1. Deploy the create-mysql-db helm chart on Kubernetes


    To deploy a Helm chart on a Kubernetes cluster using Pulumi, we'll use the kubernetes.helm.sh/v3.Chart resource which is part of the Pulumi Kubernetes provider. This high-level component allows you to deploy Helm charts into a Kubernetes cluster.

    The Chart resource requires the following inputs:

    • chart: The name of the Helm chart to deploy.
    • version: The version of the Helm chart to deploy.
    • fetchOpts: Options to specify the location from where to fetch the Helm chart if it's not from the default Helm repository.
    • namespace: The Kubernetes namespace in which to deploy the Helm chart.
    • values: A set of values to configure the Helm chart.

    Before you begin, ensure you have the following:

    • Helm CLI installed (Helm charts are defined and packaged with Helm).
    • Pulumi CLI installed and set up to manage resources.
    • Access to a Kubernetes cluster configured with kubectl.

    Here's an example program that deploys the create-mysql-db Helm chart to a Kubernetes cluster:

    import * as k8s from "@pulumi/kubernetes"; // Define the namespace where the Helm chart will be installed const namespace = "default"; // Deploy the create-mysql-db Helm chart into the cluster const mysqlChart = new k8s.helm.v3.Chart("create-mysql-db", { namespace: namespace, chart: "create-mysql-db", // The name of the chart // Uncomment and specify the repository if the Helm chart is not in the default Helm repository // fetchOpts: { // repo: "https://charts.example.com/", // }, // Specify the version of the chart you want to deploy version: "1.0.0", // Replace with the desired chart version // Pass in any Helm values required for configuring the chart values: { // These values would be specific to the create-mysql-db Helm chart // Replace with actual values needed to configure your MySQL database mysqlRootPassword: "my-secret-pw", mysqlUser: "user1", mysqlPassword: "user1password", mysqlDatabase: "mydatabase" }, }, {provider: k8sProvider}); // Specify your provider if necessary // When run, this program will apply the Helm chart to your Kubernetes cluster, creating the necessary // resources that define a MySQL database according to the chart's templates and the input values provided.

    Ensure to replace the placeholders in the values section with the actual configurations you want for your MySQL database. Also, make sure that you've selected the right chart version that corresponds to the create-mysql-db chart you wish to deploy.

    To run this Pulumi program:

    1. Save the file with a .ts extension.
    2. Run pulumi up in the terminal from the directory where the file is saved.

    The pulumi up command starts the deployment process which includes:

    • Previewing the changes that will be made to your cluster.
    • Asking for confirmation before proceeding with the deployment.
    • Applying the Helm chart to the cluster which creates the defined Kubernetes resources for MySQL.

    After successful deployment, Pulumi will output the state of the resources in the cluster.

    If you're using a private Helm repository or a chart that's not hosted in the default Helm repository, you'll need to uncomment and modify the fetchOpts property to include the URL of the repository.

    Remember to manage sensitive data like passwords securely, for example by using Pulumi Secrets.

    Deploying this Helm chart with Pulumi provides you with a declarative way to manage your Kubernetes resources in code alongside any other cloud infrastructure in a Pulumi project.
