Deploy the stakater-buildah helm chart on Rancher
TypeScriptDeploying a Helm chart on a Rancher-managed Kubernetes cluster involves several steps. Below is a Pulumi program written in TypeScript that you can use as a guide to accomplish this task. This program assumes you have:
- Access to a Rancher-managed Kubernetes cluster.
- The necessary permissions to deploy applications to this cluster.
Here is an outline of the steps we will follow in the Pulumi program:
- Initialize a new Pulumi project with the necessary imports.
- Create a new Kubernetes namespace for the
stakater-buildah
Helm chart (optional but recommended for organization and access control). - Deploy the
stakater-buildah
Helm chart into the Kubernetes namespace created in the previous step.
The Pulumi
@pulumi/rancher2
package can manage Rancher resources. However, the deployment of a Helm chart to a Kubernetes cluster managed by Rancher actually doesn't require specific Rancher components; we'll utilize the standard Kubernetes provider from Pulumi to deploy the Helm chart.Let's get started with the actual Pulumi program:
import * as k8s from '@pulumi/kubernetes'; // Create a new Kubernetes namespace for stakater-buildah const ns = new k8s.core.v1.Namespace("stakater-buildah-ns", { metadata: { // You can specify additional metadata here (e.g., labels, annotations) }, }); // Deploy the stakater-buildah Helm chart const chart = new k8s.helm.v3.Chart("stakater-buildah", { chart: "buildah", version: "1.0.0", // Replace with the actual chart version namespace: ns.metadata.name, fetchOpts:{ repo: "https://stakater.github.io/stakater-charts/", // Helm chart repository URL }, // You can add chart values here to configure stakater-buildah values: { // Example: // replicaCount: 2, }, }, { dependsOn: [ns] }); // Ensure the namespace is created before the chart // Export the base URL of the stakater-buildah service export const buildahUrl = chart.getResourceProperty("v1/Service", "stakater-buildah", "status").apply(status => { return status.loadBalancer.ingress[0].ip; // This line depends on your service type and might need adjustment });
This program does the following:
- Imports the Kubernetes package from Pulumi which is used to interact with Kubernetes resources.
- Declares a new Kubernetes namespace resource for organizational purposes.
- Deploys the
stakater-buildah
Helm chart into the specified namespace. It specifies the chart name, version, and the repository where the chart can be found. - Exports the URL of the deployed service if it's accessible through a LoadBalancer. Note that this assumes a LoadBalancer service type, you might need to adjust if your service type is different (like ClusterIP or NodePort).
To run this Pulumi program:
- Ensure Pulumi and the required cloud CLI (in this case, Rancher CLI,
kubectl
for Kubernetes) are installed and configured on your machine. - Create a new Pulumi TypeScript project if you haven't already (
pulumi new typescript
). - Place the above code into the
index.ts
file within your Pulumi project. - Run
pulumi up
to preview and deploy the resources.
Remember to replace the Helm chart version with the version you want to deploy. Also, if
stakater-buildah
requires specific customization, you should provide these values in thevalues
field of the Helm chart resource. The exportedbuildahUrl
at the end is to access the deployed application; it may require adjustments based on your exact service setup.
