Deploy the phppgadmin helm chart on Kubernetes

Question

Pulumi · Accepted Answer

To deploy the `phppgadmin` Helm chart on Kubernetes using Pulumi, we will use the `Chart` resource from the Pulumi Kubernetes provider. This resource allows you to deploy Helm charts into your Kubernetes clusters.

Here's a step-by-step program in TypeScript:

1. **Import necessary packages**: We start by importing the required Pulumi and Kubernetes packages.

2. **Create a Kubernetes provider instance** (optional): If you are targeting a specific Kubernetes cluster and your kubeconfig isn't already set up to point to it, you'll need to create a provider instance pointing at the desired cluster.

3. **Deploy the chart using `Chart` resource**: Using the `Chart` resource, we deploy the `phppgadmin` Helm chart from its repository. You must specify the chart name, and optionally, you can provide the chart version, any custom values you want to override in the chart, and the namespace where you want it deployed.

Here is the Pulumi program:

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

// Replace this with the appropriate namespace where you want to deploy phppgadmin
const namespace = "default";

const phppgadminChart = new k8s.helm.v3.Chart("phppgadmin", {
    // You can specify the repo URL where the chart can be found.
    repo: "https://helm-repository-url.com",
    chart: "phppgadmin",
    version: "chart-version", // Specify the chart version you want to deploy
    namespace: namespace,
    // If you want to override values in the chart, specify them here:
    values: {
        // Example of values you might want to override:
        // These are made-up values for illustration purposes; use actual configurable values from the chart
        service: {
            type: "ClusterIP",
            port: 80,
        },
    },
}, { provider: clusterProvider }); // Omit this parameter if you're using the default context in kubeconfig

// Expose an endpoint as a stack export
export const endpoint = phppgadminChart.getResourceProperty("v1/Service", "phppgadmin", "status")
    .apply(status => `http://${status.loadBalancer.ingress[0].hostname}:${status.loadBalancer.port}`);
```

Please adapt the `repo`, `chart`, `version`, and `values` fields to match the actual Helm repository URL and your desired configuration parameters. If you are not running the default configuration, you might need to set up a Kubernetes provider or specify the namespace where you want to deploy the chart.

You can find more documentation on the `Chart` resource [here](https://www.pulumi.com/registry/packages/kubernetes/api-docs/helm/v3/chart/).

Remember to replace the placeholders like the Helm repository URL (`https://helm-repository-url.com`), the chart version (`chart-version`), and any specific values you want to give to the `phppgadmin` chart with the actual ones that fit your use case. The `values` object is a TypeScript object that provides specific configurations for your chart according to its `values.yaml` specification. If you don't need any specific configurations and the defaults are fine, you can omit the `values` property.

The `endpoint` is exported so that you can easily access the `phppgadmin` service once it's deployed. This assumes that your service is of type `LoadBalancer`; if not, you might want to fetch the appropriate service property to form the endpoint URL.
