Bring Your Own Kubernetes

The Bring Your Own Kubernetes (BYOK) offering allows you to take a Kubernetes cluster and plug it into the Control Plane Cloud Platform. It works by installing a few additional components into the cluster and then it registers as a new Location in the API for your Org(s). Any Workloads that are configured for that Location will be managed by Control Plane and roll out onto your cluster. You get all the benefits of Control Plane with the added flexibility and security of running in your own cloud account or data center.

Setup Procedure

To begin the setup process, please contact customer support on your slack channel. They will need a few details in order to build a setup package for your cluster.

  • Cloud Provider or Datacenter Location
  • Orgs the cluster will be allowed to use this Location
  • Location Name
