Deploy the sftp-gcs helm chart on Opensshift

Question

Pulumi · Accepted Answer

To deploy a Helm chart on OpenShift, you will need to use the `kubernetes.helm.v3.Chart` resource from Pulumi's Kubernetes provider. The Helm chart for deploying an SFTP server that uses Google Cloud Storage (GCS) as a backend storage (if one exists) would generally be found in a Helm repository.

Before you begin, you should have the following prerequisites:
- An OpenShift cluster where you have `admin` access.
- `kubectl` configured to interact with your OpenShift cluster.
- Pulumi CLI installed and authenticated to your chosen state backend.
- A Helm chart for SFTP-GCS or an equivalent containerized solution.

Below is a Pulumi program that demonstrates how to deploy a Helm chart on an OpenShift cluster using TypeScript. Note that the specific details of the `sftp-gcs` Helm chart, such as repository URL, chart name, values, and versions, would need to be provided, and you would replace the placeholders in the code with the actual values. The namespace where the Helm chart will be installed also needs to be specified.

Assuming you have the necessary Helm chart details, here's how you could write the Pulumi program in TypeScript:

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

// Define the settings of the Helm chart for your SFTP-GCS deployment.
const sftpGcsChart = new k8s.helm.v3.Chart("sftp-gcs-helm-chart", {
    chart: "sftp-gcs", // Replace with the actual chart name.
    version: "1.0.0", // Specify the version of the chart.
    fetchOpts: {
        repo: "https://your-helm-repo-here/", // Specify the Helm repository URL where the chart is hosted.
    },
    namespace: "default", // Replace with the namespace where you want to deploy your SFTP-GCS service.
    values: {
        // Define any values to customize the deployment.
        // For example:
        // storage: {
        //     gcs: {
        //         bucketName: "my-sftp-bucket"
        //     }
        // }
        // Refer to the chart's values for accurate configuration options.
    },
}, { 
    provider: new k8s.Provider("openshift-provider", {
        // If needed, configure the provider for your specific OpenShift cluster.
        // Note that if your `kubectl` is already configured to communicate with your OpenShift cluster,
        // then the provider configuration might not be necessary.
    }),
});

// Export any relevant outputs that may be useful.
export const sftpServiceIp = sftpGcsChart.getResourceProperty("v1/Service", "sftp-gcs-service", "status").apply(status => status.loadBalancer.ingress[0].ip);
```

This program initializes a `Chart` resource which represents the SFTP-GCS chart being deployed to your OpenShift cluster. Pulumi understands the Helm chart semantics and deploys it to the cluster in the same way that Helm would, but with the added benefits of infrastructure as code practices.

The `values` object should be configured according to the Helm chart's custom settings which are relevant to the SFTP-GCS functionality. These settings determine things like the Google Cloud Storage bucket name, authentication parameters, and other important operational parameters for your SFTP service.

The `Provider` object is optional and depends on your OpenShift cluster. If your local `kubectl` context is pointing to the OpenShift cluster and is configured correctly, Pulumi will use it by default.

Lastly, the `export` statement allows you to output the IP address of the SFTP service once it has been deployed. This can be useful for configuring DNS or setting up clients to connect to the SFTP server.

Remember to replace placeholder comments like `// Replace with...` with actual values related to your specific deployment.
