1. Deploy the tyk-gateway helm chart on Azure Managed Openshift Service


    To deploy the tyk-gateway Helm chart on Azure Managed OpenShift Service using Pulumi, we'll follow a few steps. This will involve creating an Azure Managed OpenShift Cluster (AMO), and then deploying the Helm chart to it. For simplicity, this example assumes you already have an OpenShift cluster running and have configured your local environment with kubectl and Pulumi.

    Here's how you can achieve this:

    1. Set up Pulumi: You need to have Pulumi installed and set up to work with Azure. You'll also need to be logged in to your Azure account via the Azure CLI (az login).

    2. Create a Managed OpenShift Cluster: You'll need to have a Managed OpenShift cluster on Azure. We will skip this step in the code, but for your reference, you can create one using Azure's portal or CLI, or by using the azure-native.redhatopenshift.OpenShiftCluster resource with Pulumi.

    3. Install Helm: Make sure you have Helm installed on your machine, as we will use the kubernetes.helm.v3.Chart resource that requires Helm for chart deployments.

    4. Pulumi Program: Now let's write a Pulumi program in TypeScript that deploys the tyk-gateway chart using Pulumi's Kubernetes provider.

    Below is the TypeScript program that deploys the Helm chart to your OpenShift cluster:

    import * as k8s from '@pulumi/kubernetes'; import * as pulumi from '@pulumi/pulumi'; const config = new pulumi.Config(); const kubeconfig = config.requireSecret("kubeconfig"); // Ensure that your kubeconfig is set properly in Pulumi configuration. const tykGatewayChart = new k8s.helm.v3.Chart('tyk-gateway', { chart: 'tyk-gateway', version: '0.6.0', // Replace with the version you wish to deploy fetchOpts: { repo: 'https://helm.tyk.io/public/helm/charts/', // The repository where tyk-gateway chart is located. }, // Values from the Helm chart's 'values.yml' can be provided here. values: { gateway: { // Helm chart values go here. } }, }, { provider: new k8s.Provider('k8s-provider', { kubeconfig }) }); export const tykGatewayStatus = tykGatewayChart.status;

    Before running the program, you must set the kubeconfig configuration value:

    pulumi config set kubeconfig --secret "$(cat path/to/kubeconfig/file)"

    This config command sets the kubeconfig in Pulumi's configuration system and marks it as secret, which prevents it from being stored in plaintext. Be sure to replace "path/to/kubeconfig/file" with your actual kubeconfig file path.

    Replace the placeholder values in the values object within the tykGatewayChart declaration with the actual values you wish to set for your tyk-gateway Helm chart deployment. You can find these values in the Helm chart's values.yaml file.

    When your program is ready, you can deploy it using the following commands:

    pulumi stack init dev # Initializes a new stack for your project pulumi up # Preview and deploy changes

    Remember to monitor the Pulumi CLI's output for the status of your deployment. If you encounter any issues, the CLI will display error messages that can help you troubleshoot. After successful deployment, the output will display any exported stack outputs, such as the tykGatewayStatus.

    Please note that this example assumes you already have an OpenShift cluster set up and configured your authentication for Pulumi to interact with Azure. This code will deploy the Helm chart, but depending on the specific tyk-gateway chart configurations, you may need to provide additional configuration details specific to your environment and use case.
