Deploy the openshift-oauth-proxy helm chart on Kubernetes

Question

Pulumi · Accepted Answer

To deploy the `openshift-oauth-proxy` Helm chart on a Kubernetes cluster using Pulumi, you can use the `@pulumi/kubernetes` package, which provides the necessary resources to work with Kubernetes. The specific resource you'll be using from this package is the `Chart` resource, which allows you to deploy a Helm chart from within your Pulumi program.

Here is how you can achieve the deployment:

1. **Install the `@pulumi/kubernetes` npm package**: Make sure that you have this package installed in your project to work with Kubernetes resources.

2. **Find the `openshift-oauth-proxy` Helm chart**: You would need to know the Helm repository where the `openshift-oauth-proxy` Helm chart is located. If this is a public chart, it may be available on a known repository, or it might be hosted on a private chart repository that you have to add.

3. **Write the Pulumi program**: Use the `Chart` resource to specify the chart name, version, and any values that are required to configure the proxy.

4. **Deploy with Pulumi**: You run `pulumi up` to deploy the chart on your Kubernetes cluster.

Below is a TypeScript program that illustrates these steps. This example assumes that the `openshift-oauth-proxy` Helm chart is available in a public repository and does not require any specific configuration values. If your actual Helm chart requires configuration values, you should include those in the `values` property of the `Chart` resource.

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

// Create a Pulumi Kubernetes provider by using the current context of `kubectl`.
// This is the cluster where you want to deploy the `openshift-oauth-proxy`.
const provider = new k8s.Provider("k8s-provider", {
  // You can specify the context if you need to target a specific Kubernetes cluster
  // context: "my-cluster-context",
});

// Deploy the `openshift-oauth-proxy` Helm chart using the `Chart` resource.
const openshiftOauthProxyChart = new k8s.helm.v3.Chart("openshift-oauth-proxy-chart", {
  // Specify the Helm chart repository details.
  // Replace `chartRepoUrl` with the actual Helm repository URL where the OpenShift OAuth Proxy chart is hosted.
  repo: "my-helm-chart-repo",
  chart: "openshift-oauth-proxy",
  // Specify the version of the chart if required.
  // version: "1.1.0",
  // Define any values that the chart accepts for configuration.
  // values: {
  //    key: "value",
  // },
}, { provider });

// Export the deployment details if needed. For example, you can export the chart's status.
export const deploymentStatus = openshiftOauthProxyChart.status;
```

Please modify the `repo` property with the correct repository URL where the `openshift-oauth-proxy` Helm chart is located. Also, set the correct version in the `version` property if you need to deploy a specific chart version.

Once you have this Pulumi program ready, you can run `pulumi up` from your terminal, and Pulumi will handle the deployment to your Kubernetes cluster. The `export` statement in the code above is optional, but it can be useful if you want Pulumi to output specific deployment information after the process is complete.

Remember to also manage Helm repositories, if necessary, using Helm CLI commands such as `helm repo add` to add the repository that contains your Helm chart.
