1. Deploy the tyk-gateway helm chart on Opensshift


    To deploy the tyk-gateway Helm chart on an OpenShift cluster using Pulumi, you would typically perform the following steps:

    1. Setup Pulumi OpenShift or Kubernetes Provider:

      • OpenShift clusters can be interacted with using the standard Kubernetes API, and hence you can use either the Pulumi Kubernetes provider directly or set up an OpenShift-specific provider if available. There is no special provider for OpenShift in Pulumi right now, so we’ll use the Kubernetes provider.
    2. Create a Chart Resource:

      • The helm.sh/v3.Chart resource from the @pulumi/kubernetes package is used to deploy helm charts. This resource can apply a Helm chart from the repository to the cluster.
    3. Configure Chart Values If Necessary:

      • If custom configurations are needed, specify them using the values parameter of the Chart resource.

    Here's the code in TypeScript that performs the deployment:

    import * as kubernetes from "@pulumi/kubernetes"; // Define the settings for the Helm chart, such as the chart name, version, and any custom values const tykGatewayChart = new kubernetes.helm.v3.Chart("tyk-gateway", { // Replace with the actual repo URL for tyk-gateway Helm chart // Assuming Tyk offers a Helm repository; otherwise, you'll need to use a URL directly repo: "tyk-helm", chart: "tyk-gateway", version: "x.y.z", // Replace with the actual chart version you want to deploy. // Specify custom values for the chart as needed values: { // ... specify your custom values here, if necessary }, // It’s important to provide the namespace if you’re deploying to a specific namespace. namespace: "tyk", },{ // If you have multiple clusters or a kubeconfig for the specific OpenShift cluster, you can set the provider explicitly. // Example provider configuration: // provider: openshiftProvider // Specify your configured OpenShift provider }); // Export any needed resources export const tykGatewayChartName = tykGatewayChart.metadata.name;

    Explanation of the code:

    • We import the @pulumi/kubernetes package, which provides the resources to interact with Kubernetes (and by extension, OpenShift).
    • We create a helm.v3.Chart resource, which is used to deploy a Helm chart in our OpenShift cluster. You would need to replace 'tyk-helm' with the correct repository URL for the Tyk Gateway Helm chart and the version 'x.y.z' with the version of the chart you intend to deploy.
    • The values object is used to customize the Helm chart. You may include any Tyk Gateway configuration specific to your needs here. If no custom values are necessary, this can be omitted.
    • The namespace parameter is where you specify the namespace into which the chart should be deployed. Replace 'tyk' with the namespace you are targeting.
    • The comment regarding the provider configuration is important if you need to explicitly set a provider. This is common when working with multiple clusters or specific kubeconfig contexts.

    Please note that in a real-world scenario, you will have to confirm the exact parameters and configurations required by the Tyk Gateway Helm chart, and adjust the values accordingly.

    Also, before running this Pulumi program, ensure you have access to the OpenShift cluster and that your kubeconfig is set up correctly to allow Pulumi to communicate with your cluster. The Pulumi CLI and required packages should also be installed in your development environment.

    Remember, this code assumes that the Helm chart is already available in a repository and that you have proper access to deploy to your OpenShift cluster. If you're running this in an environment where the kubeconfig is not set up, you would need to instantiate and configure a Kubernetes provider with appropriate credentials.
