Deploy the ibm-glusterfs helm chart on Kubernetes
TypeScriptTo deploy a Helm chart to a Kubernetes cluster using Pulumi, you can use the
Chart
resource from the@pulumi/kubernetes
package. TheChart
resource is a high-level component that enables you to deploy Helm charts from repositories or local paths.In the following TypeScript Pulumi program, I'll show you how to deploy the
ibm-glusterfs
Helm chart. Assuming you have already set up the Kubernetes cluster and configured Pulumi to use the right kubeconfig context, the following program will deployibm-glusterfs
to your cluster.First, you'll need to install the necessary Pulumi package by running:
npm install @pulumi/kubernetes
Here is the program that will perform the deployment:
import * as k8s from '@pulumi/kubernetes'; // Deploying the `ibm-glusterfs` Helm chart into a Kubernetes cluster. // Create a Kubernetes namespace for the `ibm-glusterfs` deployment. const namespace = new k8s.core.v1.Namespace("glusterfs-ns", { metadata: {name: "glusterfs"}, }); // Deploy `ibm-glusterfs` Helm chart from the Helm repository. const glusterfsChart = new k8s.helm.v3.Chart("glusterfs-chart", { namespace: namespace.metadata.name, chart: "ibm-glusterfs", version: "<CHART_VERSION>", // Specify the version of the chart you wish to deploy fetchOpts: { repo: "https://charts.bitnami.com/bitnami", // Use the helm repository where `ibm-glusterfs` is stored }, // Include any custom values you wish to override in the chart here. // For example: `values: { persistence: { size: "10Gi" } }` }, {dependsOn: namespace}); // Export the namespace name and Helm chart resources. export const glusterfsNamespace = namespace.metadata.name; export const glusterfsChartResources = glusterfsChart.resources;
Replace
<CHART_VERSION>
with the specific version of theibm-glusterfs
chart that you want to deploy.This program does the following:
- It imports the necessary Pulumi Kubernetes SDK.
- It creates a new Kubernetes namespace called
glusterfs
where our Helm chart will be deployed. This is a best practice, helping to isolate our deployment. - It then creates a
Chart
resource namedglusterfs-chart
using the Helm v3 API.- The
namespace
specifies where the chart will be deployed. - The
chart
is the name of the chart to deploy, in this case,ibm-glusterfs
. - The
version
is where you specify the chart version. - The
fetchOpts
include the repository from which to fetch the chart. You should replace therepo
URL with the actual repository URL containing theibm-glusterfs
chart.
- The
- The
values
object within theChart
resource can be used to specify any configuration values that are specific to theibm-glusterfs
chart. - It declares dependencies explicitly by using the
dependsOn
option, ensuring the namespace is created before the chart is deployed. - It exports the namespace and chart resource details.
Please note that the actual
repo
URL foribm-glusterfs
may differ; the provided URLhttps://charts.bitnami.com/bitnami
is an example, and you will have to replace it with the valid repository URL.After writing this Pulumi program to a file (for example,
index.ts
), you can deploy the Helm chart to your cluster using the Pulumi CLI with the following commands:pulumi up
Running
pulumi up
will initiate the deployment process where Pulumi performs a preview and then asks for confirmation before applying the changes. Once confirmed, it will deploy theibm-glusterfs
Helm chart to your Kubernetes cluster.
