n.jira.plugin.system.issuetabpanels:all-tabpanel ]

Fl=C3=A1vio Ferreira updated KARAF-3609:
-----------------------------------
    Description:=20
I=E2=80=99m using Karaf Cellar 3.0.1 using Hazelcast with network TCP-IP en=
abled instead of Multicast. I=E2=80=99m trying to run immutable application=
s (running inside Docker containers).

To discover Hazelcast Instances in the cluster I=E2=80=99m using cellar-kub=
ernetes feature. However, I tried to use cellar-cloud and the problem is th=
e 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=E2=80=99t 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/BlobStoreDisc=
overyServiceFactory.java] is never called. Therefore, this never happens:

bq. newRegistration =3D bundleContext.registerService(DiscoveryService.clas=
s.getName(), service, (Dictionary) serviceProperties);

I have an exemple to test it, in my github, under this repository: [karaf-c=
ellar-kubernetes-example|https://github.com/FlavioF/karaf-cellar-kubernetes=
-example]

I can=E2=80=99t understand if there is anything that I am missing or if thi=
s is an issue in Service Discovery registry process.

Is there anyone I can chat about this in IRC or any other real time chat?
