1. Deploy the cloudflare-tunnel-ingress-controller helm chart on Kubernetes


    To deploy the cloudflare-tunnel-ingress-controller Helm chart on a Kubernetes cluster using Pulumi, you may utilize the Pulumi Kubernetes provider. The Kubernetes provider allows you to interact with your Kubernetes cluster's resources using Pulumi's infrastructure-as-code approach.

    In this case, you will use the Chart resource from the Kubernetes provider, which enables you to deploy a Helm chart. Helm is a package manager for Kubernetes that allows you to package, configure, and deploy applications and services onto Kubernetes clusters.

    Here is a step-by-step program written in TypeScript that demonstrates how to deploy the cloudflare-tunnel-ingress-controller Helm chart:

    1. Import Necessary Libraries: First, you need to import the Pulumi Kubernetes library into your TypeScript program.

    2. Create a Kubernetes Chart Resource: You will then create an instance of the Chart resource. You provide it with a name (cloudflare-tunnel-ingress-controller in this case), and chart details such as the repository where the chart is located, the name of the chart, and the version. If this Helm chart requires additional configuration, you can provide a values object with the configuration parameters.

    3. Run the Pulumi Program: To apply the Pulumi program to your Kubernetes cluster, you run pulumi up. Pulumi will reach out to the Kubernetes cluster configured in your Pulumi stack, and will deploy the Helm chart as specified.

    Now, let's write your Pulumi TypeScript code block:

    import * as k8s from "@pulumi/kubernetes"; // Create an instance of the Helm Chart for the cloudflare-tunnel-ingress-controller. // `chart` corresponds to the chart name in the Helm repository. // Specify the version of the chart you wish to deploy. // `values` field is an object where you can override any of the default chart values. const cloudflareTunnelChart = new k8s.helm.v3.Chart("cloudflare-tunnel-ingress-controller", { chart: "cloudflare-tunnel-ingress-controller", version: "0.1.0", // replace with the actual chart version you want to deploy fetchOpts: { repo: "https://example.com/charts", // replace with the actual Helm repository URL }, // Uncomment and populate the `values` field if you need to pass specific configurations to the Helm chart. // values: { // key: "value", // // additional configuration here // }, }); // Export any necessary information, such as a service endpoint. // This is a placeholder and should be replaced with actual values you want to export. export const endpoint = cloudflareTunnelChart.getResourceProperty("v1/Service", "my-service", "status") .apply(status => status.loadBalancer.ingress[0].ip);

    In the above code:

    • We import the Pulumi Kubernetes package to interact with Kubernetes resources.
    • We create a new Helm chart using new k8s.helm.v3.Chart. This allows us to install the cloudflare-tunnel-ingress-controller Helm chart onto our Kubernetes cluster.
    • We specify the chart name, and optionally, a specific version. You must replace 0.1.0 with the version of the chart you want to use, as well as replacing https://example.com/charts with the actual repository URL of the Helm chart.
    • We comment out the values field, but you can uncomment and set any necessary Helm values that you need to customize.
    • Lastly, we export the service endpoint IP (as an example), which would allow external access to the services managed by this Helm chart. This is a placeholder and typically needs to be customized based on your actual resource names and desired exported properties.

    To apply this Pulumi program, ensure your Pulumi CLI is configured with access to your Kubernetes cluster and then execute pulumi up within the directory of your Pulumi project. This will trigger the deployment of the chart to your cluster.

    Keep in mind that the specifics of the chart name, version, repository URL, and any custom configuration (values) will depend on the cloudflare-tunnel-ingress-controller chart and should be set according to the chart's documentation and your specific requirements.
