Hybrid Deployments

Kong Gateway Operator deploys and manages DataPlane resources that connect to a externally managed Control Plane using a Hybrid Mode deployment.

The external control plane may be a Kong Konnect control plane, or a self-managed control plane.

Installation

Konnect

Self Managed

# Ensure that you create a secret containing your cluster certificate before applying this
# kubectl create secret tls konnect-client-tls -n kong --cert=./tls.crt --key=./tls.key
