1. Deploy the oidc-gateway helm chart on Linode Kubernetes Engine


    To deploy the OIDC Gateway Helm Chart on the Linode Kubernetes Engine using Pulumi, we will follow these steps:

    1. Set up Linode Kubernetes Engine Cluster: We need to have a Kubernetes cluster on Linode. For this, you'd usually use the @pulumi/linode package to provision a Linode Kubernetes Engine (LKE) cluster. However, as of my knowledge cutoff in early 2023, the Pulumi Linode provider does not directly support managing LKE clusters. You would typically use Linode's Cloud Manager or CLI to create the cluster.

    2. Install and Configure Pulumi Kubernetes Provider: Once you have a Kubernetes cluster running in Linode, you will need to configure the Pulumi Kubernetes provider to interact with your cluster.

    3. Deploy the OIDC Gateway Helm Chart: With the Kubernetes provider configured, you can deploy Helm charts. You will use the kubernetes.helm.v3.Chart resource from the @pulumi/kubernetes package to deploy the OIDC Gateway Helm chart.

    Below is a Pulumi program in TypeScript that illustrates how you would use Pulumi to deploy a Helm Chart to a Kubernetes cluster. Before running this Pulumi program, ensure you have a Linode Kubernetes cluster running and have the kubeconfig file ready on the machine where you are running Pulumi.

    First, install the necessary Pulumi packages by running:

    npm install @pulumi/pulumi @pulumi/kubernetes

    Here is the TypeScript program:

    import * as k8s from '@pulumi/kubernetes'; // Create a provider resource that specifies the kubeconfig details to connect to the Linode Kubernetes cluster const provider = new k8s.Provider('lke-provider', { kubeconfig: '<your kubeconfig here>', }); // Deploy the OIDC Gateway Helm chart using the Chart resource const oidcGatewayChart = new k8s.helm.v3.Chart('oidc-gateway', { chart: 'oidc-gateway', version: '<chart version>', // Specify the version of the chart if necessary namespace: 'default', // Specify the target namespace where the chart should be installed fetchOpts: { repo: 'https://charts.example.com/', // Replace with the actual Helm chart repository that hosts the OIDC Gateway chart }, }, { provider }); // Export the Kubernetes services to access the OIDC Gateway application export const oidcGatewayService = oidcGatewayChart.getResource('v1/Service', 'oidc-gateway');

    Replace <your kubeconfig here> with the contents of your kubeconfig file or the filepath to your kubeconfig. Also, replace the chart version and repo URL with appropriate values for the OIDC Gateway Helm chart you intend to deploy.

    This program starts by importing the @pulumi/kubernetes package which contains the necessary classes and functions to interact with Kubernetes, including deploying Helm charts. A Kubernetes provider is instantiated with the details from the kubeconfig which allows Pulumi to manage resources in the specified cluster.

    The kubernetes.helm.v3.Chart resource is then used to deploy the OIDC Gateway Helm chart. You specify the chart name, the version, and the repository where the Helm chart is located, as well as the Kubernetes namespace where it should be deployed.

    Finally, the program exports the service associated with the OIDC Gateway, allowing you to access the service endpoints after deployment. You would run the Pulumi program with the pulumi up command, which will provision the resources as described in the code.

    Keep in mind that handling Helm repositories and chart versions might change based on how the chart is published and managed, so ensure you have the correct URL for the chart repository and the correct chart name and version.
