Deploy the old-joomla helm chart on Kubernetes
TypeScriptDeploying the old-joomla Helm Chart on Kubernetes with Pulumi
Helm Charts provide a way to deploy and manage applications on a Kubernetes cluster. With Pulumi, you can orchestrate the deployment of Helm charts programmatically. We'll use Pulumi's Kubernetes provider to deploy the "old-joomla" Helm chart, which is a package that encapsulates the Joomla application, its dependencies, and its deployment configuration.
We will go through the process of setting up a Pulumi program in TypeScript that accomplishes this. The program will:
- Set up a Kubernetes Provider that interacts with your cluster.
- Use the
Chart
resource from the Pulumi Kubernetes provider to deploy the "old-joomla" Helm chart.
Before you start, make sure you have the following prerequisites in place:
- Pulumi CLI installed and configured with your chosen cloud provider.
- Access to a Kubernetes cluster (with
kubectl
configured to connect to it). - Helm tool installed (used to locate the "old-joomla" chart's repository or for local chart paths).
Here is the TypeScript program that deploys the "old-joomla" Helm chart to your Kubernetes cluster:
import * as k8s from "@pulumi/kubernetes"; const chartName = "old-joomla"; const chartVersion = "x.y.z"; // Replace x.y.z with the chart's version you wish to deploy const chartRepo = "https://charts.bitnami.com/bitnami"; // Replace with the repository URL where the chart is hosted // Deploying the old-joomla Helm chart to the Kubernetes cluster const joomlaChart = new k8s.helm.v3.Chart("old-joomla-chart", { chart: chartName, version: chartVersion, fetchOpts: { repo: chartRepo }, // Specify the values you'd like to override. // This would be equivalent to the --set flag when using the Helm CLI. values: { // Add custom values here which are specific to the old-joomla chart // e.g., cpu: "100m" } }); export const joomlaChartName = joomlaChart.metadata.name;
In this program:
- We import the Kubernetes package from Pulumi which allows us to interact with our cluster.
- We declare constants for the name, version, and repository URL of the chart we're deploying. You must replace "x.y.z" with the actual version of the "old-joomla" chart you want to deploy.
- The
k8s.helm.v3.Chart
class is instantiated to create a new Helm chart resource. The chart's name, version, and repository options are provided to locate the correct Helm chart. - Within the
values
object of the chart, you can provide overrides for default Helm chart values. This step is optional and depends on the configuration you would like for Joomla. - We export the name of the deployed Helm chart to use as a reference if needed.
To deploy this program:
- Save the code to a file with a
.ts
extension, for example,deployJoomla.ts
. - Run
pulumi up
in the same directory as your.ts
file. Pulumi CLI will interact with your Kubernetes cluster to deploy the chart.
After you run
pulumi up
, Pulumi performs the deployment, and you should see outputs indicating the status of the resources being deployed. If you've set everything up correctly, "old-joomla" should be deployed to your Kubernetes cluster.Remember to replace the
chartVersion
andchartRepo
with actual versions and repository URLs. You can find the "old-joomla" Helm chart info and available versions from Helm chart repositories or artifact hubs that host Helm charts.
