Deploy the docker-registry-proxy helm chart on Opensshift
TypeScriptTo deploy the
docker-registry-proxy
Helm chart on an OpenShift cluster using Pulumi, we will use thekubernetes.helm.v3.Chart
resource from the Pulumi Kubernetes provider. This resource allows us to deploy Helm charts into a Kubernetes cluster managed by Pulumi.Here are the steps to accomplish this with Pulumi and TypeScript:
-
First, make sure you have access to your OpenShift cluster from your local machine using
kubectl
oroc
. Pulumi uses your local Kubernetes configuration to interact with the cluster. -
Ensure that Pulumi is installed on your local machine, and you are logged in to the Pulumi service where your state will be stored.
-
Create a new Pulumi project or use an existing one.
-
In your Pulumi TypeScript program, you will import necessary packages, create a
kubernetes.Provider
for OpenShift if needed, and deploy the Helm chart using thekubernetes.helm.v3.Chart
resource.
Here's an example program that demonstrates how to do this:
import * as pulumi from "@pulumi/pulumi"; import * as kubernetes from "@pulumi/kubernetes"; // You may specify your OpenShift provider configuration explicitly, if required. // For example, if you need specific access rights or if you are managing multiple clusters. // The configuration might reference an existing kubeconfig file or the cluster's context. const openshiftProvider = new kubernetes.Provider("openshift", { // If needed, set the kubeconfig or context here. // By default, Pulumi utilizes the kubeconfig file from the default location (~/.kube/config). }); // Now we will define the Helm chart for the docker-registry-proxy. // Ensure that you have the correct repository and chart name. const dockerRegistryProxyChart = new kubernetes.helm.v3.Chart("docker-registry-proxy", { chart: "docker-registry-proxy", // Specify the Helm repository details where the `docker-registry-proxy` chart is located. // This can be an URL or a repository alias after adding it via `helm repo add`. fetchOpts: { repo: "https://your-repo-url/", }, // Specify the namespace where the chart will be installed. // This assumes the namespace is already created in your OpenShift cluster. namespace: "your-target-namespace", }, { provider: openshiftProvider }); // If you want to make your OpenShift service endpoints or other resources created by this Helm chart available, // simply export them using Pulumi stack outputs. export const registryProxyEndpoint = dockerRegistryProxyChart.getResourceProperty("v1/Service", "docker-registry-proxy", "status").apply(status => status.loadBalancer.ingress[0].ip); // Run `pulumi up` to deploy this stack to your OpenShift cluster.
This program sets up the Pulumi Kubernetes provider to interact with your OpenShift cluster, and it defines a Helm chart resource pointing to the
docker-registry-proxy
. Make sure to replacehttps://your-repo-url/
with the actual Helm chart repository URL andyour-target-namespace
with the namespace you want to deploy.Please note that you might have to adjust the chart and repository specifics depending on where and how
docker-registry-proxy
is hosted.Before running
pulumi up
, initialize a Pulumi project if you haven't already:pulumi new typescript --dir my-openshift-deployment cd my-openshift-deployment
Replace the contents of
index.ts
with the code above, then runpulumi up
. Pulumi will perform the deployment based on the provided program. Make sure you're logged into the correct Pulumi account and have configured access to your OpenShift cluster.-
