Deploy the kubeaddons-catalog helm chart on Opensshift
TypeScriptTo deploy the
kubeaddons-catalog
Helm chart on OpenShift using Pulumi, you would use thekubernetes.helm.v3.Chart
resource from the Pulumi Kubernetes provider. TheChart
resource allows you to deploy Helm charts in a declarative way.Before you proceed with the deployment, make sure you have the following prerequisites met:
- Pulumi CLI installed.
kubectl
command-line tool installed and configured to connect to your OpenShift cluster.- Helm CLI installed, if you need to customize the chart or use the
helm
tool for any preparatory steps.
Here's a detailed explanation of the process along with a Pulumi TypeScript program that you can use to deploy the
kubeaddons-catalog
:-
Install the Pulumi Kubernetes Provider: The provider is what allows Pulumi to communicate with your Kubernetes cluster. To do this, you will need to add the Pulumi Kubernetes SDK to your Pulumi project.
-
Create a Helm Chart resource: This represents the Helm chart you want to deploy. You will specify the chart name, version (if you want a specific version), and the repository where the chart is located. If the
kubeaddons-catalog
chart requires it, you will also provide any necessary configuration values via thevalues
property. -
Configure the namespace: Decide in which namespace on your OpenShift cluster you want to deploy the chart. If the namespace doesn't exist, you can create it using Pulumi as well.
Below is the Pulumi TypeScript program that accomplishes the deployment:
import * as pulumi from "@pulumi/pulumi"; import * as k8s from "@pulumi/kubernetes"; // Initialize Pulumi Kubernetes provider to connect to the OpenShift cluster // This will use the current context in your kubeconfig const provider = new k8s.Provider("openshift-provider", {}); // Create a namespace for the kubeaddons-catalog if it doesn't already exist const namespace = new k8s.core.v1.Namespace("kubeaddons-namespace", { metadata: { name: "kubeaddons" // Provide the name for the namespace }, }, { provider }); // Deploy the kubeaddons-catalog Helm chart const kubeaddonsChart = new k8s.helm.v3.Chart("kubeaddons-catalog", { chart: "kubeaddons-catalog", // The name of the Helm chart version: "1.0.0", // Specify the chart version here namespace: namespace.metadata.name, // Target namespace // Define repository options if your Helm chart is hosted in a custom repo fetchOpts:{ repo: "https://<helm-chart-repo>.com/charts", // Replace with the actual Helm repository URL }, values: { // Provide any custom configuration for the chart here // Each key-value pair corresponds to chart configuration options }, }, { provider }); // To access the deployed Helm chart, you may want to have outputs like the service endpoint export const kubeaddonsEndpoint = pulumi.interpolate`http://<your-service>.${namespace.metadata.name}.svc.cluster.local`; // Note that "<your-service>" should be replaced by the actual service DNS name if you need to access it
In this program:
- The
k8s.Provider
object initializes and represents the connection to your OpenShift cluster. - The
k8s.core.v1.Namespace
object creates a new namespace in the cluster. Themetadata
property specifies the namespace name. - The
k8s.helm.v3.Chart
object deploys the Helm chart. In thefetchOpts
property, you specify the repository containing the chart. - Finally, the
export
statement defines an output variable that can be used to obtain information about the deployed resources. In this case, it's a fictive endpoint, and you would replace<your-service>
with the actual service you are trying to access from thekubeaddons-catalog
.
Replace the placeholders
<helm-chart-repo>.com/charts
and<your-service>
with the appropriate values for the Helm chart repository and the service DNS name within the deployed chart that you are trying to access, respectively.Please note that if your Helm chart requires custom configurations, you'll need to fill out the
values
object with the appropriate key-value pairs as per your Helm chart's configurable parameters.
