Deploy the openshift-scc helm chart on Opensshift
TypeScriptTo deploy the
openshift-scc
Helm chart on an OpenShift cluster using Pulumi and the Kubernetes provider, you’ll first need to have access to an OpenShift cluster and havekubectl
configured to communicate with it.The core resource used to manage Helm charts in Pulumi's Kubernetes provider is
Chart
. TheChart
resource is a component that allows you to express Helm Charts as part of your Pulumi program. You can deploy an entire Helm chart as a single Pulumi component (Chart
).Here's how you can use the
Chart
resource to deploy theopenshift-scc
Helm Chart:- First, you'll need to install the Pulumi CLI and set up the Kubernetes provider.
- Make sure you have access to the OpenShift cluster (via
kubectl
). - Write the Pulumi code to deploy the chart.
- Preview and deploy your infrastructure using Pulumi commands:
pulumi up
.
Below is a TypeScript program that demonstrates these steps. It assumes that you have already set up Pulumi and authenticated with your OpenShift cluster:
import * as k8s from "@pulumi/kubernetes"; // You need to replace 'repo_url' with the URL of the Helm repository that contains the 'openshift-scc' chart. const repoUrl = "your_helm_chart_repo_url"; // Create a new instance of the Helm Chart component for the 'openshift-scc' chart. // The 'namespace' should be the namespace where you want the chart to be deployed which could be 'default' // or any custom namespace you have created in your OpenShift cluster. const openshiftSccChart = new k8s.helm.v3.Chart("openshift-scc", { chart: "openshift-scc", version: "chart_version", // Replace with the version of the chart you want to deploy fetchOpts: { repo: repoUrl, }, namespace: "target-namespace", // Replace with the target namespace in your cluster // Include any custom values you wish to override. For example: // values: { // someKey: "someValue", // } }, { provider: new k8s.Provider("k8s-provider", { // This is where you provide the kubeconfig details kubeconfig: `your_kubeconfig_contents`, }), }); // Export the name of the chart namespace which might be handy for operations post deployment export const chartNamespace = openshiftSccChart.namespace;
Replace
your_helm_chart_repo_url
with the actual URL of the repo where theopenshift-scc
chart is located. Additionally, replacechart_version
with the version of the chart you want to deploy,target-namespace
with the namespace where you want the chart to be deployed, andyour_kubeconfig_contents
with the contents of yourkubeconfig
file that contains the connection details to your OpenShift cluster.This program does the following:
- It imports the Kubernetes package from Pulumi.
- It defines the Helm chart to be deployed, specifying the repo URL, chart name, version, and target namespace.
- It configures the Kubernetes provider with
kubeconfig
. - It deploys the Helm chart to your OpenShift cluster.
- It exports the namespace where the chart is deployed.
After writing this code in a file, say
index.ts
, you run the following Pulumi commands to deploy it:pulumi stack init dev pulumi up
The
pulumi stack init
command is used to create a new stack, nameddev
in this case, which will keep track of the state of your infrastructure. Thepulumi up
command is used to preview and deploy the changes.When you run
pulumi up
, Pulumi will perform a preview showing you what resources will be created, modified, or destroyed. Once you confirm the operation, Pulumi will proceed with the deployment.Remember to look at the official documentation for specific configuration parameters relevant to
openshift-scc
that you might need to pass to the Helm chart through thevalues
property: Helm Chart Resource | Pulumi.
