Release 0.1.0

August 22, 2022

This is an initial release of NGINX Kubernetes Gateway project.

The release includes:

  • A control plane agent (a Kubernetes controller) that updates date plane (NGINX) configuration based on the state of the resources in the cluster.
  • Support for NGINX as a data plane.
  • Kubernetes manifests for a Deployment with a single Pod with the control plane and data plane containers as well as Services to enable external connectivity to that Pod.
  • Support for a subset of features of GatewayClass, Gateway and HTTPRoute resources (see the Gateway API Compatibility doc).

We expect that the architecture of NGINX Kubernetes Gateway -- the number of pods and containers and their interaction -- will change as the project evolves.

NGINX Kubernetes Gateway is ready for experimental usage. We included the docs as well as examples.

If you'd like to give us feedback or get involved, see the README to learn how.

COMPATIBILITY:

  • The Gateway API version: 0.5.0
  • NGINX version: 1.21.3
  • Kubernetes version: 1.19+
