as a single entity. Maybe OneFlow can be used in your
use case.
Now some comments about the implementation, I really like the way you
integrated everything using the sunstone tabs, but I would try not to
modify existing files of the OpenNebula distribution. We provide plugins in
other parts of the stack to avoid modifying existing files, not only in the
sunstone tabs, for example:
* In VirtualClusterJSON.rb you are interacting directly with the OpenNebula
DB, but the only component interacting with the DB should be oned. For
this, we provide the DOCUMENT resource, this will allow you to use
OpenNebula as a DB and use all the OpenNebula permissions system, you just
have to define a DOCUMENT_TYPE for your resource. More information
* http://opennebula.org/doc/4.2/oca/ruby/OpenNebula/Document.html
* http://opennebula.org/doc/4.2/oca/ruby/OpenNebula/DocumentPool.html
and the DocumentJson subclass that uses this class to store JSON objects:
* http://opennebula.org/doc/4.2/oca/ruby/OpenNebula/DocumentJSON.html
*
http://opennebula.org/doc/4.2/oca/ruby/OpenNebula/DocumentPoolJSON.html
You can see an example on how to use these classes in the ServiceTemplate
and ServiceTemplatePool classes of OneFlow:
*
https://github.com/OpenNebula/one/blob/master/src/flow/lib/models/service_template.rb
* Instead of modifying the SunstoneServer.rb, you can use the Sunstone
server plugins to add custom routes to the server:
*
http://opennebula.org/documentation:rel4.2:sunstone_server_plugin_guide
*
https://github.com/OpenNebula/one/blob/master/src/sunstone/routes/oneflow.rb
* And the last one, instead of modifying the opennebula.js file you can
include those calls in your vclusters-tab.js as we did with
oneflow-service.js
*
https://github.com/OpenNebula/one/blob/master/src/sunstone/public/js/plugins/oneflow-templates.js#L19
Maybe this information is not clear in the documentation, I just wanted to
let you know about these features. This will allow you to integrate this
component without modifying any of the existing OpenNebula files.
If you have any doubts please do not hesitate to ask us.
Cheers
