Deploy the identity helm chart on Azure Managed Openshift Service
TypeScriptTo deploy an identity Helm chart on Azure Managed OpenShift Service using Pulumi, we'll be focusing on two key components: the Azure Managed OpenShift Service and the Helm chart deployment on Kubernetes. We'll first set up an Azure Red Hat OpenShift cluster, and then deploy a Helm chart into this cluster which presumably contains the identity management components we're interested in.
The
azure-native.redhatopenshift.OpenShiftCluster
resource will be used to create an Azure Red Hat OpenShift Service cluster. It requires setting several properties like network, master and worker profiles, along with authentication details. Once the cluster is up, we can deploy a Helm chart to it using thekubernetes.helm.v3.Chart
resource from thekubernetes
provider.Here's a program in TypeScript to achieve this:
import * as pulumi from "@pulumi/pulumi"; import * as azureNative from "@pulumi/azure-native"; import * as k8s from "@pulumi/kubernetes"; // Create a resource group for the OpenShift cluster const resourceGroup = new azureNative.resources.ResourceGroup("rg", { resourceGroupName: "openshiftResourceGroup", location: "East US", // Change this to the desired Azure region }); // Create an Azure Red Hat OpenShift cluster const openshiftCluster = new azureNative.redhatopenshift.OpenShiftCluster("openshiftCluster", { resourceGroupName: resourceGroup.name, resourceName: "openshiftCluster", location: resourceGroup.location, // Define the properties of the cluster here, including where it will live in terms of VNet and Subnet, and size. // Since these are specific to your environment, you'll want to adjust these as per your requirements. masterProfile: { vmSize: "Standard_D4s_v3", subnetId: "/subscriptions/{subscriptionId}/resourceGroups/{rg}/providers/Microsoft.Network/virtualNetworks/{vnet}/subnets/{subnet-name}", }, // You should configure the network profile as per your organization's networking setup networkProfile: { podCidr: "10.42.0.0/16", serviceCidr: "10.41.0.0/17", }, workerProfiles: [{ name: "workerprofile", count: 3, vmSize: "Standard_D4s_v3", subnetId: "/subscriptions/{subscriptionId}/resourceGroups/{rg}/providers/Microsoft.Network/virtualNetworks/{vnet}/subnets/{subnet-name}", }], clusterProfile: { domain: "example.com", version: "4.3.0", // Specify the OpenShift version resourceGroupId: resourceGroup.id, }, servicePrincipalProfile: { clientId: "service-principal-client-id", clientSecret: "service-principal-client-secret", }, // Include other necessary parameters... }, { dependsOn: [resourceGroup] }); // Now that we have an OpenShift cluster, we need the Kubernetes provider to interact with it. const k8sProvider = new k8s.Provider("k8sProvider", { kubeconfig: openshiftCluster.kubeconfig.apply(kubeconfig => kubeconfig.rawData), }); // Deploy the identity Helm chart on the OpenShift cluster. const identityChart = new k8s.helm.v3.Chart("identityChart", { chart: "identity", version: "1.0.0", // specify the version of the chart fetchOpts: { repo: "http://your-helm-chart-repo/", // specify your Helm chart repository URL }, // You can provide additional Helm values here for customizing the identity chart. values: { some: "value", // other custom values for your identity chart }, }, { provider: k8sProvider }); // Export the OpenShift cluster's kubeconfig export const kubeconfig = openshiftCluster.kubeconfig.apply(kubeconfig => kubeconfig.rawData);
In this program:
- We set up a new resource group and Azure Red Hat OpenShift cluster using the
ResourceGroup
andOpenShiftCluster
classes respectively from theazure-native
package. You need to replace placeholder values (like{subscriptionId}
,{rg}
,{vnet}
, and{subnet-name}
) with actual values from your environment. - We configure the necessary properties for the cluster such as the VM size for the master and worker nodes, as well as networking details such as the pod CIDR and service CIDR.
- We initialize a new Kubernetes provider linked to our OpenShift cluster, which allows Pulumi to interact with the OpenShift Kubernetes API.
- We deploy the identity Helm chart to the OpenShift cluster with the
Chart
class from thekubernetes.helm.v3
package. You need to use actual values for your chart version and repository URL in theversion
andfetchOpts.repo
fields, respectively. - Finally, we export the kubeconfig that can be used to manage the Kubernetes resources on the OpenShift cluster.
Remember to replace the placeholder values with real information from your Azure subscription and Helm chart. The kubeconfig of the cluster is exported so that you can interact with your cluster with kubectl or other Kubernetes tools.
