Announcing F5 NGINX Gateway Fabric 1.3.0 with Tracing, GRPCRoute, and Client Settings
The release of NGINX Gateway Fabric version 1.3.0, introduces plenty of highly requested features and improvements. GRPCRoutes are now supported to manage gRPC traffic, similar to the handling of HTTPRoute. The update includes new custom policies like ClientSettingsPolicy for client request configurations and ObservabilityPolicy for enabling application tracing with OpenTelemetry support. The GRPCRoute allows for efficient routing, header modifications, traffic weighting, and error conversion from HTTP to gRPC. We will explain how to set up NGINX Gateway Fabric to manage gRPC traffic using a Gateway and a GRPCRoute, providing a detailed example of the setup. It also outlines how to enable tracing through the NginxProxy resource and ObservabilityPolicy, emphasizing a selective approach to tracing to avoid data overload. Additionally, the ClientSettingsPolicy allows for the customization of NGINX directives at the Gateway or Route level, giving users control over certain NGINX behaviors with the possibility of overriding Gateway defaults at the Route level. Looking ahead, the NGINX Gateway Fabric team plans to work on TLS Passthrough, IPv6, and improvements to the testing suite, while preparing for larger updates like NGINX directive customization and separation of data and control planes.

We announced the next release of F5 NGINX Gateway Fabric version 1.4.0 which includes a lot of smaller but very necessary features. This allows us to dedicate more time to advancing our non-functional testing framework and ensuring we maintain top performance across releases. Nevertheless, we have some great highlights of this release: IPv6 support TLS passthrough (via TLSRoute) Server zone metrics Ability to add custom pod annotations Plenty of bug fixes! During this release cycle, we discovered a bug around our custom policies that occurred when you had the same path for more than one Route: The policy would not be applied to either Route. For this release, we’ve decided to enforce a restriction so that policies cannot be applied when two or more routes share the same path. However, we are pursuing a long-term solution to lift this restriction on this edge case, as we understand that use cases that route based on header, query parameter, or other request attributes on the same path do exist. IPv6 Support While most Kubernetes clusters are still utilizing IPv4, we recognized that anyone employing a IPv6 cluster would have no ability to deploy NGINX Gateway Fabric. Thus, we implemented a simple feature to dual IPv4/IPv6 networking for NGINX Gateway Fabric. This option is enabled by default, so you can simply install as normal on an IPv6 cluster. TLS Passthrough New with 1.4 is TLSRoute support. This Route type enables the TLS Passthrough use case and is similar to setting up an HTTPRoute. This allows you to pass encrypted traffic through NGINX Gateway Fabric where it is terminated by your backend application, ensuring end-to-end encryption. As most information passes through NGINX Gateway Fabric with this route, setup is easy. You can enable TLS passthrough for any application using our guide available here. Non-Functional Testing This release marks the completion of automating our non-functional testing that we execute before each release. If you are unfamiliar with these tests, our team runs NGINX Gateway Fabric through a series of scenarios, non-functional tests, to test if our performance is regressing or improving from previous releases. As an infrastructure product that you rely on, it is our top priority to ensure that stability and performance are not compromised as new features are released. The results of all non-functional testing are available in the GitHub repository for anyone to see and should give you an idea of how well NGINX Gateway Fabric performs in general and across releases. What’s Next NGINX Gateway Fabric 1.5.0 will bring NGINX code snippets to the Gateway API with a first-class Upstream Settings policy to configure keepalive connections and NGINX zone size. If you are familiar with NGINX or find that you need to use a feature that NGINX provides that is not yet available via a Gateway API extension, you can put a NGINX code snippet within a SnippetFilter to apply NGINX configuration to a Route rule. You will even be able to use the feature to load other modules NGINX provides and leverage the vast wealth of NGINX functionality. We will still be providing many NGINX features via first-class policies and filters, such as the Upstream Settings policy, as they allow us to handle much of the complexity of translating to Gateway API for you. These custom policies and filters allow us to handle a lot of the complexity of applying NGINX config across the Gateway API framework for you. The Upstream Settings policy can set upstream management directives that are unable to be applied via snippets effectively. We will continue to deliver these custom policies and filters across all of our releases, in addition to new Gateway API resources and NGINX Gateway Fabric specific features. You can see a preview of the full snippet design here, though not all features may be implemented in one release cycle. For more information on our strategy towards first-class NGINX customization via Gateway API extensions, see our full enhancement proposalhere.
