FAQ and Limitations

Frequently Asked Questions

  • Does Elasticsearch discover automatically other ES nodes? No. Multicast is disabled. All hosts (IP+port) must be listed.

  • Can different nodes run on the same machine? Yes but the best is to have 5 machines to be really resilient to failures

  • Do the members of a cluster can be discovered automatically? No, all nodes must be configured in sonar.properties

Limitations

  • A downtime of the cluster has to be accepted when performing SonarQube upgrade or plugins installations

  • There is no way to perform actions on the cluster from a central app - all operations have to be done manually on each node of the cluster

  • All application nodes must be stopped when installing, uninstalling or upgrading a plugin

  • Plugins are not shared, it means if you install/uninstall/upgrade a given plugin in one application node, you need to do the same actions on the other application node
