GitHub Enterprise clustering requires multiple instances to be set up and configured to run GitHub Enterprise services.
About cluster nodes
Nodes are GitHub Enterprise instances that operate in a cluster. Each node runs a set of services that are provided to the cluster, and ultimately to the users.
Network configuration
GitHub Enterprise clustering relies on proper DNS name resolution, load balancing, and communication between nodes to operate properly.
Initializing the cluster
A GitHub Enterprise cluster must be set up with a license and initialized using the administrative shell (SSH).
