Re: [tosca-interop] Some questions about the SugarCRM ServiceTemplate

[Thomas Spatzier <thomas.spatzier@de.ibm.com>]

Hi Paul,

some answers to your questions:

re 1) Right, no DeploymentArtifact so far. We are using a default image in
our prototype which is RHEL 5.7 x86_64. We will have to define a
DeploymentArtifact for the interop work.

re 2) Actually, I see some alternatives here: we could either point to a
concrete image (a disk image), or rather specify metadata (like desired OS,
version, arch, etc.) and each implementation selects such an image using
its favorite hypervisor. I would prefer this latter option.

re 3) My view: things like getting IP addresses etc. is implementation
specific, this is nothing the application cares about. From an application
point of view, the importing things is that it gets VMs, and that those VMs
have IP addresses - but not how it gets the IP addresses. So each TOSCA
implementation could do this using its own specific mechanisms.

re 4) We will have to define a set of base DeploymentArtifact Types known
to each implementation. Like in our prototype, we "just understand" a
package artifact and know how to deploy it. There is no special operation
required. Deployment of DeploymentArtifacts happens before any operation is
invoked. ... again, a lot of currently undocumented conventions we will
have to work on in the SC.

Thomas

Hi, guys

  I have some questions about the SugarCRM ServiceTemplate:

1.       The VirtualMachine NodeType does not contain a DeploymentArtifact.
So, the image of the virtual machine is not clear.
2.        What  is  the image type of virtual machine? Vmdk or xva, or some
others?  As  the ServiceTemplate is for all involved companies, I think the
xva for Xen (open source) is a good choice.
3.        What  is  the details about the image? For example, how to obtain
the  VM IP address? DHCP or static IP setting? As these details are related
to the implementation, I suggest clarifying them.
4.        In  the  MySql  NodeType,  a  DeploymentArtifact is defined which
refers   a   ArtifactTempalte   defining   two   “PackageInformation”  (RPM
information). However, which operations are used to install these RPMs? The
“install.sh” does not contain the corresponding programs.
