1. Deploy the orangehrm helm chart on Rancher

    TypeScript

    To deploy the orangehrm Helm chart on a Rancher-managed Kubernetes cluster using Pulumi, you will need to use the Rancher2 provider to work with the Rancher API. Below are the steps we will follow to deploy the Helm chart on Rancher:

    1. Set up a Rancher Cluster: We'll define a cluster in Rancher where the Helm chart will be deployed. This can be an existing cluster or a new one created using Pulumi.
    2. Create a Namespace: Helm charts are typically deployed into a specific namespace within a Kubernetes cluster. We define a namespace for the orangehrm application.
    3. Install the Helm Chart: Using Pulumi's support for Helm charts, we'll deploy orangehrm into the specified namespace.

    Here is how you achieve this using Pulumi with TypeScript:

    import * as pulumi from "@pulumi/pulumi"; import * as rancher2 from "@pulumi/rancher2"; import * as k8s from "@pulumi/kubernetes"; // Step 1: Ensure you have a Rancher Kubernetes cluster already created // and configured, or you can create a new one using Pulumi with rancher2.Cluster. // Assuming `rancherCluster` is your existing cluster object fetched using `rancher2.Cluster.get`. // Replace `<YOUR-CLUSTER-ID>` with your actual cluster ID and provide the proper name. const rancherCluster = rancher2.Cluster.get("existing-cluster", "<YOUR-CLUSTER-ID>"); // Step 2: Create a new namespace for the orangehrm application const appNameSpace = new rancher2.Namespace("orangehrm-namespace", { projectId: rancherCluster.defaultProjectId, // Use the default project ID of your Rancher Cluster. name: "orangehrm", // Name for the namespace in which the Helm chart will be deployed. // Add any additional labels or annotations if required // labels: { "mylabel": "value" }, // annotations: { "myannotation": "value" } }); // Step 3: Deploy the orangehrm Helm chart in the namespace const orangehrmChart = new k8s.helm.v3.Chart("orange-hrm", { chart: "orangehrm", version: "X.Y.Z", // Replace with the specific chart version you want to deploy namespace: appNameSpace.metadata.name, // Use the namespace created above fetchOpts: { // Define Helm repository options here where the orangehrm chart is located // You need the repo URL where the orangehrm chart can be found repo: "https://charts.bitnami.com/bitnami", // This is an example Helm repo URL }, // Define values according to the orangehrm Helm chart's requirements values: { // Custom values for the Helm chart, i.e., the configurations required for orangehrm // These will vary depending on the chart you are installing }, }, { provider: new k8s.Provider("k8s-provider", { kubeconfig: rancherCluster.kubeConfig }) }); // Ensure to provide kubeconfig from Rancher cluster // Export the namespace and app URL if needed export const namespaceName = appNameSpace.metadata.name; // The app URL will usually be the LoadBalancer service endpoint, if orangehrm is exposed // Replace `service-name` with the actual service name for orangehrm if different export const appUrl = pulumi.interpolate`http://${appNameSpace.metadata.name}.example.com`;

    Notes on the above code:

    • The Helm chart and the version should match the chart you want to deploy. Make sure to replace "orangehrm" and "X.Y.Z" with the correct chart name and version.
    • The fetchOpts should point to the Helm repository that hosts the orangehrm chart.
    • In the values: Customize the deployment settings based on the configuration options available for the orangehrm Helm chart.
    • In the k8s.Provider: We create a Kubernetes provider instance that points to the Rancher cluster by providing the kubeconfig from the fetched Rancher cluster.

    This Pulumi program will connect to your Rancher-managed Kubernetes cluster, create a namespace for orangehrm, and deploy the Helm chart into that namespace. To apply these changes, simply execute pulumi up in your terminal from the directory where this code is saved, and Pulumi will perform the deployment as specified.
