---------------------------------------------------
> Kubernetes/Cloud Service Discovery isn't working in Immutable applications
> --------------------------------------------------------------------------
>
> Key: KARAF-3609
> URL: https://issues.apache.org/jira/browse/KARAF-3609
> Project: Karaf
> Issue Type: Bug
> Components: cellar-cloud
> Environment: Karaf Cellar
> Reporter: Flávio Ferreira
> Assignee: Jean-Baptiste Onofré
>
> I’m using Karaf Cellar 3.0.1 using Hazelcast with network TCP-IP enabled
> instead of Multicast. I’m trying to run immutable applications (running
> inside Docker containers).
> To discover Hazelcast Instances in the cluster I’m using cellar-kubernetes
> feature. However, I tried to use cellar-cloud and the problem is the same.
> I belive that, as my applications are immutable and the karaf configuration
> is never updated, the update in Managed Service Factories was never called.
> Thus, the DiscoveryTask can’t find the Karaf Cellar instances in the cluster
> since there are no Service Discovery Implementations registered.
> In short, the update in this
> [class|https://github.com/apache/karaf-cellar/blob/master/cloud/src/main/java/org/apache/karaf/cellar/cloud/BlobStoreDiscoveryServiceFactory.java]
> is never called. Therefore, this never happens:
> bq. newRegistration =
> bundleContext.registerService(DiscoveryService.class.getName(), service,
> (Dictionary) serviceProperties);
> I have an exemple to test it, in my github, under this repository:
> [karaf-cellar-kubernetes-example|https://github.com/FlavioF/karaf-cellar-kubernetes-example]
> I can’t understand if there is anything that I am missing or if this is an
> issue in Service Discovery registry process.
> Is there anyone I can chat about this in IRC or any other real time chat?
