1. Deploy the simple-mssql helm chart on Kubernetes


    Certainly! To deploy the simple-mssql Helm chart on Kubernetes using Pulumi, you'll need to follow these steps:

    1. Set up Pulumi: Ensure you have Pulumi CLI installed and you've logged in to your Pulumi account. You should also have kubectl configured to communicate with your Kubernetes cluster.

    2. Create a New Pulumi Project: Start by creating a new Pulumi project using pulumi new and choose the appropriate template for TypeScript.

    3. Install Required Packages: You need to have the Pulumi Kubernetes SDK installed in your project to work with Kubernetes resources. This is done via the package manager for your language; in this case, we'll use npm for TypeScript.

      npm install @pulumi/kubernetes
    4. Write the Pulumi Program: Write the deployment code that specifies the Kubernetes Chart resource for simple-mssql.

    Below is a TypeScript program that performs the helm chart deployment:

    import * as k8s from "@pulumi/kubernetes"; const chartName = "simple-mssql"; const chartVersion = "1.0.0"; // Replace with the correct chart version const releaseName = "simple-mssql-release"; // Deploy simple-mssql helm chart const simpleMssqlChart = new k8s.helm.v3.Chart(releaseName, { chart: chartName, version: chartVersion, fetchOpts: { // Here you can specify options like the repo URL where your chart is located // For example: // repo: "https://charts.bitnami.com/bitnami" }, // If the chart requires you to override values, specify those here: values: { // You might need to set required parameters for your chart here, as an example: // service: { // type: "ClusterIP" // }, // persistence: { // enabled: true, // size: "8Gi" // } } }, { provider: k8sProvider }); // Ensure you pass the correct K8s provider if you're working with multiple clusters // Export the chart's service `loadBalancer` IP if appropriate export const sqlServiceIP = simpleMssqlChart .getResourceProperty("v1/Service", `${releaseName}-${chartName}`, "status") .apply(status => status.loadBalancer?.ingress[0].ip)

    In this piece of code:

    • We import the @pulumi/kubernetes package to interact with Kubernetes resources.
    • simple-mssql is specified as the chart we wish to deploy. Make sure to specify the correct version of the Helm chart in the chartVersion variable. The Helm chart version should match the version you want to deploy.
    • We create a new Helm chart instance using new k8s.helm.v3.Chart. The releaseName variable is the name you want to assign to your Helm release.
    • We pass a configuration object that includes chart, version, and values. The values object is where you can override default chart values as needed. It's common for Helm charts to accept various configurations through this parameter. Refer to the simple-mssql Helm chart documentation to determine the required and available configurable values.
    • In the fetchOpts object inside the config, you'll specify the storage options, such as where to find the chart if it's not in the default Helm repository.
    • Optionally, we export the service IP address which would be relevant if the service that's created by the Helm chart is of type LoadBalancer and you want to make it accessible externally.
    • The last parameter { provider: k8sProvider } is where you pass your provider details. This is especially useful when you are working with multiple Kubernetes clusters; otherwise, it will automatically use the default provider configuration.

    To run this program, you will typically execute pulumi up to preview and deploy the changes. Pulumi compiles the TypeScript code, figures out what needs to be deployed or updated, and shows you a preview. If you confirm, it then proceeds to make the necessary changes to your Kubernetes cluster.

    Don't forget to replace the placeholder values in the fetchOpts, values, and k8sProvider with actual values that match your specific scenario.
