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

    TypeScript

    To deploy the OpenSIPS Helm chart on Digital Ocean's Kubernetes Service using Pulumi, you'll need to create a Kubernetes cluster on Digital Ocean and then deploy a Helm chart to it. Here is a step-by-step guide including a TypeScript program that will accomplish this:

    1. Set Up Pulumi: Ensure that you have Pulumi CLI installed and configured with the appropriate cloud provider credentials.

    2. Define the Kubernetes Cluster: Define a Digital Ocean Kubernetes cluster by creating an instance of digitalocean.KubernetesCluster. This component represents a Kubernetes cluster in Digital Ocean and will create and manage the underlying resources required for the cluster.

    3. Deploy the OpenSIPS Helm Chart: After the cluster is provisioned, utilize the kubernetes.helm.v3.Chart component, which allows you to deploy Helm charts within your Kubernetes cluster. A Helm chart is a collection of pre-configured Kubernetes resources that are used to deploy applications.

    Here is the TypeScript program that defines the necessary Pulumi resources to deploy an OpenSIPS Helm chart on a Digital Ocean Kubernetes service:

    import * as pulumi from "@pulumi/pulumi"; import * as digitalocean from "@pulumi/digitalocean"; import * as kubernetes from "@pulumi/kubernetes"; // Step 1: Create a new Digital Ocean Kubernetes cluster const cluster = new digitalocean.KubernetesCluster("do-cluster", { region: "nyc1", // Confirm the region you'd like to deploy the cluster in version: "1.21.5-do.0", // Use an appropriate K8s version available on DigitalOcean nodePool: { name: "worker-pool", size: "s-2vcpu-4gb", // Choose the appropriate size for your workloads nodeCount: 2, // Set the number of nodes you want in your node pool }, }); // Step 2: Use the created cluster's kubeconfig to interact with the cluster const provider = new kubernetes.Provider("k8s-provider", { kubeconfig: cluster.kubeConfigs[0].rawConfig, }); // Step 3: Deploy the OpenSIPS Helm chart on the Kubernetes cluster const openSipsChart = new kubernetes.helm.v3.Chart("opensips", { chart: "opensips", version: "x.y.z", // Replace with actual chart version fetchOpts:{ repo: "https://helm.opensips.org/", // Use the chart's repository URL }, }, { provider }); // Export the cluster's kubeconfig and OpenSIPS service endpoint export const kubeconfig = cluster.kubeConfigs[0].rawConfig; export const openSipsServiceIp = openSipsChart.getResourceProperty( "v1/Service", "opensips", "status").apply(status => status.loadBalancer.ingress[0].ip);

    Before running this Pulumi program, verify the following:

    • The Digital Ocean token is set up correctly in the Pulumi configuration or through environment variables.
    • The Helm chart version x.y.z and chart repository https://helm.opensips.org/ are placeholders. You will need to use the actual values for the OpenSIPS chart you want to deploy.

    After this program is run with pulumi up, Pulumi will perform the following actions:

    • Provision a new Kubernetes cluster on Digital Ocean.
    • Configure Pulumi to interact with the newly created Kubernetes cluster.
    • Deploy the specified version of the OpenSIPS Helm chart to the cluster.

    Once the deployment is complete, Pulumi will output the cluster's kubeconfig and the IP address for accessing your OpenSIPS service.
