Deploy the zimagi helm chart on Rancher

Question

Pulumi · Accepted Answer

To deploy a Helm chart on a Kubernetes cluster managed by Rancher using Pulumi, you would typically follow these steps:

1. **Set up your Rancher cluster**: Ensure you have a Rancher Kubernetes cluster up and running. You would need appropriate access credentials such as a kubeconfig file to interact with your Kubernetes cluster through Rancher.

2. **Use the Pulumi Kubernetes Provider**: Pulumi's Kubernetes provider allows you to interact with your Kubernetes cluster, managing resources like namespaces, deployments, and services.

3. **Create a Pulumi program to deploy the Helm chart**: Write a Pulumi program that uses the Kubernetes provider to deploy the Helm chart into the cluster.

4. **Run the Pulumi program**: Execute your Pulumi program to deploy the Helm chart onto your Rancher-managed Kubernetes cluster.

Here is a TypeScript program that uses Pulumi to deploy the "zimagi" Helm chart onto a Kubernetes cluster.

First, make sure you have Pulumi installed and have access to your Rancher Kubernetes cluster. Additionally, ensure you have fulfilled any Helm chart-specific requirements like creating necessary namespaces or pre-configuring any dependencies.

The program involves:

- Creating a new `helm.v3.Chart` resource, which represents the Helm chart you wish to install. In this case, the chart is named "zimagi".
- Configuring the chart options like repository URL, version, and any custom settings required by the chart.
- Optionally, setting up a `kubernetes.Provider` if you want to manage multiple clusters or need specific configurations for the provider.

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

// If you are using a dedicated kubeconfig for your Rancher cluster, uncomment the following
// lines and specify the path to your kubeconfig file.
// Otherwise, the program will use the default kubeconfig context.
//
// const rancherKubeconfig = "<PATH_TO_YOUR_KUBECONFIG>";
//
// const rancherProvider = new kubernetes.Provider("rancherProvider", {
//     kubeconfig: rancherKubeconfig
// });

// Deploying the zimagi Helm chart into the default namespace.
// Customize the settings below according to your Helm chart requirements.
const zimagiChart = new kubernetes.helm.v3.Chart("zimagi", {
    // Replace the `repo` URL with the actual repository containing the zimagi chart,
    // and specify the correct `version` as needed.
    chart: "zimagi",
    version: "1.0.0", // Replace with actual chart version
    fetchOpts: {
        repo: "http://charts.zimagi.com/", // Use the appropriate chart repository
    },
    // Any custom values for the zimagi chart can be placed in the `values` object.
    values: {
        // placeholder for zimagi chart values
    },
    // Uncomment the line below and specify the `rancherProvider` if required.
    // provider: rancherProvider,
}, { /* provider: rancherProvider */ });

// Export the name of the chart that was deployed
export const chartName = zimagiChart.metadata.name;
```

When you run this program with `pulumi up`, it will interact with your Kubernetes cluster managed by Rancher and deploy the "zimagi" Helm chart.

Remember to customize the chart repository (`fetchOpts.repo`), chart version (`version`), and any configuration values (`values`) to match the specifics of the "zimagi" Helm chart and your requirements. The commented parts in the program are there to guide you in case you need a specific kubeconfig or want to use a non-default provider for your cluster.
