Deploy the keycloak-resources deployment for keycloak-operator helm chart on Digital Ocean Kubernetes Service

Question

Pulumi · Accepted Answer

To deploy a `keycloak-resources` deployment using the `keycloak-operator` Helm chart on Digital Ocean Kubernetes Service (DOKS), you will need to complete a few steps. The process includes setting up a Digital Ocean Kubernetes Cluster and installing the `keycloak-operator` through the Helm package manager for Kubernetes.

The following program in TypeScript uses Pulumi to achieve your goal:

1. Set up a Digital Ocean Kubernetes cluster using the `digitalocean.KubernetesCluster` resource.
2. Use the `kubernetes.helm.v3.Chart` resource from the Pulumi Kubernetes provider to deploy the `keycloak-operator` Helm chart into the Kubernetes cluster.

Before you begin, make sure you have the Pulumi CLI installed and configured for Digital Ocean and Kubernetes. Also, make sure you have Helm installed if you want to inspect or customize the chart values locally.

Now, let's dive into the Pulumi program:

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

// Create a DigitalOcean Kubernetes cluster
const cluster = new digitalocean.KubernetesCluster("do-cluster", {
    region: digitalocean.Regions.NYC1,
    version: "latest",
    nodePool: {
        name: "default",
        size: digitalocean.DropletSlugs.DropletS2VCPU2GB,
        nodeCount: 2,
    },
});

// Create a provider for the DigitalOcean Kubernetes cluster
const k8sProvider = new k8s.Provider("do-k8s-provider", {
    kubeconfig: cluster.kubeConfigs[0].rawConfig,
});

// Deploy the keycloak-operator helm chart
const keycloakOperatorChart = new k8s.helm.v3.Chart("keycloak-operator", {
    chart: "keycloak-operator",
    version: "latest", // Specify the version of the keycloak-operator chart you wish to deploy
    namespace: "default",
}, { provider: k8sProvider });

// Export the cluster's kubeconfig and the Keycloak operator chart's status
export const kubeconfig = cluster.kubeConfigs[0].rawConfig;
export const keycloakOperatorChartStatus = keycloakOperatorChart.status;
```

Here's what each part of the program is doing:

- The `digitalocean.KubernetesCluster` resource is creating a new Kubernetes cluster in your Digital Ocean account. You can customize the region, version, and node pool as necessary for your use case.
- The `k8s.Provider` resource establishes the connection to your newly created Kubernetes cluster.
- The `k8s.helm.v3.Chart` resource deploys the `keycloak-operator` Helm chart using the specified version. If needed, you can include additional Helm values to further configure your deployment.

Lastly, we have two lines exporting the cluster's kubeconfig and the Keycloak operator chart's status. This allows you to easily access your cluster with `kubectl` and check on the status of your Helm release from the Pulumi stack's outputs.

To run this program, save it to a file with a `.ts` extension, such as `index.ts`, and then execute the following commands in your terminal:

```sh
pulumi stack init dev
pulumi up
```

After confirming the changes in your terminal, Pulumi will provision the DOKS cluster and the keycloak-operator Helm chart according to your configuration.
