Deploy the ibm-connect-direct helm chart on Kubernetes
TypeScriptTo deploy a Helm chart on a Kubernetes cluster with Pulumi, you need to have a configured Kubernetes cluster and Helm installed. We'll assume that you have a cluster up and running and are authenticated to use
kubectl
with appropriate permissions.Pulumi interacts with your Kubernetes cluster configuration via the
kubeconfig
file in your environment, which is typically located at~/.kube/config
. If yourkubeconfig
file is in a non-standard location, you will either need to move it or set theKUBECONFIG
environment variable with the path to your cluster configuration.The
@pulumi/kubernetes
package provides aChart
resource that represents a Helm chart. Using this resource, we can deploy a chart to the Kubernetes cluster.Below is a Pulumi program in TypeScript that deploys the "ibm-connect-direct" Helm chart into your Kubernetes cluster. The chart's repository needs to be specified since "ibm-connect-direct" is not available in the stable chart repository.
import * as kubernetes from "@pulumi/kubernetes"; // If your Helm chart is hosted in a Helm repository, you must first add the repository. // For example, to use the Bitnami repo, you would add it using `helm repo add`. // We'll pretend `ibm-helm-repo` is the name of the Helm repository holding `ibm-connect-direct`. const ibmConnectDirectChart = new kubernetes.helm.v3.Chart("ibm-connect-direct", { chart: "ibm-connect-direct", // Replace the `repo` value with the actual Helm repository URL // You may require additional configuration specific to the IBM Connect Direct Helm chart, // such as specifying `values` or `fetchOpts`. repo: "ibm-helm-repo", // You can customize values in the Helm chart by providing a `values` object values: { // Example of setting values // replicaCount: 1, }, // Define the target namespace or remove if you're deploying to the default namespace namespace: "my-namespace", }); // Export the base URL for the deployed IBM Connect Direct (this might vary based on the chart's configuration) export const baseUrl = ibmConnectDirectChart.getResourceProperty("v1/Service", "ibm-connect-direct", "status").apply(s => `http://${s.loadBalancer.ingress[0].hostname}/`);
In this code, the
new kubernetes.helm.v3.Chart
call is what tells Pulumi to deploy the specified chart. Thename
parameter is the unique name that describes this deployment. Thechart
itself represents theibm-connect-direct
Helm chart.Please ensure that you replace
"ibm-helm-repo"
with the actual repository URL where theibm-connect-direct
chart is hosted. Often Helm charts come with custom configuration that you can specify in thevalues
object.The final export of
baseUrl
assumes that the Helm chart deploys aService
of typeLoadBalancer
, and is expecting that the service will provide a single public ingress point. Note that this exact path might vary and can depend on the specifics of the Helm chart and on your Kubernetes environment, particularly if you're working with an ingress controller or need to reference something other than aLoadBalancer
type service.Now, let me explain some of the steps you would usually follow to run this:
- Ensure that you have the Pulumi CLI installed and configured.
- Create a new directory for your project and change into it.
- Run
pulumi new typescript
to create a new Pulumi project using TypeScript. - Replace the auto-generated
index.ts
file with the code above. - Install the necessary dependencies by running
npm install @pulumi/kubernetes
. - Run
pulumi up
to deploy your Helm chart to the cluster.
During
pulumi up
, you will get details about the deployment plan, and Pulumi will await confirmation before proceeding with the actual deployment. Once approved, the Helm chart will be deployed to the targeted Kubernetes cluster, and the resulting base URL will be exported.
