1. Deploy the kanister-mysql helm chart on Kubernetes


    Deploying Helm charts on Kubernetes using Pulumi is a straightforward process. Pulumi provides first-class support for managing Kubernetes resources, including deploying Helm charts, via the Kubernetes provider.

    For your case, we'll be using the kubernetes.helm.v3.Chart resource from Pulumi’s Kubernetes provider to deploy the kanister-mysql Helm chart. This provider allows us to interact with Helm charts as if we were using the Helm CLI, but we get the added benefits of Pulumi's state management and orchestration.

    Here's what you'll need to do in general terms:

    1. Set up Pulumi with the Kubernetes provider.
    2. Define the Helm chart to be deployed within your Pulumi program.
    3. Configure the chart values (if necessary), specifying the details of your MySQL deployment.
    4. Run pulumi up to preview and deploy your resources.

    Let's turn this into a concrete TypeScript program. Below you'll find the full Pulumi program that defines the deployment of the kanister-mysql Helm chart.

    import * as pulumi from "@pulumi/pulumi"; import * as k8s from "@pulumi/kubernetes"; // Step 1: Initialize a Kubernetes provider instance (uses current context from kubeconfig by default) const provider = new k8s.Provider("provider", {}); // Step 2: Define the kanister-mysql Helm chart const mysqlChart = new k8s.helm.v3.Chart("kanister-mysql", { // Assuming the kanister-mysql chart is available in the Helm repository // Specify the repository URL that contains the chart // You would replace "repoUrl" with the actual repository URL repo: "your-helm-chart-repository", // Example: "https://charts.bitnami.com/bitnami" chart: "kanister-mysql", version: "chart-version", // Substitute with the version of the chart you want to deploy // Step 3: Provide any custom values for the chart values: { // These values would configure your kanister-mysql chart // Specify them as per the chart's configurable options // Example: mysqlRootPassword: "your-root-password", mysqlUser: "your-username", mysqlPassword: "your-user-password", mysqlDatabase: "your-database" // Add other configurable values here }, }, { provider: provider }); // Export the chart's name which could be later used to reference the chart in your Kubernetes cluster export const chartName = mysqlChart.metadata.apply(meta => meta.name); // Run the Pulumi CLI command `pulumi up` to deploy your chart

    To explain the code:

    • We first import the necessary Pulumi packages for Kubernetes.
    • We then create an instance of the Kubernetes provider. In this case, we're using the default configuration that assumes the Kubernetes context is already set up in .kube/config.
    • Next, we define a Chart resource representing the kanister-mysql Helm chart. Here, you need to specify the repository URL that houses the chart and any chart values—these are the custom settings you can pass to configure the MySQL chart to suit your needs (like usernames, passwords, and database names).
    • Finally, we export the chartName, which is the name of the deployed Helm chart in your cluster.

    Before running the pulumi up command, ensure that Pulumi is logged in and configured for your Kubernetes cluster. You can check this by running pulumi stack and kubectl config current-context.

    Make sure that the repo and version in the program match the Helm chart repository you want to use. Additionally, you should customize the values map with the appropriate MySQL configuration parameters per the kanister-mysql chart's requirements.

    To execute the deployment, open a terminal in a directory with the above file, then run:

    pulumi up

    Pulumi will show you a detailed preview of what the program will deploy. If everything looks good, confirm the deployment, and Pulumi will execute the changes and deploy your MySQL Helm chart to your Kubernetes cluster.
