1. Deploy the mysql-client helm chart on Kubernetes


    To deploy the mysql-client Helm chart on Kubernetes using Pulumi, you'll need to have a Kubernetes cluster available and configured to interact with Pulumi. Then you can create a Pulumi program in TypeScript to define and deploy your Helm release.

    The main resource we'll use for this purpose is the Chart resource from the @pulumi/kubernetes package, which represents a Helm chart deployable into a Kubernetes cluster.

    Here’s a step-by-step guide to help you understand the process:

    1. Setting Up the Pulumi Program:

      • Start by importing the necessary Pulumi and Kubernetes packages.
      • Define a Helm chart using the Chart class, specifying the chart details such as name, version, and any custom values you wish to override.
    2. Specifying Chart Details:

      • The chart parameter is the name of the chart you want to deploy, mysql-client in this case.
      • The version parameter is optional and specifies which version of the chart to deploy. If omitted, the latest version will be used.
      • Use values to override any default settings in the chart with your desired configuration.
    3. Running the Pulumi Program:

      • After writing your Pulumi program, use pulumi up to preview and deploy your resources.

    Let’s look at the TypeScript code that accomplishes this:

    import * as pulumi from "@pulumi/pulumi"; import * as kubernetes from "@pulumi/kubernetes"; // Create a Kubernetes namespace for the mysql-client. const namespace = new kubernetes.core.v1.Namespace("mysql-client-ns", { metadata: { name: "mysql-client", }, }); // Deploy the mysql-client Helm chart into the Kubernetes cluster. const mysqlClientChart = new kubernetes.helm.v3.Chart("mysql-client", { namespace: namespace.metadata.name, chart: "mysql-client", // Specific version of the Helm chart can be provided; otherwise, the latest is used by default. version: "1.6.5", fetchOpts: { repo: "https://charts.bitnami.com/bitnami", }, // If you have custom values you want to override, you can specify them here. values: { // Example of setting a value, replace with actual values needed for the mysql-client chart. // image: { // repository: "custom-mysql-client-image", // tag: "latest", // }, }, }, { provider: clusterProvider }); // Ensure you provide the cluster provider if you're not using the default one. // Export the Namespace name and Helm Chart status. export const namespaceName = namespace.metadata.name; export const mysqlClientChartStatus = mysqlClientChart.status;

    In the above TypeScript code, the crucial points are:

    • new kubernetes.core.v1.Namespace() is used to create a namespace in Kubernetes where you will deploy your mysql-client.
    • new kubernetes.helm.v3.Chart() is used to declare a Helm chart resource, where you specify the chart parameter with the name mysql-client and other optional parameters as needed.
    • The fetchOpts property has an repo attribute specifying the repository URL of the Helm chart. Ensure that this URL is where your mysql-client chart is hosted.
    • values is an object that holds any values you want to override in the default Helm chart configuration.
    • The provider option is mentioned as a placeholder. If you're using a non-default Kubernetes provider, you'll need to pass the appropriate provider instance here.

    To apply the above Pulumi program, run pulumi up. This command will provision the specified resources on the Kubernetes cluster, and you can see the output reflecting the resources created or updated. If the mysql-client you're referring to requires any specific values or is located in a different chart repository, be sure to update the program accordingly.
