Deploy the openunison-k8s-login-saml2 helm chart on Kubernetes

Question

Pulumi · Accepted Answer

To deploy the `openunison-k8s-login-saml2` helm chart on Kubernetes using Pulumi, we will use the `helm.v3.Chart` resource from the Pulumi Kubernetes provider. This resource allows us to deploy Helm charts into a Kubernetes cluster.

In the Pulumi program below, we first import the necessary packages. Then, we instantiate a `Chart` resource, specifying the chart we want to deploy, which is `openunison-k8s-login-saml2`. The `repo` field specifies the Helm chart repository, the `chart` field specifies the name of the chart, and the `values` field is a JavaScript object that represents any configuration options you want to customize for your deployment. You will need to replace `YOUR_VALUES_HERE` with any specific values you wish to set for the Helm chart, based on the `openunison-k8s-login-saml2` chart's documentation.

Here is an example TypeScript program to deploy `openunison-k8s-login-saml2`:

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

// Deploying the `openunison-k8s-login-saml2` Helm chart into the `default` namespace.
// Replace `YOUR_REPO_URL_HERE` with the URL of the repository that contains the chart and
// populate `YOUR_VALUES_HERE` with the actual configuration for your deployment.

const openunisonChart = new k8s.helm.v3.Chart("openunison-login-saml2", {
    // Define the Helm chart repository and chart name
    chart: "openunison-k8s-login-saml2",
    // Uncomment and adjust the following line if the Helm chart is hosted in a custom repository
    // repo: "YOUR_REPO_URL_HERE",
    version: "1.0.0",  // Set the version of the chart to deploy
    namespace: "default",  // Namespace to deploy the Helm chart into
    values: {
        // Customized values for the `openunison-k8s-login-saml2` Helm chart
        // Replace `YOUR_VALUES_HERE` with your specific configuration
        // Example configuration could be the SAML2 metadata URL, entity ID, etc.
        // metadataUrl: "https://idp.example.com/metadata",
        // entityID: "openunison-on-k8s",
    },
});

// To access or export any properties from the Helm chart deployment, you can use the following:
export const openunisonChartName = openunisonChart.getResourceProperty("v1/Service", "openunison", "metadata").apply(m => m.name);
```

This program sets up a Helm chart deployment for `openunison-k8s-login-saml2`.
- The `Chart` resource is the Pulumi representation of a Helm chart deployment.
- The `values` field should be populated with the specific configuration of your Helm chart as per its documentation or default values file (often found in the chart's repository or in its packaged contents).

Please adjust the `version` and add the `repo` parameters as needed, depending on the version of the chart you wish to use and where it is located (if it is not part of the public Helm chart repositories).

After writing this Pulumi program, you can deploy it using the Pulumi CLI:
1. Initialize a new Pulumi project using the CLI, if you haven't done so already.
2. Save this code to a file named `index.ts` in your Pulumi project directory.
3. Run `pulumi up` to preview and deploy the resources defined in your program.

Make sure that you have the Pulumi CLI installed and configured for access to your Kubernetes cluster. Pulumi uses your local Kubernetes config file to interact with your cluster, so ensure that the `kubectl` command-line tool is also configured correctly.
