Hi Dinesh,

Thanks for the reply. <= br>
As far as I understand puppet master will identify the node ba= sed on the cert name of the puppet agent. In the case of a generic base ima= ge, does puppet agent pass any additional parameters when communicating wit= h the puppet master to request the node catalogue?

Hi,

When creating a cartridge we set up the base image = by specifying the stratos service name and installing the packages needed f= or that service using puppet. For example if we specify "php" as = the service name PHP packages and its dependencies will be installed.
If we used "default" as= service name it will install cartridge agent, java and basic dependencies.= So base cartridge is not bound to any service type. it is a generic one.

When a new instance is created from a PHP cartridge init.sh is ru= n at the start. This also triggers the puppet agent.=C2=A0

Yes.
=C2=A0
What is the purpose of triggering puppet agent = at instance start up? Is it only to find any manifest updates?
If use a generic cartridge image as &quo= t;imageId" when deploying, puppet agent will install required packages= and dependencies. If use a service bound cartridge image (PHP, MySQL, etc.= ), it will not update any packages or dependencies but update the manifest = updates as you mentioned such as ips and ports of message broker and cep
