Set up Multiple Instances of Lighthouse

This section 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.

If you are using an external certificate authority (CA) and it requires manual approval for certificates, a seconday enrollment cannot complete until the manual approval is done. This must be done within one hour.
