Deploy the secrets helm chart on Opensshift

Question

Pulumi · Accepted Answer

To deploy a Helm chart on an OpenShift cluster using Pulumi, you would typically perform the following steps:

1. **Set Up Pulumi Kubernetes Provider**: Set up the Pulumi Kubernetes provider to connect to your OpenShift cluster.
2. **Create a Kubernetes Secret (if required)**: If your Helm chart requires any secrets, you'll create them using Kubernetes API objects in Pulumi.
3. **Deploy the Helm Chart**: Use the Pulumi Kubernetes provider to deploy the Helm chart onto your cluster.

Below is a Pulumi TypeScript program that achieves these steps. Remember to have your `kubeconfig` file properly configured for accessing your OpenShift cluster as Pulumi will use it to interact with the cluster.

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

// Assuming your kubeconfig is set up, Pulumi uses the context from the kubeconfig file.
// No need for explicit configuration if `kubeconfig` is properly set.
const provider = new k8s.Provider("openshift-provider", {
  // Optionally specify the kubeconfig context to use.
  // context: "your-openshift-context"
});

// If your Helm chart needs a secret, you would create it like this:
const mySecret = new k8s.core.v1.Secret("my-secret", {
  metadata: { 
    name: "my-secret"
  },
  type: "Opaque", // Or the appropriate type for your needs
  stringData: {
    "key": "value", // Replace with your secret's key-value pairs
    // More key-value pairs as needed
  },
}, { provider });

// Deploy your Helm chart to the OpenShift cluster
const myChart = new k8s.helm.sh.v3.Chart("secrets-chart", {
  chart: "secrets", // The name of the chart, change if your chart is named differently
  version: "1.0.0", // The version of the chart to deploy
  namespace: "default", // The namespace where the chart should be deployed, change as needed
  values: { // Values to override in the Helm chart
    // Insert overrides like `key: value` here if your chart requires them
  },
  // Reference the secret if needed like below:
  // These are dummy values, replace with actual values if your chart needs them
  fetchOpts: {
    repo: "https://charts.helm.sh/stable", // The actual repo of your chart
  },
}, { provider, dependsOn: mySecret });

// Export the Chart's status
export const chartStatus = myChart.status;
```

In this program, I've:

1. **Defined a Kubernetes Provider**: The provider is configured to manage resources in our OpenShift cluster using the `kubeconfig` context (this can be omitted if Pulumi should use the default context).
   
2. **Created a Kubernetes Secret**: If required by the Helm chart. This includes stating its name, type, and actual data contents, which are supposed to be sensitive and not committed to source control.

3. **Deployed the Helm Chart**: I've instantiated a Helm chart using the `k8s.helm.sh/v3.Chart` class. You must replace `"secrets"` with the actual name of your Helm chart and similarly, use the correct `version`, `namespace`, `values`, and the Helm repository URL in `fetchOpts.repo`.

Remember that Helm and the chart repository must be properly set up and accessible from your OpenShift cluster. For a chart that requires access to private images or repositories, you should also configure the appropriate secrets or credentials within your OpenShift cluster.

Finally, I've exported the chart status so you can retrieve information about the deployment using the `pulumi stack output chartStatus` command after deployment.
