Deploy the selfsigned-cert-manager helm chart on Kubernetes

Question

Pulumi · Accepted Answer

To deploy the `self-signed-cert-manager` Helm chart on Kubernetes using Pulumi, you would typically follow these steps:

1. **Set up Your Pulumi Project**: Make sure you have Pulumi installed, and then set up your Pulumi project.
2. **Configure Kubernetes Provider**: Ensure the Pulumi Kubernetes provider is configured to communicate with your Kubernetes cluster.
3. **Specify Helm Release Resource**: Define a Helm Release resource in your Pulumi program, setting the chart name to `selfsigned-cert-manager` and the repository where the Helm chart is located.

Below is a basic Pulumi program in TypeScript that you can use to deploy a `self-signed-cert-manager` Helm chart on a Kubernetes cluster:

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

// Instantiate a Kubernetes provider configured for the target cluster.
const provider = new k8s.Provider("provider", { /* ... */ });

// Deploy the self-signed-cert-manager Helm chart.
const chart = new k8s.helm.v3.Chart("selfsigned-cert-manager", {
    chart: "cert-manager",
    version: "1.0.0", // Specify the chart version you need to use
    namespace: "cert-manager", // Specify the namespace where cert-manager will be installed
    fetchOpts:{
        repo: "https://charts.jetstack.io" // The repository where the cert-manager chart is hosted
    },
    values: {
        // Specify any custom values required for the cert-manager chart.
    },
}, { provider });

// Optionally, you may want to export some of the configuration or resource properties.
export const certManagerChartName = chart.name;
```

Here's what each part of the program does:

- `import * as k8s from "@pulumi/kubernetes";`: Imports the Pulumi Kubernetes SDK.
- `const provider = new k8s.Provider("provider", { /* ... */ });`: Sets up a Kubernetes provider. You would fill in the details based on your specific Kubernetes cluster configuration, such as kubeconfig.
- `const chart = new k8s.helm.v3.Chart("selfsigned-cert-manager", {...}, { provider });`: Defines a Helm chart resource named `selfsigned-cert-manager`. This tells Pulumi to install the `cert-manager` chart from the Jetstack Helm repository with the given version and namespace. You would need to specify the properties and configuration that apply to your Helm release.

The `version` field inside the `Chart` constructor is optional if you wish to use the latest version. Similarly, `namespace` is optional, and if not specified, it defaults to the `default` namespace.

To use this program, you would need to run `pulumi up` in the same directory where this file is to start the deployment. Make sure that you have access rights to the Kubernetes cluster managed by Pulumi and the Helm chart is available in the repository.
