Set up Multiple Instances of Lighthouse

This chapter discusses the licensing, setup, configuration, promoting and disconnecting of secondary instances, and upgrading of a multiple instance Lighthouse.

The multiple instance functionality allows you to set up secondary or dependent instances of Lighthouse that automatically receive updates from a primary Lighthouse instance and maintains connections to all its remote nodes.

Secondary instances are read-only. They may be used to view Lighthouse information specific to that instance using ogconfig-cli, and to connect via pmshell.

Configuration changes must be performed on the primary instance, which then updates the information displayed on the secondary instance.
