1. Deploy the zipkin-gcp helm chart on Opensshift


    To deploy the Zipkin GCP Helm chart on an OpenShift cluster using Pulumi, you need to set up a few prerequisites:

    1. An OpenShift cluster where you have administrative privileges.
    2. Helm and Pulumi installed on your machine.
    3. The Helm chart details for Zipkin GCP, and potentially any custom values you want to overwrite in the default chart configuration.

    You would typically start by configuring your Pulumi environment to use the Kubernetes provider for OpenShift. This can be done by setting up the kubeconfig file to point to your OpenShift cluster.

    Subsequently, you use Pulumi's Chart resource to deploy the Helm chart. The Chart resource from the @pulumi/kubernetes package is designed to work with Helm charts. You would specify the chart name (zipkin-gcp), and the repository where the chart can be found. If you have a values file or specific custom settings you want to apply to the chart, you can specify these in the values property as a JavaScript object.

    I’ll now show you a Pulumi typescript program that deploys the Zipkin GCP Helm chart on an OpenShift cluster. Please ensure you've already logged into your cluster and have Helm available in your local environment.

    import * as k8s from "@pulumi/kubernetes"; // Initialize a Kubernetes provider configured for OpenShift const openshiftProvider = new k8s.Provider("openshift", { kubeconfig: "<YOUR_KUBECONFIG_CONTENT>", // replace with your kubeconfig content or a path to the kubeconfig file }); // Deploy Zipkin GCP using Helm Chart const zipkinGcpChart = new k8s.helm.v3.Chart("zipkin-gcp", { chart: "zipkin-gcp", // The name of the chart version: "x.y.z", // Specify the chart version you want to deploy namespace: "zipkin", // Specify the namespace where you want to deploy. You might need to create this namespace. fetchOpts: { repo: "http://storage.googleapis.com/zipkin-helm", // The Helm chart repository containing zipkin-gcp }, // If you have any specific configurations you want to overwrite, specify them here as an object. // For instance: // values: { // backend: { // type: "gcp", // }, // ... // } }, { provider: openshiftProvider }); // make sure to pass the OpenShift provider // Export the base URL for the Zipkin GCP so that we can easily access it export const zipkinGcpBaseUrl = zipkinGcpChart.getResourceProperty("v1/Service", "zipkin-gcp", "status").apply(status => status.loadBalancer.ingress[0].hostname);

    Explanation of the code:

    1. We import the Pulumi Kubernetes library which allows us to interact with Kubernetes resources.
    2. A Kubernetes provider is instantiated, configured to connect to your OpenShift cluster using the kubeconfig information.
    3. We create a Chart resource, which is Pulumi's representation of a Helm chart deployment.
    4. The chart key specifies the name of the Helm chart we want to deploy – in this case, zipkin-gcp.
    5. The version key specifies the version of the Chart. Replace x.y.z with the actual chart version.
    6. We set the namespace where the chart should be deployed. Ensure that this namespace is already created on your cluster or add a step to create it.
    7. The fetchOpts defines the Helm repository containing the Zipkin GCP chart.
    8. We pass the openshiftProvider to make sure Pulumi uses the correct Kubernetes context that points to our OpenShift cluster.
    9. Optionally, under the values key, we can configure custom values for our Helm chart deployment. This is not illustrated above but can be tailored to your specific needs.
    10. An export statement allows us to output the ingress host of the deployed service, making it accessible.

    Make sure to replace placeholder <YOUR_KUBECONFIG_CONTENT> with the actual kubeconfig contents or set it up as per OpenShift's authentication mechanisms which might involve tokens or other OpenShift specific authentication configurations.

    Keep in mind that working with cloud resources requires appropriate permissions, and you may need to adjust your user permissions or roles in your OpenShift cluster accordingly. Additionally, deploying a Zipkin GCP chart might incur costs if the chart provisions cloud resources, so ensure you understand the cost implications beforehand.
