Deploy the github-authorized-keys helm chart on Rancher
TypeScriptTo deploy the
github-authorized-keys
Helm chart on a Rancher-managed Kubernetes cluster using Pulumi, we will use therancher2
Pulumi provider. Therancher2
provider allows us to interact with Rancher 2.x features programmatically. We will perform the following steps:- Import needed packages.
- Instantiate the Rancher provider.
- Deploy the Helm chart on the cluster.
First, we will need to import the
@pulumi/rancher2
package, which provides the necessary resources for interacting with Rancher 2.x.Here is a high-level Pulumi TypeScript program that demonstrates how you would use Pulumi to deploy a Helm chart to a Rancher 2.x cluster:
import * as pulumi from "@pulumi/pulumi"; import * as rancher2 from "@pulumi/rancher2"; import * as kubernetes from "@pulumi/kubernetes"; // Initialize the Rancher provider configuration. // Assuming you have already configured the necessary Rancher API endpoint, access key, and secret key. const rancherProvider = new rancher2.Provider("provider", { // The API URL for your Rancher instance, could also be set in the environment variable `RANCHER_URL` apiUrl: "https://your-rancher-api-url", // Rancher Access Key, could also be set in the environment variable `RANCHER_ACCESS_KEY` accessKey: "your-rancher-access-key", // Rancher Secret Key, could also be set in the environment variable `RANCHER_SECRET_KEY` secretKey: "your-rancher-secret-key", }); // Instantiate the Kubernetes provider using the Rancher Kubeconfig. // The kubeconfig can be generated within the Rancher UI or via the Rancher API. const k8sProvider = new kubernetes.Provider("k8s-provider", { kubeconfig: rancherProvider.kubeconfig.apply(config => config), }); // Deploy the `github-authorized-keys` Helm chart. const chart = new kubernetes.helm.v3.Chart("github-authorized-keys", { chart: "github-authorized-keys", version: "chart-version", // Replace with the chart version you intend to deploy // Assuming that the chart repository has been added to Helm within Rancher or to your local Helm configuration repo: "chart-repo-name", // Replace with the name of the chart repository // Optionally specify the namespace and values for the deployment namespace: "default", // Replace with the namespace where you want the chart to be deployed values: { // Add any specific configuration values here // For example: // repository: "https://github.com/your-username", // authorizedUsers: ["user1", "user2"], }, }, { provider: k8sProvider }); // Export the chart's name and version. export const chartName = chart.chart; export const chartVersion = chart.version;
In this program:
- We import the required Pulumi packages.
- We configure the Rancher provider, providing API access to Rancher.
- We configure the Kubernetes provider using Rancher's kubeconfig to interact with the underlying Kubernetes cluster managed by Rancher.
- We deploy the
github-authorized-keys
Helm chart using Pulumi'skubernetes.helm.v3.Chart
resource, specifying the chart name, version, repository, and any custom values required for the chart. - We export the name and version of the deployed chart for easy access to this information after deployment.
Remember to replace the placeholders (such as
your-rancher-api-url
,your-rancher-access-key
,chart-version
, etc.) with your actual Rancher API endpoint, credentials, and Helm chart details.Please note that you'll need to have access to a Rancher 2.x cluster with API keys, and the
github-authorized-keys
Helm chart should be available in your configured Helm repository. If these prerequisites are not met, the above program will not work as expected.To run this program, you'll need to set up Pulumi and authenticate with your Rancher instance. You can then run
pulumi up
to create the resources defined in the program. If you'd like a more in-depth guide on how to set up Pulumi with Rancher, you can find resources in the Pulumi Documentation.
