[Q] Get info from other Cartridge Group's instance
Setup Stratos for a composition app, etc: Activemq, Wso2ESB
In the ESB, we need the activemq's IP,
In there anyway, we can pass or get this IP via a Macro / Parameter in the
Cartridge definitions?
Thanks

Hi David,
You could use a Metadata API for this purpose. Stratos has one built in [1]
or you could use something like etcd [2].
Once the relevant instance is started a cartridge agent extension/plugin
[3] can publish its IP Address to the Metadata API. Then the dependent
instance can read it using the same approach.

Thanks Mariangela,
But from my purpose, when I define the ESB cartridge, I do not know the
ActivaMQ IP ("*10.100.1.13*"),
{
"name": "payload_parameter.MB_IP",
"value": "*10.100.1.13*"
}
The ESB MB_IP will be created by our Stratos Application deployment. So the
"*10.100.1.13*" should be a macro / payload.

Hi David,
Yah..This is possible..You can use properties section in cartridge
definition to pass any key/value pairs to a cartridge which could be read
by cartridge agent and exported as system properties. Hence you can use
them in cartridge extensions.
Sample key value pair would be as below:
{
"name": "payload_parameter.MB_IP",
"value": "10.100.1.13"
}
@Mari, Can you add this also to the cartridge resource definition section?
It looks like it is missing in the 4.1.0 doc?
Thanks,
Reka
