1. Deploy the wordpress-apache helm chart on Rancher

    TypeScript

    To deploy the wordpress-apache helm chart on a Rancher-managed cluster using Pulumi, you'll need to interact with Kubernetes resources through Pulumi's Rancher2 provider. Here, we'll assume that you have Rancher server running and have access to it. Moreover, you need to have a Kubernetes cluster already managed by Rancher.

    For this task, you'll primarily be using two kinds of Pulumi resources:

    1. rancher2.CatalogV2: This resource is used to add a new catalog to Rancher, which is a repository of Helm charts. You'll need to add the catalog that contains the wordpress-apache chart.

    2. Kubernetes-related resources:

      • helm.v3.Chart: This is a Pulumi resource provided by the @pulumi/kubernetes package, which is used to deploy applications packaged as Helm charts. You will use this to deploy the wordpress-apache chart once it is available in the Rancher catalog.

    Here's a brief outline of the steps in TypeScript:

    1. Instantiate a rancher2.CatalogV2 resource to add the necessary Helm chart repository to Rancher.
    2. Use the helm.v3.Chart resource to deploy the chart from the added catalog.

    Now, let's set up the program:

    import * as rancher2 from "@pulumi/rancher2"; import * as k8s from "@pulumi/kubernetes"; import * as pulumi from "@pulumi/pulumi"; // Create a new Rancher2 Catalog V2 to add the repository containing the wordpress-apache chart const catalog = new rancher2.CatalogV2("wordpress-catalog", { // Provide the URL to the repository containing the wordpress-apache helm chart url: "https://charts.bitnami.com/bitnami", // Specify the Helm chart repository branch gitBranch: "master", // Indicate the cluster ID where the catalog should be added clusterId: "<YOUR-RANCHER-CLUSTER-ID>", }); // Deploy the wordpress-apache Helm chart using the helm.v3.Chart resource from the Pulumi Kubernetes provider const wordpressApacheChart = new k8s.helm.v3.Chart("wordpress-apache", { // Reference the chart from the added catalog chart: "wordpress", // Specify the version of the chart to deploy; check the repository for the latest version version: "11.1.5", // Define the namespace where the application should be deployed, you may need to create this namespace separately namespace: "default", // Provide the values to customize the Wordpress Apache deployment according to your needs values: { mariadb: { auth: { rootPassword: "my-root-password", database: "wordpress", username: "wordpress", password: "wordpress-password", }, }, wordpressUsername: "admin", wordpressPassword: "admin-password", wordpressEmail: "user@example.com", wordpressFirstName: "FirstName", wordpressLastName: "LastName", wordpressBlogName: "User's Blog!", }, }, { dependsOn: [catalog] }); // Ensure the Catalog V2 is created before deploying the chart // Exporting the WordPress service endpoint for easy access export const wordpressEndpoint = wordpressApacheChart.getResourceProperty("v1/Service", "wordpress-apache-wordpress", "status").apply(status => status.loadBalancer.ingress[0].ip);

    In this program:

    • A new Rancher Catalog (CatalogV2) is created, which adds the repository containing wordpress-apache Helm charts to your Rancher cluster.
    • A Helm chart resource (helm.v3.Chart) representing the wordpress-apache deployment is created. It points to the chart wordpress in the previously added catalog repository. The version and values are specified for deploying WordPress with Apache.
    • An export statement is included for the WordPress service endpoint, which will display the IP address of the load balancer providing access to your Wordpress site after deployment.

    Make sure to replace <YOUR-RANCHER-CLUSTER-ID> with the actual cluster ID where your Rancher-managed Kubernetes is running. Similarly, customize any of the values fields to match your desired WordPress setup (like passwords, database names, etc.).

    Before running this program, ensure you have Pulumi CLI installed and configured with the required cloud provider credentials. After setting up, run pulumi up to deploy the WordPress Apache helm chart onto your Rancher-managed Kubernetes cluster.
