How to Install Keptn on Kubernetes Cluster?

In the ever-evolving landscape of cloud-native applications, orchestrating and managing microservices efficiently has become a crucial aspect. Keptn, an open-source framework, simplifies the deployment and operation of cloud-native applications on Kubernetes. In this guide, we will walk you through the step-by-step process of installing Keptn on a Kubernetes cluster, empowering you to streamline your DevOps practices.

1. Prerequisites:
   Before diving into the installation process, ensure that you have the following prerequisites in place:

   • A running Kubernetes cluster
   • kubectl command-line tool installed
   • Helm v3

2. Installing Keptn CLI:
   To begin, you need to install the Keptn command-line interface (CLI) on your local machine. Open a terminal and run the following command:

   curl -sL https://get.keptn.sh | sudo -E bash
   

3. Setting Up Keptn on Kubernetes:
   With the Keptn CLI installed, it's time to set up Keptn on your Kubernetes cluster. Execute the following commands to deploy Keptn components:

   keptn install --platform=kubernetes
   

4. Verifying Installation:
   Confirm that Keptn is successfully installed by checking the status of the Keptn core services. Run the following command:

   kubectl get pods -n keptn
   

5. Exposing Keptn Bridge:
   To access the Keptn Bridge, a web-based user interface, expose it using the following command:

   kubectl -n keptn port-forward service/bridge --address 0.0.0.0 8080:8080
   

6. Accessing Keptn Bridge:
   Open your web browser and navigate to http://localhost:8080 to access the Keptn Bridge. Here, you can monitor your projects, services, and automate your delivery pipelines.

7. Creating a Sample Project:
   Let's create a sample project in Keptn to understand how it works. Execute the following command:

   keptn create project myproject
   

8. Onboarding a Service:
   After creating a project, onboard a service by running the following command:

   keptn onboard service myservicename --project=myproject --chart=public/keptn-sample-service
   

9. Triggering a Deployment:
   To trigger a deployment for the onboarded service, use the following command:

   keptn trigger delivery --project=myproject --service=myservicename --image=yourdockerhub/yourimage --tag=latest
   

10. Viewing Deployment Results:
    Check the deployment status and results on the Keptn Bridge or by using the CLI:

    keptn get event evaluation-done --project=myproject --service=myservicename
    

11. Cleaning Up:
    If needed, you can uninstall Keptn from your Kubernetes cluster using the following command:

    keptn uninstall
