1. Deploy the ingress-azure helm chart on Kubernetes


    Deploying a Helm chart using Pulumi generally involves the following steps:

    1. Configuring Pulumi to use the correct Kubernetes context, which is typically done outside of the program you write. You would ensure that kubectl is already configured to point to your Kubernetes cluster where you intend to deploy the chart.

    2. Using the Pulumi Kubernetes provider to interact with your Kubernetes cluster.

    3. Using the Chart resource from the Pulumi Kubernetes provider to deploy a Helm chart to your cluster.

    Below is a Pulumi TypeScript program that demonstrates how to deploy the ingress-azure Helm chart to your Kubernetes cluster. In this example, I'm assuming that the Helm chart is available in a Helm repository.

    First, you will need to install the necessary Pulumi CLI and the Pulumi Kubernetes package which could be done with the following npm commands:

    npm install @pulumi/pulumi npm install @pulumi/kubernetes

    Now, here is the Pulumi program:

    import * as k8s from "@pulumi/kubernetes"; // Define the Helm chart repository. const chartRepo = "https://appgwingress.blob.core.windows.net/ingress-azure-helm-package/"; // Define the chart version you want to deploy. const chartVersion = "1.2.3"; // Replace with the specific version you need // Create an instance of the Chart class to deploy the ingress-azure chart from the Helm repository. const ingressAzure = new k8s.helm.v3.Chart("ingress-azure", { repo: "ingress-azure", // The name of the Helm chart repository chart: "ingress-azure", // The name of the chart in the repository version: chartVersion, // The exact version of the chart you want to install fetchOpts: { repo: chartRepo, // The URL of the chart repository }, // Optionally, you can specify the values you want to customize in the Helm chart. values: { // Insert any values you wish to override, e.g., // controller: { // replicaCount: 2, // }, }, }); // Export the public IP address of the ingress, if applicable. export const ingressIp = ingressAzure.getResourceProperty( "v1/Service", "<name-of-the-ingress-service>", "status" ).apply(status => { const ingressStatus = status as k8s.types.output.core.v1.ServiceStatus; return ingressStatus.loadBalancer.ingress[0].ip; });

    Here is what the program does:

    1. Imports the Pulumi Kubernetes SDK.

    2. Sets up the chart repository details where Pulumi can fetch the ingress-azure Helm chart. In our case, we specify the URL for the Azure Application Gateway Ingress Controller Helm repository.

    3. Defines the version of the ingress-azure Helm chart that you would like to deploy. It is a best practice to use explicit versions for reproducibility.

    4. Creates a Helm chart resource using Pulumi's k8s.helm.v3.Chart class, which will install or update the ingress-azure chart in your Kubernetes cluster. It requires some parameters like the repository name, chart name, version, and repository URL.

    5. Optionally, you can pass a values object that customizes the Helm chart with specific configurations. These values override the defaults provided by the Helm chart.

    6. Lastly, the program exports the public IP address of the ingress service. This assumes that the service is of type LoadBalancer and that it is correctly annotated to receive a public IP address.

    Make sure to replace <name-of-the-ingress-service> with the actual name of the service used by the ingress-azure chart. The name can usually be found in the chart's documentation or by inspecting the resources created by the chart in your Kubernetes cluster.

    You would run this program using Pulumi CLI commands pulumi up to deploy the chart and pulumi stack output ingressIp after deployment to retrieve the public IP address of the ingress controller. Please note that you need to have Pulumi installed and set up correctly with your cloud provider's credentials and the Kubernetes context.
