Deploy the axonops helm chart on Rancher

Question

Pulumi · Accepted Answer

To deploy the AxonOps Helm chart on Rancher using Pulumi, you'll need to follow several steps:

1. Set up a Rancher instance and configure it properly for Helm chart deployment.
2. Create a Pulumi project configured to interact with the Rancher API.
3. Write the Pulumi code necessary to deploy the AxonOps Helm chart.

For this process, you will need to utilize the `rancher2` Pulumi provider and the `helm.v3` Pulumi package to deploy Helm charts. First, make sure you have a Rancher instance running and accessible, and that you have the necessary credentials and configuration to interact with its API.

Below, you will find a detailed Pulumi TypeScript program that deploys the AxonOps Helm chart to a Rancher-managed Kubernetes cluster. To use this example, you'll need to replace placeholders like `YOUR_RANCHER_API_URL`, `YOUR_RANCHER_ACCESS_KEY`, `YOUR_RANCHER_SECRET_KEY`, `CLUSTER_ID`, `PROJECT_ID` and `CATALOG_NAME` with your actual Rancher setup details. Additionally, you need to specify the Helm repository that contains AxonOps.

Before we start the code block, please ensure you have installed the `@pulumi/rancher2` and `@pulumi/helm` packages via npm in your development environment.

```typescript
import * as pulumi from "@pulumi/pulumi";
import * as rancher2 from "@pulumi/rancher2";
import * as k8s from "@pulumi/kubernetes";
import * as helm from "@pulumi/helm";

// Initialize Rancher provider configuration with the required access and secret keys for your Rancher environment
const rancherProvider = new rancher2.Provider("rancher", {
    apiUrl: "YOUR_RANCHER_API_URL",
    accessKey: "YOUR_RANCHER_ACCESS_KEY",
    secretKey: "YOUR_RANCHER_SECRET_KEY",
});

// Obtain a reference to the specified Rancher cluster
const cluster = rancher2.getCluster({
    id: "CLUSTER_ID",
}, { provider: rancherProvider });

// Obtain the cluster's Kubernetes provider
const k8sProvider = new k8s.Provider("k8sProvider", {
    kubeconfig: cluster.kubeConfig,
}, { dependsOn: [rancherProvider] });

// Deploy the AxonOps Helm chart to the specified cluster and project within Rancher
const axonopsChart = new helm.v3.Chart("axonops", {
    repo: "axonops-repository", // Make sure to replace this with the actual repository name where the AxonOps chart is located
    chart: "axonops",
    version: "chart-version", // Replace with the specific version you want to deploy, if applicable
    namespace: "axonops", // Specify the namespace where the chart should be deployed, create one if it doesn't exist
    values: {
        // Override default values here if needed
    },
}, { provider: k8sProvider });

// Export the resources
export const axonopsChartResources = axonopsChart.resources;
```

This Pulumi TypeScript program configures the Rancher provider with the necessary API URL and access credentials to interact with your Rancher instance. The program then retrieves the cluster configuration and sets up a Kubernetes provider for it. Finally, the AxonOps Helm chart is deployed to the Rancher-managed Kubernetes cluster using the Helm package, into the namespace `axonops`. You can customize the `values` object to adjust any default settings according to the requirements of your AxonOps deployment.

Keep in mind that in a real-world scenario, it’s best practice to not hardcode sensitive information such as access keys directly in your code. Pulumi supports using configuration or environment variables to safely manage such details.

Remember to replace placeholder values with actual data from your Rancher environment, and ensure you incorporate any specific requirements necessary for your AxonOps Helm chart deployment.

After you've written this code within your Pulumi project, you can deploy the Helm chart by running `pulumi up` in your terminal. This command will provision the resources as defined in your Pulumi program. Ensure you review the preview before confirming to avoid unintended changes.
