Integrating Knative with other Kubernetes tools and services

Are you tired of managing your serverless applications on a cumbersome platform? Are you looking for a serverless solution that can integrate seamlessly with other Kubernetes tools and services? If so, Knative is the answer to all your worries!

With Knative, you can manage your serverless applications like never before. In this article, we will talk about how you can integrate Knative with other Kubernetes tools and services to get the most out of your serverless environment.

What is Knative?

Before diving into the integration part, it's essential to understand what Knative is and how it works. Knative is an open-source platform built on Kubernetes, that provides a set of components and tools that allow you to deploy, run, and manage serverless applications. Knative is designed to be lightweight, portable, and extensible, providing a serverless experience on top of Kubernetes.

With Knative, you can build serverless functions, deploy them, and manage them as you would any other Kubernetes application. Knative is built to work with popular container build and deployment tools like Tekton, Kubernetes-native build, and Istio.

Integrating Knative with Kubernetes

Kubernetes is an excellent platform for hosting applications, and using it with Knative can extend its capabilities for serverless functions. With Knative, you can build serverless functions with Kubernetes, all while automated scaling and routing. Kubernetes is the platform that runs Knative's components that let you deploy and manage serverless applications.

In Kubernetes, the resource model (such as Deployments, Pods, and Services) is used to manage applications. Knative provides a serverless abstraction on top of this model, making it easy to deploy serverless applications using Kubernetes’ resources.

To integrate Knative with Kubernetes, the first step is to ensure that Kubernetes is up and running. Once Kubernetes is ready, you need to install Knative components via kubectl apply command to install the Knative Serving component.

kubectl apply --filename

kubectl apply --filename

Integrating Tekton with Knative

Tekton is a Kubernetes-native open-source framework for creating Continuous Integration / Continuous Deployment (CI/CD) systems. Tekton provides a set of building blocks, which include pipelines, tasks, and resources. Tekton integrates seamlessly with Knative, further extending its capabilities.

To integrate Tekton with Knative, you can create a pipeline that deploys your Knative service to your Kubernetes cluster using a trigger. Tekton triggers make it easy to trigger your pipeline when your Knative service is updated or when a new release is deployed.

With Tekton, you can define pipelines that are triggered when Knative services are updated, or there is a new release:

kind: PipelineRun
  name: deploy-my-function
    name: deploy-my-function
    - name: my-function
        type: knative
          - name: service-name
            value: my-function
          - name: image-path

Here, we can see that we are using the PipelineRun resource to specify the deployment of a Knative service. The resource type is set to knative to use the Knative resource type to define the deployment. The params field includes variables that are used in the pipeline, including the image path and service name.

Integrating Istio with Knative

Istio is a popular tool for managing service mesh and is used in conjunction with Knative to provide advanced routing, monitoring, and security features. Istio can be used with Knative to handle traffic routing to Knative services and to implement secure communications using TLS.

To integrate Istio with Knative, you need to ensure Istio is installed in your Kubernetes cluster, and you need to configure Istio to handle traffic to Knative services.

You can use Istio’s routing rules to route traffic to your Knative service. With Istio, you can define routes and apply policies to your Knative services:

kind: RouteRule
  name: my-function
    name: my-function
    namespace: my-namespace
    - labels:
        version: ""
      weight: 100

In this example, we are using Istio’s RouteRule resource to define routing rules to our my-function Knative service.

Integrating Knative with other Kubernetes tools

Integrating Knative with other Kubernetes tools can provide other benefits, including monitoring, security, and observability. Popular Kubernetes tools like Prometheus and Grafana can be used to monitor Knative services and to provide alerts if any issues occur.

To integrate Knative with these tools, you need to configure them to collect metrics from your Knative services:

kind: ServiceMonitor
  name: my-function
    - interval: 2m
      path: /metrics
      port: http

In this example, we are using the ServiceMonitor resource to monitor our my-function service. The endpoints field specifies the metrics endpoint and interval.


Knative is an excellent choice for managing serverless applications on Kubernetes, and integrating it with Kubernetes components can provide many benefits. With Knative and other Kubernetes tools, you can deploy, manage, monitor, and secure your serverless applications with ease.

Integrating Knative with Kubernetes is easy, and with Tekton, Istio, and other Kubernetes tools, you can extend Knative’s capabilities. So, if you are looking for a serverless solution that provides the flexibility and efficiency of Kubernetes, be sure to give Knative a try!
