Hi Tony, 

After re-readng your question again I tend to agree with Alex. Actions seem to be exactly what you’re asking for.

Hi Tony,  

Thanks for your interest!  

This is a complicated topic. Being able to edit the object model (with  
DynamicUI, the CLI tools mentioned by Kirill or manually with murano's  
API) is just the tip of the iceberg: if you have already deployed your  
application, modifying of some of its input properties will not be  
enough: the application developer has to supply the logic which will  
handle the changes and will execute all the needed actions to  
reconfigure the app.  

Right now the right way to do so is to create an "action" method (see  
[1] for details), which may be called for already deployed apps. In  
this action you may change the properties of the object and do  
whatever custom handling you may need to reconfigure your app. For  
example, if you want to change the password of the database admin user  
of the mysql app, you may add an action method "changeAdminPassword"  
which will not only set '$.password' property to a new value, but will  
also execute an appropriate password-changing script on the VM running  
the database instance.  

Right now the actions are partially supported on the UI level (in the  
dashboard you may call any action of any deployed application),  
however currently you cannot pass any parameters to these actions if  
called from the UI, and being able to pass them is indeed required for  
your scenario (in the aforementioned example with DB password change,  
such an action should have at least one parameter - the new password  
value). This will be probably addressed during the M cycle as part of  
the "per-component UI" initiative mentioned by Kirill: we will provide  
a way to render dynamic UI dialogs not only for the new applications  
being added but also for the actions of the already deployed apps.  

Hope this helps.  
Please let me know if you have any questions on Actions and any other  
related topics
