Deploy the jenkins-x-platform helm chart on Kubernetes
TypeScriptTo deploy the Jenkins X platform using a Helm chart on a Kubernetes cluster, you will utilize the
Chart
resource from the Pulumi Kubernetes provider. Jenkins X is a powerful CI/CD system designed for Kubernetes. It can be installed via Helm, which is a package manager for Kubernetes that allows easy installation and management of applications.To use the
Chart
resource, you need to provide values for:- the name of the Helm chart (
jenkins-x-platform
in this case), - the repository where the Helm chart is located,
- any custom values you wish to configure,
A Pulumi program to deploy
jenkins-x-platform
on Kubernetes might look like this:import * as k8s from "@pulumi/kubernetes"; // Create a Kubernetes namespace for Jenkins X. const jxNamespace = new k8s.core.v1.Namespace("jx", { metadata: { name: "jx" // The namespace where Jenkins X will be installed }, }); // Deploy Jenkins X using the Helm Chart. // You must have Helm and its server-side component, Tiller, set up in your cluster. const jenkinsXChart = new k8s.helm.v3.Chart("jenkins-x", { chart: "jenkins-x-platform", // The name of the chart version: "2.0.1369", // Specify the version of the Helm Chart to use namespace: jxNamespace.metadata.name, // Deploy within the created namespace fetchOpts: { // Specify the repository containing the jenkins-x-platform chart repo: "https://jenkins-x-charts.github.io/v3-dev/" }, // Provide any custom values you want to pass to the Helm chart values: { // For example, if you want to set a custom domain // domain: "example.com", // and any other configuration values that jenkins-x-platform chart supports. }, }, { provider: /* a kubernetes provider if not using the default one */ }); // Export the generated YAML manifest of Helm chart resources. export const jenkinsManifest = jenkinsXChart.resources;
Here's a breakdown of what we're doing in this Pulumi program:
-
We import the
@pulumi/kubernetes
package which allows us to work with Kubernetes resources in Pulumi. -
We create a Kubernetes namespace called
jx
where all the resources related to Jenkins X will be created. -
We instantiate a
Chart
object,jenkinsXChart
, which represents the jenkins-x-platform Helm chart. TheChart
is given several fields:chart
: Specifies the name of the chart to install; in our case, "jenkins-x-platform".version
: Specifies the version of the Helm chart to use; it should be set to a specific version to ensure idempotent deployments.namespace
: Indicates the namespace where the chart should be deployed. We deploy it to the namespace we created earlier.fetchOpts.repo
: Specifies the repository where the Helm chart is located. Make sure to use the correct repository URL for the Jenkins X Helm chart.values
: This field would contain customization for the Helm chart. In this example, it's a placeholder for you to fill in your configuration parameters based on the Jenkins X chart’svalues.yaml
file.
To apply this Pulumi program, save it to a
index.ts
file, set up the Kubernetes context for your Pulumi program to access your cluster, and then runpulumi up
. This will start the deployment of Jenkins X into your Kubernetes cluster.
Please ensure that you have Helm and Tiller properly installed and configured in your cluster, as it's a prerequisite for deploying charts with Pulumi. Additionally, make sure you have a Kubernetes cluster running and
kubectl
configured to connect to it. The Pulumi Kubernetes provider useskubectl
to interact with the cluster.- the name of the Helm chart (
