Hi Daniel,
I have already created templates for cloud users but that does not
allow them, as far as I can see, to make persistent images. In any
event, the freedom to mix and match CPU/Memory/network settings to
various images is lost.
Also, without the ability to create templates I cannot see how they
can create a datablock and install their own images from CD. I can
enable templates in the cloud view but as they are not controlled by
quota I'm worried about not being able to access our sysadmin templates
among an unbounded clutter of user templates. If the user templates
could be stored somewhere else or hidden from view that might solve the
problem.
Using the CLI is not really an option as I had intended to make the
self-service available to undergraduate students. In my experience, even
researchers who had previous cloud experience found the OCCI interface
unintuitive at first. However, once they got the hang of it, it proved
very flexible.
It seems strange to release a new version of software and cripple
functionality that was previously available (Microsoft's Windows 8 come
to mind!). Can OCCI 4.2 be built from source with the UI included or the
version of OCCI shipped with 3.8 pointed at OpenNebula 4.2?
My intention was to deploy 4.2 for student use this week. If I
can't provide the functionality of OCCI 3.8 I will have to abandon 4.2,
which seems a shame.
Regards,
Gerry

Hi Gerry,
As you said the old OCCI-based self-service is deprecated and the ui was
removed from the code. You should be able to use it from the CLI, but it
will be also removed sooner or later.
The current cloud view [1], that was implemented to replace the old
self-service, allows you to select a template and na image and launch a new
instance without creating new templates. The only part missing for you use
case is the network, so maybe we can add this option for upcoming releases,
please open a feature request in our dev page so we can consider it.
Meanwhile you could use the cloud view and create templates that already
define the network (i.e.: small_and_private_net, small_and_public_net,
large_and_private_net ...)
Cheers

Hi,
The reason why I've asked the question below is because I get the
error message below when I try to run the occi-server. I've read in the
posts that it is depreciated but I'm confused as there is documentation
here
http://opennebula.org/**documentation:rel4.2:occiug<http://opennebula.org/documentation:rel4.2:occiug>for
4.2.

Hi,
I'm trying to emulate the ease-of-use of OCCI self-service in
OpenNebula 4.2.0 Sunstone using views. In particular, I liked the idea of
the drop-down list of predefined templates where machines could be
provisioned by adding an image and a network. It seems the only way to
emulate this is to allow cloud users to be able to create templates. While
I appreciate the flexibility of Sunstone views I'm concerned that if cloud
users can create templates then there is a danger that the site will be
littered with templates. If the templates could be placed in another
location that would be great. Is there any way around this or am I missing
something? Somehow, the OCCI self-service was able to hide these templates
that it created on the fly.
Regards,
Gerry
