Deploy the cert-manager-webhook-pdns helm chart on Linode Kubernetes Engine
TypeScriptTo deploy a Helm chart on a Kubernetes cluster using Pulumi, you'll need to use the
@pulumi/kubernetes
package. This package enables you to declare Kubernetes resources using Pulumi's infrastructure-as-code approach. Specifically, we'll use theChart
resource, which allows for Helm chart deployments.In order to deploy the
cert-manager-webhook-pdns
Helm chart on the Linode Kubernetes Engine (LKE), you would generally follow these steps:- Set up your Linode Kubernetes Engine cluster.
- Ensure that you have access to the cluster by configuring
kubectl
. - Use the
@pulumi/kubernetes
package to declare a new Helm chart resource in your Pulumi program.
Here's a program that demonstrates how this can be done using TypeScript. This example assumes that you already have a Kubernetes cluster running on Linode and that your
kubeconfig
file is set up correctly.import * as k8s from "@pulumi/kubernetes"; // Deploy the cert-manager-webhook-pdns Helm chart on your Kubernetes cluster. const certManagerWebhookPdns = new k8s.helm.v3.Chart("cert-manager-webhook-pdns", { chart: "cert-manager-webhook-pdns", version: "INSERT_CHART_VERSION_HERE", // Replace with the specific chart version you wish to deploy fetchOpts: { repo: "INSERT_HELM_REPO_URL_HERE", // Replace with the Helm repository URL that hosts the pdns chart }, // Specify any custom values you wish to pass to the Helm chart. // Replace the 'values' below with your custom configuration. values: { // Example value: specify the image to use for the webhook image: { repository: "YOUR_IMAGE_REPOSITORY", // Replace with your image repository tag: "YOUR_IMAGE_TAG", // Replace with your specific image tag }, // Add other values as needed. }, }); // Export the name of the chart. export const chartName = certManagerWebhookPdns.metadata.apply(m => m.name);
Please remember to replace the placeholders like
INSERT_CHART_VERSION_HERE
,INSERT_HELM_REPO_URL_HERE
,YOUR_IMAGE_REPOSITORY
, andYOUR_IMAGE_TAG
with actual values based on your Helm chart's settings and the particular version ofcert-manager-webhook-pdns
chart you intend to deploy.Keep in mind that deploying custom Helm charts can require additional steps, such as setting up required CRDs (Custom Resource Definitions) ahead of time, or configuring specific permissions within your Kubernetes cluster for cert-manager to function correctly.
After deploying with Pulumi, you can run the Pulumi CLI to apply the changes:
pulumi up
This command will perform the deployment based on the current state of your Pulumi program.
In the event of updates or changes to your Helm chart, you can modify the
values
field in the Pulumi program and rerunpulumi up
to apply the changes.To learn more about using Helm and Kubernetes with Pulumi, you can refer to the official documentation:
