Kong Gateway Operator

Kong Gateway Operator is a Kubernetes Operator that can manage your Kong Ingress Controller, Kong Gateway Data Planes, or both together when running on Kubernetes.

With Kong Gateway Operator, users can:

• Deploy and configure Kong Gateway services.
• Customise deployments using PodTemplateSpec to:
  • Deploy sidecars,
  • Set image,
  • And much more.
• Upgrade Data Planes using a rolling restart or blue/green deployments.
• Configure auto scaling on Data Planes.

Current Features

The following features are considered supported:

• Kong Gateway Deployment & Configuration Management using the Gateway API
• Creation of Kong Gateways using the DataPlane API
• Kong Gateways upgrades, downgrades and autoscaling
• Creation of Kong Ingress Controller instances using the ControlPlane API
• Hybrid Mode Attachment using the DataPlane API
• Configuration and management of AIGateways (experimental feature)

See our Features Page for details on these capabilities.

API stability

The operator provides 2 APIs:

• YAML / manifests API which users use to apply their manifests against Kubernetes clusters.
• Go API through types exported under api/ and other exported packages.

This project:

• Follows Kubernetes API versioning for the YAML API.
  • This is considered part of the user contract.
• Tries to not break users implementing against operator's Go API but does not offer a non breaking guarantee.

Quick Start and documentation

If you are eager to start with the operator, you can visit the quick start section of the documentation. Alternatively, the complete docs provide a full and detailed description of how to thoroughly use this project.

Development

Prerequisites

In order to build the operator you'll have to have Go installed on your machine. In order to do so, follow the instructions on its websitego-dev-site.

Build process

Building the operator should be as simple as running:

make build

This Makefile target will take care of everything from generating client side code, generating Kubernetes manifests, downloading the dependencies and the tools used in the build process and finally, it will build the binary.

After this step has finished successfully you should see the operator's binary bin/manager.

You can also run it directly via make run which will run the operator on your machine against the cluster that you have configured via your KUBECONFIG.

Adding new CRDs

Whenever you add a new CRD:

• Ensure that it is included in project's PROJECT file. This is necessary for creation of a bundle for external hubs like Operator Hub's community operators.
• Annotate the CRD and any new type it depends on with the right markers to make sure it will be included in the generated documentation. See available markers.
