1. Deploy the sonatype-nexus helm chart on Rancher


    To deploy the Sonatype Nexus Helm chart on Rancher using Pulumi, you need to perform the following steps:

    1. Set up Rancher: You must have a Rancher server up and running, and you should configure kubectl to interact with the Kubernetes cluster managed by Rancher.

    2. Install Pulumi: If you haven't already done so, install Pulumi and set up your Pulumi account.

    3. Write the TypeScript program: You'll use Pulumi's Rancher2 provider to interact with Rancher and deploy the Helm chart. Make sure you have Rancher credentials set up for authentication (typically via environmental variables or the Pulumi configuration system).

    Below, you'll find a Pulumi TypeScript program that deploys the Sonatype Nexus Helm chart on Rancher. The program assumes you have the appropriate permissions and configurations to deploy resources on your Rancher-managed Kubernetes cluster.

    Detailed Explanation

    The program begins by importing the required packages. Pulumi's @pulumi/rancher2 package is used to interact with Rancher, and @pulumi/kubernetes is the standard Kubernetes provider to deploy Helm charts.

    The program will use the rancher2.Cluster class to interact with an existing cluster managed by Rancher. The resource for the cluster is instantiated, and the name of the cluster is passed, which is imperative for Pulumi to know which cluster to operate on. We won't be managing the cluster itself in this deployment, so ensure you reference an already running and properly configured cluster.

    Next, a Helm Release is deployed using the Pulumi Kubernetes provider. We define the Sonatype Nexus Helm chart using the Chart class with relevant configuration parameters such as the chart name, version, and any values you want to customize.

    Finally, we will export the cluster name and the Helm release name as stack outputs, which you can use to reference the deployed resources later on. These stack outputs are useful for accessing details about the deployment programmatically or from the Pulumi CLI after the program has run.

    Pulumi TypeScript Program

    import * as rancher2 from "@pulumi/rancher2"; import * as k8s from "@pulumi/kubernetes"; import * as pulumi from "@pulumi/pulumi"; const clusterName = "my-rancher-cluster"; // Replace with the name of your Rancher-managed cluster // Establish a connection to an existing Rancher cluster const cluster = new rancher2.Cluster(clusterName, { name: clusterName, }); // Upon successful connection to the cluster, use the Pulumi Kubernetes provider to deploy the Helm chart const nexusChart = new k8s.helm.v3.Chart("sonatype-nexus", { chart: "sonatype-nexus", version: "1.24.3", // Specify the version of the chart you wish to deploy fetchOpts: { repo: "https://sonatype.github.io/helm3-charts/", // Helm chart repository }, values: { persistence: { enabled: true, storageSize: "10Gi", // Adjust storage size as needed }, // Add more custom values for the Sonatype Nexus Helm chart here }, }, { provider: new k8s.Provider("k8s-provider", { kubeconfig: cluster.kubeConfigRaw }) }); // Export the cluster name and Helm release name, which can be used to reference the resources later on export const rancherClusterName = clusterName; export const sonatypeNexusHelmReleaseName = nexusChart.metadata.apply(m => m.name);

    When running this program with Pulumi, it will deploy the Sonatype Nexus Helm chart on your Rancher-managed Kubernetes cluster. Remember to replace placeholder values, like my-rancher-cluster, with those specific to your environment.

    After you've written this program:

    • Run pulumi up in the directory containing your Pulumi program.
    • Review the resource changes that Pulumi proposes to perform.
    • Confirm the deployment to proceed, and Pulumi will manage the deployment process for you.

    The program output will display the names of created resources, and because of the defined stack exports, you can retrieve your Kubernetes cluster and Helm release names from the Pulumi console or CLI.
