Deploy the bind9 helm chart on Rancher

Question

Pulumi · Accepted Answer

To deploy a bind9 Helm chart on Rancher using Pulumi, we will follow these steps:

Setup the Rancher2 provider.
Create a CatalogV2 resource which adds the Helm chart repository that contains the bind9 chart to Rancher.
Deploy the bind9 chart using the AppV2 resource which represents a Helm chart deployment.

First, you will need to have access credentials for Rancher and a Kubernetes cluster managed by Rancher.

We'll be using the rancher2 Pulumi package to interact with your Rancher instance. The CatalogV2 resource is used to add a new Helm chart repository to the Rancher cluster. Then, we'll use the AppV2 resource to deploy an application from the Helm chart repository that we've just added.

Here is how you can create a Pulumi program in TypeScript that deploys the bind9 Helm chart on Rancher:

import * as rancher2 from "@pulumi/rancher2";

// Replace these variables with appropriate values
const rancherApiUrl = "https://<RANCHER_API_URL>";
const rancherAccessToken = "<RANCHER_ACCESS_TOKEN>";
const rancherClusterId = "<RANCHER_CLUSTER_ID>";
const catalogName = "bind9-catalog";
const appName = "bind9-app";
const chartName = "bind9";
const chartVersion = "<BIND9_CHART_VERSION>"; // Specify the version of the chart you want to deploy
const namespaceName = "bind9-namespace";

// Set up the Rancher2 provider
const rancherProvider = new rancher2.Provider("rancher", {
    apiUrl: rancherApiUrl,
    tokenKey: rancherAccessToken,
});

// Create a new catalog (Helm chart repository) within Rancher
const catalog = new rancher2.CatalogV2(catalogName, {
    url: "https://charts.bitnami.com/bitnami", // Replace with the URL of the repo containing bind9
    clusterId: rancherClusterId,
}, { provider: rancherProvider });

// Deploy the bind9 Helm chart as an application within Rancher
const app = new rancher2.AppV2(appName, {
    repoName: catalogName,
    chartName: chartName,
    chartVersion: chartVersion,
    namespace: namespaceName,
    clusterId: rancherClusterId,
    values: ``, // Provide custom values for your bind9 deployment if needed
}, { provider: rancherProvider, dependsOn: [catalog] });

// Export the app name and version
export const appNameOutput = app.name;
export const appVersionOutput = app.status.apply(status => status?.version);

Before you execute this code with Pulumi, replace placeholder values with the actual values for your Rancher API URL, access token, cluster ID, and the version of the bind9 chart you want to deploy.

To run this Pulumi program:

Save the code to a file named index.ts.
Initialize a new Pulumi project in the same directory as your index.ts file:

pulumi new typescript
Install the necessary dependencies by running:

npm install @pulumi/rancher2
Run pulumi up to create the resources.

When you execute pulumi up, Pulumi will communicate with Rancher to set up the Helm chart repository and deploy the bind9 chart on your Kubernetes cluster managed by Rancher.

Please note that you would need to replace <BIND9_CHART_VERSION> with the actual version of the Helm chart you wish to deploy. You can typically find this in the Helm repository or on an artifact hub that lists versions of Helm charts.

The values property in the AppV2 resource should contain configuration values for your bind9 deployment. Typically these values are provided as a YAML or JSON string that customizes the deployment to your needs.

Remember to manage sensitive information such as tokens and API URLs securely, for instance using Pulumi secrets.
