1. Deploy the dotnet helm chart on Kubernetes


    To deploy a Helm chart for a .NET application on Kubernetes using Pulumi, you will primarily use the Chart resource from the Pulumi Kubernetes provider. The Chart resource allows you to deploy Helm charts to a Kubernetes cluster.

    Here's a step-by-step TypeScript program that will accomplish this:

    1. Import the necessary Pulumi and Kubernetes packages.
    2. Create a new Kubernetes chart instance, specifying the .NET Helm chart you want to deploy.
    3. Pass any required or custom values that you want to override in the Helm chart using the values property.

    Below is the complete TypeScript program to deploy a .NET Helm chart on Kubernetes. Make sure to replace "dotnet-chart" with the actual name of the Helm chart that contains your .NET application, and set any values that are required for your specific chart.

    import * as k8s from "@pulumi/kubernetes"; // Create a new Kubernetes Chart for the .NET application using a Helm Chart. // Replace "dotnet-chart" with the name of your actual .NET Helm chart. // Ensure your Helm chart is in a repository that is accessible or use a local path. const dotnetChart = new k8s.helm.v3.Chart("dotnet-helm-chart", { chart: "dotnet-chart", // Specify the name of the chart. values: { // Set values to customize your Helm chart. // These values depend on what the Helm chart exposes. // For example: // replicaCount: 2, // image: { // repository: "your-docker-image-repository", // tag: "your-image-tag", // }, }, }); // Export the service name and endpoint of the deployed .NET application. export const serviceName = dotnetChart.getResourceProperty("v1/Service", "dotnet-service", "metadata.name"); export const serviceEndpoint = dotnetChart.getResourceProperty("v1/Service", "dotnet-service", "status.loadBalancer.ingress[0].hostname");

    This Pulumi program will deploy the specified Helm chart to your Kubernetes cluster. It's important to tailor the values to your specific chart as this is where you configure the deployment properties, such as the image to use, the number of replicas, and other configuration settings specific to your application.

    Make sure you have Pulumi set up with access to a Kubernetes cluster. If you are using a remote cluster, such as an AKS, EKS, or GKE cluster, ensure you have the kubeconfig file set up correctly, so Pulumi can interact with your cluster.

    The dotnetChart constant represents the Helm chart to be deployed. The chart option specifies the name of the chart, and values is an object where you will pass any values you want to override in the chart's default configuration. The values you pass will depend on the specific chart you are working with.

    In the export statements, we retrieve the properties of the deployed service to see the name of the service and the ingress endpoint once the application is deployed and accessible. These will be printed to your console after pulumi up completes successfully.

    To run this code:

    • Save the code to a file with a .ts extension, for example, deployDotnetChart.ts.
    • Make sure you have the Pulumi CLI installed and setup with Kubernetes access.
    • Run pulumi up in the same directory as your file to launch the deployment.
