Hi Matt,
Thank you for your answers. But I still have some questions.
1.
The server node is ok. We could create a VM based on the requirements of the Server node. But in the CSAR package, should we indicate which os (in the demo we will use RHEL6.3) will be installed on the VM ? but this information is not include in the CSAR package except README.
2.Indeed we discuss it several weeks before. I remember that in your opinion that the os already includes with some softwares(apache, mysql etc) (plz see the attachment 1. in the mail, “ it appears that they assume that the operating system (as part of the VM, which is named "VmApache_os" in the "SugarCRM-Defintions.xml" file)
already has the Apache and MySQL software available.
” ) ; but with Thomas opinion, it is just the pure os without any other software. ( plz see the attachment 2. In the mail,
“ On your second question: the statement in my last email is correct:
the VMs just have the base operating system installed and do not yet include any of the packages for mysql. httpd, php etc.
Those get installed by deploying the DeploymentArtifacts of type OsPackageArtifact. This is purely declarative, so that's why there is no install command in any of the scripts. Solely by the fact that those DeploymentArtifacts are defined, the orchestrator "knows" that the respective packages have to be installed before any of the script operations run. Based on the package type, the orchestrator "knows" which install commands to use for the packages. ”) and in the CSAR package, there are some OsPackageArtifact which provide the information about the install package( file type etc.) but without reference which indicate the place to get the install package, for example:
<ArtifactTemplate id="at-ApacheWebServer-http-packages"
name="http-packages" type="ns1: OsPackageArtifac t">
<Properties>
<ns1:OsPackageArtifactProperties
xmlns:ns1="http://docs.oasis-open.org/tosca/ns/2011/12/ToscaBaseTypes"
packageType="rpm " xmlns="http://docs.oasis-open.org/tosca/ns/2011/12/ToscaBaseTypes">
<PackageInformation packageName="httpd"/>
</ns1:OsPackageArtifactProperties>
</Properties>
</ArtifactTemplate>
So which solution we should use?
Any suggestions & comments will be appreciated.
Best Regards

Hi Chin,
Just a reminder that Thomas is on vacation starting this week for 3 weeks so will not likely reply before then.
Let me attempt to answer your questions (and I also asked Derek to comment) just looking at the README (in the latest CSAR file) and the "install.sh" scripts for Apache, MySQL and ApachePHP:
1) The README indicates that the assumed OS image is "Red Hat Enterprise Linux (RHEL) version 6.3 x86_64 base image for the virtual machines".
In regard to "OS" and "Server" nodes:
Server Node
: Each company is assumed to have an ability to allocate a "server" (or a CPU, virtual server or virtual CPU) in their respective cloud. When the "Server" node type is found by the orchestrator, it should allocate such a server and attempt to provide the "properties" requested for a "server" e.g. CPU speed, memory etc. that are set in the Server's Node Template.
OS
Node : Each company is assumed to have a repository of OS images (VMs) available that the orchestrator would use to automatically deploy when an "Operating System" node type was found in the (template) model (in this case RHEL 6.3). With this assumption, there is no need to included deployment artifacts for RHEL in the CSAR,
2) The RHEL 6.3 image is assumed to already have the Apache, MySQL and Apache PHP already installed in the image so that when the orchestrator executes the "install.sh" scripts for these nodes that the BASH files simply use "chkconfig" command to make sure all these are started as "services" when the image itself is started. This is quite a common assumption for clouds as many applications assume a LAMPs (Linux, Apache, MySQL, PHP) stack to run so it makes sense that most cloud providers have "ready made" images with these software components already installed.
>>> for example, Apache ("httpd" service) when the orchestrator installs the node type "ApacheWebServer" it finds the BASH script "scripts/ApacheWebServer/install.sh" script which simply has the single line "chkconfig httpd on". This assumes the "httpd" RPM packages are already installed on the RHEL 6.3 image. There are similar assumptions for both the MySQL and ApachePHP software packages.
Lastly, we agreed in creating the CSAR for SugarCRM to use only open source software packages to avoid licensing issues. IBM will not be able to legally redistribute any open source package so we cannot send you the Apache, MySQL, etc. that we have.
Apache, MySQL and PHP support can easily be downloaded directly from their owner's websites (free) or you can use the RPM package installer with RHEL operating system when creating your "RHEL 6.3" image to install them into the image directly.

