1. Deploy the tekton helm chart on Opensshift


    To deploy the Tekton Helm chart on an OpenShift cluster using Pulumi, we will primarily utilize the kubernetes.helm.v3.Chart resource from Pulumi's Kubernetes provider. This resource allows us to deploy Helm charts into a Kubernetes cluster managed by OpenShift.

    Before you begin, ensure you have the following prerequisites:

    1. An OpenShift cluster up and running.
    2. Helm chart information for Tekton, which typically includes the chart name and repository URL.
    3. Pulumi CLI installed.
    4. kubectl configured to connect to your OpenShift cluster.

    Below is the Pulumi program written in TypeScript to deploy the Tekton Helm chart into your OpenShift cluster. This program assumes that your Pulumi stack is already configured for the correct Kubernetes context to interact with your OpenShift cluster.

    import * as k8s from "@pulumi/kubernetes"; // Define the Tekton Helm chart. Replace <repo_url> with the repository URL where the Tekton chart is located. const tektonChart = new k8s.helm.v3.Chart("tekton", { chart: "tekton", version: "0.20.1", // specify the version of Tekton chart you want to deploy fetchOpts: { repo: "<repo_url>", // specify the repository URL for Tekton chart }, // Optionally, you can specify the namespace where Tekton should be deployed. // If not specified, it will be deployed to the 'default' namespace. namespace: "tekton-pipelines", // Values can be provided to configure the chart as needed. values: { // Add any specific values you want to override from the Tekton chart values. // For example, you might want to specify a different storage backend or customize resource requests/limits. }, }); // Export the resources so you can easily access them later, for example the Tekton dashboard URL if exposed. export const tektonChartResources = tektonChart.resources;

    This program performs the following actions:

    • It imports the Kubernetes package from Pulumi, which contains the necessary classes and functions to interact with Kubernetes resources.
    • It creates a new instance of the Chart resource, representing the Tekton Helm chart deployment.
      • The chart name (tekton) and the version are specified. You should replace "0.20.1" with the version of the Tekton chart you intend to deploy.
      • The fetchOpts.repo is where you need to provide the URL of the Helm repository that hosts the Tekton chart. The placeholder <repo_url> should be replaced with the actual URL.
      • The namespace option allows you to specify the namespace where Tekton should be deployed. The example uses "tekton-pipelines" as the namespace, but you can change it to a namespace of your choice.
      • The values is a dictionary object where you can provide overrides for the default values in the Tekton Helm chart.

    Finally, the program exports the resources of the Tekton chart. This is useful if you want to reference resources created by the Helm chart in other parts of your Pulumi program.

    To run this program:

    1. Replace <repo_url> with the actual Helm repository URL for Tekton.
    2. Optionally adjust the chart version and namespace to fit your requirements.
    3. You can add any specific values you wish to override in the Tekton Helm chart.
    4. Execute pulumi up in the directory containing this Pulumi program to deploy the Tekton Helm chart to your OpenShift cluster.

    This Pulumi program will use your currently configured Kubernetes context (as seen in kubectl) to deploy resources into your OpenShift cluster. Ensure that your context is set to the OpenShift cluster where you want to deploy Tekton.
