1. Deploy the thanos-traefik helm chart on Opensshift


    To deploy the Thanos Traefik Helm chart on an OpenShift cluster using Pulumi, we'll utilize the kubernetes.helm.v3.Chart resource from the Pulumi Kubernetes provider. This resource allows you to deploy Helm charts to a Kubernetes cluster, which in your case is an OpenShift cluster.

    I will guide you through the process and provide you with a TypeScript program that uses Pulumi to deploy the chart. Make sure that you have the necessary prerequisites in place, such as having Pulumi CLI installed, your OpenShift cluster accessible, and having the Kubernetes context pointing to your OpenShift cluster.


    • Helm Chart Resource (kubernetes.helm.v3.Chart): We will be using this Pulumi resource to specify a Helm chart to be deployed. The resource takes several inputs, such as the chart name, repository, version, and any custom values you might need to override.

    • OpenShift: OpenShift is a Kubernetes distribution and thus compatible with Pulumi's Kubernetes provider. So, we will be using Kubernetes resources in the Pulumi program to interact with your OpenShift cluster.

    Below is a comprehensive Pulumi TypeScript program that deploys the Thanos Traefik Helm chart to your OpenShift cluster:

    import * as k8s from "@pulumi/kubernetes"; // Instantiate the Kubernetes provider. // If your OpenShift kubeconfig file is located at a custom path // or if you want to specify a context from your config, you can set the kubeconfig property explicitly. const provider = new k8s.Provider("openshift-provider", { // kubeconfig: "<path-to-your-kubeconfig-file>", // Uncomment and set the path if needed. }); // Create a namespace for your application if it doesn't already exist. const namespace = new k8s.core.v1.Namespace("thanos-traefik-namespace", { metadata: { name: "thanos-traefik" }, }, { provider }); // Deploy the Thanos Traefik Helm chart. const thanosTraefikChart = new k8s.helm.v3.Chart("thanos-traefik-chart", { chart: "traefik", version: "10.3.0", // Specify the precise chart version you wish to deploy. namespace: namespace.metadata.name, fetchOpts: { repo: "https://helm.traefik.io/traefik" }, // Replace with the repository URL of your choice. // If you need to provide custom values, you can include a `values` argument like below: // values: { // // Specify your custom values here. // }, }, { provider }); // Export the application URL by querying the service object and extracting its cluster IP. export const applicationUrl = thanosTraefikChart.getResourceProperty("v1/Service", "thanos-traefik-traefik", "status").apply(status => { // The actual properties to query will depend on how the service is set up in the chart. const ingress = status.loadBalancer.ingress[0]; if (ingress.ip) return `http://${ingress.ip}`; if (ingress.hostname) return `http://${ingress.hostname}`; return null; });

    The above program does the following:

    • Defines a Kubernetes provider to manage resources in the OpenShift cluster.
    • Creates a namespace (if it doesn't already exist) where the Helm chart will be deployed.
    • Deploys the Thanos Traefik Helm chart within the created namespace using the Chart resource.
    • Exports the application URL by looking up the IP or hostname of the load balancer created for Traefik.

    Please note that you should replace version with the actual version of the Thanos Traefik Helm chart you wish to install. Similarly, replace repo with the URL of the Helm repository where the chart is hosted. You might also need to customize the values to match Thanos Traefik's configuration requirements or any custom configurations you would like to apply.

    After you write this Pulumi program in a TypeScript file, you can deploy the Helm chart to Openshift by running pulumi up in your terminal. This command starts the Pulumi deployment process, and you will be prompted to confirm the deployment after a preview of changes is shown.
