1. Deploy the free5gc helm chart on Azure Managed Openshift Service


    To deploy the free5GC Helm chart on Azure Managed OpenShift Service, we'll follow these steps:

    1. Set up an Azure Managed OpenShift Cluster using Pulumi's azure-native.containerservice.OpenShiftManagedCluster resource.
    2. Deploy the Helm chart to the cluster using Pulumi's kubernetes.helm.v3.Chart resource.

    First, you'd need to have Pulumi and the required cloud provider CLI installed and configured (in this case, az CLI for Azure).

    Here's an overview of what we'll do in the Pulumi program:

    • Define a new Azure Managed OpenShift cluster.
    • Use the Helm provider to deploy the free5GC chart to the OpenShift cluster.

    Before running this code, ensure you import the necessary packages in your Pulumi project using the following commands:

    pulumi plugin install resource azure-native 2.11.0 pulumi plugin install resource kubernetes 4.4.0 npm install @pulumi/azure-native @pulumi/kubernetes

    Now, here is the Pulumi TypeScript program that sets up the OpenShift Managed Cluster and deploys the free5GC application using Helm:

    import * as pulumi from '@pulumi/pulumi'; import * as azureNative from '@pulumi/azure-native'; import * as k8s from '@pulumi/kubernetes'; // Step 1: Create a new Azure Managed OpenShift Cluster const resourceGroupName = 'myResourceGroup'; const openshiftClusterName = 'myOpenShiftCluster'; // Ensure the resource group exists const resourceGroup = new azureNative.resources.ResourceGroup(resourceGroupName, { resourceGroupName: resourceGroupName, location: 'eastus', // Use the location that best suits your needs }); // Create the OpenShift cluster const openshiftCluster = new azureNative.containerservice.OpenShiftManagedCluster(openshiftClusterName, { resourceName: openshiftClusterName, resourceGroupName: resourceGroup.name, location: resourceGroup.location, openShiftVersion: '4.3', // Specify the OpenShift version networkProfile: { vnetCidr: '', }, masterPoolProfile: { count: 3, // Number of master nodes vmSize: 'Standard_D4s_v3', // VM size for master nodes }, agentPoolProfiles: [ { name: 'agentpool', count: 3, // Number of agent nodes vmSize: 'Standard_D4s_v3', // VM size for agent nodes }, ], }); // Step 2: Deploy the free5GC Helm chart to the OpenShift cluster const helmChartName = 'free5gc'; const helmChartVersion = '0.1.0'; // Replace with the version you need const helmChartRepo = 'https://testhelmrepo/helm'; // Replace with the free5GC Helm repo URL // Kubernetes provider to interact with the OpenShift cluster const k8sProvider = new k8s.Provider('k8sProvider', { kubeconfig: openshiftCluster.config.kubeconfigRaw, // Use the kubeconfig from the created OpenShift cluster }); // Deploy the Helm chart using the Helm provider const free5gcChart = new k8s.helm.v3.Chart(helmChartName, { chart: helmChartName, version: helmChartVersion, fetchOpts: { repo: helmChartRepo, }, }, { provider: k8sProvider }); // Export the OpenShift Managed Cluster's kubeconfig export const kubeconfig = openshiftCluster.config.kubeconfigRaw;

    This Pulumi program performs the following actions:

    • It creates a new resource group for your OpenShift Cluster. Change the location to whichever region you prefer.
    • It then defines the Azure OpenShift cluster, specifying the number of nodes and VM sizes for both master and agent pools.
    • It enforces the kubeconfig from the created OpenShift cluster to configure the Kubernetes Pulumi provider.
    • It uses the Kubernetes provider to deploy the free5GC Helm chart to the OpenShift cluster.
    • It finally exports the kubeconfig of the OpenShift cluster, which you can use to interact with your Kubernetes cluster using kubectl.

    Please note that the version and repo URL of the free5GC Helm chart are hypothetical and should be replaced with actual values.

    To apply this program:

    1. Save it as index.ts in your Pulumi project directory.
    2. Run pulumi up to create the resources.

    The pulumi up command will show you a preview of the resources that will be created and prompt you to confirm the deployment. Once confirmed, Pulumi will provision the Azure OpenShift cluster and deploy the free5GC application.
