1. Deploy the nginx-ldapauth-proxy helm chart on Azure Managed Openshift Service


    To deploy the nginx-ldapauth-proxy Helm chart on Azure Managed OpenShift Service using Pulumi, you will need to set up a few things:

    1. Azure Managed OpenShift Service: You need to provision an OpenShift Managed Cluster in Azure. This can be done using the azure-native.containerservice.OpenShiftManagedCluster resource.
    2. Helm Chart: After setting up your OpenShift cluster, you will deploy the Helm chart for nginx-ldapauth-proxy. This can be achieved using kubernetes.helm.v3.Chart resource, which is a custom Pulumi resource for deploying Helm charts on a Kubernetes cluster.

    Let's go through the code to set this up. I'll explain each part of the process:

    Step 1: Configure Azure Managed OpenShift Service

    We will define the necessary resources to create an Azure Managed OpenShift cluster.

    • You must have the Azure CLI configured with the necessary credentials and permissions to create resources within your subscription.
    • We will use the azure-native.containerservice.OpenShiftManagedCluster resource to create the cluster.

    Step 2: Deploy the Helm Chart

    After our OpenShift Cluster is up and running, we will deploy the nginx-ldapauth-proxy using the Helm chart.

    • For this, we will need to install the @pulumi/kubernetes and @pulumi/azure-native packages.
    • We will use the kubernetes.helm.v3.Chart resource to deploy a Helm chart onto our cluster.

    Pulumi Program

    We will now put it all together into a Pulumi program written in TypeScript. This program assumes you've already authenticated with Azure and have the necessary permissions.

    Here is the code to accomplish the deployment:

    import * as pulumi from "@pulumi/pulumi"; import * as azure from "@pulumi/azure-native"; import * as k8s from "@pulumi/kubernetes"; // Step 1: Instantiate an Azure Managed OpenShift Cluster const managedCluster = new azure.containerservice.OpenShiftManagedCluster("myOpenShiftManagedCluster", { // Provide required properties like location and other cluster configuration details location: "East US", // You should update this to the location you desire resourceName: pulumi.interpolate`openshift-managed-${pulumi.getStack()}`, // A unique name for your OpenShift Managed Cluster resourceGroupName: "resourceGroupName", // Your existing or new resource group name openShiftVersion: "v4.3", // Specify the OpenShift version // Define agent and master pool profiles among other properties according to your specific needs agentPoolProfiles: [{ name: "agentpool", count: 3, vmSize: "Standard_DS2_v2", // You can choose the appropriate VM size }], masterPoolProfile: { count: 3, vmSize: "Standard_DS2_v2", // You can choose the appropriate VM size }, // ... other necessary configurations }); // Step 2: Deploy the nginx-ldapauth-proxy helm chart const nginxLdapAuthProxyChart = new k8s.helm.v3.Chart("nginx-ldapauth-proxy", { chart: "nginx-ldapauth-proxy", // The repo where your Helm chart is located // You'll likely need to replace this with the actual repository URL or path to your chart repo: "https://my-helm-chart-repository/", // Define values for the Helm chart based on your specific configuration needs values: { ldap: { url: "ldap://my-ldap-server", // ... additional LDAP configurations }, // ... other configurations specific to nginx-ldapauth-proxy }, // You must specify the namespace for which you have permissions to deploy Helm charts namespace: "default", // Fetch the namespace from the cluster where the Helm Chart is going to be installed fetchOpts: { // This is where you can provide specific options for fetching the Helm chart, if needed }, }, { provider: new k8s.Provider("k8s-provider", { kubeconfig: managedCluster.kubeconfig }) }); // Export the URL for the nginx-ldapauth-proxy service export const nginxLdapAuthProxyUrl = pulumi.interpolate`http://${nginxLdapAuthProxyChart.getResourceProperty("v1/Service", "nginx-ldapauth-proxy-svc", "status").loadBalancer.ingress[0].ip}`;

    Make sure to replace placeholders (resourceGroupName, ldap://my-ldap-server, https://my-helm-chart-repository/, etc.) with actual values that correspond to your environment and configuration. Also, as per your OpenShift and Helm configuration, further properties might be needed.

    Please note that deploying infrastructure with Pulumi can incur costs associated with the resources managed by Pulumi, so ensure to check the pricing for resources created in Azure.

    Once you've written your program, you can execute it using the Pulumi CLI with the following commands:

    pulumi up

    This will show you a preview of the resources that will be created, modified, or deleted. Confirm the changes to start the deployment. When the deployment is finished, you can use the exported nginxLdapAuthProxyUrl to access the NGINX proxy server.

    Remember that it's essential to review and understand the code, making any necessary adjustments for your use case, such as setting appropriate resource names, regions, and config values.
