Assigning Node Status During Cluster Creation

This page explains how ShipOps assigns system-node status when a cluster is created for the first time.

Assignment Rule​

The number of system nodes is always odd. System status is assigned only when the cluster is created, according to the following rule:

  • If the total number of nodes is odd, all nodes become system nodes.
  • If the total number of nodes is even, all nodes except the last one in the list become system nodes. The last node remains a regular, non-system node.

Why This Matters​

This rule helps ShipOps preserve the expected control-plane layout during initial cluster creation. For related planning guidance, see How Many Servers to Use for a Cluster and Cluster.
