1. Deploy the keycloak-proxy helm chart on Rancher


    In order to deploy a Helm chart on a Rancher Kubernetes cluster using Pulumi, you would typically perform the following steps:

    1. Setup Rancher Kubernetes Cluster: Ensure you have access to a Rancher-managed Kubernetes cluster. You should have the cluster's kubeconfig file so that Pulumi can interact with your cluster.
    2. Install Helm and Rancher 2 Pulumi Providers: You must have the Helm and Rancher 2 Pulumi providers installed in your environment to deploy Helm charts on a Rancher cluster.
    3. Write Pulumi Code: Write the code to use the Helm and Rancher 2 providers for deploying the keycloak-proxy chart.

    The program below is a basic TypeScript Pulumi program that demonstrates how to deploy a Helm chart into a Rancher Kubernetes cluster. Please remember to have your kubeconfig set up properly in your environment, as Pulumi will rely on this configuration to communicate with your Kubernetes cluster.

    import * as k8s from '@pulumi/kubernetes'; import * as pulumi from '@pulumi/pulumi'; import * as rancher2 from '@pulumi/rancher2'; // Configuration variables for the deployment const keycloakProxyChartName = "keycloak-proxy"; const keycloakProxyChartVersion = "1.0.0"; // Replace with the desired chart version const keycloakProxyReleaseName = "keycloak-proxy-release"; const keycloakProxyNamespace = "default"; // Replace with the namespace where you want to deploy // Reference to the Rancher-managed Kubernetes cluster // Depending on how you set up, you might need to fetch the cluster details differently. const cluster = new rancher2.Cluster("my-cluster", {/* ... properties ... */}); // Create a provider for the specified cluster. const k8sProvider = new k8s.Provider("k8s-provider", { kubeconfig: cluster.kubeConfig, }); // Deploy keycloak-proxy using the Helm Chart const keycloakProxy = new k8s.helm.v3.Chart(keycloakProxyReleaseName, { namespace: keycloakProxyNamespace, fetchOpts:{ repo: "http://path-to-your-helm-chart-repo/", // Replace with your Helm chart repo URL }, chart: keycloakProxyChartName, version: keycloakProxyChartVersion, }, { provider: k8sProvider }); // Export the public URL for the keycloak-proxy (if applicable) export const keycloakProxyUrl = keycloakProxy.status.apply(status => status.loadBalancer?.ingress[0]?.hostname ?? status.loadBalancer?.ingress[0]?.ip);


    • @pulumi/kubernetes is the Pulumi Kubernetes provider which allows us to work with Kubernetes resources.
    • @pulumi/rancher2 is the Pulumi provider for Rancher 2.x. It allows for managing Rancher resources using Pulumi.
    • We define configuration variables for the Helm chart name, version, release name, and the Kubernetes namespace.
    • We instantiate a reference to our Rancher cluster using rancher2.Cluster, which is necessary to create a Kubernetes provider that Pulumi can work with.
    • We construct a Kubernetes provider k8s.Provider. This provider uses the kubeconfig from the Rancher cluster to interact with the cluster.
    • We use the k8s.helm.v3.Chart to deploy the Helm chart. This requires specifying the namespace, chart name, and version. Also, we need to provide the Helm chart repository URL. Pulumi will handle the deployment of the chart to your Rancher cluster.
    • Finally, we export a public URL, which would be the way to access the keycloak-proxy once it's deployed. Note that this step depends on how the service is exposed and may vary.

    Before running the code:

    • Install @pulumi/rancher2 and @pulumi/kubernetes using npm:
      npm install @pulumi/rancher2 @pulumi/kubernetes
    • Configure kubeconfig so that Pulumi can communicate with your Rancher Kubernetes cluster.
    • You should customize the rancher2.Cluster instantiation with the actual details of your Rancher 2.x Kubernetes cluster.
    • Replace the keycloakProxyChartVersion and the Helm repo URL with the appropriate values for your deployment.

    To apply this Pulumi program, run pulumi up via the Pulumi CLI. This will provision the resources described in the program. Ensure you have Pulumi installed and are authenticated against the desired cloud and Pulumi backend.
