Deploy the keycloak-db-storage helm chart on Rancher

Question

Pulumi · Accepted Answer

To deploy a Helm chart on a Rancher-managed Kubernetes cluster using Pulumi, you would typically need to perform the following steps:

1. Set up Pulumi with the appropriate provider for Rancher (in this case, the `rancher2` provider).
2. Use Pulumi to communicate with Rancher to either select an existing Kubernetes cluster or create a new one.
3. Apply the Helm chart to the selected or newly created cluster.

Below is a program that demonstrates how to deploy the `keycloak-db-storage` Helm chart to a Rancher-managed cluster using Pulumi and TypeScript. Note that this code assumes that you have already set up and authenticated Pulumi with your Rancher instance.

The `rancher2.AppV2` resource is used to deploy a Helm chart within a Rancher project on a specific cluster. The `namespace`, `name`, and `chart` properties define where and what Helm chart will be deployed. Make sure to replace `your-rancher-project-id` with the project ID from your Rancher environment, and update the chart's `repo` and `version` to match the `keycloak-db-storage` Helm chart details you wish to deploy.

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

const chartName = "keycloak-db-storage";
const projectName = "your-rancher-project-id";
const chartRepoUrl = "https://charts.example.com/";
const chartVersion = "1.0.0"; // replace with the specific chart version you want to deploy

// Deploying the chart as an App within a Rancher managed cluster
const keycloakDbStorageApp = new rancher2.AppV2(chartName, {
    // Replace with the ID of your Rancher project
    projectId: projectName,
    // The name of the namespace in the cluster where the app will be deployed
    namespace: "keycloak",
    // The name to give the app
    name: chartName,
    // The repository which contains the chart
    repoName: chartRepoUrl,
    // The Helm chart to deploy
    chart: chartName,
    // Specify the version of the chart to deploy
    version: chartVersion,
    // Add any values here which you want to override the default chart values
    values: {
        key: "value", // Example, replace with actual values
        // ...
    }
});

export const appStatus = keycloakDbStorageApp.status;
```

Please note the following:

- The `values` field inside the `rancher2.AppV2` resource allows you to specify any chart-specific configurations. You would substitute the example `key: "value"` with the actual values you need for your `keycloak-db-storage` Helm chart deployment.
  
- `"keycloak"` is the namespace where the application will be deployed, which you might need to replace with the namespace you prefer or you're meant to use.

- `appStatus` is exported to provide an easy way to query the application deployment status from Pulumi after deployment.

Remember, this program assumes that you have the appropriate permissions and that the project and the cluster are already set up within Rancher. If you don't have a cluster yet, you would need to create one using the `rancher2.Cluster` resource before deploying the Helm chart.

Before running this program, ensure you have the Rancher provider configured for Pulumi. You would typically set the required configuration values for the Rancher provider, such as access keys or passwords, through environment variables or the Pulumi secrets manager.

Once your Pulumi program is ready, deploy it by running `pulumi up` in the CLI where this TypeScript program is saved. Pulumi will prompt you with a preview of the actions to be performed and, upon your approval, will proceed with the deployment. Upon success, Pulumi will report the resources created, and you can verify the deployment directly in your Rancher UI.

For more detailed information on using the Rancher provider with Pulumi, you can refer to the [Pulumi Rancher2 documentation](https://www.pulumi.com/registry/packages/rancher2/).
