1. Deploy the old-joomla helm chart on Kubernetes


    Deploying the old-joomla Helm Chart on Kubernetes with Pulumi

    Helm Charts provide a way to deploy and manage applications on a Kubernetes cluster. With Pulumi, you can orchestrate the deployment of Helm charts programmatically. We'll use Pulumi's Kubernetes provider to deploy the "old-joomla" Helm chart, which is a package that encapsulates the Joomla application, its dependencies, and its deployment configuration.

    We will go through the process of setting up a Pulumi program in TypeScript that accomplishes this. The program will:

    1. Set up a Kubernetes Provider that interacts with your cluster.
    2. Use the Chart resource from the Pulumi Kubernetes provider to deploy the "old-joomla" Helm chart.

    Before you start, make sure you have the following prerequisites in place:

    • Pulumi CLI installed and configured with your chosen cloud provider.
    • Access to a Kubernetes cluster (with kubectl configured to connect to it).
    • Helm tool installed (used to locate the "old-joomla" chart's repository or for local chart paths).

    Here is the TypeScript program that deploys the "old-joomla" Helm chart to your Kubernetes cluster:

    import * as k8s from "@pulumi/kubernetes"; const chartName = "old-joomla"; const chartVersion = "x.y.z"; // Replace x.y.z with the chart's version you wish to deploy const chartRepo = "https://charts.bitnami.com/bitnami"; // Replace with the repository URL where the chart is hosted // Deploying the old-joomla Helm chart to the Kubernetes cluster const joomlaChart = new k8s.helm.v3.Chart("old-joomla-chart", { chart: chartName, version: chartVersion, fetchOpts: { repo: chartRepo }, // Specify the values you'd like to override. // This would be equivalent to the --set flag when using the Helm CLI. values: { // Add custom values here which are specific to the old-joomla chart // e.g., cpu: "100m" } }); export const joomlaChartName = joomlaChart.metadata.name;

    In this program:

    • We import the Kubernetes package from Pulumi which allows us to interact with our cluster.
    • We declare constants for the name, version, and repository URL of the chart we're deploying. You must replace "x.y.z" with the actual version of the "old-joomla" chart you want to deploy.
    • The k8s.helm.v3.Chart class is instantiated to create a new Helm chart resource. The chart's name, version, and repository options are provided to locate the correct Helm chart.
    • Within the values object of the chart, you can provide overrides for default Helm chart values. This step is optional and depends on the configuration you would like for Joomla.
    • We export the name of the deployed Helm chart to use as a reference if needed.

    To deploy this program:

    1. Save the code to a file with a .ts extension, for example, deployJoomla.ts.
    2. Run pulumi up in the same directory as your .ts file. Pulumi CLI will interact with your Kubernetes cluster to deploy the chart.

    After you run pulumi up, Pulumi performs the deployment, and you should see outputs indicating the status of the resources being deployed. If you've set everything up correctly, "old-joomla" should be deployed to your Kubernetes cluster.

    Remember to replace the chartVersion and chartRepo with actual versions and repository URLs. You can find the "old-joomla" Helm chart info and available versions from Helm chart repositories or artifact hubs that host Helm charts.
