Introducing ingress2gateway; Simplifying Upgrades to Gateway API Wednesday, October 25, 2023 Authors: Lior Lieberman (Google), Kobi Levi (independent) Today we are releasing ingress2gateway, a tool that can help you migrate from Ingress to Gateway API. Gateway API is just weeks away from graduating to GA, if you haven't upgraded yet, now's the time to think about it! Background In the ever-evolving world of Kubernetes, networking plays a pivotal role. As more applications are deployed in Kubernetes clusters, effective exposure of these services to clients becomes a critical concern. If you've been working with Kubernetes, you're likely familiar with the Ingress API, which has been the go-to solution for managing external access to services. The Ingress API provides a way to route external traffic to your applications within the cluster, making it an indispensable tool for many Kubernetes users. Ingress has its limitations however, and as applications become more complex and the demands on your Kubernetes clusters increase, these limitations can become bottlenecks. Some of the limitations are: * Insufficient common denominator - by attempting to establish a common denominator for various HTTP proxies, Ingress can only accommodate basic HTTP routing, forcing more features of contemporary proxies like traffic splitting and header matching into provider-specific, non-transferable annotations. * Inadequate permission model - Ingress spec configures both infrastructure and application configuration in one object. With Ingress, the cluster operator and application developer operate on the same Ingress object without being aware of each other's roles. This creates an insufficient role-based access control and has high potential for setup errors. * Lack of protocol diversity - Ingress primarily focuses on HTTP(S) routing and does not provide native support for other protocols, such as TCP, UDP and gRPC. This limitation makes it less suitable for handling non-HTTP workloads. Gateway API To overcome this, Gateway API is designed to provide a more flexible, extensible, and powerful way to manage traffic to your services. Gateway API is just weeks away from a GA (General Availability) release. It provides a standard Kubernetes API for ingress traffic control. It offers extended functionality, improved customization, and greater flexibility. By focusing on modular and expressive API resources, Gateway API makes it possible to describe a wider array of routing configurations and models. The transition from Ingress API to Gateway API in Kubernetes is driven by advantages and advanced functionalities that Gateway API offers, with its foundation built on four core principles: a role-oriented approach, portability, expressiveness and extensibility. A role-oriented approach Gateway API employs a role-oriented approach that aligns with the conventional roles within organizations involved in configuring Kubernetes service networking. This approach enables infrastructure engineers, cluster operators, and application developers to collectively address different aspects of Gateway API. For instance, infrastructure engineers play a pivotal role in deploying GatewayClasses, cluster-scoped resources that act as templates to explicitly define behavior for Gateways derived from them, laying the groundwork for robust service networking. Subsequently, cluster operators utilize these GatewayClasses to deploy gateways. A Gateway in Kubernetes' Gateway API defines how external traffic can be directed to Services within the cluster, essentially bridging non-Kubernetes sources to Kubernetes-aware destinations. It represents a request for a load balancer configuration aligned with a GatewayClass' specification. The Gateway spec may not be exhaustive as some details can be supplied by the GatewayClass controller, ensuring portability. Additionally, a Gateway can be linked to multiple Route references to channel specific traffic subsets to designated services. Lastly, application developers configure route resources (such as HTTPRoutes), to manage configuration (e.g. timeouts, request matching /filter) and Service composition (e.g. path routing to backends) Route resources define protocol-specific rules for mapping requests from a Gateway to Kubernetes Services. HTTPRoute is for multiplexing HTTP or terminated HTTPS connections. It's intended for use in cases where you want to inspect the HTTP stream and use HTTP request data for either routing or modification, for example using HTTP Headers for routing, or modifying them in-flight. Diagram showing the key resources that make up Gateway API and how they relate to each other. The resources shown are GatewayClass, Gateway, and HTTPRoute; the Service API is also shown Portability With more than 20 API implementations, Gateway API is designed to be more portable across different implementations, clusters and environments. It helps reduce Ingress' reliance on non-portable, provider-specific annotations, making your configurations more consistent and easier to manage across multiple clusters. Gateway API commits to supporting the 5 latest Kubernetes minor versions. That means that Gateway API currently supports Kubernetes 1.24+. Expressiveness Gateway API provides standard, Kubernetes-backed support for a wide range of features, such as header-based matching, traffic splitting, weight-based routing, request mirroring and more. With Ingress, these features need custom provider-specific annotations. Extensibility Gateway API is designed with extensibility as a core feature. Rather than enforcing a one-size-fits-all model, it offers the flexibility to link custom resources at multiple layers within the API's framework. This layered approach to customization ensures that users can tailor configurations to their specific needs without overwhelming the main structure. By doing so, Gateway API facilitates more granular and context-sensitive adjustments, allowing for a fine-tuned balance between standardization and adaptability. This becomes particularly valuable in complex cloud-native environments where specific use cases require nuanced configurations. A critical difference is that Gateway API has a much broader base set of features and a standard pattern for extensions that can be more expressive than annotations were on Ingress. Upgrading to Gateway Migrating from Ingress to Gateway API may seem intimidating, but luckily Kubernetes just released a tool to simplify the process. ingress2gateway assists in the migration by converting your existing Ingress resources into Gateway API resources. Here is how you can get started with Gateway API and using ingress2gateway: 1. Install a Gateway controller OR install the Gateway API CRDs manually . 2. Install ingress2gateway. If you have a Go development environment locally, you can install ingress2gateway with: go install github.com/kubernetes-sigs/ingress2gateway@v0.1.0 This installs ingress2gateway to $(go env GOPATH)/bin/ ingress2gateway. Alternatively, follow the installation guide here. 3. Once the tool is installed, you can use it to convert the ingress resources in your cluster to Gateway API resources. ingress2gateway print This above command will: 1. Load your current Kubernetes client config including the active context, namespace and authentication details. 2. Search for ingresses and provider-specific resources in that namespace. 3. Convert them to Gateway API resources (Currently only Gateways and HTTPRoutes). For other options you can run the tool with -h, or refer to https://github.com/kubernetes-sigs/ ingress2gateway#options. 4. Review the converted Gateway API resources, validate them, and then apply them to your cluster. 5. Send test requests to your Gateway to check that it is working. You could get your gateway address using kubectl get gateway -n -o jsonpath='{.status.addresses}{"\ n"}'. 6. Update your DNS to point to the new Gateway. 7. Once you've confirmed that no more traffic is going through your Ingress configuration, you can safely delete it. Wrapping up Achieving reliable, scalable and extensible networking has always been a challenging objective. The Gateway API is designed to improve the current Kubernetes networking standards like ingress and reduce the need for implementation specific annotations and CRDs. It is a Kubernetes standard API, consistent across different platforms and implementations and most importantly it is future proof. Gateway API is the next generation of the Ingress API, but has a larger scope than that, expanding to tackle mesh and layer 4 routing as well. Gateway API and ingress2gateway are supported by a dedicated team under SIG Network that actively work on it and manage the ecosystem. It is also likely to receive more updates and community support. The Road Ahead ingress2gateway is just getting started. We're planning to onboard more providers, introduce support for more types of Gateway API routes, and make sure everything syncs up smoothly with the ongoing development of Gateway API. Excitingly, Gateway API is also making significant strides. While v1.0 is about to launching, there's still a lot of work ahead. This release incorporates many new experimental features, with additional functionalities currently in the early stages of planning and development. If you're interested in helping to contribute, we would love to have you! Please check out the community page which includes links to the Slack channel and community meetings. We look forward to seeing you!!
