Re: Karaf Cellar - updating a bundle in cluster
Thank you very much JB! Will it be available after push here: https://github.com/apache/karaf-cellar ? Or it will be other location?

Hi Sergiy, It depends at which level. When the cluster is "live", you can perform cluster:bundle-update / cluster:bundle-install, the event will trigger an update on the nodes.
