1. Deploy the mtls helm chart on Opensshift


    To deploy a Helm chart with mTLS (mutual TLS) on an OpenShift cluster using Pulumi, you would use the kubernetes.helm.v3.Chart resource from the Pulumi Kubernetes provider. This allows you to deploy Helm charts into your Kubernetes or OpenShift cluster, handled by Pulumi in a similar way as if you were using helm install or helm upgrade CLI commands.

    Given that OpenShift is essentially Kubernetes with additional features and a slight variation in setup, you should be able to use Pulumi's Kubernetes provider to manage resources on OpenShift without major differences.

    To ensure mTLS is configured, you would typically have a Helm chart that contains the necessary Kubernetes resource definitions set up for mTLS, or you would add custom values to the Helm chart that configure mTLS as required. In a typical Helm chart deployment, this could involve configuring a Service, Ingress or Route (in OpenShift terms), and creating the necessary Secrets that hold your TLS certificates and keys.

    Here's an overview of how to accomplish this using Pulumi with TypeScript:

    1. Set up your Pulumi project: You will need a Pulumi project set up with the right configuration for your OpenShift cluster. Make sure you have access to the cluster from the environment where you're running Pulumi.

    2. Install the Pulumi CLI and configure access: Make sure you have the Pulumi CLI installed and configure it to access your OpenShift cluster, usually by setting up your kubeconfig file.

    3. Create a new TypeScript Pulumi program: You'll write your deployment logic in TypeScript, utilizing the Pulumi SDK.

    4. Define Helm chart deployment logic: Use the Chart resource from Pulumi's Kubernetes provider to deploy your mTLS-configured Helm chart to OpenShift.

    Now, let's turn this overview into a Pulumi program:

    import * as k8s from '@pulumi/kubernetes'; const openShiftNamespace = 'your-namespace'; // Replace with your namespace const helmChartName = 'your-helm-chart-name'; // Replace with your Helm chart name const helmChartVersion = 'your-chart-version'; // Replace with the chart version you want to deploy // Define the Helm chart deployment const mTLSChart = new k8s.helm.v3.Chart('mtls-chart', { // Adjust these values to point to your Helm chart's repository and necessary configurations chart: helmChartName, version: helmChartVersion, namespace: openShiftNamespace, fetchOpts: { // If your Helm chart is in a private repository, specify credentials here }, values: { // Add necessary values to configure mTLS for your deployments }, }, { provider: /* specify your OpenShift provider if required */ }); // Export the application URL export const appUrl = mTLSChart.getResourceProperty('v1/Service', 'my-service', 'status.loadBalancer.ingress[0].hostname');

    Explanation of the code:

    • We import the Kubernetes package (@pulumi/kubernetes) to interact with Kubernetes resources, including OpenShift.

    • A namespace is defined for deployment; replace 'your-namespace' with the namespace you want to deploy to in OpenShift.

    • The Helm chart name and version variables (helmChartName and helmChartVersion) should be replaced with the name and version of the chart you want to install.

    • With the Chart resource, we instruct Pulumi to deploy the Helm chart into the specified namespace. Adjust chart, version, and fetchOpts to suit your Helm chart's repository details and any other configurations.

    • In the values object, you would supply your own overrides for chart values to enable and configure mTLS. This part is highly dependent on the chart itself and how it expects mTLS to be configured.

    • The optional provider argument can be specified if you are managing multiple Kubernetes clusters or have a specific configuration for your OpenShift provider.

    • Finally, we define an export appUrl that will give us the URL to access the deployed service. Note that the actual property to export might differ based on the service and the Helm chart you are using.

    Keep in mind that to successfully run this Pulumi program, you must replace the placeholder values with accurate information from your Helm chart and OpenShift environment. Additionally, ensure all required Helm values for mTLS configuration are appropriately set in the values object.

    Before running this program with pulumi up, ensure your Pulumi stack is properly configured with access to your OpenShift cluster, and that the commands are run in an environment where kubectl is configured with the correct context for your cluster.
