Install Kaptain on an on-premises cluster

On-Premise Installation

Kaptain natively supports the installation on an on-premise cluster. Before installing Kaptain, please follow the Konvoy On-Premises Installation Guide or Kommander Installation Guide in a networked environment to set up the on-prem cluster. The cluster admin is responsible for configuring the cluster correctly and ensuring the requisite cluster-level applications are enabled.

Please note that the IP address of the Kaptain UI will come from the IP address range that is configured in the MetalLB load balancer.
