1. Deploy the free5gc helm chart on Digital Ocean Kubernetes Service


    To deploy the free5gc Helm chart on DigitalOcean Kubernetes Service (DOKS), we first need to create an instance of the Kubernetes cluster managed by DigitalOcean. Once we have the cluster, we can deploy the free5gc Helm chart to the Kubernetes cluster.

    In this Pulumi program, we will follow these steps:

    1. Set up a new Kubernetes cluster on DigitalOcean using the digitalocean.KubernetesCluster resource.
    2. Configure the Kubernetes provider to use the created cluster's kubeconfig for deploying the Helm chart.
    3. Use the kubernetes.helm.v3.Chart resource to deploy free5gc from its Helm chart to the Kubernetes cluster.

    Let's start with the Pulumi program written in TypeScript. Make sure you have Pulumi installed and configured with DigitalOcean access credentials.

    import * as pulumi from '@pulumi/pulumi'; import * as digitalocean from '@pulumi/digitalocean'; import * as kubernetes from '@pulumi/kubernetes'; // Step 1: Create a DigitalOcean Kubernetes Cluster const cluster = new digitalocean.KubernetesCluster('do-cluster', { region: 'nyc1', version: '1.21.5-do.0', nodePool: { name: 'default', size: 's-2vcpu-2gb', nodeCount: 3, }, }); // Step 2: Configure a provider to use the created cluster's kubeconfig const k8sProvider = new kubernetes.Provider('k8s-provider', { kubeconfig: cluster.kubeConfigs[0].rawConfig, }); // Step 3: Deploy the free5gc Helm chart const chart = new kubernetes.helm.v3.Chart('free5gc-chart', { chart: 'free5gc', // Assuming the Helm Chart from a known repository url: // e.g., https://helm.free5gc.org/ // It's important to confirm the actual chart name and repository fetchOpts: { repo: 'https://helm.free5gc.org/', }, // Set helm chart values here if needed values: { serviceType: 'LoadBalancer', }, }, { provider: k8sProvider }); // Export the cluster's kubeconfig and the Helm chart's status export const kubeconfig = cluster.kubeConfigs[0].rawConfig; export const chartStatus = chart.status;


    • Step 1: Create a DigitalOcean Kubernetes Cluster: This defines a new Kubernetes cluster on DigitalOcean with the specified region, version, and node pool configuration.

    • Step 2: Configure a Provider: This step configures the Kubernetes provider to interact with the newly created DigitalOcean cluster. It utilizes the kubeconfig obtained from the cluster to authenticate.

    • Step 3: Deploy the free5gc Helm Chart: This step deploys free5gc using its Helm chart. It uses the repository where the Helm chart is located (you must replace with the correct repository URL), and you can also specify Helm chart values to customize the deployment.


    • The region, version, and nodePool configuration should be adjusted as per your specific requirements and DigitalOcean's available options.
    • Confirm the name of the free5gc Helm chart and its repository URL. In this example, we used placeholder names.
    • You can customize the values field of the Chart resource to include any configurations that are specific to free5gc and your use case.
    • The exported kubeconfig will be used to access the cluster with kubectl or other Kubernetes tools.
    • The chartStatus export can give you the deployment status information which can be useful for programmatic validation or logging.

    To deploy your infrastructure, you must execute this program using the following Pulumi CLI commands:

    pulumi up # Preview and deploy changes pulumi stack output # View stack outputs pulumi destroy # Destroy the resources

    Remember to review the Helm chart's documentation for any specific configuration options required for free5gc.
