Deploy the keycloak-configurator helm chart on Rancher

Question

Pulumi · Accepted Answer

To deploy the `keycloak-configurator` Helm chart on a Kubernetes cluster managed by Rancher, follow these steps:

1. Have a Kubernetes cluster managed by Rancher already running.
2. Add the Helm chart repository that contains the `keycloak-configurator` chart to your Helm configuration.
3. Use Pulumi to define a chart resource that refers to the `keycloak-configurator` chart in that repository.

In the following TypeScript Pulumi program, I assume:

- You have a running Kubernetes cluster that is registered with a Rancher instance.
- You have necessary permissions to interact with the cluster and deploy resources to it.
- You have already set up Pulumi to work with your Kubernetes cluster.

Firstly, you need to use the `@pulumi/rancher2` package that provides integration with Rancher 2.x. This enables Pulumi to work with Rancher-managed resources. If you haven't installed this package yet, you can do so by running `npm install @pulumi/rancher2`.

Below is a Pulumi program that performs the required steps to deploy the `keycloak-configurator` Helm chart using the `rancher2` package.

```typescript
import * as rancher2 from "@pulumi/rancher2";
import * as k8s from "@pulumi/kubernetes";

// Step 1: Initialize the Rancher provider with the appropriate credentials
const rancherProvider = new rancher2.Provider("rancherProvider", {
  // The API URL of the Rancher server.
  apiURL: "https://your-rancher-server-url/v3",
  // Bearer Token to authenticate API requests with the Rancher server.
  bearerToken: "your-rancher-bearer-token",
  // Optional: Specify the cluster ID if you have multiple and you're targeting a specific one.
});

// Step 2: Deploy the keycloak-configurator Helm chart on the cluster
const keycloakConfiguratorChart = new k8s.helm.v3.Chart("keycloak-configurator", {
  chart: "keycloak-configurator",
  version: "chart-version", // replace with the actual chart version
  fetchOpts: {
    repo: "https://repository-containing-chart-url", // replace with the actual chart repository URL
  },
  // Optional: Define values for the Helm chart as needed.
  values: {
    // ...values specific to the keycloak-configurator chart
  },
}, { provider: rancherProvider }); // Bind the Rancher provider to this Helm chart resource

// Export the URL to access the deployed Keycloak instance (assuming it is exposed via a LoadBalancer service)
export const keycloakUrl = keycloakConfiguratorChart.getResourceProperty("v1/Service", "keycloak", "status").apply(status => {
  const ingress = status.loadBalancer.ingress[0];
  if (ingress.hostname) return `http://${ingress.hostname}`;
  return ingress.ip ? `http://${ingress.ip}` : undefined;
});
```

Please replace the placeholder values in the above code with actual values applicable to your environment. For instance, `your-rancher-server-url`, `your-rancher-bearer-token`, `chart-version`, and `repository-containing-chart-url` should be replaced with the URL of your Rancher server, your bearer token for Rancher API access, the version of the `keycloak-configurator` Helm chart, and the URL of the Helm repository that contains the chart, respectively.

Also, make sure you add any specific configuration values that you want to apply to the `keycloak-configurator` chart within the `values` object. The provided example assumes that `keycloak` is deployed with a LoadBalancer, and it exports the URL to access the Keycloak instance after deployment. If your deployment uses a different service type or setup, you will need to adjust the export statement accordingly.

Once the program is ready, you can deploy it using the Pulumi CLI:

```sh
pulumi up
```

Be sure to have your Pulumi stack configured and authenticated with Rancher before you attempt to run the Pulumi application. If you encounter any issues or have questions about your specific setup, please don't hesitate to ask for further guidance.
