Security

Which security context should I use with this adaptor ?

Use a context of type "openstack", giving your tenant, your username and your password.

Should I define additional security contexts to access resources (eg. compute nodes) ?

It depends on the type of nodes:

• Compute resource (Nova server): JSaga will automatically add a security context to access the SSHD server on the server. See below for optional arguments "KeypairName" and "PrivateKey"
• Storage resource (Swift container): no additional security needed
• Network resource (Neurone network): not supported yet

Resource management

What is the URL syntax understood by this adaptor ?

The URL must be:

openstack://<HOSTNAME>:<PORT>/v2.0/
Where:
    <HOSTNAME> is the name of the host running the Openstack identity service,
    <PORT> is the port of the Openstack identity service.

Optional arguments:
    KeypairName= the key pair name installed on Openstack
    PrivateKey= the local private key corresponding to the keypair
    
KeypairName and PrivateKey allow to access compute resources with a public key. Otherwise, access will be done
with the password provided by Openstack when the compute resource was booted.

Execution management on compute resources

How can I have the list of available templates for compute resources ?

        ResourceManager rm = ResourceFactory.createResourceManager(session, url);
        rm.listTemplates(Type.COMPUTE);

Data management on storage resources

How do I describe the type of storage node I want to acquire ?

Neither SAGA attributes are supported yet.
