[one-ecosystem] Which cloud interface to choose

[John Samonakis]

Well, I think, now, I use the latest version of OCCI Server (I had
configured incorrectly the server, and the old version was running.)

 

Although I deal with some problems: 

 

When I run getComputes with URI http://ddd.dd.dd.ddd:4567/compute/ 

server respond with code=200 but response.content.length=0 

When I run stopCompute with HttpUtils .post(URI, .)  and URI= http://
ddd.dd.dd.ddd:4567/compute/536?action=stop 

server respond with code=400

When I run deleteCompute with HttpUtils.delete( ID ) and ID= http://
ddd.dd.dd.ddd:4567/compute/536 

server respond with code=404

 

I can't figure out what is going wrong!

 

thanks a lot!

John

Hi John,

 

I'm developing the OCCI 1.1 interface for OpenNebula, see the Wiki at

http://dev.opennebula.org/projects/ogf-occi/wiki/

for more information.

 

You are probably using the old implementation included in OpenNebula based
on the not officially released OCCI 0.8. I can't really help you with that.
If you want to try out the new implementation, just follow the steps in the
Wiki I mentioned above.

 

Cheers,

Florian

Hi!

 

Florian thanks a lot for your valuable info. I have study your
implementation

and I think you have done a very good job! The source code help me 

to understand how to develop my web application.

 

Currently I am trying to list the VMs using the OcciOneListTester but I
receive

the message "Basic auth not provided". 

 

I believe, I have configure correctly the occi service since I can list the
VMs

using the command occi-compute.

 

I use OpenNebula 3.0

 

I search for a solution but the url I found
<http://comments.gmane.org/gmane.comp.distributed.opennebula.user/4323>
http://comments.gmane.org/gmane.comp.distributed.opennebula.user/4323

didn't help me to understand what I have to do.

 

thanks a lot

John

We are currently doing exactly the same using OCCI (for IaaS management) and
CDMI (for storage). I summed it up in a screencast which you may find here:

dl.dropbox.com/u/4837292/OCCI_CDMI_Screencast_large.mp4

 

If that's what you want, you can find the OCCI 1.1 server for OpenNebula
here (please use the latest version from git):

http://dev.opennebula.org/projects/ogf-occi/wiki

 

The CDMI server can be found here:

https://github.com/livenson/vcdm/tree/master/src/vcdm

 

And you can find the Webclient (including a Java library which can be used
stand alone) here:

https://github.com/gwdg/Pollux

 

Especially the client is currently not too well documented, but if you like
to use it, we would be glad to improve documentation and provide support.

 

Cheers,

Florian

Hi

 

I want to make an GUI for educational purposes, in order, students, to use
VM

for their projects. The GUI must have some basic functions such as start,
terminate,

reboot a VM. 

 

There are two cloud interfaces supported: EC2-Query API and OCCI-OGF.

Which of them is more appropriate for my purpose?

 

thanks a lot

John
