Deploy the tyk-dashboard helm chart on Linode Kubernetes Engine
TypeScriptTo deploy the Tyk Dashboard Helm chart on Linode Kubernetes Engine (LKE), you'll primarily use the
kubernetes.helm.sh/v3.Chart
resource from the Pulumi Kubernetes provider. This resource allows you to deploy Helm charts in a Kubernetes cluster managed by Pulumi. In this context, we're assuming that you have a Kubernetes cluster running on Linode and that you have configuredkubectl
and Pulumi to communicate with it.The
kubernetes.helm.sh/v3.Chart
resource requires several properties such aschart
,version
, andvalues
, which specify the Helm chart details you wish to deploy. You might also need to set therepo
property if your Helm chart is hosted on a custom Helm repository.Below is a program written in TypeScript that can be used to deploy the Tyk Dashboard on an LKE cluster. Before running the program, ensure you have the Pulumi CLI installed and configured to use with the Kubernetes cluster you have on Linode.
Detailed Explanation
-
Kubernetes Cluster Configuration: The program assumes you have an LKE cluster. You must have
kubeconfig
set up to allow communication with your cluster. Pulumi uses this configuration to deploy resources to your Kubernetes cluster. -
Pulumi Kubernetes Provider: This program uses the Pulumi Kubernetes provider to interact with your Kubernetes cluster and deploy the Tyk Dashboard Helm chart.
-
Helm Chart Deployment: The core of the program is the
kubernetes.helm.sh/v3.Chart
resource, which encapsulates the Helm chart deployment. It specifies the chart name, repository, and potentially other configurations such as customvalues
which can be provided to customize the deployment.chart
: The name of the chart in the repository.version
: The version of the Helm chart to deploy. If not specified, the latest version will be deployed.repo
: The Helm chart's repository URL. If the Tyk Dashboard chart is available on the default Helm repository, this field is optional.
-
Helm Values: You can provide a set of key-value pairs to customize the Helm chart deployment. For the Tyk Dashboard, you might need to specify configuration properties like the Tyk license key, public URLs, etc.
Now, let's look at the Pulumi program code:
import * as pulumi from "@pulumi/pulumi"; import * as kubernetes from "@pulumi/kubernetes"; // Define the Helm chart repository for Tyk Dashboard. const tykRepo = "https://helm.tyk.io/public/helm/charts/"; const tykChartVersion = "x.y.z"; // Replace with the specific version you want to deploy // Define the Tyk Dashboard Helm chart deployment. const tykDashboardChart = new kubernetes.helm.v3.Chart("tyk-dashboard", { chart: "tyk-headless", version: tykChartVersion, fetchOpts: { repo: tykRepo, }, values: { // You can specify custom values for your Helm chart here. // This is an example of how you might specify the portal configuration. "portal": { "enabled": true, "hostnames": ["your-portal-hostname.com"], }, // Make sure to configure other required values like Tyk API credentials, // URLs, storage options, or any other configurations needed for the Tyk Dashboard. }, }, { provider: clusterProvider }); // Ensure you have a Kubernetes provider configured to interact with your LKE cluster. // Export the URL of the Tyk Dashboard service once it's ready. export const tykDashboardUrl = tykDashboardChart.getResourceProperty("v1/Service", "tyk-dashboard", "status") .apply(status => status.loadBalancer.ingress[0].hostname ?? status.loadBalancer.ingress[0].ip);
How to Run the Program
- Install Pulumi: Ensure you have the Pulumi CLI installed.
- Set up Access: Configure Pulumi to access your Linode Kubernetes cluster. Follow the Linode guide to set up
kubeconfig
. - Create a new directory for your Pulumi project and navigate into it.
- Run
pulumi new typescript
to create a new Pulumi TypeScript project. - Replace the content of
index.ts
with the code above. - Run
npm install @pulumi/pulumi @pulumi/kubernetes
to install the necessary dependencies. - Run
pulumi up
to preview and deploy the changes. Confirm the deployment by selecting 'yes'.
If you don't have the Tyk Dashboard chart in a custom repository and it's available in the default Helm repository, you can remove the
repo
field offetchOpts
. Ensure you replacex.y.z
with the actual chart version and potentially replace any example values with actual configuration values needed for the Tyk Dashboard.Please refer to the Tyk Dashboard Helm Chart documentation for the details of the configurations required for deployment.
