Deploy the sso-operator helm chart on Oracle Kubernetes Engine (OKE)

Question

Pulumi · Accepted Answer

To deploy the `sso-operator` helm chart on Oracle Kubernetes Engine (OKE), you will follow these steps:

1. First, you'll need to set up an OKE cluster if you haven't already done so.
2. Ensure you have configuration set up with the necessary access rights to interact with OKE using the `oci` provider.
3. Make sure you have Helm and the Pulumi Kubernetes provider set up locally since you will be using Helm to deploy the `sso-operator`.

We will use two main resources for this task:

- **oci.ContainerEngine.Cluster**: This resource allows you to create an OKE cluster. Documentation for this can be found [here](https://www.pulumi.com/registry/packages/oci/api-docs/containerengine/cluster/).
- **kubernetes.helm.v3.Chart**: After your OKE cluster is running, you can deploy Helm charts into your cluster. The Helm chart resource lets you install, upgrade, and manage applications. Documentation for Helm chart resources can be found [here](https://www.pulumi.com/registry/packages/kubernetes/api-docs/helm/v3/chart/).

Here's the TypeScript program that deploys an `sso-operator` Helm chart to an OKE cluster:

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

// Create an OCI OKE cluster.
const cluster = new oci.containerengine.Cluster("my-cluster", {
    // Replace these attributes with your specific details.
    compartmentId: oci.config.compartmentId,
    vcnId: "YOUR_VCN_ID", // The VCN ID where your OKE cluster will be associated.
    kubernetesVersion: "v1.20.11", // Specify the Kubernetes version.
    options: {
        // Other options like node shape, quantity etc.
        kubernetesNetworkConfig: {
            // Network configuration details.
            podsCidr: "10.1.0.0/16",
            servicesCidr: "10.2.0.0/16"
        },
        // Add-ons such as Tiller or Kubernetes Dashboard are typically enabled here.
        // Add-on options can be left out if not needed.
    },
    // ... additional configuration.
})

// Setup the Kubernetes provider to the OCI OKE cluster.
const provider = new k8s.Provider("oke-k8s", {
    kubeconfig: cluster.kubeconfig, // Use kubeconfig output from the OKE cluster.
});

// Use the Helm Chart resource to deploy the sso-operator.
const ssoOperatorChart = new k8s.helm.v3.Chart("sso-operator", {
    // Replace with the correct chart location and version.
    chart: "sso-operator",
    version: "1.0.0", // Use the appropriate chart version.
    fetchOpts: {
        repo: "https://charts.example.com/", // Helm chart repository URL.
    },
}, { provider }); // Associate with the OKE Kubernetes provider.

// Export the cluster name and kubeconfig.
export const clusterName = cluster.name;
export const kubeConfig = cluster.kubeconfig;
```

### Detailed Explanation

1. We import the necessary Pulumi, OCI, and Kubernetes libraries.
2. We create an instance of an OKE cluster with all necessary configurations like compartment ID, VCN ID, Kubernetes version, and networking configs.
3. We setup a Kubernetes provider using the `kubeconfig` generated during the creation of the OKE cluster. This provider will allow us to interact with the Kubernetes API on the OKE cluster.
4. We define and create a Helm chart resource to deploy the `sso-operator` onto the OKE cluster, specifying the chart name, version, and repository.
5. Lastly, we export some outputs like the cluster name and `kubeconfig` which you could use to interact with your cluster from the command line or other tools.

Please ensure you replace placeholder values with actual values for your OCI configurations such as compartment ID and VCN ID. Also, replace the Helm chart details with the actual chart repository and version you wish to use for the `sso-operator`.
