Deploy the easegress helm chart on Kubernetes
TypeScriptTo deploy the Easegress Helm chart on Kubernetes using Pulumi, you need to create a Pulumi program that uses the
Chart
resource from the Pulumi Kubernetes provider. Helm charts are a way to package applications for Kubernetes, and Pulumi can manage these applications directly using the Helm chart as a resource in your Pulumi code.Here's a step-by-step explanation followed by a Pulumi TypeScript program that deploys the Easegress Helm chart:
- Setting up the Pulumi Program: Start by creating a new directory, initializing a new Pulumi project, and installing necessary dependencies.
- Creating the Kubernetes Cluster: You must have access to a Kubernetes cluster. For simplicity, this example assumes that you have already configured
kubectl
to point to your cluster. - Adding Pulumi Kubernetes Provider: This provider allows Pulumi to interact with Kubernetes resources.
- Defining the Helm Chart Resource: You specify the Easegress Helm chart using the
Chart
resource. You can customize it by specifyingvalues
(which override default values in the chart), chart version, and release name.
Below is the TypeScript program for deploying the Easegress Helm chart on Kubernetes:
import * as k8s from '@pulumi/kubernetes'; // Step 1: Create a new Chart resource. `kubernetes.helm.sh/v3.Chart` represents a Helm chart. const easegressChart = new k8s.helm.sh.v3.Chart("easegress", { // Specify parameters for the Helm chart: chart: "easegress", // The name of the chart. Replace with the correct Helm chart name. version: "1.0.0", // The version of the chart. Replace with the desired version. fetchOpts: { repo: "https://helm_repo_url_here", // The repository URL where the chart is located. Replace with the actual URL. }, // Define values to override the default chart values. values: { service: { type: "LoadBalancer", }, // Add other values here as needed for customizing the Easegress deployment. }, }, { provider: k8sProvider, // Use `k8sProvider` if you are working with a specific Kubernetes provider instance. }); // Export the public IP address of the LoadBalancer associated with the Easegress service. export const easegressPublicIp = easegressChart.getResourceProperty("v1/Service", "easegress", "status") .then(status => status.loadBalancer.ingress[0].ip);
Please replace the
chart
,version
, andrepo
fields with the actual values for the Easegress Helm chart you want to deploy. If it's publicly available on a well-known chart repository like Bitnami or stable Helm chart repos, you might not need to specify therepo
field. You can also customize thevalues
object with your configuration values that are specific to Easegress.Once you have this code set up, run
pulumi up
from within the project directory to initiate the deployment. Pulumi will connect to your Kubernetes cluster using your already-configuredkubectl
context and deploy the chart. Once deployed, it will export the public IP address of the Easegress service if it was exposed as a LoadBalancer.Feel free to add more custom configuration in the
values
field as per your requirements. Also, ensure that you have the correct access permissions to deploy resources to your Kubernetes cluster.
