Datacenters

Overview

There are 2 types of datacenters:

  • Seed datacenter, where Kubermatic Kubernetes Platform’s (KKP) controller-manager and the control planes for each customer cluster are running.
  • Node datacenter, where the customer worker nodes are provisioned.

Both are defined in a file named datacenters.yaml:
