Deploy the simple-grafana helm chart on Opensshift
TypeScriptTo deploy the simple-grafana Helm chart on OpenShift using Pulumi, you would typically:
- Set up access to your OpenShift cluster in Pulumi.
- Use the
@pulumi/kubernetes
package to create a Helm Release resource that points to the simple-grafana chart.
Here's a detailed explanation of the steps followed by the Pulumi program written in TypeScript:
Prerequisites:
- Install Pulumi CLI and set it up for use.
- Configure
kubectl
to connect to your OpenShift cluster.
Steps:
-
Setting Up Your Pulumi Project: You'd start by creating a new Pulumi project or navigating to an existing one.
-
Adding Dependencies: You would ensure that the
@pulumi/kubernetes
package is added to your project to interact with the Kubernetes API. -
Writing the Pulumi Program:
- Import the necessary libraries.
- Create a
kubernetes.helm.v3.Chart
resource that represents your Helm deployment. - Specify the Helm chart name, in this case, "simple-grafana" and the other details such as repository, chart version, release name, and any specific configurations if needed.
- If you need to pass custom values to the Helm chart, they can be specified in the
values
property.
-
Deploying Your Chart:
- You'll run
pulumi up
to preview and deploy your changes. - Upon a successful deployment, Pulumi will ensure that the simple-grafana Helm chart is deployed onto your OpenShift cluster.
- You'll run
Here is the complete program that does this:
import * as k8s from '@pulumi/kubernetes'; // Initialize a new or existing Pulumi project using your kubeconfig credentials. const provider = new k8s.Provider('openshift-provider', { kubeconfig: process.env.KUBECONFIG, // Ensure that your KUBECONFIG environment variable is set. }); // Deploy the simple-grafana Helm chart using Pulumi's Kubernetes provider. const grafanaChart = new k8s.helm.v3.Chart('simple-grafana', { chart: 'grafana', // The name of the chart version: '6.1.14', // The version of the chart fetchOpts: { repo: 'https://grafana.github.io/helm-charts', // Helm repository URL }, // Set the values for the Helm chart values: { // For example, to set the admin password you would add: // adminPassword: 'your-admin-password', // Any other Grafana Helm chart values can be set here in the values object. }, }, { provider: provider }); // Export the URL of the Grafana instance // You need to know the service name and namespace to construct the URL. export const grafanaUrl = `http://simple-grafana.<namespace>.svc.cluster.local`; // Replace <namespace> with your actual namespace
Run this program using the
pulumi up
command, which will provision the resources on your OpenShift cluster according to the configuration defined in the chart.Notes:
- You may need to customize the values and version to match your requirements.
- Make sure to replace
<namespace>
with your actual namespace where the Grafana instance will be accessible. - Check the Helm chart documentation for the exact configurable values:
grafana
.
By following these steps and running this TypeScript program using the Pulumi CLI, you will be able to deploy the simple-grafana Helm chart on your OpenShift Cluster.
