Once you have created your cluster groups and assigned nodes to the different cluster groups, you can target the deployment of the resources on a given cluster group. For this, Cellar provides the cluster-aware commands of the regular Karaf commands.
For instance, Karaf provides a features:install <feature_name> command to install a Karaf feature in the container. Additionally, Cellar provides cluster:feature-install <group_name> <feature_name>, which is similar to the features:install command. The features:install command will install the feature locally to the Karaf container, whereas the cluster:feature-install command will install the feature on the cluster in the given cluster group.
At the end of this chapter, you will find a table that introduces Cellar's cluster:* commands which correspond to the regular Karaf commands.
