Re: [concierge-dev] access Cluster Information Service from distributed OSGi-Nodes
Another option would be to use ECF's implementation of RSA [1].   We have a zookeeper discovery provider...among others [2].   We also have a number of pluggable distribution providers [3].

However, I'm not sure if Concierge currently supports R6 of OSGi framework spec.   ECF supports R7 with it's most recent release (3.14.4), and R7 asynchronous remote services [3] requires OSGi Promises, which are not in R5 frameworks.   So to use OSGi R7 async remote services [4] it's necessary to have an R6 framework impl.     You can use R5 framework impls with ECF RSA, however, as long as you use version 1.x of this bundle [5].

Hey Tim,
 
thanks for your answer. I am using the zookeeper for discovery. The endpoint is provided through the cluster on this way. I can see it in the list of provided endpoints, but i get no service reference for it in my program code. I use the @Reference Annotation for this, but the consumer service stucks after start because no service reference is overgiven.

Hi Jörn,

I myself am not too familiar with the Aries RSA stack, but I think you still need to provide the remote endpoint configuration to the other nodes, e.g. by supplying it through configuration: https://github.com/apache/aries-rsa/tree/master/discovery/config

Best regards,
Tim Verbelen

Hey,
 
i am building a cluster with multiple distributed OSGi-Frameworks. Therefore i use your bundle with the implementation of the Cluster Information Service and for remote access the implementation of the remote service admin service from apache aries. It works to provide and consume different remote custom services in the cluster. Your Eclipse Concierge Cluster Information is also provided with an endpoint, but i cannot access the endpoint via rsa from other nodes. Local access from other bundles in the same node is possible. Do i have to configure anything or something else for remote access?