Kind regards,
Matt

Hi Thomas
Some questions about the CSAR, would you kindly to answer them?
1.There is no image in the csar, and also no deployment artifact for those "OS" and "Server". So, how to ref those image during the deployment?
2.For the components "PhpModule", "ApacheWebServer" and "MySql", there are deployment artifacts in the service template but without ref install files (e.g. tar, rpm...). So, how to deploy those components?
How does IBM solve those problems?
By the way, Would you provide the version of apache, mysql and php which you used for the demo?
Best Regards

Hi Chin,
Thomas is the expert on the CSAR file as he created it, but I will attempt to answer based upon what I know and what I see in the actual SugarCRM CSAR file (ZIP) uploaded to the TOSCA Interop SC here:
https://www.oasis-open.org/apps/org/workgroup/tosca-interop/download.php/47264/SugarCRM-20121022.zip
1. How is the Tosca container connect to the VM instance? Just by ssh, or the other method? If by ssh, what’s the username and password will be used?
It appears that most of the scripts assume that they are being run within the instance itself. In that way, they are able to be run immediately after the VM is created by the orchestration engine.
2. Have the Mysql and Apache already integrated in the VM images and only to config them? Or VM images just provide the pure OS, the Mysql and Apache will be installed through Tosca CSAR file? What is the account name
and password for the mysql? I still suggest to use the same VM images for the demo. It could reduce many problems.
Looking at the scripts, it appears that they assume that the operating system (as part of the VM, which is named "VmApache_os" in the "SugarCRM-Defintions.xml" file) already has the Apache and MySQL software available.
The "install.sh" scripts for Apache ("httpd") and MySQL ("mysqld") both use the "chkconfig" utility to configure and have them "autostart" as services when the VM itself is started. The chkconfig utility is assumed to be present on many Linux distros. and
is commonly used for this purpose.
I would ask Thomas or Derek to describe how userid/passwords are managed in the actual CSAR file we used for interop. For initial development and testing, I would recommend using whatever userid/password you may need (and likely it is the admin password for
the operating system image of the VM).
3. In the discussion, I remember that there is a import and export process. Is it means that the demo will use the company A ‘s tool to generate the CSAR file and use company B ‘s runtime environment to deploy it with
that CSAR file? We worried that the used different CSAR may cause some problems, so we suggest that: The CSAR file generate by the tools should be provide as soon as possible for the other company to test their deploy demo;
Yes, the "story" will be as you have outlined. Using your example, Company A will be Vnomic which will effectively create the ZIP of the CSAR file (in this interop this will be equivalent / completely identical to
the " SugarCRM-20121022.zip " file uploaded to the TOSCA Interop. SC, but it would actually contain the SugarCRM software ZIP file. As in the Pulse demo,
Vnomic would export (or "upload") the ZIP to the IBM ISM Cloud Marketplace where Company B (or Company C, D, etc.) would be able to download it from and "import" it into their tools or deploy to their cloud (runtime).
I hope this helps. Anyone feel free to correct me if I am wrong in any of these answers.
Kind regards,
Matt

Hi all
As Huawei want to show the process of the deployment. It means that the demo will use the CSAR file directly. So there are some questions need to clarify:
1. How is the Tosca container connect to the VM instance? Just by ssh, or the other method? If by ssh, what’s the username and password will be used?
2. Have the Mysql and Apache already integrated in the VM images and only to config them? Or VM images just provide the pure OS, the Mysql and Apache will be installed through Tosca CSAR file? What is the account name and

Hi Jin Qin, the current SugarCRM does not include VM images and also no references to images. Currently, we are assuming that the respective cloud runtime will just provide an RHEL 6.3 x86_64 or equivalent image (Fedore or CentOS) for creating the VMs. On your second question: the statement in my last email is correct: the VMs just have the base operating system installed and do not yet include any of the packages for mysql. httpd, php etc. Those get installed by deploying the DeploymentArtifacts of type OsPackageArtifact. This is purely declarative, so that's why there is no install command in any of the scripts. Solely by the fact that those DeploymentArtifacts are defined, the orchestrator "knows" that the respective packages have to be installed before any of the script operations run. Based on the package type, the orchestrator "knows" which install commands to use for the packages. Regards, Thomas

questions about demo
Hi Thomas,
VM images are supposed to be included in the CSAR package. These VM images should be referenced by the corresponding NodeTemplate or NodeTypeImplementation. But we find no clue in the current CSAR package that can lead to an image. So we just wander how could you locate and import the VM images before deploying the CRM application?
In the last email which you reply to me mentioned that the VM image just provide the base operation system. But in Matt’s mail, he said the VM image should include the Apache or Mysql. So could you discuss with Matt to ensure which solution IBM will adopt? Indeed I prefer Matt’s opinion, it could make the test more simply. And currently the scripts are not provide the install function. Best Regards Jin Qin HUAWEI TECHNOLOGIES CO.,LTD. (Embedded image moved to file: pic14506.jpg)huawei_logo
