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 | 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 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
