Deploy the zimagi-lib helm chart on Opensshift
TypeScriptDeploying a Helm chart into an OpenShift cluster involves a few steps. Below is a general overview of the process along with a TypeScript program using the Pulumi Kubernetes provider. This example assumes that you have already set up access to your OpenShift cluster and have the necessary context configured in your local
kubeconfig
file.Here's a step-by-step guide to the code:
- First, import the necessary Pulumi and Kubernetes packages.
- Then, create an instance of the
Chart
class from the Pulumi Kubernetes package. TheChart
resource is a component resource that represents a collection of Kubernetes resources as defined by a Helm Chart. It can be deployed into a Kubernetes cluster usingkubectl apply
, and Pulumi automates this process.
In the constructor of the
Chart
class, you define:- The
chart
parameter, which specifies the name of the Helm chart. - The
version
parameter, which specifies the version of the Helm chart. (optional) - The
values
parameter, which allows you to overrule the default values provided by the Helm chart with your own values. (optional) - The
fetchOpts
parameter, where you can specify the repository if the Helm chart comes from a Helm repository other than the default one.
Please replace
"YOUR_NAMESPACE"
with the namespace you want to deploy to in OpenShift, and"HELM_REPO_URL"
with the URL of the Helm repository where thezimagi-lib
chart is located, if it's not a chart from the default Helm repository.import * as kubernetes from "@pulumi/kubernetes"; // Deploying a Helm chart on OpenShift cluster const zimagiLibChart = new kubernetes.helm.v3.Chart("zimagi-lib-chart", { // Replace `YOUR_NAMESPACE` with your target namespace in the OpenShift cluster namespace: "YOUR_NAMESPACE", // Assuming 'zimagi-lib' is the chart name; specify the version if needed chart: "zimagi-lib", // Specify the repository URL where 'zimagi-lib' chart can be found // Replace `HELM_REPO_URL` with the URL to your Helm chart's repository fetchOpts: { repo: "HELM_REPO_URL", }, // Include any custom values (overriding default values in the chart) here values: { // For example, set a custom value: // someCustomValue: "custom-setting", }, }); export const chartName = zimagiLibChart.metadata.name;
This code block would create a new Helm chart deployment in your OpenShift cluster. The
export
at the end of the program is used to output the name of the deployed chart so you can quickly reference it using Pulumi CLI commands, such aspulumi stack output chartName
.To run this Pulumi program:
- Ensure Pulumi CLI and
kubectl
are installed. - Set up your Pulumi stack and select your OpenShift environment.
- Place the TypeScript code into a file named
index.ts
. - Run
pulumi up
to preview and deploy the resources.
Remember to replace placeholder strings like
"YOUR_NAMESPACE"
and"HELM_REPO_URL"
with actual values before running the program. If the chart requires additional values for the configuration, define them in thevalues
field.
