1. Deploy the witcom-zim helm chart on Digital Ocean Kubernetes Service


    To deploy the witcom-zim Helm chart on Digital Ocean Kubernetes Service (DOKS), you'll need to perform a series of steps:

    1. Create a Kubernetes Cluster on Digital Ocean: This involves provisioning a DOKS cluster with the desired specifications (e.g., number of nodes, size, and region).

    2. Deploy the Helm Chart: Once the cluster is available, you'll use Helm to deploy the witcom-zim chart to your cluster. Assuming you have the Helm chart details like repository URL and any specific chart values, you'll apply them accordingly.

    Let's proceed with the implementation using Pulumi in TypeScript:

    Pulumi Program to Deploy Helm Chart on DOKS:

    import * as pulumi from '@pulumi/pulumi'; import * as digitalocean from '@pulumi/digitalocean'; import * as kubernetes from '@pulumi/kubernetes'; // Step 1: Provision the Digital Ocean Kubernetes Service Cluster const cluster = new digitalocean.KubernetesCluster('do-cluster', { region: 'nyc1', // Replace with your desired region version: 'latest', // Specify the version if needed, or use 'latest' nodePool: { size: 's-2vcpu-2gb', // Replace with the size you need name: 'default-pool', nodeCount: 2, // Specify the number of nodes }, }); // Step 2: Deploy the 'witcom-zim' Helm chart on the provisioned DOKS cluster // We need to use the kubeconfig to connect with our Kubernetes cluster const kubeconfig = cluster.kubeConfigs[0].rawConfig; // Create a Kubernetes Provider instance with the kubeconfig from the DOKS cluster const k8sProvider = new kubernetes.Provider('k8s-provider', { kubeconfig: kubeconfig, }); // Deploy the Helm chart using the kubernetes.helm.v3.Chart resource const helmChart = new kubernetes.helm.v3.Chart('witcom-zim-chart', { chart: 'witcom-zim', // Assuming 'witcom-zim' is available in a public Helm chart repository // or specify `repo` attribute if it's in a private/custom repository. values: { // Specify any custom values needed for 'witcom-zim' Helm chart // e.g., imageTag: "latest", serviceType: "LoadBalancer" }, }, { provider: k8sProvider }); // Export the cluster name and the public service endpoint URL of 'witcom-zim', if available export const clusterName = cluster.name; export const witcomZimServiceEndpoint = pulumi.interpolate`http://${helmChart.getResource('v1/Service', 'witcom-zim').status.loadBalancer.ingress[0].hostname}`;


    • Cluster Creation: The digitalocean.KubernetesCluster resource defines the cluster specifications. KubernetesCluster includes properties for the region, Kubernetes version, and the node pool configuration.

    • Helm Chart Deployment: We use the kubernetes.helm.v3.Chart resource to deploy the witcom-zim Helm chart. The kubeconfig created by the DigitalOcean Kubernetes cluster is used by the Pulumi Kubernetes Provider to manage resources on the Kubernetes cluster. Check out the Chart docs for more details on chart deployment.

    • Exposing Services: If the Helm chart contains a Service of type LoadBalancer, the public endpoint will be made available and exported.

    Remember to replace placeholder values with your actual data. For example, specify your desired Digital Ocean region, the Helm chart repo if it's hosted in a private repository, and any values that the Helm chart requires to tailor the deployment to your needs.
