1. Deploy the keycloak-client-controller helm chart on Rancher

    TypeScript

    To deploy the keycloak-client-controller Helm chart on Rancher using Pulumi, you'll need to follow these steps:

    1. Set up Rancher and get access to it.
    2. Ensure you have a Kubernetes cluster managed by Rancher where you want to deploy the chart.
    3. Use Pulumi's Rancher2 provider to interact with your Rancher instance.

    Let's assume you already have a Kubernetes cluster set up and it's being managed by Rancher. You'll need to get the cluster ID that Rancher uses to identify your cluster. This information can typically be found in the Rancher dashboard for your cluster.

    The Pulumi program will perform the following actions:

    • Create a namespace on the Kubernetes cluster if it does not already exist.
    • Deploy the keycloak-client-controller Helm chart into that namespace.

    Here's a detailed Pulumi program in TypeScript that will deploy the Helm chart:

    import * as rancher2 from "@pulumi/rancher2"; import * as k8s from "@pulumi/kubernetes"; import * as pulumi from "@pulumi/pulumi"; // Create a provider to interact with your Rancher instance. const rancherProvider = new rancher2.Provider("rancher", { api_url: "https://your-rancher-api-url", accessKey: "your-rancher-access-key", secretKey: "your-rancher-secret-key", }); // Specify the cluster ID where the Helm chart should be deployed. // You can find this in the Rancher dashboard. const clusterId = "your-cluster-id"; // Create a new k8s provider that uses the cluster selected through Rancher. const k8sProvider = new k8s.Provider("k8s", { kubeconfig: rancherProvider.clusterKubeconfig(clusterId), }); // Create a namespace for the Keycloak client controller if it doesn't already exist. const namespace = new k8s.core.v1.Namespace("keycloak-namespace", { metadata: { name: "keycloak-client-controller-ns" }, }, { provider: k8sProvider }); // Deploy the keycloak-client-controller Helm chart. const keycloakClientControllerChart = new k8s.helm.v3.Chart( "keycloak-client-controller", { namespace: namespace.metadata.name, chart: "keycloak-client-controller", // Specify the Helm repository which contains the chart if it's not a default one. // 'repo' parameter can be omitted if the chart is available in the default repos. fetchOpts: { repo: "http://your-helm-chart-repository-url" }, // If you have values to override the default ones, specify them here. // values: { ... } }, { provider: k8sProvider } ); // Export the endpoint of Keycloak client controller if there is any service of LoadBalancer type export const keycloakClientControllerEndpoint = keycloakClientControllerChart.getResourceProperty("v1/Service", "keycloak-client-controller", "status").apply(status => status.loadBalancer.ingress[0].ip || status.loadBalancer.ingress[0].hostname);

    Explanation of the code block:

    • We first set up the rancher2.Provider with the necessary credentials to interact with the Rancher API.
    • We set the clusterId of the target Kubernetes cluster managed by Rancher.
    • We create a k8s.Provider which uses the clusterKubeconfig associated with the specified clusterId.
    • We then declare a Kubernetes namespace using Pulumi's Kubernetes provider. This namespace will provide a logical separation for our resources related to Keycloak on the Kubernetes cluster.
    • We deploy the keycloak-client-controller Helm chart using the k8s.helm.v3.Chart resource and specify the namespace we created. If you need to override chart values or specify a custom repository, you can do so in the respective properties.
    • Lastly, if the Keycloak client controller exposes an endpoint through a LoadBalancer service, we export its endpoint for external access.

    Before running this program, replace https://your-rancher-api-url with the URL to your Rancher API, your-rancher-access-key and your-rancher-secret-key with your credentials for Rancher, your-cluster-id with the actual cluster ID, and http://your-helm-chart-repository-url with the URL to the repository where the keycloak-client-controller chart is stored.

    To run the above Pulumi program, save it in a file with a .ts extension, and then use the Pulumi CLI to create a new stack and deploy it. Make sure you have the Pulumi CLI and your preferred cloud provider CLI installed and configured on your system.

    Please ensure that you have configured access to your Kubernetes cluster and have the necessary permissions to deploy resources within the cluster. The kubeconfig file of your cluster will be used by Pulumi to connect and deploy the resources.
